what is the difference in 7200.10 and 7200.9 HDD from Seagate?

Other than 7200.10 using perpendicular recording... any other major issues?

7200.10 have 16MB of cache, 7200.9s have 8MB.

Regardless of what technology is used (everybody's all gung-ho on the perpendicular recording buzzword) - uh well the cache doubled too so that might also have something to do with the increase in performance. Anyway, the 7200.10s are faster and they're only slightly more expensive ($15 on the 250GB model). So, like, buy the faster drive. Personally, I think the 320Gb for under $100 is the sweet spot. And I have 2 of them to prove it.

It's all about the cache. 16MB does make a difference.

There were 7200.9 drives with 16mb cache. I have one.

Nobody really knows about the relative reliability, since the 7200.10 is a new design (heads and circuitry, at least).

My 7200.10 250 GB HDD crashed with bad sectors in 2 months...

As Slick5150 noted, there are 7200.9 drives with a 16 MB cache. I too have one: a Segate ST3400633A.
