It was a bit rough around the edges in terms of in reverse compatibility, my very first appearance at 80Gbps Thunderbolt 5 storage exposes an extremely good uptick in efficiency– about two times the 40Gbps of Thunderbolt 3/USB 4 in particular criteria. Sensible.
By method of contrast, that’s approximately as quick as an NVMe SSD on the PCIe 4.0 bus. And a PCIe 4.0 NVMe SSD is precisely what’s inside the OWC Envoy Ultra portable drive I utilized to check Thunderbolt 5 storage.
Keep in mind that you’ll see 120Gbps noted in the Thunderbolt 5 specifications, however that’s uni-directional output for driving numerous high-resolution display screens. Bi-directional transfers such as those utilized by storage gadgets are “restricted” to 80Gbps, or approximately 6- to 7GBps after overhead.
How well does Thunderbolt 5 work?

My launching take a look at Thunderbolt 5 came thanks to the previously mentioned Envoy Ultra connected to a Thunderbolt 5, 32GB Maingear ML-17 (Mk. II) laptop computer. Undoubtedly, I wasn’t able to utilize the 59GB RAM disk in my basic test PC for 48GB transfers, however the T-Force NVMe SSD in the laptop computer offered a decently quick alternative.
Sadly, the Envoy Ultra totally stopped working to appear on our main Asus ROG Strix Z790-I (Thunderbolt 4) test bed. It didn’t appear in the BIOS, disk supervisor, or the Thunderbolt energy. The concern is being cooperatively examined by OWC, Intel, and Asus as the drive stopped working to specify on an Asus Maximus Z890 Hero board. In case you weren’t mindful, Thunderbolt 5 is expected to be complete backwards suitable with variations 3 and 4.
Even more, just the more recent Sonoma and Sequoia variations of macOS would acknowledge the Envoy Ultra for usage on my Apple Silicon Mac Studio, though it was mentioned on the Thunderbolt bus in System Info as far back as Ventura. Sequoia is needed for Intel-based Macs.
I was not able to check on older Thunderbolt 2 systems as the Envoy Ultra sports a captive Type-C cable television which avoided me from using Apple’s Thunderbolt 2 to 3 adapter.
This is a very little sample size of devices, so I’m unsure simply how prevalent the problems are, however there have actually been rumblings around the market about the existing state of compatibility. It’s certainly toe-in-water-time for Thunderbolt 5– even for early adopters.
Keep in mind that after a Z790-I BIOS upgrade (9901) supplied by Asus on November 25th, 2024, the Envoy Ultra was acknowledged and carried out as anticipated.

What Thunderbolt 5 equipment is readily available?
Another Thunderbolt 5 laptop computer presently shipping is the Razer Blade 18. Both Asus and Gigabyte have actually revealed a multitude of motherboards that either function Thunderbolt 5 or sport headers so they can be updated to it by means of add-on cards.
Can you update older computer systems with add-on cards? According to my queries, no. There are some creative engineers and hackers out there, however there are timing concerns and other aspects that make porting in reverse extremely not likely. Yup, you’ll require brand-new things to get Thunderbolt 5 speeds. And note that neither Thunderbolt 4 or 5 work with older Thunderbolt 2.
How about 6GBps consecutive reading, and almost 4GBps consecutive composing with several lines? There’s almost 4GBps consecutive reading and composing single-queued. That’s a really good bump up from the previous highs of around 3GBps multi-queued and 2.5 GBps single-queued provided by 40Gbps USB 4.
It’s about what we ‘d get out of doubling bandwidth from 40Gbps to 80Gbps. You can see the proof listed below from CrystalDiskMark 8.
When it comes to random efficiency under CrystalDiskMark 8, the test photo painted no specific enhancement. This stands to factor as increased throughput isn’t going to assist any drive find/seek information much faster.
To restate, this was a pre-production drive on a new laptop computer instead of our main test bed. As I needed to move my 48GB files from SSD to SSD I left out those outcomes. In overall with this plan the Envoy Ultra still completed a simple 2nd slower than the very first location OWC 1M2– quickly within the margin of mistake for these tests.
We likewise left out the outcomes for our normal 450GB compose as it’s more a test of the SSD inside and the quantity of secondary cache it uses, instead of the speed of the bus. The Envoy Ultra was on rate for an outstanding outcome if it had not slowed to 1.2 GBps when secondary cache was tired.
Once again, main Envoy Ultra numbers will need to wait till we update our test bed to Thunderbolt 5. The test results above are merely to highlight the rough distinction in between Thunderbolt 3/4, USB 4, 10Gbps USB, and Thunderbolt 5 efficiency.
In summation, there was a significant boost in consecutive transfers– with numerous lines and with just one. On appropriately quick systems, it must conserve you time. When once again, random ops are minimally enhanced so do not anticipate an uptick in lots-of-small-files circumstances.
Keep in mind that these tests were worked on a pre-production variation of the Envoy Ultra, though OWC did ultimately get a shipping variation to us.
What does Thunderbolt 5 imply for you?
Thunderbolt 5 is here and you most likely desire it (we do), even if it conserves you just modest quantities of time in the real life. Time is cash, obviously, however to see an earnings, you’ll need to get rid of some substantial preliminary financial investments– the 2TB OWC Envoy Ultra I checked is $400 and the 4TB is $600. Gulp.
Thunderbolt 5 motherboards and Windows laptop computers are priced for the top-shelf too, and the high cost-to-performance ratio rollovers to the Mac. Just high-end newbies such as the deal Thunderbolt 5.
Long story brief … For the nonce, Thunderbolt 5 is for daring early adopters, lovers, and prosumers who really require the speed, and have the software application and hardware to benefit from it. This is foregone conclusion with any brand-new innovation, though we do not keep in mind these sort of compatibility problems with Thunderbolt 4.
Many folks will be simply great with cheaper and– at the minute– more credible 40Gbps Thunderbolt 4 and USB 4, including our premier external drive, the Adata SE920
