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. Read performance scaling is actually better than in the reference design JMF667H we tested, although the SSD340 is still outperformed by the 840 EVO and SP610. Write performance seems to be similar to the reference design and the maximum throughout is definitely a bit disappointing.

    I didn't say "value".

    Besides, $30 32GB SD cards actually hit 45-60MB/s sequential.. Think I saw a $65 64GB PNY rated at 90/60 R/W, doesn't get any more value priced than that, unless you meant bargain bin SD cards...

    Yeah, but sd card like that would be pretty unsuitable for running OS.

    Obviously, their random access speed sucks, he and I were just drawing a parallel to other cheap devices with sequential speeds that aren't very far off... Shoot, I've paid <$50 for 32-64GB USB 3.0 flash drives that hit 200MB/s sequential read/writes. I think any enthusiast knows sequential speed isn't ultimately why you buy a SSD (most of the time), but still...

    I'm pretty sure SSDs from 2009 are faster than this.
  • hojnikb - Monday, August 4, 2014 - link

    they are not.

    2-3 years ago was 2011-2012 :) I have a Samsung 830 128 GB which IRC came out around that time, and it is actually faster, reaching like 380 MB/sec in sequential reads.

    *writes

    Come on AT, what is this - the stone age? You know, the time people wrote on stone tablets and editing was pretty much impossible? How about an "edit" feature?

    I have to say as long as they push 150MBps+ with 0.XX access times most cases are covered.

    All in the access times for day to day usage, not so much the raw MBps.

    its not all about access times.
    You can have a bad ssd with great access times and it will still feel slow as HDD if writes are utter garbage (you can test this by installing OS on a cheap usb drive).
