Although it was a bit tough across the edges when it comes to backwards compatibility, my first have a look at 80Gbps Thunderbolt 5 storage reveals a really good uptick in efficiency — about twice the 40Gbps of Thunderbolt 3/USB 4 in sure benchmarks. Logical.
By the use of comparability, that’s roughly as quick as an NVMe SSD on the PCIe 4.0 bus. And a PCIe 4.0 NVMe SSD is strictly what’s contained in the OWC Envoy Extremely moveable drive I used to check Thunderbolt 5 storage.
Notice that you just’ll see 120Gbps listed within the Thunderbolt 5 specs, however that’s uni-directional output for driving a number of high-resolution shows. Bi-directional transfers reminiscent of these utilized by storage gadgets are “limited” to 80Gbps, or roughly 6- to 7GBps after overhead.
How properly does Thunderbolt 5 work?

My debut have a look at Thunderbolt 5 got here courtesy of the aforementioned Envoy Extremely connected to a Thunderbolt 5, 32GB Maingear ML-17 (Mk. II) laptop computer. Clearly, I wasn’t in a position to make use of the 59GB RAM disk in my customary take a look at PC for 48GB transfers, however the T-Pressure NVMe SSD within the laptop computer offered a decently quick substitute.
Alas, the Envoy Extremely fully failed to seem on our official Asus ROG Strix Z790-I (Thunderbolt 4) take a look at mattress. It didn’t seem within the BIOS, disk supervisor, or the Thunderbolt utility. The problem is being cooperatively investigated by OWC, Intel, and Asus because the drive didn’t enumerate on an Asus Maximus Z890 Hero board as properly. In case you weren’t conscious, Thunderbolt 5 is meant to be full backward appropriate with variations 3 and 4.
Additional, solely the newer Sonoma and Sequoia variations of macOS would acknowledge the Envoy Extremely to be used on my Apple Silicon Mac Studio, although it was enumerated on the Thunderbolt bus in System Information way back to Ventura. Sequoia is required for Intel-based Macs.
Lastly, I used to be unable to check on older Thunderbolt 2 methods because the Envoy Extremely sports activities a captive Kind-C cable which prevented me from using Apple’s Thunderbolt 2 to three adapter.
That is an especially small pattern measurement of apparatus, so I’m unsure simply how pervasive the problems are, however there have been rumblings across the business in regards to the present state of compatibility. It’s undoubtedly toe-in-water-time for Thunderbolt 5 — even for early adopters.

What Thunderbolt 5 gear is out there?
One other Thunderbolt 5 laptop computer presently transport is the Razer Blade 18. Each Asus and Gigabyte have introduced a slew of motherboards that both function Thunderbolt 5 or sport headers to allow them to be upgraded to it by way of add-on playing cards.
Are you able to improve older computer systems with add-on playing cards? Based on my inquiries, no. There are some intelligent engineers and hackers on the market, however there are timing points and different components that make porting backwards extremely unlikely. Yup, you’ll want new stuff to get Thunderbolt 5 speeds. And notice that neither Thunderbolt 4 or 5 are appropriate with older Thunderbolt 2.
How briskly is Thunderbolt 5 storage?
How about 6GBps sequential studying, and practically 4GBps sequential writing with a number of queues? Then there’s practically 4GBps sequential studying and writing single-queued. That’s a really good bump up from the earlier highs of round 3GBps multi-queued and a couple of.5GBps single-queued delivered by 40Gbps USB 4.
It’s about what we’d anticipate from doubling bandwidth from 40Gbps to 80Gbps. You possibly can see the proof under from CrystalDiskMark 8.
Nonetheless, relating to random efficiency beneath CrystalDiskMark 8, the take a look at image painted no explicit enchancment. This stands to purpose as elevated throughput isn’t going to assist any drive discover/search knowledge quicker.
To reiterate, this was a pre-production drive on a brand-new laptop computer fairly than our official take a look at mattress. As I needed to switch my 48GB information from SSD to SSD I omitted these outcomes. Nonetheless, in whole with this association the Envoy Extremely nonetheless completed a mere second slower than the primary place OWC 1M2 — simply inside the margin of error for these checks.
We additionally omitted the outcomes for our typical 450GB write because it’s extra a take a look at of the SSD inside and the quantity of secondary cache it affords, fairly than the pace of the bus. The Envoy Extremely was on tempo for a stellar end result if it hadn’t slowed to 1.2GBps when secondary cache was exhausted.
Once more, official Envoy Extremely numbers must wait till we improve our take a look at mattress to Thunderbolt 5. The take a look at outcomes above are merely as an instance the tough distinction between Thunderbolt 3/4, USB 4, 10Gbps USB, and Thunderbolt 5 efficiency.
In summation, there was a marked improve in sequential transfers — with a number of queues and with just one. On suitably quick methods, it ought to prevent time. As soon as once more, random ops are minimally improved so don’t anticipate an uptick in lots-of-small-files situations.
Notice that these checks have been run on a pre-production model of the Envoy Extremely, although OWC did finally get a transport model to us.
What does Thunderbolt 5 imply for you?
Thunderbolt 5 is right here and also you most likely need it (we do), even when it saves you solely modest quantities of time in the actual world. Time is cash, in fact, however to see a revenue, you’ll have to beat some hefty preliminary investments — the 2TB OWC Envoy Extremely I examined is $400 and the 4TB is $600. Gulp.
Thunderbolt 5 motherboards and Home windows laptops are priced for the top-shelf as properly, and the excessive cost-to-performance ratio carries over to the Mac. Solely high-end newbies such because the Mac Mini (M4 Professional) provide Thunderbolt 5.
Lengthy story quick… For the nonce, Thunderbolt 5 is for adventurous early adopters, lovers, and prosumers who really want the pace, and have the software program and {hardware} to make the most of it. That is par for the course with any new expertise, although we don’t keep in mind these type of compatibility points with Thunderbolt 4.
Most people will probably be simply wonderful with inexpensive and — in the intervening time — extra reliable 40Gbps Thunderbolt 4 and USB 4, together with our top-rated exterior drive, the Adata SE920.
