For hard drive:
Very good:
It is connected fast, compact and very quiet in operation. Only the start-up noise after a while the standby is used to. Otherwise, processing is solid and makes a good impression. The heat generation keeps even under load in limits.
Small, self-perceived 'weaknesses':
The USB cable might be a little short (about 1 m).
On-off switch is rear mounted, which might, depending on where the plate is, can be a bit cumbersome.
One or the other is really quite disturbing bright blue light, but you can indeed seal :-)
For files that are larger than 4 GB, the drive must be reformatted to NTFS from FAT course yet.
Bottom line: If it lasts long, a low-cost medium whose purchase price certainly makes itself just in case more than paid off.
