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.

Incompressible Sequential Write Performance - AS-SSD

Peak read speed is obviously something the Vertex 3 does very well, while the P3 and 510 fall in second and third places, OCZ has a substantial lead. Now look at what happens when AS-SSD runs a pass of incompressible writes:

Incompressible Sequential Read Performance - AS-SSD

Corsair's P3 is now our leader. What's important to notice here is that Corsair's firmware allows for much higher sequential performance than what Intel outfitted the 510 with, however Intel's drive generally delivers better real world performance as we've seen from our 2011 Storage Bench tests.

    Slightly off topic question: in your review of the Agility 3, you guys mentioned that it's lower power characteristics are due to asynchronous NAND. Does the Agility 2 also use this?

    I want a SSD for a laptop I'm getting within the next 2 months and don't really care as much about performance, just power consumption and bang-for-buck.

    Appears that Agility3 120GB << 240GB with incompressible data (which apparently is typical).

    Would we see yet another big performance drop for 60GB? Need to add this review so we can see what we lose.

    Perhaps the value of SATA III drops precipitously with each halving of SSD capacity?

    This would be helpful to see see "real world performance" in ONE place. For example, Agility 3 60GB, 120GB, 240GB and Vertex 3 120GB, 240GB.

    Incompressible Read Speed: Vertex3 (497) 2.5 times faster than Agility 3 (203)? Is this correct? What accounts for this huge difference?

    Beware the Intel SSD 320 (and probably 510 too).

    Huge number of complete data losses for users.
    Intel finally admits the problem exist.

    To my knowledge noone has been able to retrieve any data.

    Thanks for all of the great lineups here. I'm wondering what you guys think about the Samsung 470 SSD. Also why is the Seagate Momentus XT the only Hybrid drive that I can find out there. It seems like such a good idea. Why haven't any competitors given Hybrids a shot?

    A) Can some one explain to me the different in "8GB span" vs "100% span"?

    B) And how do I compare them?
  • drumm_22 - Wednesday, June 6, 2012 - link

    I have been reading several of the SSD articles on AnAnd and reading reviews on Newegg. I have recently purchased a Sager notebook to use during my college years as an engineering student. I was wondering if an SSD would be worth the money right now or should i wait for SSD's to become more adavanced at cheaper?
