Re: Bottlenecks

Rod Speed pravi:
They are for some ops like imaging and copying and editing large files.

Yes, but few people do such things on their computers.

Mindless silly stuff. Plenty image their systems and plenty
do basic editing of video files, most obviously with PVRs.

Yes, honestly, almost every PC user out there uses his PC to view and copy around video files. They are much bigger than the average file and any improvements in disk data access speed have clearly visible effects.

My Linux computer has 512 MB RAM and Linux uses nearly all of it's free memory for disk cache. I use free disk space on my Linux computer to store movies and CD backups and in copying them back and forth, the amount of cache Linux uses greatly improves performance (speed at which files are downloaded from one computer and stored onto another) compared to a pair of windows systems, where each uses only a fixed amount of 80 MB cache (+ 8 MB hardware disk cache).

A RAID0 array running on one of my Windows machines, with no additional cache (other than 8+8 MB of hardware disk cache) also visibly improves the performance, especially when transferring data: the array <-> LAN or the array <-> RAM.
