Performance vs. Transfer Size

All of our IOmeter sequential tests happen at a queue depth of 1, which is indicative of a light desktop workload. It isn't too far fetched to see much higher queue depths on the desktop. The performance of these SSDs also greatly varies based on the size of the transfer. For this next test we turn to ATTO and run a sequential write over a 2GB span of LBAs at a queue depth of 4 and varying the size of the transfers.

Sequential read performance is marginally faster compared to M3 Pro and overall excellent at all transfer sizes.

Sequential write speed is also slightly better than what the M3 Pro offers, although performance between IO sizes of 4KB and 64KB could be a bit better.

    Was looking forward to this drive beating the Vertex 4 but not only does it not do that, it also costs a ridiculous amount...

    I'd call it a win if Plextor does better with less DOA units and better customer support. Every OCZ I've bought has required a firmware update, which are hard to do at best to start with. And I've just had too many OCZ failed drives. Sometimes second place is better, and in this case it might very well be so.

    Amen to that, brother. OCZ drives are released in an alpha/beta state, and their support is simply atrocious. I'd far rather pay a little more and deal with a reputable company than go through the nightmare that is 'working' with OCZ.

    Plextor, unlike OCZ, does have a 5 year warranty...

    actually, all Vertex 4's have 5 year warranty too

    I would agree if they were close to the same price. Plextor is better but not for nearly 2x the price.

    Kind of depends on how much your time is worth. If you have a lot of downtime due to the SSD crapping out, the Plextor might be well worth it.

    That's another reason why nVidia wins over amd gpu's.

    piss off troll

    :) ... he probably didn't get that "piss off troll" translates to "over the past years several large EU retailers have released reliability reports and AMD, in the graphics department, did some of the most reliable cards, Nv... not so much. Cudos to AMD's partners! RIP BFG!
