Stacy Page asked:


If you’re like most consumers today, you’re probably thinking it’s time to upgrade from your standard hard drive to the latest in storage technology—a solid state hard drive. After reading this article, you’ll be more familiar with solid state drives (SSD), including the advantages and disadvantages of this new technology.

What is a Solid State Drive?

The term “solid state” refers to electronic circuitry that is built entirely out of semiconductors rather than magnetic media. This shift in technology is now possible because of the growth in flash chips. Although solid state drives use the same type of memory chips as flash memory drives, SSDs reside inside the computer in place of a more traditional hard drive. These data storage devices utilize non-volatile flash memory for computing applications that traditionally rely on a mechanical hard disk drive. 

Unlike conventional hard drives, SSDs are built with 100% moving-free parts that are housed in a vibration and shock-resistance covering. These components provide a rock solid operating environment even during extreme working conditions, making it a perfect solution for a wide range of applications that require ruggedness, minimal power consumption, cooler temperature, and silent operation. 

Benefits

Solid state drives have several advantages, the majority of which come from the fact that the drive does not have any moving parts. Three distinct advantages include:

·        Less power usage

·        Faster data access

·        Higher reliability

The power usage is a key role for the use of solid state drives in portable computers. Because there is no power draw for the motors, the drive uses far less energy than the regular hard drive, improving battery operating time in notebook PCs and portable electronic devices. When you are on the go, this extra battery life will be extremely handy.

And since the drive doesn’t have to spin up the drive platter or move drive heads, the data can be read from the drive almost instantly. Meaning, you can access your files and data more quickly. You’ll enjoy a boost in performance when starting up your computer and opening applications.

Reliability is also a key factor for portable drives. Because the SSD stores all of its data in memory chips, there are fewer moving parts to be damaged in any sort of impact. These drives also have extreme shock and vibration tolerance, and their operating temperature ranges meet or exceed that of standard hard drives.

When all’s said and done, there are many benefits to this newer technology. Information can be stored permanently in flash chips even when the power is turned off, and the chips can be electrically erased and reprogrammed. Also, they make no noise, give off little heat and consume far less power, while transferring data many times faster than hard disks.

Drawbacks

Of course, not every PC owner can upgrade to a solid state drive. As with most computer technologies, the primary limiting factor of using the SSD in notebook and desktop computers is cost. This is gradually changing as the number of companies producing the drives grows along with the capacity for producing the flash memory chips.

The other problem affecting the adoption of solid state drives is capacity. Not only are the SSDs much more expensive than traditional hard drives, but they only hold a fraction of the data.

Their last major disadvantage involves write speeds, which are far slower than conventional hard drives and therefore vulnerable to write fragmentation. That means that, on average, performance comparisons may depend on a particular manufacturer’s design or running a specific application.

The Bottom Line

So if you want fast data access, less power consumption and higher reliability, then you should consider upgrading your standard hard drive to a solid state drive. You’ll experience nothing but fast, quiet and ultra-reliable solution for your data storage needs. Whether you need it for your enterprise, corporate, or IT infrastructure applications, the solid state hard drives provide the durability and performance quality you need.

Yung Trang asked:


Adding a nice chunk of extra storage space for your computer with a new hard drive can be exciting, like getting a storage shed for the back yard to store and organize tools and toys. However, there are more reasons than storage capacity to buy a hard drive, and size isn’t the only thing that matters when comparing your options.

Why Buy a Hard Drive?

Most people buy hard drives out of necessity – their current hard drive is old or too small or doesn’t work at all. Or they may have recently purchased a computer that came with a drive that had limited storage, so they want to swap the drive out for a bigger one. Smart computer users may buy extra hard drives as a backup solution; and demanding techies and gamers may upgrade their drive for optimal performance.

Jump drives / flash drives / thumb drives and online storage are other popular options for storing and transporting data, but are generally considered to be less robust, temporary solutions compared to hard drives. They are intended to complement a hard drive rather than replace one.

Hard Drive Features

Whatever their reasons for buying a hard drive, shoppers usually compare the following features:

Storage Capacity

At first, those 80 gigabytes of storage may seem like way more than necessary, but as software is added, files are created and information is downloaded, those GBs will fill up fast. Then it’s time to either clean stuff out or buy an additional “container”. So for capacity’s sake, it’s better to go bigger.

Like any storage space, hard drives work best when well-organized so that time is not wasted in search of pieces and parts. Dividing a large hard drive into smaller partitions can help, but the bigger the space, the longer it takes to search it – each and every time. By using several smaller drives instead of one big one, storage capacity is unlimited, backups of data can be made easily, and performance is not sacrificed for size. This is accomplished with RAID (Redundant Array of Independent Disks) technology, where multiple hard drives are grouped together so the computer sees them as one. RAID controllers are bought separately to manage the array (multiple drives).

Speed / Portability



Hard drives have platters that spin, and a read/write head or “needle” that reads them like a record player. Hard drives that

· have platters that spin faster (at higher RPM)

· can transfer information faster (media transfer rate)

· use less power

· are connected to the computer with speed-optimizing cables or cards

These drives can make a big difference in overall computer speed.

Some drives are installed inside a computer, while others can be connected externally. Portable or external hard drives are designed for frequent transport between computers. They generally hold much more information than the largest jump/flash/thumb drives. A general rule for choosing between them is: installed drives perform faster because it takes less time for them to exchange messages with the computer.

Shock Resistance / Heat / Sound

A hardy hard drive goes a long way toward preventing data loss. Shock resistance – how well a hard drive can take being dropped, banged, etc. – is especially important when considering portable drives. This is another good reason for a primary drive to be installed in a computer rather than connected externally.

High-powered drives can generate a lot of heat, which can reduce the life of the drive. The faster or hotter the drive, the more cooling is required. Ways of managing temperature include installing extra fans or upgrading, making sure vents are not covered, and keeping the computer well ventilated, in a cooler room and off the floor.

Some hard drives, especially faster ones or those that are bigger in physical size, can generate a lot of noise. To cut down on noise, look for low-noise disks, compare dBa levels and store the computer in a cabinet rather than out in the open.

Backup / Reliability

Extra hard drives — especially portable ones — make great backup solutions. Hard drives used primarily for backup should provide enough storage space to keep three copies of the main drive. For example, if a primary hard drive holds 100 gigabytes, but only 30 gigs are being used, backup drive space should total 90 GB to allow for multiple backups of all software and files. (See the discussion of RAID technology in Storage Capacity above.)

Backups should also be replicated across different technologies. Using a combination of an extra hard drive or RAID array, online data backup and a flash drive for critical information prevents loss of data from mechanical malfunction, loss of that tiny little flash drive, or environmental factors like flooding or fire.

Techie Tip: Don’t put the cart before the horse! The fastest, biggest hard drive is only as good as the computer running it. Although hard drives frequently come with software to help older computers handle the capacity of the drive, some computers simply cannot keep up with high performance drives. Upgrading to a new computer that includes a new hard drive is sometimes the best solution.

Donna Barron asked:


My friend Sharon called recently to ask for my email address. Her hard drive crashed and she was in the process of rebuilding a new drive–application by application and, it would seem, one email address at a time. Everything on her old drive was gone, including the photos from her recent vacation. Unfortunately, the backups she had been doing so religiously every night contained nothing.

No one really expects a disk crash but drive failures do happen—and often at the most inconvenient times. In addition to the possible loss of important data files, a disk crash can leave you with the daunting task of having to replace the dead drive and reinstall your operating system and all of your applications. While you’re doing this—assuming you know how to do this, your computer remains nonfunctional.

While this “rebuilding” time can range from mildly annoying to extremely aggravating for a home computer user, it can bring a computer-dependent small business, or even a large office, to a virtual standstill. Whatever you use your computer for, having a quick and easy-to-restore backup can eliminate both the distress and the expense of the prolonged downtime normally associated with a hard drive failure.

When you’re restoring from a drive failure, the best kind of backup to have is an image backup. Most backup software products are designed to provide a way to backup and restore individual files. There are, however, some backup software applications that make it possible to backup your entire drive. A complete drive backup is called an image backup or image copy. Some full-featured backup software products will provide both image backup and individual file backup. They allow you to make an exact image copy of your drive and then supplement this with regular (daily, weekly, etc.) file backups. This is useful because, while some files on your hard drive change frequently, many files hardly ever change and need to be updated only rarely if ever at all.

An image copy is a drive to drive copy. In order to create an image copy you must have a second drive to backup or copy to. This can be a second internal drive but it is probably best to use an external drive, such as a USB or FireWire drive as your backup drive. The nice thing about an external backup drive is its portability. You can easily carry it home or lock it up each night. You can remove it and take it with you in case of an imminent disaster, such as a hurricane or flood. The one essential feature of your backup drive is that it must be as large as or larger than your source drive. Your source drive is usually your internal C: drive but it could be any drive you want to backup.

An important issue to consider when transferring an image copy to your backup drive is whether the data will be compressed or encrypted. While compression and encryption are useful tools, they can introduce the possibility of data corruption and this danger is magnified when dealing with such a large data transfer. There are, unfortunately, a great many reported cases of users who, like my friend Sharon, realized too late that their “backups” were nothing more than empty folders or that their backup data was corrupted beyond repair. When choosing any backup software, but particularly an image backup software, be sure that there is a way to verify the contents of the backup to ensure that your backup files contain good, usable, restorable data.

Restoring from an image backup eliminates all the work and time normally associated with rebuilding a new drive. When you restore the image backup to your new drive, not only all of your data files but all of your applications, your preferences, your latest hardware drivers and even your drive partitions are all transferred to your new drive. If you are restoring a boot drive image, the new drive will be bootable as well. The actual time involved in transferring the data to the new drive will depend on the size and speed of the drives.

The only other issue to consider when restoring an image backup is the drive partition size. When you transfer an image of one drive to another, the drive receiving the image will create a partition to contain it. This drive partition will be exactly the size of the old drive. If, for example, you make an image copy of a 120 GB drive on a 200 GB drive, the 200 GB drive will contain a 120 GB active partition and 80 GB of unusable space. If you wish to gain access to the unused 80 GB, you will need to expand the 120 GB partition. This will require a partition expansion utility. Some backup and drive copy software programs include a partition expansion utility.

How do you know if you really need an image backup? Consider how much you value your data, how much time (and money, if you have to pay someone else to do it) it will take to rebuild a new drive if yours fails and how inconvenienced you will be until your computer is up and running again. With external backup drives becoming increasingly affordable, even home computer users can now enjoy the security that drive to drive backup software can provide.

Rg Hannah asked:


One of the best strategies for enhancing data security is the use of a secure flash drive for data that is transported or transmitted. Drives that are not secure will needlessly expose company data to many levels of threat. A decision to continue using inferior drives can lead to the unauthorized access of sensitive and confidential data. These risks to data security can be eliminated by incorporating the use of a secure flash drive like the ones offered by SanDisk Enterprises. Utilizing a secure flash drive is simply one of the most effective methods for enhancing security and safeguarding data.

Improve Security and Control with Secure Flash Drive

A secure flash drive that is independent from the host operating system improves security and control of drives or data. This approach safeguards against unauthorized access by those who would make and attempt to corrupt data. Many times access to the network is used not to steal but to attack against the system and corrupt its data. Reported attacks on host systems have been increasing and inferior drives are at the core of the problem. The use of a secure flash drive can avert an attack on your company data stopping it cold. Improved security and control is accomplished by simply appropriating the use secure flash drives companywide.

When a secure flash drive is lost or stolen it poises no threat to data as central control is able to terminate the drive from further access to the system. Because many thieves are using stolen drives to gain access to host operating systems central control is crucial to an improvement in security. A central control software program allows for the management of a secure flash drive eliminating any threat to sensitive data. Central control is able to monitor or terminate any drive that has been compromised. Operating systems without central control or who are using anything other then a secure flash drive are putting valuable data at risk.

Strength of an Encrypted Secure Flash Drive

Secure flash drive encryption as a standard security precaution increases the strength of security measures and reduces the opportunity for thieves to expose the company to increased liability and risk when data is compromised. Drives that are not using encryption based technology are unnecessarily exposing proprietary data to theft and exploitation. A secure flash drive armed with encryption technology can the prevent compromise of data even if the drive is stolen. The encryption technology used in a secure flash drive is virtually impossible to hack and locks sensitive data down tight.

SanDisk Enterprise offers solutions for companies concerned about security by offering an encrypted secure flash drive for improving the strength of data security. The secure flash drive that features encryption technology is so strong that it can eliminate most security risks to confidential data. A secure flash drive to be considered safe must have encryption code based on a sophisticated algorithm. The sophisticated algorithm will prevent unauthorized access to data during transmission. The drives should be using the AES 256-bit encryption to protect data from security breaches. Encryption will also stop the reading of data should the drive be stolen or the password be broken.

Rg Hannah asked:


With the millions of flash drives in use today a secure flash drive is essential for averting breaches of security. The number of security breaches reported has risen almost 50% and is likely to continue to rise. While the secure flash drive has makes data incredibly mobile it also makes it more vulnerable to loss and theft. If you are using less then secure flash drive you might want to look into SanDisk Enterprise. They produce a secure flash drive that features top of the line security including anti-virus software which drastically reduces the chances of uploading a virus to the operating system via a flash drive.

The Secure Flash Drive under Attack

The use of secure flash drive is necessary to prevent attacks on the valuable data they contain. Security software for flash drives is called anti-malware and can stop data corruption. This anti-virus software when part of a secure flash drive prevents the flash drive from playing host to a virus which then may be uploaded to an operating system. McAfee a global security company provides software for SanDisk Enterprise’s secure flash drive. It scans the flash drive for potential attacks to the host operating system and quarantines them. The software is so effective it removes the threat of attack before it has an opportunity to access the operating system.

The need to utilize a secure flash drive and provide both front end and back end security is a concern if mobile data is to remain intact. Employees that need mobile data need flash drives that are encrypted for security reasons. An adequately secure flash drive will feature the encryption necessary to protect information from being exploited by unauthorized users. A strong front end defense is a strong password authentication process that can work to avert breaches effectively. This in turn allows data to be transferred and stored with confidence. In order to consider it a secure flash drive it must utilize at least an 8-letter combination

password which has been proven unbreakable.

The Secure Flash Drive and Central Control

A secure flash drive to be truly protected against breaches must be controlled from a central control server. Anything less then this places the flash drive at risk. Recently the US Military was forced to put a ban on the use of flash drives because many personnel were not utilizing a secure flash drive. Once the threat was recognized the only way to get control was to place a ban on the use of all flash drives. Without a secure flash drive controlled from a central server the only way to safeguard the operating system is to put a system wide ban on the use of all flash drives. This situation could have easily been avoided with the flash drive system produced by SanDisk Enterprise.

A secure flash drive also eliminates still another threat that exists and that is in the manner in which data is transferred. A solution for the US Military should have been to implement a secure flash drive for their personnel like the ones produced by SanDisk Enterprise. They use the AES 256-bit encryption to protect data from security breaches. Flash drives that receive or store data that is not encrypted during the transfer process as well as after the transfer is complete are vulnerable to a breach. In the event a secure flash drive transmission is intercepted it is going to be useless because the encryption will prevent access to the data contained in the transfer.

Derek Rogers asked:


Solid state drives have been around for many years, but recent technological changes have increased their viability and their popularity. At its simplest, a solid state drive is one that is built entirely out of semi-conductors, rather than a magnetic drive with moving parts. Originally, solid state drives referred to electronics that did not use vacuum tubes, but this definition is now outdated.

One commonly available form of solid state drive is a USB flash drive. These use the same kind of non volatile chip to retain information, even without power. However, these drives have different capacities and form factors from the solid state drives that are now beginning to enter the market.

* A flash drive is designed as an external piece of the computer system.

* A solid state drive is designed to be used inside the computer in place of magnetic hard drives.

On the outside, solid state drives don’t look any different from ordinary hard drives. That allows notebooks and desktop computers to use the solid state drive instead of a regular hard drive. They have the same dimensions as a conventional hard drive and use ATA or SATA interfaces in the same way as the drives we are all familiar with.

So, if these drives look the same and plug into computers the same way, why use them? The lack of moving parts in these drives gives them an advantage over conventional hard drive, which must use drive motors to spin magnetic platters and drive heads. The storage on a solid state drive is instead handled by flash memory, allowing less power to be used, data to be accessed faster and the drive to be more reliable overall.

Using solid state drives in portable computers is made much easier by their lower power use. Since they have no motors to draw power, they use a lot less energy than normal hard drives. While the portable computer industry has taken steps to address this, their solutions still use more power than a solid state drive. It consistently draws less power than either hybrid or traditional hard drives.

Faster data access is possible since the drive platter doesn’t have to spin up and there are no drive heads to move. That allows data to be read from a drive nearly instantly. There’s nearly a twenty percent improvement in the boot time of Windows on a solid state drive versus a standard drive. Reliability is also important. Since conventional hard drives are very fragile, being jarred can damage them. Solid state drives have no moving parts to be damaged, and can be used in computers that are meant to travel in rougher conditions.

Currently, the big reason these drives are not being used more widely, is cost. These drives have been available for a long time, but the cost of the drive would be equivalent to that of the entire computer they were installed in. Since these drives are growing more popular, price is going down, that suggests that solid state drives will soon be more readily available in forms other than USB flash drives.
