Given the drives that Sun shipped in early Ultra 10s I'm not surprised.

I find that IDEs are generally pretty good. The high end IDEs have
similar bit densities to high end SCSI so transfer data at a similar
rate when the spindle speeds are comparable. Most of the high end
IDEs are available in 7,200rpm versions so they will be slower than
their 10k rpm SCSI counterparts. I find the thing that lets the
IDE drives down is when you are doing simultaneous read/write. They
read fast, they write fast but don't ask them to do both at the same
One thing to note is that the IDE controllers in Suns aren't that
great. We get better performance off the same IDE drive in a modern
PC than in an Ultra 5/10. I don't know whether the Blade 100 has
a better IDE controller than the ancient U5/10 one.
2 drives on a controller isn't so much of a problem when so many
people do multi-controller cards. You can also get some really
nice IDE->SCSI RAID systems. These usually have a controller
channel per pair of drives and hardware raid control interfaced
to a SCSI channel on the back. That way you get the best of
both worlds and you end up putting the Inexpensive back into
