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.

Plextor M3 does well in incompressible sequential speeds as well. Its incompressible sequential read speed is average in our chart, but the difference between most SATA 6Gbps SSDs is only a few percent—nobody is significantly faster here. Incompressible sequential write speed is the best we've seen on a Marvell based SSD, but the Samsung SSD 830 and OCZ Octane retain their crowns.

    ". Not the end user, not even their good reputation"

    Er . . .

    No concern for the end user, or even their good reputation:

    Kristian, Thanks for the clarification. One further question, in the Intel 520 review, the performance of Sandforce based SSD after TRIM cannot recover to clean state. Isn't this something of concern? The M3 can recovery its clean state performance either via GC or TRIM but this is not possible with Sandforce based SSD. Would this count as one strength on M3's Truespeed implementation?

    It's mentioned that the Razor Blade had a Lite-On SSD. Lite-on and Philips "owns" the Plextor-brandname when it comes to this types of products - under the PLDS-name - see /www.pldsnet.com. The Lite-On SSDs are the same as the Plextor SSDs. So it's more that Plextor is a high-end marketing-name for Lite-On?

    Plextors M3P should be reviewed. Great SSD. Fastest of the Marvell-based SSD it seems...
