Ease of Use

I installed this as my C: drive, and it indeed sped up my boot time. Nice! PC started to crash every 30 minutes or so after about 6 weeks of daily use. Tried to use another PC to do a disk clone to try to save it before it died. While trying to copy the disk, this Sandisk SDD began to fail after 20 min, then 10 min, then 5 min, then wasn't recognized at all ever. Each time I restarted the clone after disconnecting and reconnecting the drive which again worked for a shorter time each time, -- wasn't able to get it all. Very disappointed in the disk. Tried the warranty page on Sandisk site, but got kind of a odd response. Will try again when TG holidays are over. Had to focus on getting a new drive and re-installing Windows and all programs etc. to get moving again first.

Complaints against some SSDs have included system freezes or crashes (usually blamed on the software controller made by LSI-Sandforce), or that most SSDs lose performance when they are over 25% full. Our Sandisk Extreme 240GB is 8 months old and 48% full. When tested (using ATTO/CrystalDiskMark/AS SSD) , the results are very close to when the drive was brand new with Windows 7 freshly installed. And the system has not crashed once during all that time. It seems Sandisk engineers worked hard to get the bugs out of their software before releasing this SSD onto the market. Small files make up the bulk of what we do on computers and this Sandisk model also reads and writes small files very fast, even compared to many models that came out more recently. I would say Sandisk is one of the top reliable SSD brands along with Intel, Crucial, and Samsung. You pays your money and you takes your choice. One thing you should do with any SSD after installing Windows 7 or 8 (or after cloning an existing Win 7 or 8) is to run (or re-run) the Windows Performance Assessment. This set of tests alerts Windows that you are using an SSD and Windows will make important adjustments such as turning off Defragmenting and Pre-fetching which are not needed with an SSD. But, BEFORE you install or clone Windows 7 or 8 on the SSD, be sure to go into the computer's BIOS setup screen and change the hard drive SATA Mode to AHCI (or Enhanced on some PCs). This will allow the SSD to work at its fastest.

Very Nice the best

Opening comments: I have owned pc's for 25years. THIS IS ABSOLUTELY THE BEST BANG FOR THE BUCK UPGRADE YOU COULD EVER HOPE TO BUY!!!! IT IS EVEN BETTER THAN REPLACING A 2YR OLD COMPUTER OR LAPTOP AND OF COURSE CHEAPER!! Other benefits: windows is more stable. If you have a lot of programs open at the same time, the computer remains stable all day. Now, I rarely need to reboot.
