Lots and lots of redo logs

!! Please do not post Off Topic to this List !!

I am planning setting up a new database with the redo logs on RAID 1 array
(mirror).

The amount of space available on the array is 16Gb and only the redo logs will be on there.
The application will generate << 2Gb of redo per day and will be backed up
(cold) each night to tape.

If I set up enough groups (MAXLOGFILES) such that the whole array is full of logs (each probably 50Mb in size) can I safely run this in NOARCHIVELOG mode and still expect ARCHIVELOG mode type complete recovery?

The application will not overwrite a log till several days (and several backups) after it was last used, and the logs are protected by RAID. Recovery requirement is only to be able to get back to the "current state" (say that last 24 hours max.) before failure, not recover way back in time.

Are there any other issues (eg. performance) that I should consider?

Any comments much appreciated.

Thanks
- Bill.
