In regular hard drives and SSD's, they have FEC chips or equivalent (forward error correction) so whenever the platters return a bit error, that error should be noticed and the corrupt data should not reach the OS.
I have seen many times, USB and SD cards start silently returning corrupt data. You waste a bunch of time figuring out where corrupt data is coming from, and then discover that if you literally read the same file from the USB drive more than once, it comes out differently. So you throw out the USB drive, and wish you could get your data back. (And the last several hours you spent debugging). The usual filesystems that you use on USB drives don't have data integrity built-in, and that's not going to change anytime soon, so I am hoping to find some kind of higher quality USB flash drives, that actually provide data integrity, such as ECC ram does, but I haven't found a good search term yet. Any suggestions? I've tried USB Flash Drive Error Correction, error detection, fec, ecc, data integrity... So far all I've found is this (found by searching for USB Flash Drive ECC): http://eflash.apacerus.com/spec/USB/Drive/Industrial-USB3.0_EH353.pdf They have a whitepaper indicating ECC and EDC. When I search for those, they're not sold at the usual vendors like amazon, newegg, bestbuy. They're sold by mouser, digikey, etc. They're called "industrial." And honestly, the prices are not crazy. So I'm probably buying some of these today, but I'm trying to learn something here, and figure out how I can consistently find good drives in the future. Anyone know anything?
