My 2021 Sans Digital TR5UT+B held 5 SATA disks. I had an eSATA
connection to the host box. It went belly-up a few weeks ago.
After some careful searching, a good replacement seemed to be the Oyen
Digital Mobius 3R5-EB3-M. Found it for about $300USD.
It was plug-and-play replace. Drives were being addressed by UUID in
Fedora so no issues at all. It came right up.
However, smart reporting looks horrible even compared to the TR5UT+B
(which had its own issues).
Here's what the TR5UT+B (old cabinet) reported for one disk in the
unit (just the header section of smartctl -a):
=== START OF INFORMATION SECTION ===
Model Family: Western Digital Red
Device Model: WDC WD20EFRX-68EUZN0
Serial Number: WD-WCC4M6HX8XCR
Firmware Version: 0957
User Capacity: 2,000,398,934,016 bytes [2.00 TB]
Sector Size: 512 bytes logical/physical
Device is: In smartctl database [for details use: -P show]
Here's what the Mobius reports now for the same disk:
=== START OF INFORMATION SECTION ===
Device Model: Mobius DISK1
Serial Number: WD-WCC4M6HX8XCR
Firmware Version: 0962
User Capacity: 2,000,398,934,016 bytes [2.00 TB]
Sector Size: 512 bytes logical/physical
Device is: Not in smartctl database [for details use: -P showall]
The disk model is gone. The firmware version is wrong (cabinet instead
of disk?!). I imagine firmware updates are impossible here.
The rest of it is unimpressive, too. No SCT (TLER) at all - not just
ERC, but SCT Status, SCT Feature Control, SCT Data Table are all
missing too.
All the disks in the cabinet are WD20EFRX-68EUZN0. So I believe they
have SCT/TLER.
What RAID cabinets would be a better alternative? I have 5 drives but
an 8-bay cabinet would work too.
Obviously, SMART pass-through would be 'nice'. But so would SCT (ERC).
