RAID5 with my Perc 5i flashed to the LSI firmware with 3x1.5TB drives I benched 189.4 MB/sec in HD Tune on average in sequential with write through (caching) turned on. Reading was actually the slow side of things with only 3 drives, only 81MB/sec. It's ~300MB/sec now in reads with 5x drives.

Naw homes - 5 drives of 2TB or 4 of 3TB - it's either 8 or 9 TB of storage....... I think I will be good ^_^.

worse comes to worse I can get 2x 4 Port LSI's and do two arrays

Here's an ATTO style test (with IOmeter) of 8 x 2.0TB Samsung HD203WI (5400RPM) drives in RAID-6:

I'd say they're plenty fast for a media server.

Well, RAID-5 with 3 drives is only going to give you 2 times the read/write performance of a single drive, so your write numbers makes sense. Not sure why the read numbers were so low.

The other advantage of the PERC cards is that they're CHEEEEEEAP. My 5i with battery backup unit and ram was $130 shipped a few years ago. I think the 6i's can be had even cheaper now. An 8 port 3ware card is going to be $500+

I have a PCI-X hardware-based RAID with battery backed write cache sitting in my closet. I thin it's a 3ware or SIG. I thought I could use it in a PCI slot but the manuf included a tab that prevents PCI-X backwards compatibility. This means you MUST have a full PCI-X slot.

If someone can use it please give me a PM with your name, phone#, address, and paypal address and I'll PIF it to you for the cost of shipping from 90017
