Samsung.

Agreed, Samsung are one of the, if not the best SSD manufacturer in terms of Performance and Software tweaking for it. The 850 Evo is no doubt faster than SD900 and well worth the slight fraction higher price. Hope this helps

Are you sure 850 evo is faster? SU900 got 3D MLC which should be faster and have more endurance than TLC?
I know 850 evo is good, but I havent seen any reviews on su900. Its been on retail only few months and the price is close. That is why I am asking.

850 Evo is quick but may not be faster after a sustained workload that saturates the SLC cache. It's fast enough if you are stuck on SATA--you may think differently on NVMe.

The big thing is the reliability--Samsung seems to be the only 3D NAND manufacturer that's got its act together and some of them are downright sketchy.

SU800 because of no SU900 --> http://ssd.userbenchmark.com/Compare/Samsung-850-Evo-250GB-vs-Adata-Ultimate-SU800-256GB/2977vs3912

Apparently the more free space there is the better the Evo performs, and worse when there's less free space, however, the Adata SU800 seems to do better with less storage free? though the Evo triumphs over the SU800 either way and is considerably cheaper. The SU800 is only 20€ less than the SU900 so idk
