Finest Costs Right this moment: Satechi DotDisk 80Gbps SSD enclosure
Setachi’s DotDisk is an 80Gbps SSD enclosure that may accommodate a single NVMe SSD. It’s uniquely moveable, because it employs energetic cooling within the type of a small fan slightly than the cumbersome passive cooling fins most 80Gbps enclosures function.
But, regardless of its svelte profile, the DotDisk proved a top-flight performer. I just like the efficiency, the dimensions, and the look.
Learn on to study extra, then see our roundup of the most effective exterior drives for comparability.
What are the Setachi DotDisk’s options?
As mentioned, the pewter- or silver-colored, all-aluminum DotDisk is slightly tiny for a high-speed enclosure. It measures a mere 3.9-inches lengthy, by 1.4-inches extensive, by 0.7-inches thick and weighs simply shy of 4 ounces when populated.
These dimensions make it far simpler to move than most 80Gbps (and even 40Gbps) enclosures, but additionally imply it has much less floor space to shed warmth. That did come into play with some older, much less vitality environment friendly SSDs, regardless of the small 1-inch fan situated on the underside of the PC board.
The Satechi ships with a 12-inch Thunderbolt 5 cable — which I actually respect. I’ve skilled too many points with cheaper USB4/120Gbps cables just lately to belief them. I’ve by no means had an issue with a Thunderbolt cable in properly over a decade. More than likely as a result of a really strict certification course of.

Entry to the inside is gained by way of a single, slightly tiny non-captive screw. Watch out, it’s very straightforward to drop regardless of the magnetic screwdriver included within the package deal. Each the inner and exterior screws are pentagonal, so use (and don’t lose) the offered instrument.
One exceedingly minor gripe: The directions contained in the field (properly printed on the tray holding the drive the place you’ll spot them instantly) say that you just take away the inner screw from the captive mounting nut. There wasn’t one.
There have been, nonetheless, two (one spare) contained in the package deal additionally containing the thermal strip, in addition to a spare for the screw securing the lid. As I’ve despatched a couple of tiny screw skittering throughout my hardwood flooring, solely to be discovered later with the vacuum cleaner, I respect spares.
How a lot is the Satechi DotDisk?
The DotDisk is financially on par with different 80Gbps enclosures at $200 retail. By means of comparability, the OWC 1M2 80Gbps retails for $220, and the Terramaster D1 SSD Professional for $250. There are reductions accessible for these latter two (they’ve been accessible fairly a bit longer) that shut the hole, however the DotDisk is priced appropriately. At the very least with respect to the present 80Gbps market.
I’d be remiss if I didn’t inform you that 40Gbps enclosures are about half the value of the 80Gbps selection, nonetheless fairly darn quick, and to us, the candy spot within the worth/efficiency ratio. 40Gbps SSDs are twice as quick as 20Gbps SSDs, that are in flip, twice as quick as 10Gbps SSDs. Nonetheless, 80Gbps SSDs are solely roughly 50 % quicker (6GBps versus 4GBps) than 40Gbps fashions.
(10Gbps enclosures are by far the most affordable exterior answer and can nonetheless fulfill most missions. 20Gbps are decently inexpensive as properly, however operate at solely 10Gbps except you’ve a USB3.2×2 port. That features when connected to most Thunderbolt ports.)
It’s probably the most moveable USB4/Thunderbolt 5 possibility I’ve examined — by rather a lot.
How does the Satechi DotDisk carry out?
When it comes to velocity, the DotDisk left completely nothing to be desired. With a 2TB Essential T710 PCIe 5.0 SSD inside, it cruised to the numbers you see under. Candy. However take these numbers with a small grain of salt — the T710 is a really quick SSD.
That stated, the DotDisk proved an especially adept reader with giant sequential information.

Whereas nonetheless very quick with smaller information, the DotDisk/Essential T710 combo was outpaced by the OWC 1M2 80Gbps with its Aura Extremely IV SSD within the CrystalDiskMark 8 32-queue 4K exams. Word that Home windows doesn’t presently use a number of queues.

Our real-world 48GB transfers confirmed that the artificial benchmarks weren’t flukes, although the DotDisk was nonetheless outpaced by the OWC 1M2 80Gbps and — surprisingly, given its different not-always-stellar-for-80Gbps outcomes — the LaCie Rugged SSD Pro5.

The Satechi DotDisk was proper heading in the right direction with the 450GB write, albeit a tad slower than the TerraMaster D1 SSD Professional and OWC 1M2 80Gbps.

Word that you just’ll see roughly the identical efficiency for fewer Franklins with a PCIe 4.0 NVMe SSD contained in the DotDisk. Or every other 80Gbps enclosure for that matter. Many PCIe 4.0 NVMe SSDs are able to 7GBps to 8GBps throughput, which is quicker than the USB4/Thunderbolt 5 bus appears able to delivering.
The DotDisk enclosure runs fairly heat regardless of the fan, which you’ll be able to hear fairly clearly when the drive is being harassed. However the expertise was additionally variable relying to the SSD inside. An older TeamGroup GE Professional ran significantly hotter than the Essential T710. I suppose there’s one thing to SSD distributors’ claims about decrease energy utilization for newer designs, in spite of everything.
Not that I anticipate the DotDisk’s fan to fail, however the opportunity of such is the rationale many 80Gbps enclosures comparable to Terramaster’s D1 sequence and OWC 1M2’s select passive cooling by way of large fins. The draw back to those significantly bigger designs is that additionally they want a variety of house round them for convection.
I’ll confess that I have a tendency to stick with 10Gbps/20Gbps exterior SSDs for many purposes — they produce far much less warmth and eat much less vitality.
Power and warmth apart, the DotDisk is a superb performer that by no means throttled throughout a number of check runs. Good job, Satechi!
Do you have to purchase the Satechi DotDisk?
If you need 80Gbps velocity that matches simply in your pocket (who doesn’t?), the DotDisk is the way in which to go. It’s probably the most moveable USB4/Thunderbolt 5 possibility I’ve examined — by rather a lot.
But when portability isn’t a priority, a passively cooled answer could possibly be the safer possibility for continuous, set-it-and-forget-it use.

How we check
Drive exams presently 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).
10Gbps, 20Gbps USB, and Thunderbolt 5/USB4 are built-in into the motherboard. Intel CPU/GPU graphics are used. Inner 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 system’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 attainable.
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 executed with a RAM disk serving that goal.
Every check is carried out on a NTFS-formatted and newly TRIM’d drive so the outcomes are optimum. Word that in regular use, as a drive fills up, efficiency might lower as a result 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.
