Buy 11 750GB Drives and run RAID5. That way you get some sort of assurance.

Buy a 24 port SATA Areca RAID card, get a 1 GB sodimm for the cache (it only comes with 256 MB, and you definately want more).

Then buy 24 500 GB drives, and run a 23 + hot spare RAID 6 array (RAID 6 tolerates TWO disk failures, and the hot spare will kick in as soon as a disk fails, so you don't have any performance hit while you wait for the replacement)

DO NOT buy 750GB / 1TB disks, they are not cost effective.

Please do share w/ us the incredible benchmarks

http://www.newegg.com/Product/Produc...82E16816151004 <-- for PCI-X (Server mobos)

http://www.newegg.com/Product/Produc...82E16816151006 <-- for PCIe (Regular computer mobos)

Btw, let's do a price comparison, let's say you want 7 TB storage

That = 10 750 GB drives, @ $250 each = $2500, no redundancy
OR, get a ton of 320 GB drives ( http://www.newegg.com/Product/Produc...82E16822144188 ) @ $70 each. Get 24 of them, that = $1680, + $1000 RAID card = $2680, but in RAID 6 with 24 drives, you'll have an insane amount of performance and redundancy.

And with the 750 GB drives, you'd probably have to drop a pretty penny on some kind of RAID card anyway, since you won't want to deal w/ 10 seperate drives.

As for connecting the server to the rest of his computers, you will want at least a Gigabit network. Depending on how many computers he wants hooked up, you'll need a Gigabit hub/switch, gigabit NICs if his motherboards don't already have them, and lots of Cat6 cable. For large runs, I suggest buying in bulk OEM and making your own cables. Saves money, and you get the exact length you need. I like yellow, because it shows up easily in attics/crawl spaces.

For that kind of setup, I don't think gigabit is enough.

Gigabit = about 125 MB/s maximum data transfer (Actual is slightly less). He needs to use fiber to get enough throughput to utilize those drives.

Fibre isn't really cost effective in a lot of scenarios though.

This is all covered, house is wired in Belden cat6 and Belden quad shield Coax, his switch is a 10/100/1000 already, and his PC's have 1GB NIC on board. I do not really think bandwidth will be an issue, its mostly for the space. On an bad day 3 PC's in the house might all be streaming movies to each room, most of his movies are going to be ripped from his DVD's, he will only have a small selection of HD movies on this server. And Data loss is a big issue because thats lots of hours of ripping movies. Guy right now has 3 400+3 disc DVD changers that are completly full, so we are talking about getting ride of the changers because he cant add anymore into this setup. And he has his media center PC we build him and he loves it so much he wants it to take over for his hole system. So 3 x 400+3 disc changers trade in for 7TB file server for his movies, and they can access it upstairs. And if there 360 will read the server easy then his son might watch movies off it sometimes. The next problem will be setting up a P:\\ that only him and his wife have access to.

Fiber is not really an option in this setup, we would have to buy 3 x the amount of equipment then we do for just this project. I am thinking we might have to have a custom case made to hold on this Hard Drives. I only wanted to do a raid so that
1) there would only be 1 or 2 or 3 drive letters or folders that we setup
2) DATA loss is a big issue

I like this raid 6 concept, how ever if a drive fails how do we know? You just check on it one day and see the 1 extra on is now running? Thanks for the great info and links! As for HD's he is pretty sold on the WD RE drives with the million hour rating.

SpeedUP, I'm not sure how the card notifies you that a drive failed, but if you email/call the company (areca), I'm sure they can give you some insight. If you find anything out that's useful, do let us know

I'm sure the card gives you SOME kind of notification, these are expensive cards designed for mainly commercial use. There ARE special pins for the fault notification, you may have to buy a small LED panel for just that purpose (and check it once in a while, with RAID 6 you need THREE drives to fail to lose any data, 2 are for redundancy).

2 of our servers at work have both had a hard drive fail in their RAID array but did not notify us in any way. It wasn't till we realised that there were slowdowns on the server that we looked at the RAID.

oh.. well in that case, you'll want to hook up the fault LEDs to the pins on the areca card, and you'll have to check it once in a while.
