CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
* 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.
The Samsung 840 PRO 512GB nearly surpassed the 40MB/s mark in 4K QD1 reads, but the 840 EVO on its own tops 45MB/s. With RAPID Mode enabled, that number goes up to 80MB/s on the first run. When you run CDM again, the 4K QD1 result surpasses 100MB/s. We're actually not running any of the tests today with back-to-back runs, so the DRAM cache portion isn't pulling 100% hot data.
On its own the 840 EVO 750GB is like a larger 840 PRO. Once you turn on the tier 0 cache in Magician, it's kind of like jumping through time and bringing back an SSD from the future.
