Guffa.


RAID 0 is where data is saved across several disks. Usually people do raid arrays with 2 HDDs. EX: If I save a .txt file, 1/2 of the actual data will be saved on one disk, and the other half on the other. Then when I load it up, it should ideally load faster because both HDD are putting out data. In more useful applications, think of loading 1 big 1gig file. If 1/2 of the data is stored on each drive, and each drive has a 40megabytes/second sustained transfer, you will theoretically load it twice as fast with a RAID0 array of 2 HDDs.

Now the bad part is there is nothing saved on the other drive in case one of them craps out. ie: right here

That is where Raid 5 comes into play. With 3 drives, A , B, C you get similar performance increase, but you also store the parity data on other drives. So drives B,C will contain parity data of A. If A craps out, then the parity data on B&C can be used to quickly reconstruct drive A. Bad part? More drives, more heat, more money, greater chance for drive to fail (3 * probabaility of failure)

Wtf, at what point would you need to access your data faster? No way people have RAID setup on their home computers. Double-click and shit is right there.

Oh, and I wish that student loans companies had RAID 0 for their setups.

Why have faster pcs? 😕

Why have 600hp cars?

FOR THE SAME REASON.

Its more common in the enthusiast market. Also, it is regularly thought of that RAID=backup. Its not, even 1 or 5.

I think you didn't catch scorpious hint that RAID isn't the best terminology to use for raw striping since there is technically no redundancy. By redundancy I mean practical excess, since the task requires the two drives to work at all.

RAID10 is appropriate in my eyes as the two pairs mirrored disks are redundant before the stripe comes into play

But there isn't any media that requires the combined throughput of multiple drives to play. Even operations like playing 1080P while simultaneously coping data should be no sweat for a single drive.

shh... you're making his vendor nervous.

edit: large file transfers to and fro benefit.

Most people usually use their HTPC for BT, NGs and other intensive stuff.

RAID = Redundant array of independent disks (using multiple hard drives to store data).
RAID 0 = Utter shit. Either hard drive fails, all data on BOTH disks is lost.
IDE = Very old hard drives. Everyone has used SATA for a long time so if you see an IDE drive, chances are the hard drive and all the other hardware involved is at least 3-4 years old.

RAID 0 != shit. I have RAID0 Velociraptors and they are fast (duh).

I back up my OS array weekly to my RAID1 storage array. If you know how to use RAID0, it's fantastic.

How much did you pay for the raptors and what sustained read/write do you get?
 
raid 0 is great if you have a backup plan. who the fuck doesn't anyways. just keep an image on a server and pxe boot if your volume is fubar.

For my home server/HTPC I just bought an 8 port SAS/SATA RAID card. I was looking to do 8x 1 TB Caviar Black drives in Raid 5 (7 TB's useable), but would need to buy 7 more drives. Currently at $90/ea that's $630. I found a guy on the FS/FT forums selling 22 750 gb drives, and will be picking up some of them at $50/ea. That will give me a hair over 5 TB.

Should sever me well for 2 years or so until I bump it to 15 TB's or so.

a lot of people have a flash drive or an external hard drive...but i wouldnt be surprised if most still didnt make regular backups. my mom doesnt, and i keep telling her to, and shed be SOL if her hard drive died today.

Not for a PXE boot - you would need a server. Perhaps you are talking about an Acronis snapshot type solution.

Either way I agree that an external HDD or external storage of some kind is all but a requirement.

I don't recall what I paid but I only bought one of them, I got the other for my birthday.

(X48 onboard RAID, 128k stripe,512mb file, 8mb block size, hdtune file benchmark)
READ: 170mb/s, 7.1ms seek
WRITE: 190mb/s

Finding average speed over entire drive now...
