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?

Looks like the seek time for
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) ??

300Mbps = 3Gbps because of the 8B/10B line encoding, to send 8 bits over the wire it is encoded into 10 bits. Same applies to many serial/parallel encodings, gigabit Ethernet has a clockrate of 1.25GHz for example. The max transfer rate isn't that important since the disk is nowhere as fast as the interface speed.
