What customers say about "Key Specs"

Samsung 850 EVO 500GB 2.5 inch Solid State Drive

Install was easy and the write/read speed were very close to advertised speed.
It has read speeds of around 540 Mbps and will greatly improve you system speed. I have had users ask me what I done to their computers because it is so fast now.
The drive has great read and write speeds. The drive also fits within the drive bay as it should.
Reading/writing speed increased considerably for all my programs. I highly recommend.
This really gave my old PC a boost as far as speed and storage capacity.

What customers say about "Features"

Samsung 850 EVO 500GB 2.5 inch Solid State Drive

Uses normal SATA III interface and was recognized by computer with no problem.
If your system supports SATA 3 only, you won't be disappointed with this; I personally bought a few, and never had an issue with any of them.
Very fast SSD and offers 256-bit encryption, I cannot find a better SSD than this one.
The 32-layer 3D VNAND flash memory ensures reliable performance, and AES 256-bit encryption keeps my data private.
No reduction in start-up time. Still takes about 20-ish seconds. Not bad, but I don't understand why there isn't at least a little improvement.
