Solid State Drives
The technology behind SSDs is also known as flash memory. It’s becoming more mainstream as prices continue to drop and more organizations are beginning to adopt it in their daily operations. Some of the major benefits that organization are taking into considering in the adoption of SSDs include performance, durability, form factor, and efficiency. In terms of performance, SSDs have much better speed. An operating system that resides on a traditional HDD can take one minute or longer to boot. Compare that to fifteen seconds on a SSD. When it comes to running applications, handling large workloads or working with complex data sets, again flash storage devices can handle those tasks more quickly. Flash storage or SSDs are more durable than its counterpart. This is because they have no moving internal parts. HDDs rely on spinning disks. In the event of a disaster, data is retained and is secure. Whereas if a HDD crashed, there is very little chance of successfully recovering the data from it. Form factor is important because SSDs can be used in both laptop and desktop computers. The standard size for an SSD is 2.5 inches. For desktop computers, there’s no need of changing out the motherboard because SSDs use the standard SATA port found on nearly all of today’s motherboards. SSDs are very efficient. This stems from they use less resources than competing storage systems, they consume less power which in means reduced energy cost and less expenditure of funds toward energy costs (Delgado, 2014). Major Disadvantages and Possible Hazards before Adopting SSDs. The first disadvantage of adopting flash technology is cost. SSD’s are still relatively expensive. For example, the cost of a 1 terabyte internal drive is roughly $75. A 1 terabyte SSD cost $600. That’s eight times the cost and many organizations are staying away from the technology because of it.
Another disadvantage is storage capacity. Although I mentioned a 1 terabyte SSD, they’re somewhat rare. Typically you’ll find SSD’s sized from 128 to 512 gigabytes. These lower sized drives aren’t sufficient for organizations or individual users who store photos, music, and video content locally. Therefore, the lack of storage space, and lack of availability make the traditional HDDs more attractive as they are certainly more plentiful (Domingo, 2014). Recommendation or not for consideration of SSDs. The Delaware Health and Social Services is running a risk of pushing its existing system to the limit because of health care legislation. It would be better for this government agency to proceed with upgrading to SSD drives in place of the 15,000 rpm drives. The agency is involved in a great deal more of SQL databases and the use of an SSD offers significance performance over traditional drives. As for the Disabled American Veterans nonprofit organization, they’re already using the technology on a smaller and have a very good sense of how it can benefit the organization. They should continually monitor the cost of flash technology and if it continues to fall in price, they should consider getting a preapproved budget so it will already be in place by the time their next upgrade is due. Both organizations clearly see the benefit of the newer technology, but cost is a factor. However, the benefits should be taken into consideration and in time the initial cost can be recouped because there will be no need to upgrade as quickly due to the reliability and durability of flash memory technology. Computer Forensic Examination of SSDs. SSD technology certainly has made the job of forensic personnel more difficult. This is because of two fatal flaws. The first, is repeated write operations which causes the flash memory chip to wear out over...
