Perfomance difference between stock 5200rpm and Seagate 7200rpm
Just ran Xbench on the 7200rpm Seagate drive (after self-install on a stock MBP 15" SR). Here's the results:
Sequential Access
Uncached Write 4k blocks 47.99 MB/sec now 62.12 (29% faster)
Uncached Write 256k blocks 43.96 now 53.62 (22% faster)
Uncached Read 4k blocks 12.22 now 16.03 (31% faster)
Uncached Read 256k blocks 43.91 now 54.14 (23% faster)
Random Access
Uncached Write 4k blocks 1.15 now 0.81 (30% slower -- surprising!)
Uncached Write 256k blocks 20.56 now 27.3 (33% faster)
Uncached Read 4k blocks 0.43 now 0.63 (47% faster)
Uncached Read 256k blocks 17.14 now 24.04 (40% faster)
So some significant increases in speed, especially in random access -- with the one exception of the uncached 4k random write which actually did worse. Not sure if that's an anomaly or what.
