The Seagate Backup Plus Desktop STDT5000100 5TB (Regulatory Model: SRD00F2) is a USB 3.0 desktop hard drive found on discount for the Canadian Black Friday sale.

Two of them were purchased for $159.99/each at Futureshop. One performed well, while the other gave a horrible USB 3.0 performance. The problematic drive had a USB 3.0 read speed of ~25 MB/s and write speeds ranging from 2.5-100+ MB/s. Reformatting the drive did not help. As a result, the defective drive was immediately returned and exchanged for a new drive. The new drive, fortunately, worked as expected.

The drive enclosure is made of plastic. The top is glossy, while the sides and bottom are matte. It’s a plain looking black box except for the bottom.

The bottom design is composed of multiple triangular angles in an artistic abstract design. It’s blue and aesthetically ugly. Fortunately, it is not visible when the drive is right-side up. If the design is for improved air ventilation then good; otherwise, it seems odd.

Construction quality is good. The plastic enclosure feels strong and sturdy with minimal flex in the center. However, the corners are sharp enough to cut when scrapped against. Be careful around them and consider dulling them or taping cushions on them. Edges, on the other hand, are not as bad.

Reliability, is already a concern. As noted above, one out of the two hard drives was defective. Fortunately, the defective unit was returned to the store and exchanged for a new one without hassle. However, if that is not an option, these external hard drive come with a 2 year limited warranty from Seagate.

Included with the hard drive was a 47” USB 3.0 cable and a 12v 1.5A AC adapter. Kudos to Seagate for including a longer USB 3.0 cable.

Performance of the working hard drive was excellent. Read speed was around 157 MB/s, and write speed was around 122 MB/s.

For a cheap drive ($0.032 a gigabyte) with fast performance this drive is highly recommended for unimportant data. If reliability is a concern look elsewhere, or purchase two of these hard drives where one is used for back up/mirroring purposes.

Benchmarked below is the Seagate Backup Plus Desktop STDT5000100 5TB (Regulatory Model: SRD00F2) formatted to have a single ext4 partition.
