Which is faster? Internal HDs or external USB 2 HDs?

It's funny how everybody LOVES to talk about USB 2 vs. Firewire... Do a google search on the topic. There's plenty of information out there... :)

321447 2005-05-17 02:33:00 Grizz77 has a point. USB2.0 is theoretically faster than Firewire, but FW has its own specialities....

Basically, there should be no speed difference (in theory). Here's my PC:
SuperNova root # hdparm -tT /dev/hda /dev/hdb /dev/sda

/dev/hda:
Timing cached reads: 348 MB in 2.02 seconds = 172.05 MB/sec
Timing buffered disk reads: 34 MB in 3.04 seconds = 11.20 MB/sec

/dev/hdb:
Timing cached reads: 364 MB in 2.01 seconds = 180.76 MB/sec
Timing buffered disk reads: 54 MB in 3.08 seconds = 17.52 MB/sec

/dev/sda:
Timing cached reads: 404 MB in 2.01 seconds = 201.33 MB/sec
Timing buffered disk reads: 38 MB in 3.04 seconds = 12.51 MB/sec

Admittedly /dev/sda had a torrent running off it at the time


Chill.
