Re: 1879 vs 1916 disk drive comparison

You have not said how many drives or if you are at the maximum number of
drives supported by the system or the current if any RAID configuration.

We recently installed a pair of 571GB drives into a second ASP
specifically for backups to disk but this ASP could have been to move data
to, thereby reducing disk utilisation in the system ASP

As others have said it depends on the current disk utilisation and the
type of data access / file sizes. 15k drives are significantly faster
than 10k. I remember upgrading a System 38 (I think) to 15k drives and
End Of Month was 50% faster or about 4 hours faster!

We need to upgrade disk drives in our 8202 SAS machine.

We have: 1879: 283GB 15K RPM SAS SFF Disk Drive (IBM i)

Replacement drives: 1916: 571GB 10K RPM SAS SFF Disk Drive (IBM i)

We will will gain necessary disk space but these are 10k drives vs the
1817 at 15k.

What might be the response time for our users?

Thanks,

Jerry
