http://www.maximumpc.com/reprints/re...001-08-10.html Buffer size: This is the amount of memory, or cache, that's used to store recently read data, or buffer data, that's being written to the disk. A 2MB buffer is certainly beefier than a 512KB buffer, but diminishing returns actually make the difference inconsequential. You certainly don't want a drive without a buffer, but most people won't see significant performance gains with buffers exceeding 512K. However, super-large buffers do come into play when running servers 1x80G would use less power and give off less heat.

However, if a second drive is desired for keeping two copies of important files in case one drive fails then get two 40s. Otherwise one 80. -- ~misfit~ "chris" wrote in message ... what would the performance advantage of having a HDD with a 8M buffer ?? and would it be better to have 2x 40GIG hdd rather than 1x 80 GIG any comments would be appreciated TIA Chris --- Outgoing mail is certified Virus Free.
