SATA RAID5 Spare/replacement disk same type and size?

Hello all,

We have a PowerEdge 1800 server with a SATA RAID5 disk setup on CERC5.1 controller.
We are looking for a spare / replacement disk in case one of the disks fails.

Do we need the exact same drive? Or a drive with the same capacity?

Disks in the RAID5 are 3 x Maxtor 6Y160M0
These disks are available through Dell.

Locally available are 6L160M0 Maxtor disks. Can we use these as spare/replacements disks?

The 6Y disks are SATA DiamondMaxPlus 9
The 6L disks are SATA DiamondMax 10
Both are SATA 1, 160 GB.

Thanks in advance,
Richard.

    You'll need the exact same drive in order to either add it to the array or make it a hot swap spare. Trying to add something different the controller won't recognize the disk as being available for use on the array when you try to add it.
