Beginners • RPI4 - USB - M2-SSD

try new OS Debian Trixie
on hardware:

• RPI 4B
  ORICO TCM2-C3 - NVMe M.2 SSD ENCLOSURE (10Gbps) (RED)
  WD_BLACK SN770 250GB

test from PC USB 3.1 _____ 420.86 MB/sec
test from RPI4 USB 3.0 ___ 312.47 MB/sec
test RPI4 uSD shows ______ 40.17 MB/sec

but orico 'cooler' get very hot
and VNC RPI4 desktop freeze
and file problems like
file delete / reinstall / see directories but not the files / ???

but after full burn from uSD again it looks ok

so if the SSD is bad i need a new one ( it actually was a new, free one as a WD warranty replacement ),

or if it is good, but stops working in that adapter because of heat?
what can i do?

my understanding is that SN770 is a PCIe4
but that might be no use if connected to USB 3.0 anyhow ?
could it be better to buy a PCIe3 M2 SSD ? might that REDUCE the heat ?
