CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using V5 to test HDD drives.
Our review sample MG08ACA16TE didn’t handle the CrystalDiskMark 4K tests particularly well, in fact it was a little slower than the 8TB version of the Toshiba N300 we’ve reviewed previously, but on the other hand it was faster than the 14TB N300 NAS.
