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.

Name one, that competes with mx100 price wise.milli - Monday, September 22, 2014 - link

One more confirmation to why the 256GB MX100 felt so sluggish to me during preparation/installation.

I read this http://techreport.com/review/26905/ocz-arc-100-sol...TR compares MX100 with OCZ ARC and comments that ARC is better at the same (or close) price....

MX100 all the time. I do not trust TLC reliability, although Sandisk did a good job on this unit.Notmyusualid - Wednesday, September 17, 2014 - link
I concurr.I have 2x250GB 840 Evo's, and I think they are garbage. Had to beark the RAID0, as they performed so badly.
I then gave one away to my brother.
You won't see me buy TLC nand again in this lifetime.
And by the way, my X25-E is still going strong, without hiccup, as my Linux drive. And how many years is that?

Of course the 840 EVO's perform badly , the old written data bug is kicking in. I wonder how long does it take Samsung to acknowledge the problem and then fix it (if it's fixable at all)Kristian Vättö - Thursday, September 18, 2014 - link
Stay tuned, I'll have an update to share regarding the bug within a couple of days.hojnikb - Thursday, September 18, 2014 - link
Can't wait :)I really wonder whats really up.

really like to hear more from 840 pro users regarding this bug...Is it really inherent in the TLC?

Nobody seems to have issues with MLC drives. There are lots of reports for 840EVO and a few for 840basic.So it must be limited to TLC.
