Hard disk is still faster at sustained read, than flash. but flash has much faster access time. this means that for large files flash is slower. according to http://en.wikipedia.org/wiki/ReadyBoost for typical speed values the the critical size is about 20KB. (starting a large program in linux can involve reading many small files) for best performance one would need to decide where things were cached based on this. also you need to keep the cache filled with useful information. preload is a daemon that aims to do this. from what i have read about ReadyBoost, it handles hot plugging of the flash drive, and just falls back to read to disk. if you have application memory swaped out to a flash disk on linux and it disappears then then i am pretty sure bad things would happen. sam -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
