hi all
looking to set up a raid 5 setup.
have:
2 x 320gb Samsung F1's
1x 1t Samsung F1
just wondering will i have access to my 1t drive as normal using raid 5 ?
if not what will the setup look like on my pc, (1 640gb drive ect)?

thanks
 
Your array will usually be 640GB in size. You will be wasting a lot of storage on the 1TB.
Some systems can work around this and do a raid5 ish array differently.

With those disks you'd be better doing Raid0 on the 320GB's and using the 1TB as a normal backup drive.
That's what I'd do anyway. I'm sure other people will chip in.

A few questions..

What's the performance difference when using an onboard RAID chip as opposed to a dedicated RAID card?

If he's RAID 5'ing two 320Gb drives, would a 640Gb F1 be the best choice as the third drive, as that wouldn't waste any space surely?

If he does get a disk failure, to recover the data does he remove all the disks from the RAID and plug the 640 say back straight into his mobo? Would that boot?

dedicated raid cards (decent ones) have a processor onboard to calculate the parity for writes to the volume in a raid 5/6/10 etc setup which increases write speed dramatically over onboard solutions.

in a parity setup like raid 5 setup you can only use the size of the smallest drive available for all drives, so in this scenario each drive will use 320MB .... that's a lot of wasted space on the 1TB and even a 640MB will only get half of it's total space used.

drives taken off the array and plugged directly into the mobo cannot be read - the data is written across all drives.
 
You can't RAID 5 two drives, you need another 320gb F1 drive at least.

If you want to build an array with your current drives, set up RAID 0 on your 320gb and backup onto your 1tb.
 
You can make a 320gb partition on the 1tb drive and raid 5 the three 320gb volumes, using the rest of the 1tb disk as a separete, non raid partition.

I don't recommend this over raid 0 + backup, but it does work if your heart is set on raid 5
 
cool thanks a lot guys, got another question then
looks like i will go with raid 0 in the end seen as im a 3d modeller and have massive files everywhere.
just wondering is there any decent programs that anyone’s used to automatically back up everything to my 1t?
don’t want to end up using something crap that don’t work lol
thanks so far
 
If you using Vista its got a built in proggy.
Otherwise manually backup your data files.
Sofware solution? I used drive copy one click program for its easy usability.
And it was only £25.

If these files are your livelyhood, think about making a second backup and storing it offsite.
 
thanks im using windows 7 at the mo, so i guess i'll look into that.
yeah i have a offsite backup drive but it would be cool to have something just to hand


bit of a update just given away my f1 1t to my bro and now im looking to get another drive. dont have to be another 1t. just wondering whats the samsung f1 RIAD drive about?
thanks

Normal drives can cause issues sometimes in RAID. It's all to do with unreadable data. A normal drive will retry to read the data before giving up, but a raid controller normally gives up a lot quicker. This can cause the raid to sometimes drop the disk out of the array as it's still trying to read the data the controller thinks it's offline.

"RAID" disks usually give up a lot quicker by design limiting this problem.
Also RAIDs are "usually" used in systems where they are utilised a lot harder than normal systems so some "RAID" drives can handle the constant use a little better then regular desktop drives.

If this means much in real terms for the way that most of us guys use the kit...I'm not 100% convinced.
