The following prices were gleaned from fuzzily-rounded newegg figures from different manufacturers (generally products with the highest average rating), not counting technical features and sorted in no particular order:
IDE uATA 133
$0.46 p/GB (80GB)
SATA-150
$0.24 p/GB (250GB)
SATA-150 10,000 RPM Raptor
$2.60 p/GB (36GB)
$2.10 p/GB (74GB)
$1.10 p/GB (150GB)
SATA-300 (32MB cache)
$0.31 p/GB (1TB)
$0.20 p/GB (750GB)
$0.24 p/GB (500GB)
$0.32 p/GB (250GB)
eSATA
$0.48 p/GB (1TB)
$0.29 p/GB (2TB)
$0.30 p/GB (3TB)
$0.42 p/GB (6TB)
eSATA+USB 2.0
$0.25 p/GB (1TB)
$0.26 p/GB (2TB)
Ultra320 SCSI 68-pin 15,000 RPM
$2.30 p/GB (300GB)
Ultra320 SCSI 80-pin 15,000 RPM
$2.06 p/GB (300GB)
Serial Attached SCSI 15,000 RPM
$3.65 p/GB (37GB)
$2.33 p/GB (74GB)
$1.73 p/GB (150GB)
$1.56 p/GB (300GB)
Solid State Disk
$25 p/GB (128GB)
$30 p/GB (64GB)
$15 p/GB (32GB)
Ugly list; didn't want to bother spacing it out in code tags. From what I see, SAS looks like an interesting variation from the same old Raptor setup.
For a few dollars more, you get, 150GB for 150GB:
10krpm (Raptor); 15krpm (SAS)
4.6ms avg. seek (Raptor); 3.3ms avg. seek (SAS)
5.2ms avg. write (Raptor); 3.8ms avg. write (SAS)
2.99ms avg. latency (Raptor); 2ms avg. latency (SAS)
Rant:
Of course, there's still the adaptor issue to take into consideration, which could cost anywhere between $130 to $700 and beyond, depending on how many ports you want, what kind of PCB slots you have available and if it's packed with a rather expensive (~$50ish) SAS cable. On the positive side, SAS drives are a bit more stable around the clock than SATA, faster and who knows, with an update, they might even be able to support this 22,000 RPM that keeps bouncing off my brainpan every now and then on the web. On the negative side, for all we know SAS capability could be lodged in to some motherboard later this year alongside the merry integrated SATA chipset and by the time you're done paying for all the parts now, you might as well have went Ultra320 or bought a second 9800GX2 come March.
