SanDisk Ultra II (240GB) SSD Review
by Kristian Vättö on September 16, 2014 2:00 PM ESTAnandTech Storage Bench 2013
Our Storage Bench 2013 focuses on worst-case multitasking and IO consistency. Similar to our earlier Storage Benches, the test is still application trace based – we record all IO requests made to a test system and play them back on the drive we are testing and run statistical analysis on the drive's responses. There are 49.8 million IO operations in total with 1583.0GB of reads and 875.6GB of writes. I'm not including the full description of the test for better readability, so make sure to read our Storage Bench 2013 introduction for the full details.

| Application Development | Compile projects, check out code, download code samples | Visual Studio 2012 |
We are reporting two primary metrics with the Destroyer: average data rate in MB/s and average service time in microseconds. The former gives you an idea of the throughput of the drive during the time that it was running the test workload. This can be a very good indication of overall performance. What average data rate doesn't do a good job of is taking into account response time of very bursty (read: high queue depth) IO. By reporting average service time we heavily weigh latency for queued IOs. You'll note that this is a metric we have been reporting in our enterprise benchmarks for a while now. With the client tests maturing, the time was right for a little convergence.
As the Ultra II is not geared towards heavy write workloads, its performance in our 2013 Storage Bench does not come as a surprise. However, it is one of the better value drives as it beats the MX100 by almost a 50% margin and is only slightly slower than the 500GB 840 EVO (unfortunately, I do not have the results for the 250GB EVO).

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.
