Does a hdd's cache size affect its speed and performance? :o 

Just wondering the difference between a 500gb 32mb cache hdd and a 500gb 16mb cache hdd!

More about : hdd cache

one with 32mb cache will perform better than one with 16mb cache!

As with anything that depends on multiple things for its performance it makes up a part of it. All things being equal a drive with more cache will be slightly faster, but only when dealing with a full cache. The more cache a drive has, the more it can load what you think you'll need next, and the more it can send you at SATA speeds before it empties.

Its important to note that all things are not equal. A drive with a larger cache probably has other improvements as well such as higher aerial density and other improvements. This means your better off with the 32mb drive, probably.

^^ When the cache is bigger, it takes up more room, in effect squeezing the air inside the drive, so the result is higher aerial density. My goodness, it is plain as the nose on you face. :) 

Now don't everyone get all sideways here, just a little Thursday morning humor..........
