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

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.

I agree, also it would be cheaper. 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.
