Having just seen: http://www.eetimes.com/story/OEG20000223S0007 I'm curious to know if they'll be appearing in NetApp's soon.
I'm also curious to know if anyone has any more information to share regarding the effects on filer performance of the number of spindles, the number of chains, the size of the disks, etc, etc, etc. Everyone went a little quiet last time this came up.

The article doesn't say, but bigger, faster disk drives often draw more power. Thus, NetApp needs to have shelves that can support them first, before they can test them for reliability. There are a lot of issues involving mechanical vibration and so on that have to be assessed before such a drive could be qualified. It may be that this particular drive is not appropriate for certain shelves.

More spindles is better performance, if you are read-heavy. If your filer seems slow and it's reading constantly but the CPU is still under 100%, more spindles could help.
