I don't buy it, because it contradicts the very nature of flash storage. Unless you used your IDE HDDs as piñatas, that is. But the problems specific to SD/microSD and USB flash drives are more than limited longevity. The underlying SDIO protocol/interface of this storage type has several shortcomings making it awful for general operating system use entailing frequent intermixed writes and reads, including bringing the whole storage (and with it the OS) to a complete read-blocked freeze during extended and small rapid writes.
