Seagate Backup Plus Ultra Touch Portable HDD Review: Secured in Style

In our testing, we're pitting the Seagate Backup Plus Ultra Touch against a variety of external SSDs and HDDs that use Thunderbolt 3 and various USB interfaces. Closest to the Seagate is the LaCie Mobile Drive (LaCie is a brand owned by Seagate), which is a pricey metal-clad 5400RPM external HDD and also included are results against the LaCie 4TB Rugged RAID Pro, which utilizes two 2.5” HDDs in RAID 0. Next, we’ve taken out the 1TB SanDisk Extreme Portable SSD and 480GB Kingston HyperX Savage EXO, both much pricier SATA-based solid-state drives. As well, we included a 1TB G-Technology G-Drive Mobile Pro for some Thunderbolt 3-based competition to stir things up a bit. There's no way the trio of hard drives is going to compete with the collection of SSDs, but it's always good to have comparison numbers to show why people opt for solid-state storage, aside from the increased ruggedness that comes from a lack of any moving parts.

Transfer Rates – DiskBench

DiskBench is a storage benchmarking tool that allows us to test the transfer or copy performance of a storage device with real data. We test external drives with three file transfers that consist of 25GB of photos (10GB of iPhone jpgs and 15GB of RAW photos from a Canon 6D), 50GB of movies, and 25GB of documents. First, we transfer each folder from a 1TB NVMe SSD to the external device; then we follow up by reading a 3.7GB 7-zip file and a 15GB movie back from the device.

Alongside the LaCie Mobile Drive, the Seagate Backup Plus Ultra Touch lands at the bottom when transferring files. During the Photo and Documents transfers, the Seagate drive hit ~100MBps and peaked at 122MBps during the Movie transfer. Read performance also ranks it last or second-to-last. With an average read speed of 120MB/s, its rather sluggish compared to our flash-based competitors.

Trace Testing – PCMark 8 Storage Test 2.0

PCMark 8 is a trace-based benchmark that uses Microsoft Office, Adobe Creative Suite, World of Warcraft, and Battlefield 3 to measure the performance of storage devices in real-world scenarios.

Seagate’s Backup Plus Ultra Touch achieved an overall score of 2178 points and averaged a bandwidth rate of 8MBps here. This score ranks it second-to-last on our charts and goes to show just how much of a practical and sizable difference there is in application performance between a spinning disk and something of the solid-state flavor.

Synthetics - ATTO

ATTO is a simple and free application that SSD vendors commonly use to assign sequential performance specifications to their products. It also gives us insight into how the device handles different file sizes.

In ATTO, the Seagate Backup Plus Ultra Touch lands in last place, with transfer speeds of up to 144MBps read and 148MBps write.

Synthetics - iometer

iometer is an advanced and highly configurable storage benchmarking tool that vendors often use to measure the performance of their devices.

On average, Seagate’s Backup Plus Ultra Touch ranks last overall. During sequential transfers, performance peaked out at 132MBps read/write. Seagate’s Backup Plus Ultra Touch boasts random read latency that comes in at ~8.8ms read and 3.5ms write. This results in an IOPS throughput of 113 IOPS read and 286 IOPS write, which is just a fraction of what something like the SanDisk Extreme or other SSDs are capable of. And, scaling out to a QD of 4 or even 128 doesn’t improve performance much, but rather just exaggerates latency.

Write Saturation and Temperature

Write speed and temperature are two important and inter-related metrics for external devices. We tossed in this one last test to measure the performance of the drive over a 15-minute window. When possible, we also log the temperature of the drive via the S.M.A.R.T. data to see when (or if) thermal throttling kicks in and how it impacts performance. For SSDs, this test also reveals if the drive has a pseudo-SLC cache, which is a small portion of faster-programmed flash that absorbs incoming write workloads. Keep in mind that results will vary based on the workload and ambient air temperature.

Under a straight 14 minutes of write time, Seagate’s Backup Plus Ultra Touch managed to write just over 109GB of data. Surprisingly, this outshines the LaCie Mobile drive significantly, by nearly 30GB. Still, it pales in comparison to its flash-based solid-state competitors.

Over the course of writing the data, we logged the highest temperature of 37C, which is rather low.

    Pretty much zero information about how encryption is handled yet so much emphasis on it as a feature in this whole review (and the title!)
    Do you have to enter the password every time the drive is connected? (I hope so) How does this process look? Performance tested with encryption enabled? (Should be practically zero difference, but for the sake of completeness)

    "If you are into data security, the Backup Plus Ultra Touch is a great secure storage/backup option that is well worth those extra few dollars it commands over the competition."

    I bet the encryption software is Windows-only and Mac/Linux users will have their share of fun if they decided to start using the bundled software first. And in the end it will not be any better than Truecrypt/Veracrypt.

    Average, overpriced 2.5" external drive for 80$. Either you pay 20$ less for a 2TB drive (the USB-C adapter doesn't cost the difference) or pay 10-20$ for a 4TB(!) external drive. Good encasing though with a low temperature of 37°C. 2/5
