Importance of hdd cache?

Slightly better, yes, and the ones with 32 MB caches just a little better again. The differences are in the time to locate a file and feed its data to you. If you don't need speed you probably can tolerate the difference easily. A larger cache is really a help at working with access to long sequential files, but less help when your application has to jump all over the disk looking for new small files. Gamers love big caches, fast HDD rotational speeds, RAID0 arrays - anything that gives a tiny margin of improved performance. Many everyday users find these small improvements hard to notice.

I used a 8MB to install a game demo stored on the drive. I think the demo was either call of duty 4 or unreal tournament 3 or both and it took forever compared to a 16MB. Never used a 32MB but sounds fast. Try to experiment with those mentioned demos and get out your stop watch. Otherwise if you keep your drive defragmented it doesn't really effect actual in game performance.

Buffer size makes virtually no difference that you will be able to see. If you are looking for a fast reasonably priced drive either get a black or 12

more than buffer size you want a drive with a high data density

since drives can only read one side of one platter at a time.. a drive with 500GB/platter is alot faster than one with 250/GB/platter.

something like a seagate 7200.12 500GB can be had for about 50$ if you watch for a sale.

its a 1 platter drive with 16MB buffer
