Thank you for the tip, I'll consider these in the future too. I've found Intel 35xx/37xx series to be the other option of better flash drives currently on the market. Yet, it's still not the same class of reliability. This is not related to OpenBSD, but my 20+ years of hard disks are still able to store and retrieve data, after their long and useful production life. I can not validate this for any other flash or memory based storage device. In present understanding data retention decay is still present in the flash devices and can not meet spinning hard disks, and we all know that's not going to change without improvement in battery ageing and the type of cells used in the flash drives. I insist on recommending pairing any storage type device in soft-RAID and not mixing device types in the same array, advising the reliable parts despite hating the enterprise server tax for personal use. This and advanced engineering knowledge on the basis of technical specifications and hardware documentation, to compliment the incredibly useful OpenBSD software man pages and source code. For kids: don't forget to make a copy of your important files.
