Are internal hard drives better than/preferable to external drives or does it matter much anymore?
I need to replace an internal hard drive that went kaput awhile ago but it seems as though stores are pushing external hard drives over internal drives. Should I invest in a internal or external drive as a replacement? I should add that I have a hard drive already that is being used for Windows 7 but I have a big iTunes library which has whittled my drive space down to about 20 GB and need a new drive to store that on while using the internal drive for Windows. Any thoughts? Thanks!

- Cost
- Physical complexity (more wires, extra P/S)
- Speed
A key item for disk life is operating tempature. No all computer cases and enclosures do the same job there.

(593 posts)Having an external drive is nice though because you can move it to different computers and access it easily if your main computer craps out. There are a lot of drives out there that are dual USB/esata. You will need an esata port on your computer though. It is pretty random which computers have the port.

(18,482 posts)...for me that comes down to a number of things.
- is this a laptop or a desktop/tower?
- is your current HDD a SATA type and how big is it?
- and the big question... how much are you willing to spend?
