I just did a quick HD Tune on the drive.
The drive is about 62% full and still a part of my network share(so the numbers may be off a bit).
access 20.6ms (the real reason these are NOT performance drives and instead good for storage.)
CrystalDiskMark does not paint such a nice picture, With a partially full drive it makes sense because it hs to write the files to a slower section.
