SanDisk Ultra II (240GB) SSD Review
by Kristian Vättö on September 16, 2014 2:00 PM ESTAnandTech Storage Bench 2011
Back in 2011 (which seems like so long ago now!), we introduced our AnandTech Storage Bench, a suite of benchmarks that took traces of real OS/application usage and played them back in a repeatable manner. The MOASB, officially called AnandTech Storage Bench 2011 – Heavy Workload, mainly focuses on peak IO performance and basic garbage collection routines. There is a lot of downloading and application installing that happens during the course of this test. Our thinking was that it's during application installs, file copies, downloading and multitasking with all of this that you can really notice performance differences between drives. The full description of the Heavy test can be found here, while the Light workload details are here.
The 2011 Heavy Storage Bench is a bit of a letdown. SanDisk has never really excelled in peak performance like Samsung has and even with nCache 2.0 the Ultra II is not as fast as e.g. the MX100 and 840 EVO. In the Light suite, which is more relevant for typical client users, the differences are far more marginal and practically negligible in the real world.

considering a RAID with one of the value SSD offerings. Would be nice if these reviews included RAID considerations in these reviews. ( does the SLC n-cache, or the MPR parity effect RAID perhaps? [158Gbit of usable capacity:132 of final user capacity does this effect RAID in ANY way?] )And how about a shootout between the mx100 evo 840 and ultra II in RAID configurations.
As many seem to go on about how final user experience is fine with these value SSDs I would imagine that at RAID speeds that would be doubly true? And the savings more meaningful?

I always saw your reviews well. Thank you.But I have a question about your TRIM Validation test.
If I want know about my SSDs Trim Performance then I only just follow your method?
What are difference "MS WHCK's Trim Performance test" and your test.
And I want know how working about the "WHSK's Trim Performance Test Workload"
Do you know that? or How can I trace (or see, or known) the "WHCK Trim Perormance Test Workload"?
Thank you.

Is TLC nand even a good idea considering what is happening to the 840 EVO and older data?I'm worried about TLC nand loosing data if it is powered off for a long time.

Excellent alternative to the MX100. I'll grab a Sandisk rather than a Crucial for my next build.
