Enterprise Storage Bench - Microsoft SQL WeeklyMaintenance
Our final enterprise storage bench test once again comes from our own internal databases. We're looking at the stats DB again however this time we're running a trace of our Weekly Maintenance procedure. This procedure runs a consistency check on the 30GB database followed by a rebuild index on all tables to eliminate fragmentation. As its name implies, we run this procedure weekly against our stats DB.
The read:write ratio here remains around 3:1 but we're dealing with far more operations: approximately 1.8M reads and 1M writes. Average queue depth is up to 5.43.
We don't see perfect scaling going from 4 to 8 controllers but the performance gains are tangible: +42% over the RevoDrive 3 X2 and nearly 3x the performance of a single Vertex 3.
Average service time continues to be where the Z-Drive R4 really dominates. The use of 8 controllers in parallel appears to be able to significantly reduce average service times when queue depths skyrocket. The R4 CM88 is now over two orders of magnitude (136x) faster than a single Vertex 3—and 227x faster than the Intel X25-E. Again we see that the RevoDrive 3 X2 is much slower than it should be here, possibly pointing at a firmware bug or some other enhancement on the Z-Drive R4.

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.
