Hitachi HTS725032A9A364 vs Seagate ST320LT007 - 9ZV142 : better MTBF & performance
Hitachi HTS725032A9A364 vs Seagate ST320LT007 - 9ZV142
I'm looking at the above two HDDs, the Hitachi HDD comes
with Lenovo X220 while the Seagate HDD comes with Dell
E6230. Both have 7200rpm.
Q1:
Which of the two has better MTBF (as I had a few HDD
crashes before)
Q2:
Which has better IO performance/throughput?
Link below has specs for Hitachi, anyone has the
specs for Seagate?

@ 1ms half-sine pulse (non-operating)
Hitachi is : 1 ms
Seagate : 1.5 ms (track to track seek time)
11ms (average seek time, read)
but for external transfer rate, not sure if the following two refers to same thing:
Hitachi : 300Mbps
Seagate : 3Gbps (I/O data-transfer rate, max) ??
