Here again, it is.
In addition, some high quality SSD devices may have even more intelligent wear leveling algorithms where internal SLC cache has enough smarts to replace data in place that is being re-written during the test if it hits the same address space that is, test file is smaller than total SLC cache. For performance charts on SD cards and other flash media, see for example Tom's Hardware.

Modern operating systems do not normally write files immediately to RAID systems or hard disks. Temporary.
Depending on how the drive is connected you may find that your iodepth was too low. GFXBench is a high-end graphics benchmark that measures mobile and desktop performance with next-gen graphics features across all platforms.
