Samsung 850 Pro 512GB Full Review - NAND Goes 3D!
PCPer File Copy Test
Our custom PCPer-FC test does some fairly simple file creation and copy routines in order to test the storage system for speed. The script creates a set of files of varying sizes, times the creation process, then copies the same files to another partition on the same hard drive and times the copy process as well. There are four file patterns that we used to try and find any strong or weak points in the hardware: 10 files @ 1000 MB each, 100 files @ 100 MB each, 500 files @ 10 MB each and 1000 files at 1 MB each.
I've restructured these charts to group by test as opposed to by SSD. It should make readability and comparisons a bit easier. Feedback is welcome here.
Margins are slim here, as most of these SSDs are nearly pegging SATA 6Gb/sec throughput. That said, the 850 PRO is the fastest in nearly all of these.
