The D1 SSD is our third foray into Terramaster’s sequence of rugged, aluminum exterior SSD enclosures, following on our earlier evaluations of the 80Gbps D1 SSD Professional and 40Gbps D1 SSD Plus. This unit is kind of a bit smaller, and in contrast to the others carries an IP67 ranking. It’s rated at 10Gbps and for probably the most half it carried out as such.
Nonetheless, I used to be astounded to see it learn at over 4GBps and write at 2GBps through our Thunderbolt 5 port. Sadly, the bizarrely quick efficiency was additionally accompanied by a number of system points soI don’t suggest you strive what I found to.
Learn the efficiency part for the complete skinny on this fascinating conduct that I by no means even knew was doable.

What are the Terramaster D1 SSD’s options?
Very similar to its cousins, the D1 SSD is a finned aluminum enclosure. Nonetheless, in contrast to its different relations, it sports activities a rubber grommet surrounding the inside that seals the unit to forestall moisture and dirt from getting into. You may see it within the picture under.
The D1 SSD measures roughly 4.5-inches lengthy, by 1.75-inches broad, by 0.75-inches thick and weighs solely round 5.5 ounces loaded. Terramaster offers a cultured, zippered hard-shell case for the unit in addition to a Sort-C cable and screwdriver to assist with putting in an SSD.
I do have one criticism as regards the D1 SSD’s design — it’s not fairly as simple to marry the 2 halves of the enclosure correctly. There are two tabs on the highest that seat in two dents within the backside and it took some jockeying to get them to suit collectively correctly.
When they’re oriented accurately, the ends shall be flush and the captive screw that holds the 2 halves collectively will flip simply. Once they aren’t, it gained’t.
How a lot is the Terramaster D1 SSD?
The D1 SSD is dust low cost for a weatherized IP67-rated aluminum enclosure that runs tremendous cool: $40. After all, you’re by yourself for the NVMe SSD. Something PCIe 3.0 or later will work as all simply outstrip 10Gbps USB. That stated, I used PCI 4.0 and 5.0 sorts to check, and that allowed the next to happen.
How briskly is the Terramaster D1 SSD?
Earlier than I get into the D1 SSD’s regular 10Gbps outcomes (they had been good, and if that’s all you’re interested by — skip just a few paragraphs). I’m going to jot down a bit a few phenomenon I’ve by no means seen, and didn’t assume was doable.
Observe that if I hadn’t first connected the D1 SSD to a Thunderbolt 5 port through a Thunderbolt cable I would by no means have skilled the next. Nonetheless, having carried out so…
…the 10Gbps D1 SSD was capable of learn at 4GBps like a 40Gbps SSD, and write at round 2GBps like a 20Gbps SSD. Critically? This even continued once I plugged right into a USB 3.2×2 port, which needs to be capped at 20Gbps.
It took some time to determine what was making this leap in efficiency, however apparently the D1 SSD was first enumerated by Home windows as an inner NVMe SSD. Certainly checking drive properties, the stornvme driver was getting used relatively than the traditional UASPStor. Apparently, pure PCIe communications are doable even via a USB port when this occurs. A minimum of on our take a look at mattress (described on the backside of this text).
Under you’ll be able to see that the system acknowledged the SSD contained in the enclosure, not the enclosure itself.
Alas, whereas the efficiency was implausible — different points arose. First, when subsequently connected to an M4 Max Studio, the D1 SSD enumerated as a 1TB Orico drive in Disk Utility and didn’t present up in Finder. To be truthful, the 2TB T-Drive SSD inside might have been put in in an Orico enclosure beforehand. Leftover enumeration information? Is Terramaster working with Orico? Can’t say.
Swapping in a 2TB Solidigm PCIe 4.0 SSD cured the difficulty on the Mac, however when reattached to our take a look at mattress, Disk Supervisor confirmed two drives that wanted initialization: one sadly being my Linux Mint set up. Why that was trashed, I can’t say, however my greatest guess is that eradicating the D1 SSD whereas the system was operating screwed up the enumeration desk. Inside NVMe SSDs aren’t usually hot-swappable.
With the Solidigm SSD put in, the take a look at outcomes on our Home windows take a look at mattress had been roughly the identical 4GBps/2GBps I noticed the primary go-round. On macOS and Linux Mint, the drive learn and wrote at round 1GBps, which is the norm the 10Gbps.
Utilizing Diskpart to scrub, reinitialize, and partition the SSD, then rebooting and utilizing the USB 3.2×2 port, lastly enumerated the D1 SSD as an exterior USB SSD.
This isn’t the primary time I’ve skilled oddities with Terramaster firmware. The D1 SSD Professional wouldn’t write at 80Gbps with the cable it shipped with till a firmware replace was offered. I say firmware, as a result of different exterior SSDs utilizing the Realtek RTL921 bridge chip (PCIe 4.0 internally) discovered contained in the D1 SSD have by no means exhibited this sort of conduct earlier than.
The charts under present each the traditional 10Gbps and enumerated-as-NVMe numbers (gentle blue). When it comes to 10Gbps efficiency, the D1 SSD is true up there with the most effective of them.
The CrystalDiskMark 8 4K learn numbers under are additionally fairly good for 10Gbps.
At 10Gbps the D1 SSD was quicker than its rivals in some 48GB transfers, and slower in others. Once more, operating enumerated as NVMe, the numbers had been simply foolish quick.
But extra NVMe bedazzlement got here courtesy of the D1 SSD’s 450GB write occasions, which had been additionally superior to the opposite two drives (the Seagate Extremely Compact SSD and Adata SC735) at true 10Gbps. Observe that FastCopy makes much less distinction throughout lengthy writes.
The D1 SSD proved a better-than-solid performer on the 10Gbps norm. However seeing the sort of velocity I noticed with the drive enumerated as NVMe raises a slew of questions. How is it even doable, and why can’t extra exterior enclosures act this manner? Only for starters.
Do you have to purchase the D1 SSD?
The D1 SSD appears to be like cool, runs cool, is weatherproof, and is super-affordable for such high quality building. I’m guessing you gained’t be capable to futz the NVMe factor after Terramaster updates the firmware, nor do you have to run the chance of trashing different drives in your system. That stated, it was hella’ cool seeing a 10Gbps USB SSD learn at 40Gbps.
In the event you do attempt to mimic my outcomes, which can stem partly from my expertise for borking in any other case steady merchandise (it’s a blessing, it’s a curse), I counsel that you just by no means pull the drive off the system. Particularly when powered on.
I bear zero accountability for any makes an attempt to make use of this product in a fashion not in line with utilizing a traditional 10Gbps USB SSD.
How we take a look at
Drive exams at present make the most of Home windows 11 24H2, 64-bit operating off of a PCIe 4.0 Samsung 990 Professional in an Asus Z890-Creator WiFi (PCIe 4.0/5.0) motherboard. The CPU is a Core Extremely i5 225 feeding/fed by two Essential 64GB DDR5 5600MHz modules (128GB of reminiscence complete).
Each 20Gbps USB and Thunderbolt 5 are built-in into the motherboard and Intel CPU/GPU graphics are used. Inside PCIe 5.0 SSDs concerned in testing are mounted in an Asus Hyper M.2 x16 Gen5 adapter card sitting in a PCIe 5.0 slot.
We run the CrystalDiskMark 8.04 (and 9), AS SSD 2, and ATTO 4 artificial benchmarks (to maintain article size down, we report solely the primary) to search out the storage gadget’s potential efficiency. Then we run a sequence of 48GB switch and 450GB write exams utilizing Home windows Explorer drag and drop to indicate what customers will see throughout routine copy operations, in addition to the far quicker FastCopy run as administrator to indicate what’s doable.
A 25GBps two-SSD RAID 0 array on the aforementioned Asus Hyper M.2 x16 Gen5 is used because the second drive in our switch exams. Previously the 48GB exams had been carried out with a RAM disk serving that function.
Every take a look at is carried out on a NTFS-formatted and newly TRIM’d drive so the outcomes are optimum. Observe that in regular use, as a drive fills up, efficiency might lower as a consequence of much less NAND for secondary caching, in addition to different components. This challenge has abated considerably with the present crop of SSDs using extra mature controllers and much quicker, late-generation NAND.
