Orico Montage MTQ 40G Review4

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

I have previously covered the confusing mess of names for USB and the differences between USB4 vs USB 3.2 Gen 2.

Technically, USB4 can be 20Gbps for USB4 Gen 2×2, which is also the same speed as USB 3.2 Gen 2×2, even though there are differences between the two.

However, I wanted to find an enclosure for an NVMe drive that would provide the best speeds possible.

I previously reviewed the Sabrent EC-SNVE, which is only 10Gbps with USB 3.2 Gen 2×1. With a PCIe 3.0 drive has speeds up to 3500MB/s or 28000 Mbps. So if you want the fastest external storage possible, you need a USB4 SSD or to install an NVMe drive into a USB4 enclosure.

With a PCIe 4.0 x4 NVMe drive such as the FURY Renegade or the KC3000 you have read/write speeds of around 7,000/7,000MB/s or 56000Mbps. However, from what I can tell, USB4 enclosures don’t support PCIe 4.0

I have also reviewed the excellent Orico Montage MTQ-40G external SSD, which was the first USB4 SSD to launch, and it has read speeds rated as up to 3,126MB/s. I was able to achieve 3,340MB/s for sequential reads and nearly 2000MB/s for writes.

If you would prefer to use your own NVMe drive, then there are several USB4 enclosures available on Amazon. However, it would appear that some are advertised as USB4 but are, in fact, Thunderbolt, so you need to be careful about what you pick.

Best 40Gbps USB4 NVMe Enclosures

Acasis TBU401

Acasis TBU401 40Gbps M.2 NVMe Enclosure

This USB4 enclosure appears to be the best all around option. It is the most affordable choice on Amazon, and it has the best reviews.

The is a toolless enclosure that is compatible with M-key 2280 drives. There is an included thermal pad to reduce thermal throttling.

Acasis TBU401 1

The description states that this is not compatible with Samsung 970 EVO Plus SSD, SN850 and iPad. Not recommended ADATA, CRUCIAL, and other non-mainstream SSDs.

Their own test reports state that the WD Black SN850 has transfer speeds of 2717MB/s read and 2748MB/s write. Some user reviews report speeds of up to 3000MB/s for some drives.

A lot of users seem to buy this for the Mac M1 or M2, though that will be using Thunderbolt.

Acasis TBU401 3

ORICO 40Gbps M.2 NVMe SSD Enclosure

About the same price as the Acasis, but less positive reviews. Reviews criticise the build quality and suggest it should have been an aluminium housing.

One reviewer suggested this is one of the best options to buy because it uses the Realtek RTL9210 controller, which is superior to the Jmicron or AMS controller.

This model confirms it is also compatible with Thunderbolt3/4, USB3.2/3.1/3.0 interfaces.

USB4 Enclosures that I do NOT recommend

There are a few enclosures on Amazon that are listed as being compatible with USB4, but reviews and even product descriptions indicate this may not be the case.

These products are Thunderbolt 3, which is not the same as USB4, and therefore, you may not get the 40Gbps throughput USB4 is capable of. Many of the good reviews these drives get are from people using them with Macs and, therefore, Thunderbolt.

Yottamaster USB4 NVMe Enclosure

This has basically the same specification as the Acasis, but the reviews are not as positive.

I am not specifically recommending this one because user reviews suggest it may not be USB4 at all.

It works with Thunderbolt 3 (40Gbps) and USB 3.1 Gen2 (10Gbps) modes and may not even support USB 3.2 Gen2x2 mode (20Gbps).

The controllers used are JH7440 and JMS583. JHL7440 is a Thunderbolt 3 controller (40Gbps), while JMS583 supports up to USB 3.1 Gen2 (10Gbps). JHL7440, while supporting 40Gbps, is a Thunderbolt 3, not USB4/Thunderbolt 4, controller.

Yottamaster USB4(40Gbps) NVMe Enclosure

Same brand as above, but different enclosure, I would guess it is the same hardware inside.

This model appears well-reviewed, but the reviews are all for the other enclosures models on that page, not the USB4.

It is listed at £140, but when I checked the Amazon page, there was a 20% off voucher taking it down to £112, which is about the same as the other enclosures I have listed.

This is an aluminium enclosure with a heatsink, so it hopefully has better cooling than the ORICO.

This is the cheapest option I could find. This model confirms it uses the JHL7440 chip, but as mentioned above, that’s a Thunderbolt controller, not USB4.
