[Q]: Raid 0 or Raid 5 for DATA tablespaces : Which is best ?

Hello all Oracle gurus,

May be this question has been already discussed.

I'am in charge of designing a disk layout for a new database.

I need to decide wether I use RAID 0 (stripping) or RAID 5 for the tablespaces containing the data and the indexes.

The database must run 24/24-7/7.

In some books about Oracle, I read that using RAID 5 is not always a good choice for data (possible performance problems during write operations).

In the other hand, in case of a disk crash, a hot plugging RAID 5 system can offer a non-stop recovery mechanism.

Please, let me know your opinion, your experience, ... Any advice welcome.
Thanks.
Sincerely,
Jerome. Received on Mon Aug 11 1997 - 00:00:00 CDT
