Sequential Read/Write Speed
To measure sequential performance I ran a 1 minute long 128KB sequential test over the entire span of the drive at a queue depth of 1. The results reported are in average MB/s over the entire test length. These results are going to be the best indicator of large file copy performance.
Again we see that low queue depth transfers don't stress the Z-Drive enough to flex its muscles.
Sequential Performance vs. Transfer Size (ATTO)
I stopped putting these charts in our reviews (although I do include the data in Bench) because they are generally difficult to read. Here we're only going to look at three drives though: a Vertex 3, RevoDrive 3 X2 and the Z-Drive R4 CM88:
Now we're starting to see something. If you can't scale with queue depth, scaling up the transfer size seems to do the trick. After about 64KB the Z-Drive R4 starts to pull away fro the RevoDrive 3 X2, peaking at just over 2.5GB/s!
Read performance is even more impressive: the Z-Drive R4 manages just under 3GB/s for 2MB transfer sizes.

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.
