Since then (all using an eSATA drive off the HP 6157; Vista SP1 and using ReadyBoost) I found file types that copy much faster. A 23 GB folder of MPEG video files (.m2ts files)copied at 48.6MB/s -- by far the fastest copy of large folders I have seen. Also, a 2.6GB folder of mp3 audio files copied at ~ 32MB/s using the same setup. A correction/update to my May 16th copy speed information.

Used Lenovo T61 laptop, HP 6157 PC [both 2GHz Core 2 Duo with 2GB ram] and various combos of 8GBSD card, Fujitsu USB pocket harddrive and a WesternDigital MyBook 500GB external drive using 3 interfaces: eSATA, USB 2.0 and Firewire. Results were mixed. Generally the SP1 copies were faster. 20% to 81% faster than RTM in most of the cases. There were strange unexplained exceptions at times to which interface was fastest, etc. The eSATA was often the fastest as expected but NOT always. Best speed seen under any combination was 23MB/sec. By far the majority of cases were much slower -- in the 5 or 6MB/sec range. Smaller folders tended to copy at faster MB/s rates than did larger folders. Complex folders (e.g. 18,000 mixed Office files in 700 folders) copied much slower rate wise than did "simple" folders with few subfolders and fairly uniform file sizes (like 397 jpeg files that totalled ~400MB.) I have yet to see any logic to any of these empirical results. I have heard obscure theories but nothing logical. I've seen credible claims by reliable Sr. users who say they get 20 to 30MB/sec file copy rates using Win XP and 2 harddrives on the same machine using ATA interfaces. I do not get anywhere near those speeds. I recently ran tests [with Vista Home Prem RTM and then with SP1] using several folders of files ranging from 183MB to 3.34GB.

There is a noticable drop in performance on each one. The only up side was that System file checker now actually works and finishes its scan. There is a lot more CPU usage going on in the background that wasn't there before and startup & shut down is a lot slower. I do not understand what has been fixed with SP1 because all of our PC's ran better without it.
