My only ever experiance od raid was software driven on the motherboard, when I had to reinstall windows I lost everything and vowed never again.

I do have a compaq and a dell sever unit that I picked up but never got round to doing anything with.  The dell has dual Xeon capapility but only has 1 x 933 in it at the mo, but I have a pair of BNIB 733.  This server hass at 300GB of storage over 6 drives  so am considering haveing a play with it when I move.

But I saw the Sata raid card and just wondering whether to try one.

I am open to suggestions and am happy to go to about £100 for one.  I saw those at £70ish

I would only put matched drives together, same theory as I would do with memory.  Same brand /size/speed etc.

Unless you back it up some way, if one disc goes faulty then you lose all your info even if it only has a loose connection (as I once found out ) dropped the drive lost the lot then went on to use a mirror set up but for home use its hardly worth messing with imo just use sata II now  .. :y

If you are using an HP/Compaq server, stick to HP/Compaq's SMART array controller - many of these are battery backed, and thus can have safe write caching enabled.  The OOF server uses a SMART card :)

For Dell, stick to their PERC ones. Not quite as seemless as the HP ones, esp when changing disks, but work well inside Dell's Poweredge stuff.

For desktop PC RAID cards, unless you have specific requirements, the ICH8/9R type RAIDs are 'good enough'.


For RAID to deliver good performance, you need to use SCSI (old) or SAS (newer) disks and controllers though - IDE/SATA RAID will never perform brilliantly.

I just want to play and test Raid setups at first to see what the performance is like.

PC Desktop wise I want to create a central "MyDocuments" wallet on 1 PC to hook every thimg else up to, so I need data reliabilty more than anything whether it be striped of mirrored.  Complete newbie is the best way to decribe where I am starting at.  What ever I did know I have forgotton,

ICH9 type RAID 1 will do what you need, though (like any RAID) if you lose the controller and cannot replace with identical (or backwards compatible) controller, the data is toast.  Also, RAID is no substitute for a proper backup strategy

Agree 100%

Controller card and mirrored drives.  does the same apply to loss of data as you mention above?
