SSD box ORICO M2PAC3-G20 M.2 NVMe USB 3.2 Gen2x2 20 Gbps

Well, as promised, the speed has increased by 2 times.
Used a USB-PCIe(NVMe) ASMedia ASM2364 bridge. It’s not that I didn’t miss its speed, just during the last sale on 11.11, Aliexpress slipped me this lot, out of curiosity I followed the link and saw that the seller was giving out a $7/7 coupon for it, and along with the Ali coupons available in abundance, the price it turned out not much higher than on unnamed 10Gb boxes. I didn’t have much hope for success, but with it all the freezes disappeared – I repeated the test several times, there were no more problems. — buggy controller drivers (unlikely, since they were installed by Windows itself when the controller was added); Second side: I start with the synthetic test CrystalDiskMark, loved by the people for the maximum number of "parrots". Right away I check TRIM support: Recording is slightly more than 1300 MB / s, but here the SSD itself limits it, which, even when connected directly to the PCIe bus, does not give out much more – about 1450 MB / s. The tests were carried out on a computer running Windows 10 x64 with a Core i3-4160 processor and a discrete controller on the ASMedia ASM3242 mentioned above, installed in a PCI Express 3.0 slot. By the way, the same applies to the discrete USB 3.2 Gen2x2 controller – ASMedia ASM3242, released simultaneously with this bridge. For testing, I installed the fastest SSD I have, a Samsung PM981.
CrystalDiskMark: At the end there is a USB Type-C port and a speedometer icon with the number "20", indicating the speed of work: "Once is an accident, twice is a coincidence, three is a pattern." Therefore, I repeat the procedure again, without much hope of success. All further tests I carried out only with the Baseus cable. So all the offers of external SSDs or cases for them that currently exist on the market are automatically based on ASMedia products.
With SSD installed: As a result, the temperature under load did not rise above 30 °, but the freezes in the same place did not stop. The cover is installed by simply applying it from above, which greatly simplifies the organization of heat dissipation from the SSD, in contrast to the variant of cases in which the board with the SSD is pushed inward along the guides, so that the thermal interface either does not adhere to the case or sticks to the inner walls when the board is pushed in the hull from which it stretches, rolls or even breaks. There are ribs on the case that serve to improve heat dissipation from the SSD, and this measure is not in vain – fast NVMe drives are very hot.
br /> This logic is not clear to me – usually such screws are used where they want to restrict user access inside, and this device is designed for self-installation of SSD.
The maximum read speed is more than 2000 MBps – 2 times faster than a conventional external SSD on any existing USB Type-C 3.2 Gen2 10 Gbps controllers https://jiji.ng/ijebu-ode/42-room-and-parlour.

SSD box ORICO M2PAC3-G20 M.2 NVMe USB 3.2 Gen2x2 20 Gbps

– low-quality cable that comes with the case I checked the presence of the E-Mark chip in the bundled cable – it is not there. The "wonderful" company ORICO saved a few cents on a decent cable and put some junk in the kit. already once stepped on this rake mysku.club/blog/aliexpress/79047.html But there was the cheapest nameless box, and here it seems to be a decent company, so I started localizing the problem from the simplest – I took the board from the SSD out of the case and sent it to it air flow from the fan. As usual for ORICO products, this case comes in a branded white and blue box wrapped in a transparent film: Inside the box, in a plastic box, lies the case itself: The body of the SSD is steel-colored, made entirely of aluminum alloy.
Everything is in order, it is supported. My first thought is WTF.
underneath you can see a rather rich package: Now let’s move on to the actual results.
In the photo, I have already taken the C-C cable out of the bag, and the second mount is installed on the board. – buggy SSD Box (nothing to check with, because there is only one USB 3.2 Gen2x2 controller); Overview of an external SSD enclosure that supports the new 20Gb/s Hi-Speed ​​USB interface The main competitors represented by JMicron and Realtek never released their versions, apparently considering this standard to be passable and focusing immediately on USB4. It is possible that Intel’s integration of the USB 3.2 Gen2x2 controller into the 11th generation of its processors will somehow improve the situation. At the moment, this is the only chip that supports the USB 3.2 Gen2x2 (20 Gbps) standard. I send rays you know what in her direction for the time and nerves I spent.
Bought to replace an existing enclosure that I own that supports a maximum of 10Gb/s. And the choice is not very rich – from the ones I met in the news or sales: SSD Box (SSD Enclosure): ORICO M2PAC3-G20, ORICO M2PVC3-G20, SilverStone MS12, Delock External Enclosure for M.2 NVMe PCIe SSD withSuperSpeed ​​USB 20 Gbps and External SSD : WD Black P50 Game Drive, Seagate FireCuda Gaming SSD, Kingston XS2000. Unfortunately, the third time also ended with a reboot of the computer. But this is pure synthetics, but what about in practice? It ended up being ~$22. Let’s move on to measuring the speed of work. In the next steps, I still replaced the supplied type-C-type-C cable with the proven Baseus. Dimensions 106 x 39 x 12 mm. Mentally cursing all the manufacturers of computer hardware for their clumsiness, and myself for their craving for new hardware, I begin to compile a list of possible reasons:
show that everything is as promised by the seller. Board: – a buggy USB controller USB 3.2 Gen2x2 only one); – SSD overheating (unlikely, because it would just go into throttling);
This controller was introduced in mid-2019. I reboot, reformat the disk just in case, wait 5-10 minutes and run CDM again … with the same end result. The first two steps with sequential read-write went remarkably well, but on the third, with random writing in 4K blocks, the program “went into itself” for a long time, did not react to anything, and then the computer silently rebooted, which has never happened to it until now observed.
and ChipGenius: – the incompatibility of a particular SSD with this external case (you can install another of the ones I have);
including two USB cables Type-C-Type-C and Type-A -Type-C, a screwdriver, two thermal interfaces, two SSD mounts and waste paper: The results of the diagnostic programs CrystalDiskInfo:
