OCZ's Fastest SSD, The IBIS and HSDL Interface Reviewed
by Anand Lal Shimpi on September 29, 2010 12:01 AM ESTPCMark Vantage & SYSMark 2007 Performance
With four SF-1200 controllers in RAID, the IBIS performs well as a desktop drive but honestly most desktop workloads just can’t stress it. In our PCMark Vantage test for example, overall performance went up 10% while drive performance went up 30%. Respectable gains, but not what you’d expect from RAIDing four SF-1200s together.
The fact of the matter is that most desktop workloads never see a queue depth (number of IO requests that must be fulfilled) higher than 5, with the average being in the 1 - 3 range even for heavy multitaskers. It’s part of the reason we focus on low queue depths in our desktop iometer tests. The IBIS isn’t targeted at desktop users however so we need to provide something a bit more stressful.

If this innovation will eventually make it's way down to personal computer, it could simplify board design by allowing us to do away with the ever-changing SATA standard. A PCI Bus for all drives, and so much bandwidth than any bus-level bottleneck would be a thing of the past. One Bus to rule them all!LancerVI - Wednesday, September 29, 2010 - link
One bus to rule them all! That's a great point. One can hope. That would be great!AstroGuardian - Wednesday, September 29, 2010 - link
I want AT to how me how long will it take to install Windows 7 from a fast USB stick, install all the biggest and IO hungry apps. Then i want to see how long will it take to start them all @ the same time having been put in the Start-up folder. Then i want to see how well would work 5 virtual machines doing some synthetic benchmarks (each one @ the same time) under windows 7.Than i will have a clear view of how fast these SSD monsters are.

Well aren't you demanding... =pPerisphetic - Thursday, September 30, 2010 - link
...or the past.Well it's probably deja vu, sounds like it.
This is exactly what the MCA (Micro Channel architecture) bus did.back in the day. My IBM PS/2 35 SX's hard drive connected directly to this bus which was also the way the plug in cards connected...

"Even our upcoming server upgrade uses no less than fifty two SSDs across our entire network, and we’re small beans in the grand scheme of things."That's why the prices of SSD stay so high. The demand on the server market is way to high. Manufacturers do not need to fight for the mainstream consumer.

I hate to feed trolls but this one is so easy to refute...The uptake of SSDs in the enterprise ultimately makes them cheaper/faster for consumers. If demand increases so does production. Also enterprise users buy different drives, the tech from those fancy beasts typically ends up in consumer products.
The analogy is that big car manufacturers have race teams for bleeding edge tech. If Anand bought a bunch of track ready Ferraris it wouldn't make your Toyota Yaris more expensive.
Flash production will ramp up to meet demand. Econ 101.

Except that there is a limited supply of NAND Flash supply is limited while the demand for Ferraris does affect the demand for Yarises. Further, advances in technologies does not have anything to do with the shortage for Flash. Still further, supply for flash is very inelastic due to the high cost of entry and possibly limited supply of raw materials (read silicon).p.s. Do yourself a favor, do not teach me economics.

Sorry for the bump, but in my original massage I simply expressed my supprise. I was not aware of the fact that SSD are so widely available/used in the commercial side.Ushio01 - Wednesday, September 29, 2010 - link
I believe the random write and read graphs have been mixed up.
