Help Choosing Hard Drives + Raid(s)

post #1 of 6
Thread Starter 
ok so here's the thing. I have 580Gb of storage on my pc at the moment, and fast running out of space. I have 2x250Gb samsung spin points partitioned:

disk 1: C for windows, D for Programs
disk 2: E for my Music, Movies, and Photos

disk 3 is an old 80Gb Pata drive that i put in there to have ubuntu on, i use grub to boot between the 2.

Soon i will be purchasing a Media Streamer and placing the ''zones'' all around my house. The sonos would stream the music from my pc to the receivers in the rest of the home. This will be used by the rest of my family and i don't want their music leaking into my library on my pc (when im in an os listening to it), so i would buy a new drive and rip all our CDs to there. I would rip them in flac at a low compression (6 on a scale of 1-8, 8 being the largest file).

Could anyone recommend a large hard drive, or possibly 2 to put them in raid (i would buy a pci raid card)? We have around 250CDs and i don't want to have to rip them all again in the case of a hardware failure. I don't think they have to be fast if they are just streaming music so i would have them configured as raid 1 because music doesn't require that much bandwidth across the network. I was looking at getting around the 1TB mark because we are constantly buying more CDs and ripping them.

Another raid/storage related question: i will be building a new pc for my parents business soon. They only use it for accounts/stock lists/customer databases and so on. It would probobly have a low end core2 processor and 2 monitors (cheap 8 series card). The main concern here is storage and reliability. Because we are not spending the money elsewhere i think it is important to have raid (dedicated card again) but this time possibly 5 or 0+1 because to loose the customer database would cripple the business. At the moment it is kept in a relatively poor database (ive seen it) at one of the shops.

My question is: how much storage would i need? Do databases take up alot of space like music or less? This computer will also be backed up regularly to a NAT that is in the house for safety but i still think raid is important. I don't think i will need as much storage on this machine because there will be no media, or hardly any, i was thinking around 500gb, maybe 4 X 200 in raid 5 (or 0+1).

Thanks, Boyd

For your house I highly recommend using Western Digital RE2s. They are the absolute best performers I've seen under multi-user loads. You really won't need a seperate card though, your onboard controller should be able to handle it fine enough. I'm guessing each CD is gonna take up about 500MB, which means you need 125gigs to store 250 of them. I don't know how much space you want to buy, but go ahead and get two drives for a RAID1. Onboard RAID5 is extremely slow, and since you don't need TBs of space it'll just be a waste for you.

For your parents its really hard to say how much space theyd need without knowing the size of their business. Databases can take up anywhre from like 50mb to 500petabytes. But one decision is easy - get a seperate controller card and a battery backup for it, and make absolutely sure its 100% hardware based. The software based motherboard RAID is much more prone to data corruption since it uses your computers RAM and processor to do everything. Also, if your parents ever switch computers you can just move the entire RAID over - something you can't be sure you can do with onboard RAID. For a budget card I really recommend the Areca ARC-1220. It costs like $400 and the battery module for it is like $100, and it is the best performing card you will get without paying corporate prices.

Thanks alot Manyak. I quite like the look of 2 . 320Gb Caviar RE2s in raid 1 for the price:GB ratio. i don't think we will ever exceed 320 Gb worth of music.

I have had software based raid (raid 0) fail of me in the past, it wasn't good. But £320 for the Areca ARC-1220 is a bit much to spend , i will be making regular backups onto a NAS and DVDs less often so i think i will go with a cheaper option, with maybe 4 ports like the ARC-1210 which is £163. But do you know if i can still buy a battery pack for it? I think raid 1 with regular backups (daily at least) would be enough.

Yup the 1210 supports the same battery pack (the model is ARC-6120) as the 1220.

If you are gonna stick with the 1210, just keep in mind that it has extremely bad performance in RAID5 setups, but if you are just going to use RAID1 then yeah its perfect

yep ill just be sticking to raid 1, as i don't think they would need/notice the performance boost of raid 1, and if it is poor on the card then it's a definite no-no.

yep, found the battery pack on Scan and it says its compatible. Everything seems to be coming together nicely now.
