You can't tell. The interface doesn't have any way to figure it out. They don't even support SMART.So how do I tell which flash chips are used in any particular stick and which would you recommend?
And can you tell how may 'write cycles' have taken place. I could do with going through all mine to see may be on their way out, if that's possible...
zpaqfranz v51.28-experimental snapshot archiver, compiled May 28 2021
franz:VERBOSE list of files on (-verbose)
franz:KILL!
This is FILLAMI, reliability test for media.
Almost all free space will be filled by pseudorandom 512MB files,
then checked from the ztempdir-created folder.
These activities can reduce the media life,
especially for solid state drives and if repeated several times.
Normally used as stress test for newly devices/controllers
or (via NIC) for heavy network stress test.
Temporary files are NOT deleted by default (for zfs's scrub).
-kill switch will clear (delete) temp files after execution
-verbose for extended output (check IO consistency speed)
More than 2GB of free disk space needed.

all that trash
Basically I have a dodgy disk which is painfully slow and want to quantify just how painfully slow it is.Throw all that trash out and use the tools in base.dd
files to it and monitor that withgstat
orvmstat iostat
.
That is true random sequential.
Ok 'trash' might have been an Oko like response.I found stressdisk useful on more than one occasion.
dd if=/dev/random of=/dev/da0
?… couldn't you stress the disk withdd if=/dev/random of=/dev/da0
?
stressdisk cycle /media/General_UDisk_/
very soon yields an error (no surprise, given the low quality):% stressdisk cycle /media/General_UDisk_/

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 1 occurred at disk power-on lifetime: 4412 hours (183 days + 20 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
ER ST SC SN CL CH DH

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
Can anyone make anything out of the output I get from smartctl ?
