I just made the acquisition of this disc that is fast as well in writing than in reading. As such, and at this price I am totally satisfied with my purchase.
By cons, Usb cord is poor because after 2 connections the drive was no longer recognized.
Fortunately I had another cord Verbatim one who has given everything its function to LaCie drive.
A good product with an accessory m .... it's a shame for the image of the brand!
