The OWC Categorical 1M2 (begins at $119.99; $219.99 for 1TB as examined) has the excellence of being the primary exterior solid-state drive we have examined sporting help for USB4, the most recent USB taste. So it is no shock that the 1M2 is likely one of the quickest exterior SSDs we have now encountered, at the very least when paired with a pc that has both a USB4 or a Thunderbolt 4 port, which each use a USB-C-style connector. The 1M2 will run at decreased speeds should you use it with older {hardware}, nonetheless, and it could require superior software program tweaks to get it engaged on a PC that does have USB4. Coupled with a comparatively excessive worth, this makes it suited solely to tinkerers and early adopters who already know they want its groundbreaking velocity.
Design: Fins to Beat the Warmth
Different World Computing (OWC) is at the very least as well-known for making drive enclosures and housings as it’s for making SSDs, and the Categorical 1M2 is a little bit of each. Its silvery body, designed to carry an M.2 inside SSD, is crafted of aircraft-grade aluminum and is roofed with 20 vertical fins. This makes it resemble a big heatsink of the type you may discover cooling elements inside a desktop PC, and actually the fin design does serve to maximise the dissipation of warmth from the SSD inside. Even so, throughout testing, the drive steadily felt fairly heat to the contact.
The 1M2 is accessible with a PCI Categorical 4.0 SSD (the OWC Aura Extremely IV) inside, in capacities starting from 1TB to 8TB. Alternately, you should buy the enclosure by itself and add your personal SSD. Within the latter case you additionally get a tiny screwdriver with which to open the enclosure. OWC notes that the enclosure ought to work with even bigger M.2 SSDs (16TB, say) as they develop into accessible.
The 1M2 is massive in contrast with most of as we speak’s exterior SSDs, measuring 0.9 by 2.8 by 5.2 inches (HWD), however it could possibly nonetheless slot in a pants or coat pocket. (Simply thoughts that the fin ridges do not get caught on something.) On one brief finish of the drive is a USB-C port that helps USB4—the port’s label identifies it as “USB4 40Gb/s.” The inclusion of a most throughput velocity is a welcome addition to port (and package deal) labeling, significantly as some USB4 gadgets’ speeds will max out at solely 20Gbps and will likely be labeled as such.

You may try the drive household’s full speeds and feeds within the chart under. Word that the sequential learn and write scores within the desk are uncooked scores taken instantly from OWC’s Crystal DiskMark testing on the completely different capacities, quite than the “polished” scores (rounded to the closest 100MBps) that almost all producers present.
Testing the OWC Categorical 1M2: Scorching Pace Over USB4 and Thunderbolt 4
To benchmark the 1M2, we used two completely different Apple MacBook Professional laptops and our newest Home windows storage testbed desktop PC, which we additionally use to check PCIe 5.0 M.2 SSDs. It consists of an ASRock X670E Taichi motherboard, 32GB of DDR5 reminiscence (two Essential 16GB DIMMs), two USB4 ports, one PCIe 5.0 x4 M.2 slot (with lanes which have direct entry to the CPU), and three PCIe 4.0 slots. It sports activities an AMD Ryzen 9 7900 CPU utilizing an AMD inventory cooler and an Nvidia GeForce RTX 2070 Tremendous card, and it’s powered by a Thermaltake Toughpower GF1 Snow 750W PSU. The boot drive is an ADATA Legend 850 PCIe 4.0 SSD. All that is housed in a Praxis Wetbench open-frame case.
After connecting the 1M2 to one of many two native USB4 ports on the testbed’s ASRock motherboard, we ran our common Crystal DiskMark 6.0, PCMark 10 Total Storage, and 3DMark Storage exams, in addition to the AJA System Check. Crystal DiskMark’s sequential velocity exams present a standard measure of drive throughput, simulating best-case, straight-line transfers of huge recordsdata. The PCMark 10 Storage take a look at measures an SSD’s readiness for all kinds of on a regular basis duties. The AJA System Check, accessible for each Home windows and Mac, shouldn’t be usually a part of our testing because it’s much like the Blackmagic take a look at we use on macOS (described under), measuring a drive’s skill to report and play again video. Nevertheless, we used it right here as a examine on the claims that OWC makes in its personal benchmarking outcomes.
At first, the 1M2 skilled points working benchmarks on the Home windows testbed. It took a number of makes an attempt to even run Crystal DiskMark, and when it did full, the outcomes had been inconsistent. Additionally, each PCMark 10 and 3DMark Storage outcomes had been rather a lot decrease than anticipated (decrease than many spinning-disk exhausting drives). And whereas AJA learn speeds appeared cheap, write speeds had been ridiculously low.
OWC recommended that the issues could also be associated to a change in a Home windows default coverage for exterior storage. Beginning in Home windows 10 Model 1809, in late 2018, Microsoft modified the default coverage for exterior storage gadgets from Higher Efficiency to Fast Removing. Whereas the Fast Removing setting lets you detach an exterior drive from its port with out the danger of shedding information, Home windows cannot cache disk write operations underneath this setting, which explains the dismally low settings in our preliminary AJA testing. Altering the setting to Higher Efficiency solved the problem. You are able to do so both by following the directions on this Microsoft article or through the use of OWC’s Disk Efficiency software; we used the latter. It is a comparatively straightforward downside to repair, however OWC ought to make it clear that doing so is important for full efficiency. In the event you’re not conscious, it could take some time so that you can understand that you simply’re not getting the speeds for which this SSD is meant.
With that difficulty out of the way in which, we ran by means of all of the Home windows exams once more. In our Crystal DiskMark testing, the 1M2 proved speedy certainly. With sequential learn and write throughput speeds hovering round 3,000MBps, it simply outclassed the whole thing of USB 3.2 Gen 2×2 SSDs we in contrast it with. The one drive in our comparability group within the 1M2’s league is the Thunderbolt-only WD Black D50 Sport Dock NVMe SSD, which I examined utilizing a Thunderbolt 3-equipped Dell XPS 13 laptop computer. Whereas the D50’s sequential learn rating successfully matched the 1M2’s, its write rating lagged by practically 400MBps. The 1M2’s Crystal DiskMark 4K learn rating is in the course of our group of comparability drives, and its 4K write rating is on the backside. (The 4K scores aren’t as related for exterior drives that do not function a PC’s foremost boot disk.)
We aren’t together with a whole desk of scores for all of the exams we ran on the Home windows testbed, as a result of that is the one USB4 drive we have now examined and nothing else is instantly similar to it. Nonetheless, listed here are some highlights: It had the very best PCMark 10 rating (2,593) of the lot, with solely the Seagate FireCuda Gaming SSD coming remotely shut, at 2,445. Write and skim scores for the video-centric AJA system take a look at had been each within the 2,600MBps vary.
For macOS testing, we reformatted the 1M2—switching from its native Home windows-only NTFS format to the versatile exFAT, which works seamlessly with Home windows, macOS, and Linux—on a MacBook Professional with a Thunderbolt 3 connection. We then ran the identical exams (Blackmagic, and our personal folder switch take a look at) on a MacBook Professional with an M3 processer over a Thunderbolt 4 connection.
Over a Thunderbolt 3 connection, the 1M2’s Blackmagic scores of 948.2MBps for each learn and write are what we might count on for a USB 3.2 Gen 2×2 exterior SSD. With Thunderbolt 4, the outcomes had been a lot quicker: 2,625MBps write and a couple of,180MBps learn. It took a mere second to pull, drop, and save our 1.2GB take a look at folder, placing it in an elite group that features the Samsung Transportable SSD T9, the Essential X10 Professional, the Kingston XS2000, the WD Black D50, and some different drives.
Verdict: A Zippy Exterior SSD, if You Have What It Takes
Showing within the type of a brash, finned aluminum heatsink enclosing a PCI Categorical 4.0 M.2 SSD, the OWC Categorical 1M2 exterior SSD cuts a placing determine. It tallied quick benchmark scores over USB4 and Thunderbolt 4, however you will want a pc with certainly one of these ports to reap its velocity advantages. Additionally, when working the 1M2 on a Home windows laptop, you might must tweak an deep setting within the working system to get constant efficiency out of it.
(Credit score: Joseph Maldonado)You pay a premium for the OWC Categorical 1M2, however should you’re in search of speedy transfers of huge recordsdata, it could match the invoice when you’ve got the precise {hardware}. It is available in capacities as much as 8TB, or should you’re a DIY-er, you might need to purchase the enclosure alone and add your personal PCI Categorical M.2 SSD.
The 1M2 is the primary of what we count on to be many USB4 exterior SSDs. It is off to an excellent begin, although it isn’t an apparent selection for anybody however early adopters who already know they want its appreciable high speeds and have a USB4 or Thunderbolt 4 port to allow them.
