Seagate Backup Plus Portable 5TB & Backup Plus Slim 2TB Review: SMR for the Consumer Marketby Ganesh T S on June 18, 2019 8:00 AM EST
Hard drives continue to remain the storage media of choice for cost-conscious consumers with bulk storage requirements. HDD vendors have typically used their 2.5" drives for bus-powered high-capacity models. This market segment has been stuck at the 4TB mainstream capacity point for a few years now, with the z-height of the models coming in at well over 15mm. Earlier this year, Seagate announced an update to their massive 5TB Backup Plus Portable, while also introducing a new svelte 2TB Backup Plus Slim external hard drive. Both of them adopt SMR platters (similar to the Backup Plus models being sold since late 2016), and given the performance impact of SMR, today we'll be taking a detailed look at how SMR in bus-powered hard drives behaves for consumer workloads.
Introduction and Product Impressions
The number of vendors delivering portable, bus-powered hard drives is limited: only Seagate, Western Digital, and Toshiba serve this market. Of these, only Seagate has a 5TB model in the market currently. While Western Digital and Toshiba use conventional magnetic recording (CMR) for their 2.5" hard drives, Seagate makes use of shingled magnetic recording (SMR). This enables higher data storage density in their platters, which, in turn enables them to deliver the highest capacity 2.5" hard drives. The high density platters also allows them to deliver slim hard drives (at industry-leading capacity points taking thickness into consideration). Today, we are taking a look at the high-capacity Seagate Backup Plus Portable 5TB drive and the ultra-thin Seagate Backup Plus Slim 2TB dual-platter drive.
Mass-market bus-powered hard drives typically employ a USB 3.0 micro-B interface port (contrast this with the LaCie Porsche Design Mobile Drive that comes with a Type-C port). The Seagate Backup Plus models we are looking at today belong to that category. Seagate's portable drives have come with different value additions over the last several years. A few years back, the drives came with free cloud storage (OneDrive) for a limited time. Recently, we have seen them bundle a two-month subscription to Adobe's Creative Cloud package with select models. The Seagate Backup Plus models also come with value additions: In addition to the aforementioned Creative Cloud, Seagate also offers the Mylio Create cloud-based photo organization feature.
Package-wise, the two drives are remarkably similar. They come with a 18 inch. USB 3.0 Type-A male to Micro-B male cable. The cable color depends on the color of the drive itself. Other than that, we have a quick-start guide and a bunch of papers describing the value additions.
The drives come pre-formatted in exFAT, guaranteeing compatibility with both Macs and Windows-based systems. A setup executable is also available to help users get step-by-step guidance for product registration, warranty activation, and redemption of the value additions.
Moving on to the technical details, we get a quick understanding of the internals using CrystalDiskInfo.
|Internal Drive Characteristics|
Typical of bus-powered hard drives, both the Seagate Backup Plus Portable and Slim are 5400 RPM drives. It turns out that the internal drive of the Portable (the ST5000LM000) is available in the retail market as a Seagate BarraCuda Compute drive, while the one in the Slim (the ST2000LM007) is marketed as a Seagate Mobile HDD.
We have reviewed a number of bus-powered hard drives over the last few years. The table below presents the detailed specifications and miscellaneous aspects of all those units and how the two Seagate Backup Plus models being reviewed today compare against them.
|Comparative HDD-Based Direct-Attached Storage Device Configurations|
|Bridge Configuration||SATA III to USB 3.0 Micro-B||SATA III to USB 3.0 Micro-B|
5TB 5400 RPM 2.5" SATA Hard Drive
Seagate Barracuda Compute
2TB 5400 RPM 2.5" SATA Hard Drive
Seagate Mobile HDD
|Physical Dimensions||115.3 mm x 20.9 mm x 80 mm||114.8 mm x 11.7 mm x 78 mm|
|Weight||265 grams||126 grams|
|Cable||USB 3.0 Micro-B to Type-A||USB 3.0 Micro-B to Type-A|
|Review Link||Seagate Backup Plus Portable 5TB Review||Seagate Backup Plus Slim 2TB Review|
The key things to note here include the thickness of the Backup Plus Slim and with its weight. With a z-height of 11.7mm, it is comfortably the thinnest external hard-drive we have reviewed. At 126g, it comes in at barely half the weight of the other models in the above table.
In the rest of this review, we first take a look at our standard direct-attached storage benchmarks. Following this, we have some performance measurements from a typical external HDD real-world use-case. Finally, we talk about power consumption and provide some concluding remarks.

StevoLincolnite - Tuesday, June 18, 2019 - linkPass... It's a Seagate.
Would be nice to get more mechanical disk benchmarks happening though, especially some of the larger 8-10TB+ drives.
MrSpadge - Tuesday, June 18, 2019 - linkYeah, I've also seen at least one Seagate drive die. Never ever should anyone buy them again!
29a - Tuesday, June 18, 2019 - linkIf you're in it long enough you'll see all brands die.
Death666Angel - Tuesday, June 18, 2019 - linkI think MS was being sarcastic by indulging in SLs nonsense comment.
StevoLincolnite - Tuesday, June 18, 2019 - linkNot a nonsense comment.
Nor did I mention anything about reliability... That was just an assumption by MrSpadge.
Oliseo - Sunday, June 23, 2019 - linkHere's the thing, the English language is such that you don't have to literally mention reliability for everyone to know that's exactly what you were talking about.
Or are you now claiming everyone else was wrong to infer what you implied? In which case, the onus is on you to be more explicit in future to what you're actually talking about.
StevoLincolnite - Monday, June 24, 2019 - linkRubbish Oliseo.
Then again, if people automatically assumed I was talking about the drives reliability, maybe that just says everything about Seagates track record?
I was actually talking about warranty, or lack there-of here... I don't want to have to send anything overseas for replacement/repair.
eek2121 - Tuesday, June 18, 2019 - linkI have some hard drives that would like to disagree with you. Including a 10 MB one. MB. Not GB.
Henry 3 Dogg - Sunday, January 30, 2022 - linkunless you made it yourself, I've seen a drive of that brand die
eek2121 - Tuesday, June 18, 2019 - linkI had the 5 GB drive die after 3 months of use. No more seagate for me. Loved the form factor though. These drives are small.
