The Al-Enclosure is properly crafted, but the the electronic Board is not designed for full Thunderbolt 3 operation. The PC-Board is marked "1947" & "AR-SP-NGFF_Rev1p0". This is a clear indication, that only outdated M.2 SSD will work in the "FA-TB34". For the current M.2 MVMe SSDs the Intel bridge chip is outdated (relese. 2016) and can not deliver the necessary current for 2019-type SSDs like AN3 or 970EVOPlus. Furthermore the previous M.2 NVMe SSDs are available only up to 1TB. It is not satisfactory to use an outdated Enclosure with reduced write and read speed and the limitation to be restricted to 1TB. (The write speed of a 970EVOPlus 1TB is less than 900MB/s - not even equal as it would be in a UBS-C Enclosure with average W/R of 940MB/s.
