This can drive the reported write rates even lower. Note, also, that internally all writes are in pages no matter how small a piece of data you wrote. However, if you write too much the pool of empty pages is depleted and the write stalls until a page has been erased and added to the pool. So long as you don't write too fast this process is effectively invisible to the user. The device erases those pages and moves then into the pool of writable pages. A page is taken from the pool, written and put in place of the old page which is put in a pool of pages to be erased. This is handled by actually having more memory on the device than the label says, the device has a pool of empty pages to be used for writing. Writing is fast but you can only write to an empty page and erasing is as you have discovered very slow. What is happening here is that you are seeing the erase speed of flash memory. If anyone has any other ideas about what I could try to perform a Secure Erase or if anything else could be wrong, please share this information with me. I assume the cells have been all written to for a while before I noticed this slow down ( had to reinstall windows completely a few times ), making me wonder if something else went wrong. However, these results were inconsistent which led to the conclusion that nothing had really done anything. A tool SanDisk officially recommends, HP USB Formatting Tool ( took 6 hours )Īfter performing these, the drive would be reasonably fast for the first bit after I write data to it.ATA Secure Erase Command (wasn't supported).So, I tried multiple methods in hopes of performing a "Secure Erase" on the flash drive.
I am aware that once flash memory cells have all been written to, the write speeds slow down. When writing, active time would reach 100 percent and task manager would display writing speeds between 4 kb and 100 kb. I recently noticed that my system was unusually not responding, so I check the write speeds on the drive and they have fallen dramatically. Since it was faster than my HDD, I decided to use it as an everyday booting device for Windows 10. Out of the box, it performed as advertised, with 4k r/w being really good. I purchased a SanDisk Extreme Go 64GB USB flash drive about 2 months ago.
