AS-SSD Incompressible Sequential Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers, while other drives continue to work at roughly the same speed as with compressible data.

Incompressible Sequential Read Performance - AS-SSD

Incompressible read performance is the best we have tested, although I wouldn't get too excited as the differences here are very insignificant. The M5 Pro is only 3% faster than the M3 Pro.

Incompressible Sequential Write Performance - AS-SSD

Incompressible write performance is also great, although Vertex 4 gets to keep its crown. Again, differences are minor when looking at percentages (the M5 Pro is ~5% faster than the M3 Pro).

    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!
