Pros: Price

Cons: Reliability

Overall Review: Used to replace drive in Dell D630. System crashed again within 2 days. Diags showed too many bad sectors. RMA'd for replacement. Replacement drive crashed within 6 weeks. These drives are made by Seagate, now. Not so sure that's a good thing.

Pros: Fast and reasonably priced... IF they work.

Cons: Bought 2 of these and apparently they are quite picky when it comes to chipset/SATA Controller. If you have an AMD chipset or are running these off of a Marvell HBC... good luck. Whether these SSDs are configured in a RAID array or not, you're going to have trouble. Samsung blames the chipsets/controller. Funny because EVERY other brand SSD works just fine in this environment. So far, Newegg is refusing to do anything other than an exchange for identical drives. Of course, since it is an issue with ALL 850 EVO drives, this will do me no good whatsoever. Looks like I'll just be out $400+

Pros: It did not bite me and give me rabies when I pulled from packaging. It's a lovely green color.

Cons: Ordered 5 of these for a SOHO client Gigabit upgrade (10 of their 15 systems were already Gigabit capable). 4 systems were constantly disconnecting/reconnecting. Finding it hard to believe I'd have 4 out of 5 cards with problems, I RMAd the ProSafe Gigabit switch. Well, I was wrong. New switch arrived and these systems still had the same issue... which is made even worse if you force these cards back down to 100Mb. If it was a single card, I'd chalk it up to luck of the draw. 4 out of 5 cards all having the same issue??? Well, that means they are junk. Due to RMA turnaround on the switch (which was pretty fast... thanks for that, Newegg!) and weather issues preventing the swap, I'm now outside of the 30-day Newegg RMA period and possibly stuck with these POSs.

Overall Review: Stay away.
