The new Seagate Backup Plus Portable comes in 4 or 5TB – it
is part of a larger range of Seagate Backup external hard disks and SSDs.
The Seagate Backup Plus Portable has the highest capacity of
any external SATA 6/USB-3.0, 2.5-inch hard disk yet. The 4 and 5TB models come
with a black, silver, light blue, gold or red textured polished aluminium finish.
Its Seagate’s way of ensuring you get maximum bang for buck.
Review: Seagate Backup Plus Portable
Size: 115.3 x 80 x 20.9mm x 265g
Capacity: 4 or 5TB (smaller capacities come in
Well built, nice Red, textured aluminium cover plate over a plastic chassis and that’s it.
We tested this on a Lenovo 219 Yoga C930 (our reference device)
USB-A 3.0 port and ran the same tests and USB-C 3.1 port.
The SATA 6 interface maxes out at 6Gbps (750MBps) and the USB-C
interface at 5Gbps (635MBps). But the reality is that no external hard disk can
come close to these limits as the interface needs to support both read and
write at the same time.
In our Crystal DiskMark test, it achieves 141.9/129.6MBps sequential
read/write, which is pretty much the same as other major brands achieve.
Where the antiquated USB interface and 5400RPM hard disk
speed shows is in random read and writes of larger files. It slows right down –
but again, that is the same, if not better than competitors.
Predictably the USB 2.0 480MBps transfer speeds were abysmal
(as they are on any brand) getting just over 30MBps sequential read/write.
We used a USB-C to USB-A adaptor and tried it on a USB-C 3.1 gen 1 (5Mbps), but the results did not make sense – they were slower again, probably due to the adaptor. You could get a USB-C 3.0 cable to micro-B you should get the same speeds as USB-A 3.0.
Note: Video recording/streaming and still photo editing use
No USB-C 3.0 hard disk device can achieve sequential read/writes
USB-C 3.0 SSD can achieve read/write of up to 500Mbps.
4K video recording requires about 11Gbps (1375MBps) – this drive
is not for that.
4K Netflix style compressed streaming requires about 25Mbps (or 3.125MBps). This drive can stream defragmented 4K video. But the nature of hard disks is that data laid down randomly and you need it sequentially. Yes, you can defrag the disk (a lengthy process).
For any disk intensive use look at Thunderbolt 3 or USB-C connected SSD.
GadgetGuy’s take: Seagate Backup Plus is low-cost backup at speeds as good as you will get
At 5 cents per GB, it is a low-cost way of storage and backup.
It is a shame that this hard disk technology has reached the limits of speed.
The added value of the bundled software will be in the eyes
of the beholder. The added value of the Seagate Rescue goes without saying.
We recently reviewed the excellent, nay almost perfect, Seagate
Fast SSD USB-C storage and it blows external hard disks out of the water
speed-wise but at around $650 (33 cents per GB and a maximum of 2TB it’s just
not economical to spend the equivalent of $750 for 5TB!

As good performance as you can get from a SATA 6/USB-3.0 interface, 5400 RPM external drive
Seagate value added software
If file transfer rates are important consider external SSD
