As hard drive manufacturers push storage densities, offering greater capacities with each new generation of drives, there's more free space for more... stuff. On the desktop, Serial ATA hard drives are pushing the 400GB mark. In the enterprise world, where spindles spin at a minimum of 10,000 RPM, SCSI drives like Hitachi Global Storage Technologies' Ultrastar 10K300 are trickling out in capacities up to 300GB. With seek times as low as 4.3ms and sustained transfer rates up to 89MB/sec, the 10K300 should be no slouch when it comes to performance, either. Read on to see how its performance compares with the SCSI and Serial ATA competition.
The Ultrastar 10K300's 300GB maximum capacity pits it squarely against Maxtor's new Atlas 10K V. Here's how the drive specs compare:
|Ultrastar 10K300||Atlas 10K V|
|Maximum external transfer rate||320MB/sec|
|Maximum sustained transfer rate||89MB/s||89MB/s|
|Average seek time||4.3-4.7ms||4.5-4.9ms|
|Average rotational latency||2.99ms||3ms|
|Available capacities||73, 147, 300GB|
|Idle acoustics||3.4 bels||3.2-3.4 bels|
|Idle power consumption||8-11.2W||7.9-10.8W|
|Mean Time To Failure||1.2 million hours||1.4 million hours|
|Warranty length||Five years|
Interestingly, the Ultrastar 10K300 and Atlas 10K V share the same maximum sustained transfer rate. The Ultrastar has slightly quicker seek times and lower rotational latency than the Atlas 10K V, but it's pretty close. I don't imagine the 10K300's 25-RPM spindle speed advantage will translate into significantly better performance in the real world, either.
Like the Atlas 10K V, the Ultrastar 10K300 is available in 73, 147, and 300GB capacities with 73GB per platter. The drive has 8MB of cache, which is common for SCSI drives, but seems a little spartan considering that the latest crop of desktop Serial ATA drives are sporting 16MB.
Although it's largely matched the Atlas 10K V thus far, the Ultrastar 10K300's 1.2 million hour Mean Time Between Failures (MTBF) rating trails the Maxtor drive by 200,000 hours. However, 1.2 million hours translates to well over 100 years, which goes far beyond the drive's five-year warranty. Five-year warranties are pretty standard in the SCSI world, but with Seagate bumping the warranty period for its desktop drives up to five years, I can't help but wonder if SCSI storage is due for a warranty boost.
Hard drives aren't usually much to look at, but since I know there are undoubtedly some SCSI fetishists out there, here are a few nudies of the drive:
