Pros: -price to performance ratio is insanely good -just as fast as the 970 evo and pro lines and the sn750 but for a fraction of the price -oustanding random 4k iops -buy when when you can because there seems to be a short supply of these -corsair hit the bullseye with these!

Cons: the mp600 line should be coming out soon, and even faster than these. but i couldn't wait to upgrade.

Pros: For a mechanical hard drive the read and write speeds are amazing. I am getting up to 165MB/sec sustained writes on large files on over 30GB worth of files, so it is not a cached write either. Even on small files I was getting up to 95MB/sec writes. On average I was getting 130-135MB/sec writes. I consolidated several smaller drives worth of files to this drive. 1.1TB total data through USB 3.0 adapter on my laptop. You likely would have even faster SATA reads/writes. I don't know how much exactly.

Cons: It wasn't free??? Seriously nothing at all. Great seller, great drive, great transfer speeds.

Overall Review: Using crystaldiskmark my read and write speeds both capped out at 176MB/sec. Not sure if this is the limit of the drive, the SATA to USB 3.0 adapter or the USB 3.0 port on the laptop.

Second time I've gotten hard drives from this seller. Packaging is very securely suspended in the middle of the box with plastic brackets so no matter where on the box a hit was taken the drive would survive. Fast shipping. I have not had any problems with the drives so I have no clue how good their customer service is, but if they pay this much attention to detail on getting the product to you safely and promptly I assume their customer service is fantastic as well.
