After a few days of use, I'm pretty satisfied with this external drive. Warning the effective capacity of 500 465go not. Think also to format it to NTFS from the start if you want to store files larger than 4GB. Save before preinstalled software. About noise, frankly fairly quiet in operation. No additional noise read / write. Design side, fingerprints and scratches inevitable. The small blue LED in the center comes alive during a transfer. Finally, if you plan to carry it, consider taking a bag, pasque is fragile and scratched. In short a good product for the price;)
