Hey all, I'm looking to buy some external storage which I will probably use for audio sample libraries, so I want it to be pretty speedy. How much of a difference will buffer size (2mb vs. 8mb) make for accessing audio files in complex directories? The drives I'm looking at are a Western Digital 250GB 8MB cache for around $250, and the LaCie FW800 Big Disk 320GB 2MB cache for around $350. Will having FW800 more than make up for a smaller cache? What are people's experiences with different cache sizes? (Interestingly, all the LaCie drives only seem to have 2mb caches except the 500GB big disk, and I've always pretty much understood them to be very desireable drives). Thanks!
