CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K, and 4K queue depths with accuracy.


Key Features:


* Sequential reads/writes

* Random 4KB/512KB reads/writes

* Text copy

* Change dialog design

* internationalization (i18n)


Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests, since it offers the ability to measure native command queuing at 4 and 32.




By mSATA standards, the 840 EVO mSATA 120GB has solid 4K read delivery. The mSATA version is a little slower than the 2.5" EVO, but in many Ultrabooks, you don't have the option use one or the other. The 120GB model scales well when the queue depth increases.




With nearly 140 MB/s of 4K write at QD1, the 120GB mSATA EVO will keep your random data moving at a fast pace. There isn't a lot of scaling when NCQ stacks up, but in most cases, regular users aren't going to multitask heavily, so it's not that big of an issue. SSDs are already amazingly quick compared to the HDDs they replace.
