External drive usb2 / usb3

[fpefpe]

Hello --- it seems that most new small laptop don't have an optical drive, so picking one seems to be a challenge in itself ---- I think I read someplace that  the  connection, usb2  or usb3  does not make a difference,  since it the drive itself that will dictate the speed --- so in  looking for a drive does it matter if its usb2 or usb3?  Thanks

The speed of the connection can and will limit the speed of the drive. A fast bd drive won’t work properly over a usb 2 connection.

I doubt you could buy a recent model that doesn’t have the correct connection type required to achieve what the drive is capable of. Therefore, you probably don’t need to worry too much.

thx for the  info --- I just a  portable that is usb2 --- there is so many to pick from --- would info on the drive  itself reveal it actual speed?

Somewhere in the product listing you should see the various read and write speeds for the different media types supported by the drive.

Are you after a dvd drive or a bd drive?

I guess a  blu-ray  writer would be best --- would it make sense to get a drive that would be installed in a desktop and mount in an enclosers?
