SSDs do not require defragmentation. Since there are no physical disks, there is no need to organize the data in order to reduce seek time. Therefore defragmenting an SSD is not effective. Also, defragmenting an SSD can put undue wear on specific areas of the drive. SSDs are designed to write data as evenly as possible over the entire drive to reduce undue wear to any one location. Nonetheless defragmenting your SSD drive a couple of times will not harm it. However if it is done continuously over a long period, it may reduce the life of the drive.
Over time, most of the storage locations on an SSD get written to. When they get written to again, they need to be conditioned in order to accept new data. This can cause a delay and is seen as a reduction in drive performance. Garbage collection is a function built into a SSD that reconditions empty storage locations so when new data is written to the drive, there are locations on the SSD ready to accept data.
Although Garbage Collection function is built into most SSD drives, some drives do a better job at it than others. TRIM resolves this issue by letting the operating system tell the drive when to perform this function. At this time, only Windows 7, Server 2008, MacOS 10.7 and newer versions of Linux use TRIM. Also, there are no RAID configurations that support TRIM no matter what operating system is used. All of Kingston’s MLC based SSDNow drives are TRIM compatible. Some of our first generation SSDNow drives are not TRIM compatible.
First, open an Elevated Command Prompt window.
To open an Elevated Command Prompt window: Click on Start Orb > Type "CMD.exe" in Search box > Right click on "CMD" and select "Run as Administrator" (If you receive a prompt confirmation, click YES)
To verify the TRIM command is enabled, type the following and press enter in the Elevated command:
fsutil behavior query disabledeletenotify
The results will be as follows: DisableDeleteNotify = 1 (Windows TRIM commands are disabled) DisableDeleteNotify = 0 (Windows TRIM commands are enabled)
To enable the TRIM command,type the following and press enter in the Elevated command:
fsutil behavior set disabledeletenotify 0
To disable the TRIM command,type the following and press enter in the Elevated command:
fsutil behavior set disabledeletenotify 1
Performance decrease has been reported on some of the SSDNow drives. If you have an older SSD drive that does not have effective Garbage Collection, SSD drive performance will drop over time.This is due to the way the system overwrites data that has been flagged for deletion.
Try using the Secure Erase tool like HDDErase to wipe the drive and restore it to original condition.
We have a firmware update available at the following link for our V200 series SSDs.
We have discovered a technical issue with our SSDNow SV200S3 drives related to intermittent sequential write slowdowns. This firmware update will restore your SSD’s sequential write speed and improve the random read and write performance.
Any of our SSDs can be used in RAID. But due to endurance specifications, only certain part numbers should be used in RAID. For servers, please contact Kingston to determine the best Kingston SSD to use for your workload.
Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) is a built-in monitoring capability in hard drives and SSDs. It can allow users to monitor the health of a device. It does this through monitoring software designed specifically for the S.M.A.R.T. feature. All of our SSDNow drives support S.M.A.R.T.
The Windows Experience Index (WEI) merely measures the relative capability of components. The WEI only runs for a short time and does not measure the interactions of components under a software load, but rather characteristics or your hardware.
Thus the WEI does not measure performance of a system, but merely the relative hardware capabilities when running Windows 7. An article about the WEI can be found here: http://blogs.msdn.com/b/e7/archive/2009/01/19/engineering-the-windows-7-windows-experience-index.aspx
In Vista, the WEI scores ranged from 1.0 to 5.9. In Windows 7, the range has been extended upward to 7.9.
Kingston realizes the importance of keeping our customers’ personal data and information confidential and secure. Kingston takes measures to ensure the security of all of our customers’ personal information when a Solid State Drive (SSD) is returned to our RMA facility for warranty replacement or repair. When an SSD reaches our repair center, it will undergo a thorough testing process. During the first phase of testing, an ATA Secure Erase is performed on the SSD which erases all data and information.ATA Secure Erase is federally-approved by the National Institute of Standards and Technology (NIST 800-88) for legal sanitization of confidential user data. If the SSD is not in a functional state and not capable of undergoing an ATA Secure Erase, the SSD is dismantled and the NAND Flash Memory is destroyed.
ElectroStatic Discharge, ESD is simply the discharge of built up static electricity.ESD should not be taken lightly as this is one of the few things an individual can do to damage or destroy their computer or hardware components.It is like when you rub your feet on the carpet and you touch something metal.ESD can occur without the user feeling a shock and will occur when only working on the inside of the computer or handling hardware.
How to help prevent ESD
The best method of preventing ESD is to use an ESD wrist strap or a grounding mat or table.However, because most users do not have access to these items, we have included the below steps to help reduce the chance of ESD as much as possible.
