I formatted a--very--cheap 1 TB SD card to NTSC and it took > 2 days. I then copied a 19 GB file on it and the 1st ~3/5 it was at ~3.5 MB/s and the remainder seemed to increase ~1 MB/s. I then did a checksum on it and I didn't realize I was doing 2 at the same time, I sent the file to Jacksum and I saw no message, no progress bar, heard no sound, so assumed the program didn't work, I then started a checksum with a GUI, and it took a looong time to complete, well it turns out the Jacksum result was about the same time as the GUI as I kept a semi-regular eye on the GUI (and Jacksum put its result in a new Notepad instance) ; the speed seemed to be about the reverse, it started slow for a long time then it got ~1/3 slower for some time.
Now I've been running h2testw for 2:30 and it got to 34 GB and it's been writing at about the same speed as the earlier 1st part (~3.5 MB/s ). I expected the writing to stop <= 19 GB. Is it going to stop if it's a fake SD that's set to loop until it get to 1 TB or not? If not, I have to wait the almost 3 days predicted to remain if it keep about the same speed to then read in a loop for who knows how long, probably 2X as long if the experience matched my earlier test of 19 GB, to find out h2testw write doesn't match it's read ?
Thank you kindly for your help
