Bought December 2023 for 300 pounds, so 15 pounds / TB. Needs power supply unfrotunately besides USB, the largest one without needing power supply was only 5 TB at the time so not worth it, given that my P14s alreay carriers 2 TB. 10x is a must for the external crap.
Noise: it has a constant pleasant hum, with a not so nice click every 5 seconds or so. Reasonable, but not amazingly incredible.
The size is reasonable, not megaportable, but definitely reasonable.
~1TB.
Internal hard drive likely removed from some old computer I lost track of, kept in a crappy case, incredible stuff.
Ubuntu 20.04 gnome-disks benchmark, NTFS partition: 40MB/s.
~1TB.
Has a separate power cord, not USB powered. Unbelievable. Edit: actually high ends are still like that as of 2023, e.g. at that time, a the max non-cabled was 5 TB, but top of line was 20 TB.
Disk label: wd1t.
Ubuntu 20.04 gnome-disks benchmark, ext4 partition: 37MB/s.
Marked read speeds up to 150 MB/s
Write speed burning 5 GB Ubuntu ISO from Dell Inspiron 15: 5.4 MB/s
For clean Dell Inspiron 15 3520 cryptocurrenty laptop bootstrap and backup.
~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 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.
