Thank you. That is interesting.Pny cs3030, which I have, does something similar

PNY XLR8 CS3030 NVMe SSD review: Cheap and exceptionally fast for everyday chores
PNY's CS3030 NVMe SSD is a great everyday performer. For the average user, it's a bargain, but it slows more than usual for a bargain drive during long writes.www.pcworld.com
It can write zeros all day long at 1.7GBs but random is a lot slower.
dd if=/dev/zero of=/dev/nvme0n1_of_cs3030 bs=4M count=12000
dd if=/mnt/Xtmpfs/random_48GiB of=/dev/nvme0n1_of_cs3030 bs=4M count=12000
Technically an update to the metadata is a write to the media, and in my experience "technically" is how SSD makers like to follow the specs, that's how some of those Sandforce drives could lose 20+MB of data which had successfully been fsync'd on power loss. The spec said they could return the fsync command when the data had been written durably, but, because at that time it was written with just spinning disks in mind, it did not explicitly require that the metadata required to read the data back must be written durably, so after reboot you would read back zeros or older version of the pages. Even Intel played that game, to a lesser extent, until they added PLP in the third gen drives.[Specifications (ATA & NVMe) dictate that a WRITE (device cmd) results in a write to the media.]
A generic piece of advice for torrenting drives is they are subject to a ton of random write activity.should I use these for torrenting(random read/write)? I'm downloading and uploading 24/7 with 10-20 torrents active at the same time
my speed is 500/200, or should I stick with HDDs?
ZR11RPA1 for this ( ECO Gen II 1.9TB)There seem to be several firmwares on the wd zip file, how should I choose the correct one?
I used their CLI on Linux; straightforward, no problemo.3. Update the firmware. Here is where I'd like input from someone who has actually updated it.
Updated 4 drives using ubuntu without problem with these commands. One drive was on ZR01, two on ZR04 and the last one on ZR07. All completed without errors using a sata to usb sabrent adapter. From Windows (using the same adapter) was impossible to get the drives detected.I've tried the windows app as described, but failed miserably, again. Then succeeded with the linux version with a little trick:
./scli update /dev/sdb -p ZR09RPA1_w_boot_BLR-0080_QR.dob -m dnld-wo -l 1
./scli update /dev/sdb -m activate
./scli update /dev/sdb -f -p ZR11RPA1_w_boot_BLR-0080_QR.dob -m dnld-wo
./scli update /dev/sdb -m activate
I found that doing separate download + activate worked well if I've used the older firmware first. Using ZR11PA1 straight from ZR03PA didn't worked.
Hooray for Linux.Updated 4 drives using ubuntu without problem with these commands. One drive was on ZR01, two on ZR04 and the last one on ZR07. All completed without errors using a sata to usb sabrent adapter. From Windows (using the same adapter) was impossible to get the drives detected.
