Beggar Edition mac mini 256g
Want to install external macos on ssd, the hard disk box is tentatively Akasis
The ssd is tangled between sn770 and sn850x.
More people use sn770. I'm a little worried about the heating of the sn850x affecting the stability. However, the sn850x speed is higher. If the hard disk box is updated in the future, macos can get higher read and write speed
Has anyone used SN850X plug-in macos?

Poster Jun 16, 2024@ Anonymous3412 The hard disk box is planned to use Akasis TBU405ProM1, Thunderbolt interface, which can support 2000 + MB/s Weibo has an internal test of the next generation Akasis with sn850x, and the speed can reach 6000 + MB/s

Anonymous3412 Jun 16, 2024Fix 2 #, wrong calculation The 20Gbps of USB3.2 gen2x2 is roughly 2500MB/s. But if you calculate carefully, according to the 64/66 encoding system of USB4-20Gbps, it is actually 2424MB/s, and USB4-40Gbps is 4848MB/s. In terms of TB, although the total bandwidth is 40Gbps, the maximum data actually supplied to the DP link is 32Gbps, which is the level of PCIe 3.0 x4.

Anonymous2154 Jun 16, 2024@ Poster suggests buying a cheap one first. When the next generation becomes popular, it will be time for what you use now to break. Maybe you can change it to a better one when the time comes.
