Read rates ranged between 386-406 MB/s, and write rates between 430-435 MB/s. In all five connections made directly to a Thunderbolt port on an M1 Mac, using either a USB-C or Thunderbolt 4 cable, connection speed was 5 Gb/s.

When connected to an Intel Mac using a USB-C cable, connection speed was given as 10 Gb/s, with typical read rates of 470 MB/s, and write rates of 480 MB/s. markelp and other users have reported similar results using other widely available benchmarking apps. On relatively slow SSDs, dispersion is narrow and reproducibility excellent. Results given are those for Theil-Sen regressions. If anything, that could result in overestimation of the read rate. The procedure detailed as the вЂGold StandardвЂ™ test was followed, without restarting the Mac between the write and read tests.

Transfer rates were measured using my free app Stibium, version 1.0 (55), which wrote a total of 160 files of sizes from 2 MB to 2 GB in size to a folder on the SSD being tested, and read those same files back (Series Write and Series Read Tests as detailed in StibiumвЂ™s Help reference). Again, each was verified by establishing SuperSpeed+ 10 Gb/s connections to an Intel Mac.Д¬onnection speeds were read from the SSDвЂ™s entry in the USB data given in System Information. Each was connected to an Intel Mac (including an iMac Pro) and it was verified that they established connection at SuperSpeed+ 10 Gb/s with those Macs.Д¬ables used included a certified Thunderbolt 4 model, and the USB-C (data) cables provided with the cases. In personal testing, these were mounted in basic UGREEN and similar cases claimed to be compatible with USB 3.1 Gen 2. Additional results used were obtained on other M1 models.ДЄ range of different external SSDs was used, using Crucial and Samsung SATA SSDs.

Apple MacBook Pro 16-inch, 2021 with M1 Pro, 32 GB memory, 2 TB internal SSD, using its internal display.Д«oth were running macOS 12.3.1 in Full Security mode, with no extensions which might affect USB or Thunderbolt transfer speeds.

Apple Mac Studio with M1 Max, 32 GB memory, 2 TB internal SSD, connected to an Apple Studio Display.

Personal testing was performed using two M1 models ItвЂ™s common wisdom that external USB-C devices can normally be connected to USB-C format ports, including those capable of Thunderbolt 3 or 4, using either a USB-C (data) cable, or a Thunderbolt 3 or 4 cable. In normal testing, 5 Gb/s should yield around 500 MB/s, 10 Gb/s gives around 1200 MB/s, and 20 Gb/s about 2400 MB/s. The raw transfer speeds given arenвЂ™t achieved in practice, because of encoding and other overheads.

USB 3.2 adds two-lane SuperSpeed+ at 10 and 20 Gb/s.Д¬urrently, Apple makes no claims that any ports on its M1 models support USB 3.2, only the more widespread USB 3.1 Gen 2 standard.

USB 3.1 Gen 2 adds SuperSpeed+ at 10 Gb/s.

USB 3.0 onwards supports SuperSpeed USB at 5 Gb/s.

For the purposes of this article, IвЂ™ll gloss over a lot of detail and summarise the relevant features as: Unfortunately, standards and terminology for USB 3.x are confusing. This article examines why performance experienced by users falls short of AppleвЂ™s claim.

However, many users have reported performance which doesnвЂ™t reach 10 Gb/s for directly connected external disks.

Apple claims that all its new models using M1 series chips come with Thunderbolt ports which support вЂњUSB 3.1 Gen 2 (up to 10Gb/s)вЂќ.
