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.
Throwing incompressible data at the controller is another way to get it to shine. With less data that can be thrown away, there's more parallelism to be exploited by the controllers. What results is huge performance - over 2GB/s in the read test and 1.6GB/s in the write test. Note that these scores are more than twice that of the RevoDrive 3 X2 - perhaps due to the use of asynchronous NAND in the RevoDrive 3 X2.

You teased us with your video reviews. Now we cant go back... :-)G-Man - Tuesday, September 27, 2011 - link
I miss the video reviews already :-)vol7ron - Tuesday, September 27, 2011 - link
hahaha. they are a good addition aren't they?Rasterman - Wednesday, September 28, 2011 - link
Comparing a single Vertex 3 240GB to a 1.6TB doesn't seem quite valid. Someone considering the R4 would be asking what is the performance difference between the R4 and 4 to 16 Vertex 3s in RAID 0. Especially considering the massive cost savings per GB using the Vertex 3s.MrBungle123 - Wednesday, September 28, 2011 - link
I'd like to see some RAID 5/6/10 arrays of 15K RPM SCSI drives in the benchmarks too.marraco - Wednesday, September 28, 2011 - link
No. I don't want video reviews, unless they have English subtitles.SilthDraeth - Wednesday, September 28, 2011 - link
I have trouble hearing and use subs for all my movies, yet Anand speaks quite clearly, and I have no trouble understanding him.Also, he posts the video review in conjunction with the written review, and not as a stand alone feature, so you really don't need it subtitled. So you would still get to enjoy the reviews as you always have.

You can write english but not understand it when it's spoken? *shakes head*connor4312 - Thursday, September 29, 2011 - link
I'm guessing you never learned a second language?arthur449 - Wednesday, September 28, 2011 - link
Not all information provided is specifically relevant to everyone's interests in a review of a product. Similarly, information provided in a video review follows a linear arbitrary organizational structure that cannot possibly align with everyone's preferred method of learning. Also, it's easier to skim / search / quote / share a text-based review.
