Two of the traces are sequential accesses, while two are 4K rando accesses. Real-world performance testing is done with our custom test suite involving robocopy bencharks and PCMark 8's storage bench.ĬrystalDiskMark uses four different access traces for reads and writes over a configurable region size. CrystalDiskMark is used for a quick performance overview. We’ll revisit then.Our evaluation routine for hard-drive based direct-attached storage devices borrows heavily from the testing methodology for flash-based direct-attached storage devices.

Seagate informed me midway through the review that there will be an updated version of the Backup Plus Hub in a couple of months. What you lose, obviously, is a bit of portability. With either product, you get a lot of storage for your dollar, and at least with the Hub, better performance than with 2.5-inch drives.

Though Seagate’s Expansion series is a bit cheaper, I found the Backup Plus Hub’s USB ports super-handy. Then again, we all did just that back in the day, and some still do. Just don’t try to run an operating system off of it, and you’ll be fine. In total, the Backup Plus Hub is fine for backup, and great for storing large files as well as streaming movies. Doubling them up in RAID or rotating them are also options. Note: Hard drives fail, so you should never use a solo drive as the sole repository for your irreplaceable stuff. Use single hard drives for backup, scratch space, or for storing easily replaceable data-anything that can be downloaded again or easily recreated. The X6 is capable of twice that with 10Gbps USB, but 400-450MBps is easily fast enough for small everyday SSD transfers. I benchmarked a Crucial X6 using the Backup Plus Hub’s ports and saw just over 400MBps writing and 450MBps reading. Of course, the USB ports, being 5Gbps, are capable of much faster transfers. The Seagate Backup Plus Hub easily bested the 2.5-inch competition. In our real-world 48GB copies, the Backup Plus Hub proved equally dominant, shaving nearly six minutes total off the times of the 2.5-inch drives compared here. IDGģ.5-inch hard drives not only offer more capacity than 2.5-inch hard drives these days, they also offer better sustained performance. Note that performance will likely vary a bit with the larger and smaller capacities (a little faster or slower, respectively).īeing a hard drive, small file and seek performance (17 to 25 milliseconds) is slow-abysmal by SSD standards. The CDM 6 numbers, shown below, were a tad slower, but still indicative of the advantage that modern, denser 3.5-inch hard drives have over 2.5-inch hard drives. The 8TB Backup Plus Hub managed nearly 190MBps sustained reading and 150MBps sustained writing under CrystalDiskMark 7 32GB tests. That’s not surprising given that we’ve seen several internal 3.5-inch hard drives top the 250MBps mark. Given the limits of USB and hard drive technology, the Backup Plus Hub performed significantly faster than all of the 2.5-inch units we’ve tested. That series includes SSDs, 2.5-inch hard drives, and 3.5-inch high-capacity hard drives.

If you don’t need the USB ports, you can get 16TB for the same US$330 that the top Backup Plus Hub sports, with Seagate’s Expansion series. That's better than the warranty for some of Seagate’s cheaper external hard drives, which are warrantied for only a single year. The warranty on the Backup Plus Hub is a good two years.

Seagate’s Toolkit software offers both traditional file backup and folder syncing.

Note that the drive comes preformatted with NTFS-you’ll want to change that to exFAT if you’re a Mac user. It will do the job if Windows File Backup or macOS Time Machine aren’t of interest to you.

Toolkit is attractive and competent, supports pure backup and folder syncing, and works on both PC and macOS. It wouldn’t be a Backup Plus if it didn’t include Seagate’s own Toolkit utility/backup software. Seagate’s Backup Plus Hub has a power jack and female USB Micro-B connector gracing its backside. On the back of the enclosure are the AC adapter jack and a Micro-B USB port. When I first opened the box, I was half-expecting charge-only functionality, but you can plug in anything you want to the USB port, including additional storage devices. Seagate rightly figures that if you’re going to have something large on your desk that requires a power cord, you might as well put the extra juice to work. The reason this particular Backup Plus model includes 'Hub' in its moniker is that it sports fully functional dual USB Type-A ports on the front. No, it’s not going to fit in your pocket. Sporting a 3.5-inch hard drive and an AC adapter, the Backup Plus Hub is hefty, weighing about three pounds and measuring around 4.75 by 7.75 by 1.5 inches.
