No real issues. Just plugged it in and started loading from a portable DVD drive. Seems fast but since the machine is a firewall/router drive speed doesn't seem to matter too much. Size is much more than needed, probably could have gotten by with a smaller drive.

I purchased this to replace the failing hard drive in my iPod classic. Yes i'm an old man in music terms. This was used in conjunction with a small circuit board that attaches to the connectors already in the iPod. Works great and has upped the capacity of my iPod.

Got this for my X220 to add an additional boot drive to install Mac OSX. So far it's been working well and I have no complaints.
