I was reading a story where Seagate were talking about 60TB disk drives. That’s all well and good, but how quick can I get data to and from them? If I need a certain number of spindles to get the performance I require, then I’m just going to end up with masses of wasted capacity.
I can picture the scene now. I have a database of “x” terabytes in size and I need “y” number of spindles to get the performance I require, so I end up having to buy disks amounting to “z” petabytes of space to meet my performance needs. Not only is it hard to justify, but you know the “spare” capacity will get used to store stuff that’s got nothing to do with my database.
Just think of those 60TB bad-boys in a RAID5 configuration. Shudder.
