Help choosing Laptop internal HDD?

[vijay_001]

Hitachi 1 TB - 5400 RPM, 8 MB buffer cache

vs

Hitachi 1 TB - 7200 RPM, 32 MB buffer cache.

Please suggest which one should I go for?
Does the 32 MB cache make the drive more faster?

you want the 7200 rpm drive it moves the data faster on and off the drive. the cache of a hard drive the larger it is the more data it holds so that the laptop cpu not waiting for it.
