Just purchased this Sn850x 8tb 2280 installed in a 40gbps Enclosure w/ genuine thunderbolt 4 cable. And I got it for coding/ programming BMW modules/ diagnosed BMW cars. I can’t understand why my tranfer speeds are 100 mbps at times.
First picture is the WD Black SN850x 8tb in. 40gbps enclosure with a genuine Apple thunderbolt 4 cable.
Second picture is the SSD that is on the hard drive of the laptop
Lenovo yoga7i 16IRL8 1tb
Thunderbolt is slower than PCIe x4 slots so do not expect miracles.
If you need more storage M.2 NVMe SSD in the M.2 2280 format reach 8TB at present
