PCI PCI-E or PCI-X 4 port SATA raid 5 CARD needed that can host 2tb drives? Does anyone know of a cost effective solution??? 500 points!!!

I need large storage subsystem for video recording. need it local to the device.

We want to do a 4 port sata raid 5 with 4 2tb drives. Gives us approx 5.8tb usable.

I chose the promise 150SX4. Well it is limited to 250gb drives. max capacity is 1tb.

So can anyone point out a RAID card with battery backup that is cheap? I cant spend $300 on this card. My target is under $100. That being said I have to bring this solution however I can.

If your host O/S is windows, and it is not an Itanium CPU, then the logical boot disk (c:) is limited to 2.09TB.  You need to get a controller that lets you partition a RAID5 array into 2 logical arrays that it exposes to the BIOS, one being 2.09TB usable, the other partition would hold the remaining approx 3 TB.  I am not aware of any cheap $100 controllers that can do this.

host os is WindowsXP. The OS will NOT site on this system. data volume only.

I would prefer one single 5.8tb drive to appear to the host to make managing vidoes easier.

BTW, my senior engineer asked me to add this.

In 64bit Windows 2003 or windows 2008, using GPT (built in to the os)  you are not limited to 2TB for c drive. I figure you know this b/c you mentioned Itanium. But you can run a quadcore cpu on 2008 and have a boot partition larger than 2TB.

you will need to go to X64 version of XP in order to use a GPT formatted device > 2TB.  I would source a used LSI MegaRAID or 3442-R controller on ebay to get something under $100.

As for your engineer, he/she is close, but in order to BOOT a GPT drive >2TB , you have to be on an itanium.  MSFT just doesn't allow it on 32 or X64 hardware.  So technically the engineer is correct in that the C drive can be formatted, it just won't be bootable.

lol. thanks for being kind. There is so much information available it is hard to know everything for sure. looking up megaraids now.

He did create larger than allowed sets that allowed him to boot when the papers and techs said it couldnt be done. So there is often a way to do things even though it breaks the rules. We are a cost effective shop and have create several unique solutions that shouldnt work, but do. : )

I knew you were aware of this based on your itanium reference.

(P.S. the Dell PERC cards are really OEM versions of LSI cards I mentioned.  so PERC cards are fine, you'll probably find them a little cheaper based on quantity as well. Warning, the older cards do not have firmware that will support > 2TB, and PERC cards are not supported by LSI, so you will have to deal with finding a firmware upgrade on dell site.


LSI cards are safer to use because LSI cards will be supported, and you can download everything you need on LSI support site.

For anyone who comes across needing this, here was our solution.

Highpoint rocketraid 1640 4 port raid controller  $120

http://stores.tomshardware.com/search_techspecs_full.php/masterid=4540159/st=product_tab/

The only 2tb drive on the compatability list was WD2002FYPS RE-4 GP

It is an enterprise class drive designed for SAN systems. They were $285 each.

Total cost for 8TB raw (5.8TB usable) RAID 5 for $1280.

not bad. I will award points to the vocal man who spoke up the most. Thanks!

forgot to mention. what makes the difference is the LBA interface.

32bit LBA 1TB max
48bit LBA 2TB max
64bit LBA  goes to pedibytes!
