I backed up about 500 GB to my USB 3.0 external drive in less than 1.5
hours. Anyone feel like doing the math on that? :)

That's right in the expected range for USB 2.0. You'll never see the
480mbit/s that USB 2 is rated for--there's a lot of overhead. I've got a
nice new USB 3.0 32GB flash drive that reads at 300MB/s though...

Subject: [H] External USB to internal HDD transfer speeds check
So if you've seen my recent post about my secondary HDD issues you'll know
that I'm transferring a bunch of files from my USB 2.0 external enclosure
(I'm
pretty sure it's 2.0 btw) to my newly installed (and apparently now
working
fine) WD5000BEKT which is a WD SCorpio Black 7200 RPM 2.5" HD, apparently
using SATA I internally based on the dock I have it in...
So I got a rock-solid 28.5 MBytes/sec on my first 16 gigs of data (mp3s)
and
now I'm getting a rock-solid 24.5 MBytes/sec on misc system files I've
backed
up. Multiply those by 8 to get Mbits/sec (if that's even necessary when
talking HD transfer speeds), and it's ~220-200 Mbps or so...
So is that a good transfer speed? What's my bottleneck? Is there any way
to
improve it, or not with my current system and it's innards... I just
figured
there must've been folks here who've looked to tweak/improve that kind of
transfer so I thought I leverage that knowledge! ;)
