hi there

looking at getting 2 x 500gb sata drives

one was gonna before data

and one for system files

is there any form of raid which would suit this,

the only thing I no about raid is that one of them if the drive fails you cant get anything back,

so laymans terms please

cheers

Yeah RAID0 has no redundancy if one drive goes all data is lost



RAID1 may suit you though -

RAID 1 uses a technology called mirroring or disk shadowing. RAID 1 requires a minimum of two drives that are exactly the same size. Every time a write is executed the same data is written to both drives, i.e. a mirror image. Well, almost a mirror image. The data is not reversed in the same way as when you look in the mirror.

So what you achieve with RAID 1 is data redundancy. If one of the drives fails, the system can continue to run by just writing to one drive. If you have hot swappable drives, you could pull out the bad drive, plug in a new one and the system is back to its normal state. How efficient and easy it is to execute all of this depends onthe RAID controller and/or software that is being used.
 
RAID0 = Striping, so it will be very quick, gives you 500MB storage total, but if one drive goes, you lose the lot.
RAID1= Mirroring, so there will be a tiny performance hit, 500MB storage total, but if one drive goes you should have your data safe on the second drive.

Basically, if data safety is your priority, use RAID1.

1 gig actually, using the 2x500GB drives mentioned in the first post.
