>it was quick-formatted

are there OSes that perform quick format without issuing TRIM command to the SSD? TRIM would vanish the data in less than 15 minutes.

Yes, 15 minutes is not 'quick' by most standards - quick formats take seconds, not minutes.

up to ~15 minutes is not the time it takes to quick format, its the number Iv seen during testing of TRIM, the time it took to internally erase translation table after format command.

There should be NO DATA on the drive if it was really formatted on OS supporting TRIM.

I believe parted won't issue TRIM for whole disk/partition after erasing partition table or partition. Possibly mkfs.xfs issues TRIM? I don't know.

Anyway, what they should at least is just issue `blkdiscard /dev/sdb`, or betterly Secure Erase (on SATA) or Sanitize (on NVMe).
