techie help needed for raid media server

Ive been running a media server at home with WHS2003 on an old Dell PC, with approx 3TB in drives - all USB other than the system drive. Internally its IDE. It was in need of a speed boost and storage upgrade!

I've just bought 4 x 2TB drives (SATA), which I was going to buy an adeptec 2610SA 6 port PCI SATA(II) adapter to use with, but I now have a nasty feeling it doesnt support 2TB drives.

I'd rather not buy a new system to house the drives, but looks like it might be the case.

So... anyone know if they do tsake 2TB drives and if they can happily take 4 of them running raid 5?

No off topic trolls please.

I don't know the answer, and I'm kinda struggling to see the benefit of the idea, too. A 2TB drive on its own is enough to saturate a Gbit ethernet connection, and even a full BluRay stream is only going to occupy about 40mbps of that after headers, so unless you're streaming multiple BluRay to a fairly large network, I don't see how RAID would be of much benefit. I know there's the reliability factor, but even that's just a trade-off againt other aspects of reliability. Adding complexity just means more points of failure and more work if it does go wrong.

By the way, SATA cables go up to 1m and if you use a bit of wire to connect the green and the black connectors of an ATX PSU, you can have an always-on dedicated power supply for the harddrives. Couple of the tricks I used to use for my old, and now disbanded farm of harddrives.

The benefit is that I have lots of media to store on the drives! And the benefit of Raid 5 is parity. If one drive dies, I can easily replace and not lose a bit of the 8TB of data!

Network does play a part in this upgrade, though its not got anything to do with SATA drives really.

Is it not this one Adaptec Serial ATA RAID 21610SA (edit this is 16 port though :lol)

you got link to the 2160SA as the 2160 is a discontinued product. XD-084 is the 2610SA but Adaptec seem to not want to list it

Not sure what you're looking at!

This is one on ebay 140415894397

As you suspected you are right "kind of"

The maximum RAID size you can create natively with that card is 2TB, however there is a workaround

This card will apparently do the job though

Jeez...this is the cheapest on that page and comes in at over £500! I think I'll pass on those!

Damn.... I'm kinda stuck with this now!


4 x 2TB drives sitting spare unable to be used. The PCI cards I was looking at wont support a Raid 5 array with this size drives...

I'm now thinkiong about building a new PC for a server, that will support these 4 drives and raid, something for the OS as well (ie not part of those 4 drives) and a Gigabit network card.... Any pointers?
