I've owned one of these external hard drives for several years, using it primarily as a backup and archiving device, but also occasionally using it to transfer very large files and directories between computers I own that are too large to put into the cloud or for more traditional forms of transfer media. In that time, this drive has performed acceptably, doing everything that I have asked it to do without any trouble. It has reliably connected to my computer every time I have used it, aaccepted the data that I have transferred to it without any hicups, and stored it without any data errors. The speed of data transfer is about the same as any other USB 2.0 device, so although it can be a bit slow with large amounts of data, it is just as fast as all but the newest external drives. Still, there are a few minor annoyances with this device. When I first got it, the file system was set up for the obsolete FAT32 format instead of the more current NTFS, which was inefficient, limited the size of files that could be put on it, and required me to convert the file system and reformat the drive using Windows utilities. It can also be kind of noisy in operation compared to a lot of devices. However, the biggest annoyance is that it is externally powered, requiring an adapter to be plugged into an outlet, and there isn't always an available outlet close enough to the computer I wish to use the drive with to be used. And of course, being an older drive, it is kind of small by modern standards. Other than those little quirks, it has been a great, not-so-little external hard drive.
