I have been reading about and am intrigued by SAS (Serial Attached SCSI) as far as speed goes.
http://en.wikipedia.org/wiki/Serial_Attached_SCSI
The drives are relatively small in capacity but spin at either 10,000 RPMs or 15,000 RPMs.
This might require an actual benchmark test, but which is faster: a Zero Striped Array or an SAS drive?
The cards that offer RAID ability and SAS ability are expensive -- $600-$800!
I'm thinking of getting a, say 300GB SAS drive, and keeping only my operating system on it (Mac OS X on the next release of a new Mac Pro -- which I now understand may be delayed as it is tied up in court over a suit between Intel and nVIDIA over "Nehalem").
Everything else I'll keep on another drive.
I understand the operating system uses free disk space for a (I don't know the correct terminology -- "scratch disk"?)
But if I have 8GB RAM wouldn't the entire operating system load into RAM leaving nothing unread on the hard drive?
What then does the OS use free hard drive space for?
Any help is appreciated,
defender
