Crystal Disk Mark

Well, what do you know. I was right... Anyway.

Ah, Crystal Disk Mark. It's a test which often makes drives look very good, hence its widespread use. The test focuses on random read/write performance at a wider variety of pre-determined queue/thread depths. The old version of the software was quite different, but produced very consistent results, hence why it is a favorite. The CDM suite of tests is, it must be said, especially kind to the Seagate drive. We saw 561 MB/s on the sequential read test, and just under the fully advertised 520MB/s of sequential write. On adding some randomness to the mix, performance suffered, but this is as expected.

Some of you might be wondering how the current drive matches up to Samsung's latest QVO SSD? Well, it actually does remarkably well. Granted, it loses out heavily in some of the random tests, whilst keeping the gap much closer during others, as well as very tight when things get sequential. This isn't a shocker, at all, as Samsung's new NAND and in-house controller were always going to be very strong performers. Again, it's difficult to get a read on what exactly the real world performance difference is going to be. However, I would venture that if said real world performance difference really matters to you, you probabaly have enough money in your pocket to be looking at top of the line SATA drives, like the 860 Evo, or even NVMe M.2 SSDs like Crucial's P1, Samsung's 970 Evo, or Western Digital's new 'Black' series.
