[AusNOG] Server/HD Question

[Chris Ricks]

Two little things:

1. I think we all mean 7.2K drives - 7.5K drives are quite hard to get,
as they don't exist. :-)
2. There are 2 types of 7.2K drives - nearline SAS and SATA. There's
very little to split these in terms of performance, but depending on the
server they're being shoved into, a nearline SAS device may have better
connectivity to the backplane (and shouldn't require a pesky interposer).

Regards,

Chris
