USB 2.0 Hard Drive Not Recommended Yet. And Testing C:
By fastest963 | October 1st, 2007 | 4:15 pm
A USB 2.0 Hard Drive is not recommended for use as a boost device!
I have 4 portable hard drives (ranging from 160gb to 250gb and 3 are Seagate and 1 is A Western Digital). All of them had cache increase speeds of .75 to .94, with around 80% cache built (after 1 hour)!
That was with 2gb allocation! I will repost speeds with 1.5gb and 1gb.
So I suggest not using them as your device, at least at this point.
Instead, I’m testing the speed with C:\ (main WD drive)(1256mb allocated) and a SanDisk 1gb Cruzer (512mb allocated).
I wonder if using C:\ is a bad decision?, so I’m testing it. I also have PF enabled on C:\
I will reply with speeds once I get some more testing in…

First of All I would like to point out that custom HD images do not show up in the control panel.
Secondly there should be a better way of showing the progress of the build cache.
Popup
Message Box
Third, after an amount of time and viewing of folders, the drives have the sharing hand on them in the control panel and they are not being shared. (completed building icon???)
Lastly, the scores (after 100% file size in cache) (scores are ones posted with built in speed check with iTunes running):
Cruzer (512mb Allocated): 1.45
Cruzer (512mb of 1gb Allocated) & Seagate 160gb external USB (1536mb of 28gb Partition allocated): .975
– note: The HD did not finish building cache (well it stopped building but the files in cache was not 100%) (it was about 70%-75%)
Cruzer (512mb of 1gb Allocated) & WD 160gb internal (1gb of 160gb Allocated (C:\)): .65
Cruzer (750mb of 1gb Allocated): .76 (don’t know why)
Computer Stats:
Ram: 1gb
Processor: Pentium D 2.8ghz
Internal HD: 160gb WD WD1600
iTunes: 7.4.3.1
OS: Windows MCE 2005 (latest updates)
Video: ATi X1600 Pro (512mb) (overclocked using AtiTool)
I will post more scores as they come in.
Hopefully some better scores :D

Latest Test:
SanDisk (564mb of 1gb Allocated): 1.74
– It looks like between 50% and 75% of disk space available is best for running and not portable hard drives.
