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.

    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. Reply
