Seagate One Contact SSD (2021) Evaluation: Double Efficiency

Not way back, Samsung launched a transportable SSD vary referred to as the T7 Contact. The ‘contact’ in that exact line was a reference to the built-in fingerprint safety sensor that allowed the contents saved on it to be secured biometrically.

Wouldn’t it be an affordable conclusion that the Seagate One Contact is identical? No, it’s purely branding. The mannequin quantity is ‘STKG500400’ with ‘1000’ or ‘2000’ within the center for 1- and 2TB capacities. I’ve examined the 1TB mannequin right here.

And, to pour extra gasoline on this branding bonfire, Seagate launched a earlier One Contact (STJE) again in 2019, reviewed right here by me, that had solely a USB 3.zero interface (USB 3.1 Gen 1) and never the USB 3.2 Gen 2 interface of the brand new product.

These factors apart, the brand new One Contact SSD is coming into an enviornment occupied by some notably good and reasonably priced moveable SSDs accessible, just like the Essential X8.

Does it have the efficiency, seems and deserves to chop a slice of this profitable sector, or is it heading to the discount bin?

Design & Construct

What’s tough to gauge within the official pictures of the brand new One Contact SSD is that it’s a lot smaller than most prospects are more likely to anticipate. The unique design was diminutive, and that is even smaller.

At simply 70mm lengthy and 50mm vast, that’s a lot smaller than a 2.5in drive and solely a bit greater than an mSATA module. And, at lower than 80g together with cables, it’s additionally remarkably light-weight and subsequently simple to pocket.

Building is generally plastic, with a material end on the edges and an aluminium cowl on the highest. Given the low weight of the One Contact SSD, I believe that the steel prime panel is remarkably skinny, even it’d supply some extra safety from unintended abuse.

Out of the field, it comes with two USB cables that cowl each USB-C and USB-A. connections. The port on the drive is USB-C.

I used to be instantly struck by how brief these cables are, though it isn’t unusual. Should you exclude the bayonet holding parts, the cable in between is simply 14cm lengthy. Whereas that’s tremendous for utilizing the drive with a laptop computer, these connecting to the rear port on a desktop pc will discover this restricted size unhelpful.

The one different bodily characteristic of notice is a small exercise LED on the facet with the USB-C port, which isn’t one of the best place to be simply seen. It additionally is available in three colors; black, silver and blue.

It’s also value noting for potential patrons that you could be need to retain the field, as Seagate doesn’t present any pouch for the drive and accompanying cables. I am positive that when these grow to be commonplace, and they’re going to, some wonderful third-party circumstances will seem to deal with this shortcoming.

Specs & Options

The One Contact SSD is available in nearly de facto capacities of 500GB, 1TB and 2TB, and the evaluate {hardware} we examined contained 1TB of flash storage. 

For the reason that makers need the pliability of adjusting suppliers primarily based purely on price, precisely what NAND modules and controller that the drive makes use of aren’t documented by Seagate. However it could be cheap to imagine that it makes use of the identical expertise that’s within the Seagate Barracuda NVMe drives, overspecified for the necessities of this USB related expertise.

Whereas the drive will work with older USB 3.zero ports, it was designed for the newest USB 3.2 interfaces in each USB-A and USB-C flavours.

The drive comes pre-formatted within the exFAT file construction, enabling it to work with most fashionable Home windows PCs, Apple Mac and even Android telephones with out the necessity for a reformat. On the drive is {hardware} registration instruments for Home windows and Mac OS (however not Linux), though you possibly can delete these and make extra capability accessible if you happen to like.

What’s lacking is any {hardware} encryption choices, though it’s doable to make use of any folder encrypting software program on this system for extra safety. Take into account the Samsung T7 Contact (additionally USB 3.2 Gen 2) if you’d like biometric encryption.

With this characteristic set, the Seagate One Contact SDD is supposed to be a remarkably simple resolution that solely requires the person to have the ability to join it utilizing USB and perceive how drive letters and folder constructions work.

Software program

The unique One Contact SSD got here with a free utility referred to as Sync Plus (1.5.02), and Seagate has retained this free software program in a downloadable toolkit you can get once you register the product.

A mechanism to seek out the registering internet areas is included on the drive, making the method remarkably simple. When you’ve downloaded and put in the Toolkit, you possibly can create guidelines for copying native folders to the exterior drive dynamically. There may be some management of the sync doable, enabling full bi-directional operation, or regionally deleted information may be retained on the exterior drive.

That is the one characteristic that every one exterior drive house owners want probably the most, and Seagate deserves credit score for creating an efficient resolution and together with it within the value of the One Contact. Word that Sync Plus solely works with Seagate exterior drives.

There’s additionally an app for Android however you will want a telephone or pill with USB-C to plug the drive in.

Together with Sync Plus, Seagate promotes Adobe Mylio, a photograph organisation and distribution service that was as soon as free, and now has a Premium paid possibility, by together with a one-year subscription. And, you too can get an introductory four-month Adobe Inventive Cloud Images plan, double the interval that the earlier One Contact bundle had.

Whereas both of those lures is likely to be useful for people who at all times supposed to make use of these providers, for people who haven’t any intention to reinforce Adobe already substantial coffers, they’re of little worth. Registration additionally seems to generate many follow-up emails from Mylio, greater than I take into account cheap.

Whereas being cute and extremely moveable, these points could be largely moot if the insides don’t carry out effectively, so let’s discover that side of the One Contact SSD.


Trying again at its predecessor, one of the best the primary era One Contact SSD drives might handle was learn speeds round 412MB/s and writes of round 402MB/s.

This efficiency stage was primarily because of the restricted bandwidth of the USB 3.1 Gen 1 interface coupled with an SSD utilizing repurposed SATA SSD expertise.

The brand new One Contact makes use of NVMe drive expertise and a USB 3.2 Gen 2 interface with double the theoretical bandwidth. This enhancement makes it’s greater than double the velocity of its predecessor.

The crucial element right here is that it will probably obtain these speeds if you happen to plug it right into a Gen 2 port, however it will likely be much less if you happen to use an outdated USB 3.zero port (now referred to as USB 3.1 Gen 1).

My exams connecting the brand new drive into an outdated USB 3.zero port returned learn speeds of 456MB/s and writes of 459MB/s. Higher than its predecessor, however hardly an enormous enchancment.

Nonetheless, connecting to a USB 3.2 Gen 2 connection revealed a way more spectacular 1,023MB/s reads and 991MB/s writes. These scores are near the 1,200MB/s theoretical restricted for USB 3.2 Gen 2 and as fast as the higher exterior SSDs we’ve not too long ago seen at Tech Advisor.

In sustained ‘actual world’ exams the place writing continues till the onboard cache is exhausted, efficiency dropped to 864MB/s. That’s extremely respectable and higher than some NVMe M.2 SSDs I’ve benched.

Total, the efficiency of the brand new One Contact SSD is strikingly superior to that achieved by the outdated one.


Within the UK, Seagate doesn’t promote instantly by its official website. It formally prices £79.99 (500GB), £134.99 (1TB) and £254.99 (2TB). You’ll have to pay a bit greater than these costs at Amazon.

American costs are US$94.99 (500GB), US$169.99 (1TB) and US$309.99 (2TB), and once more you will have to purchase it elsewhere together with Amazon.

When on the lookout for this product, we advocate you test the serial code. The 2021 mannequin is STKG1000400 (401, 402 and 403), the place the older mannequin is a part of the STJE1000400 sequence.

Should you don’t want the improved efficiency of the brand new drive, the older STJE1000400 may be sourced for much less money, with the 1TB mannequin being round £113/US$127.99 from many on-line retailers.

Given the staggeringly small enhancements we’ve seen throughout latest CPU and GPU generations, it’s refreshing to see such a considerable efficiency increase on a product line because the Seagate One Contact SSD has skilled.

The win-win of this launch is you can both have the newest and quickest One Contact SSD for an affordable value or choose up the older model for a tune whereas inventory nonetheless exists.

In comparison with different USB 3.2 Gen 2 drives, the brand new One Contact SSD is attractively priced, performs effectively and is very transportable. My solely reservation is that in comparison with the Essential X8, it gained’t deal with the identical stage of informal abuse even whether it is removed from fragile.

By not putting the fragile electronics inside a thick steel tube, Seagate made a drive that’s extremely mild and pocketable. And, with the free Sync Plus software program, you’ve gotten the instruments to make it copy away vital information with out having to make express file transfers.

Total, just like the earlier Seagate One Contact, the brand new system has greater than sufficient robust factors to make it a preferred alternative. I solely want that Seagate had included a small carry case to maintain the drive and its cables collectively.
