Although it was a bit tough across the edges when it comes to backwards compatibility, my first take 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.
Be aware that you simply’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 corresponding to these utilized by storage units are “restricted” to 80Gbps, or roughly 6- to 7GBps after overhead.
How nicely does Thunderbolt 5 work?

My debut take 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 ready 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 utterly 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 did not enumerate on an Asus Maximus Z890 Hero board as nicely. 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 Data way back to Ventura. Sequoia is required for Intel-based Macs.
Lastly, I used to be unable to check on older Thunderbolt 2 techniques 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 a particularly small pattern dimension of kit, so I’m unsure simply how pervasive the problems are, however there have been rumblings across the trade in regards to the present state of compatibility. It’s positively toe-in-water-time for Thunderbolt 5 — even for early adopters.
Be aware that after a Z790-I BIOS replace (9901) offered by Asus on November twenty fifth, 2024, the Envoy Extremely was acknowledged and carried out as anticipated.

What Thunderbolt 5 gear is obtainable?
One other Thunderbolt 5 laptop computer at present 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 through 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 be aware that neither Thunderbolt 4 or 5 are appropriate with older Thunderbolt 2.
How briskly is Thunderbolt 5 storage?
How about 6GBps sequential studying, and almost 4GBps sequential writing with a number of queues? Then there’s almost 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 pair of.5GBps single-queued delivered by 40Gbps USB 4.
It’s about what we’d anticipate from doubling bandwidth from 40Gbps to 80Gbps. You’ll be able to see the proof beneath from CrystalDiskMark 8.
Nevertheless, in the case of random efficiency below CrystalDiskMark 8, the take a look at image painted no specific enchancment. This stands to purpose as elevated throughput isn’t going to assist any drive discover/search knowledge sooner.
To reiterate, this was a pre-production drive on a brand-new laptop computer slightly than our official take a look at mattress. As I needed to switch my 48GB information from SSD to SSD I omitted these outcomes. Nevertheless, 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 exams.
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 provides, slightly than the velocity of the bus. The Envoy Extremely was on tempo for a stellar consequence if it hadn’t slowed to 1.2GBps when secondary cache was exhausted.
Once more, official Envoy Extremely numbers should 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 enhance in sequential transfers — with a number of queues and with just one. On suitably quick techniques, 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.
Be aware that these exams 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 in all probability need it (we do), even when it saves you solely modest quantities of time in the actual world. Time is cash, after all, 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 nicely, and the excessive cost-to-performance ratio carries over to the Mac. Solely high-end newbies such because the Mac Mini (M4 Professional) supply Thunderbolt 5.
Lengthy story brief… For the nonce, Thunderbolt 5 is for adventurous early adopters, fanatics, and prosumers who really need the velocity, 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 bear in mind these type of compatibility points with Thunderbolt 4.
Most people will probably be simply positive with inexpensive and — for the time being — extra reliable 40Gbps Thunderbolt 4 and USB 4, together with our top-rated exterior drive, the Adata SE920.
