Pros: This one works! This is an update to my previous review where my SSD was dead within a few days of use. I did the firmware upgrade like the last one and did a full zero out on the drive before use, as recommended by samsung support. So far so good, keeping fingers crossed.

Cons: 1st drive died in 3 days, did not expect that from a samsung product.

Overall Review: Backup everything and clone your original drive if possible before upgrading to this drive. New rating lost an egg due to first drive being dead.

Pros: It's an SSD and functions.

Cons: Kingston went ahead and switched the NAND flash in these units to complete and utter garbage. I am living proof of this as I have purchased at least a dozen of these in the last 2 years. The last 2 I ordered were sluggish. After testing the advertised 450 read / 450 write is an outright lie. Getting 260 read max / 140 write max with crystaldiskmark and other tests on Sata3 port. My old mechanical drives in raid0 were faster than this! The drives used to perform around 500/400 on average before Kingston blatantly swapped the guts of this to relabeled trash. -Slow -Not worth buying -Not worth paying ridiculous shipping cost to ship it back

Overall Review: Shame on you Kingston. Wonder if they will start cutting corners with their RAM now. Oh well I'll officially say Kingston has lost a customer after nearly 20 years of buying their products. Stick with Mushkin, Intel, Crucial, ADATA and save yourselves some heartache.

Pros: Worked great when it worked.

Cons: Dead after 2 months of minimal use. Now if it does power on at all it does not recognize any ps2 or usb devices. Working on an RMA with Intel now.
