OCZ's Fastest SSD, The IBIS and HSDL Interface Reviewed
by Anand Lal Shimpi on September 29, 2010 12:01 AM ESTNo TRIM, but Garbage Collection
The IBIS drive features a four-controller internal RAID, and there’s currently no way to pass TRIM along to drives in a RAID array, which means its very important to have a resilient controller. OCZ stuck with SandForce and the SF-1200, the most resilient controller on the market today. To make things better however the drive supports idle time garbage collection. With an active NTFS partition on the drive, no IO activity and sufficient free space, the controllers will begin cleaning up the NAND. The effect is profound, below we have a clean drive:
Now, after we've filled the drive and tortured it with random writes:
Note that peak low queue-depth read speed dropped from ~233MB/s down to 120MB/s. Now here’s performance after the drive has been left idle for half an hour:
Remember this is very low queue depth testing so the peak values aren't very high, but it's enough to show the idle garbage collection working.

What PCI device do these IBISes provide? Is it something standard like AHCI that has drivers for every OS, or something proprietary that needs new driver written and integrated into all relevant OS-es?mroos - Friday, November 5, 2010 - link
OK, it looks like the interface to host is SiI 3124. This is widely supported sata HBA and has drivers for most operating systems.But SiI3124 is just SATA host controller - no RAID. So the RAID must be done host side, or sofRAID in other words. It also means Linux should see 4 distinct SSD devices.

Hello,I don't remember if i already posted my question, sorry !
But in installed one IBIS 160GB using the following configurated computer:
ASUS P6T WS Pro (latest BIOS & drivers)
Intel i7 Core 965 Extreme 3.2GHz
Kingston DDR3 1600MHz - 12GB
nVIDIA Quadro FX4800 grphics card
2 Seagate SAS 450GB
Microsoft Windows 7 Pro
After installing Win7 without problems, i installed antivirus BitDefender, several app's (including Adobe package and Microsoft Office Pro), configured Updates NOT AUTOMATIC !
When i stopped my computer, system started downloading 92 Upgrades (without my permission) ?
When i restarted..Crash error 0x80070002
Impossible to restor (i made an image system, but day before !)
Reinstalled, and while i was typing the Key codes for the Microsoft Vision Pro ..
An other crash ! Same problem !
My opinion, about the IBIS HSDL box, it's a very poor assembly design!
Impossible to connec the supply connector on it, and i must dismantle the front plater to have access to the supply connector !
Now, i wonder if i have to follow OCZ's advice about the BIOS configuration?
They are saying:
" You must set you BIOS to use "S1 Sleep Mode" for proper operation.
Using S3 or AUTO may cause instability ".
And what about the internal HDD's ?
Is there any member who already installed such IBIS and use it regularely.
If the answer is Yes (?) can you please tell me how you configured your system ?
Regards,
Paralou

OCZ doesn't have PCIe x16 option like FusionIO ioDrive Octal which takes the reads to 6GB/s
