~8GB, `lsblk` reports 7796176 * 1KB = 7983284224 bytes.

We got a handful of those from <École Polytechnique> at the end of studies I think.

They are shaped like https://en.wikipedia.org/wiki/Bicorne[bicornes], which is super cool, but also super impractical!

Markings: "AX ÉCOLE POLYTECHNIQUE PROMOTION X2009"

20.04 `gnome-disks` program reports it as: "SMI USB DISK".

From <Ubuntu> 20.04 on an ext4 formatted one:
``
/dev/sdb:
 Timing cached reads:   28656 MB in  1.99 seconds = 14421.31 MB/sec
SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
 Timing buffered disk reads:  42 MB in  3.03 seconds =  13.88 MB/sec
``
With <Linux Unified Key Setup> + ext4 the results are similar, maybe hdparam bypasses it?
``
/dev/sdb:
 Timing cached reads:   28326 MB in  1.99 seconds = 14251.55 MB/sec
SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
 Timing buffered disk reads:  38 MB in  3.11 seconds =  12.23 MB/sec
``
`gnome-disks` LUKS + ext4 benchmark with default params also gives about 14 MB/s.
