Samsung 840 500GB SSD Review - Benchmarks - CrystalDiskMark

A number of next-generation SSDs are coming to TweakTown this week. OCZ, Intel and Samsung and others will follow after CES. Today Chris tests Samsung's low-cost 840 with TLC flash in the 500GB capacity size. Does TLC show the love or is this low-cost offering another low-budget blunder?

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.

4K QD1 read performance is 33MB/s on the 840 500GB. The drive scales well to QD4 at 114MB/s. At QD32 the 840 delivers 381MB/s, a rating only rivaled by the OCZ Vertex 4 and Vector (not charted).

The 4K write performance at QD1 was 127MB/s. That scaled to nearly 255MB/s at QD4, but somewhere between QD4 and QD32 the Samsung 840 lost some performance.
