Performance vs. Transfer Size

ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. Both read and write performance are actually on par with the Extreme Pro, which is impressive. That is explained by nCache 2.0 because ATTO only writes 2GB of data, so the Ultra II has no problem of caching all the writes to its 10GB SLC cache.

    Name one, that competes with mx100 price wise. Reply

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

    I read this
    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. Reply

    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) Reply

    Stay tuned, I'll have an update to share regarding the bug within a couple of days. Reply

    Can't wait :)
    I really wonder whats really up.
  • theuglyman0war - Thursday, September 18, 2014 - link

    really like to hear more from 840 pro users regarding this bug...
    Is it really inherent in the TLC?
  • hojnikb - Thursday, September 18, 2014 - link

    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.
