I have an old desktop PC with a 250 MB hard drive. I would like to
increase the storage capacity and think 500 MB may be enough.
The new drive will replace the old one.
I notice that 500 MB is a size which I can now buy in 2.5 inch
format. Is a 2.5 inch drive likely to be better (faster, lower
power consumption, etc) than a 3.5 inch drive? Are the connectors
the same?
Or would it be better to install another 3.5 inch drive?
Thank you for any advice.
A 2.5" drive will be marginally lower power than a corresponding 3.5"
drive. It is also likely to be lower speed, but not so that you
would notice much. It will cost more per MB than a 3.5" drive - but
you are talking about such low capacity (for modern drives) that this
will not make much difference either. So it is not going to make a
huge difference either way.
(I assume you mean GB, not MB, in your sizes. A 500 MB disk would be
hard to find outside of a museum.)
Firstly are we talking SATA or PATA drives? SATA have a flat data
cable about a centimetre wide whereas PATA are 5 to 6 centimetres
wide.
In my experience 2.5inch drives are noticeably slower than 3.5 inch
drives when I've run them on the same motherboard.
If you are SATA have you thought about an SSD? They can be much
faster.
The drive woul dneed to be SATA. Sorry, I forgot to mention it.
No!!!! My mistake. I mean PATA. The old one with the 40 or 80 way
connector.
