I have a simple three disk setup running virtualized TrueNAS with the basic 4TB WD Red disks (EFRX, replaced by EFZX this year; larger cache and supposedly a tiny bit faster). They are all about three years old (possibly longer) and running nonstop, I feel like they might be pushing their lifespan somewhat soon. Actually one of them already failed about a year ago and I had to replace it.
Lately I've been thinking about what to replace them with when their time comes, and started considering SSDs. Now I don't really know what large capacity SSDs cost besides A LOT, but quick look at the pool usage showed me I could get away with 2TB drives (RAIDz1) if I cut down on the amount of downloaded films and other questionable content.
Obviously I'd be looking at SATA drives and the speed wouldn't matter all that much as long as they are faster than HDDs; I am after faster access times etc. rather than raw speed (important, but not a priority). I don't write too much data to the thing, it's just a home NAS where I store daily backups of three PCs plus various pirated audiovisual stuff, so the endurance rating wouldn't have to be something server-grade like.
I wouldn't mind buying 2nd hand if such drive was reliable model without tons of data written to it.
So the TL;DR is: is there say 2TB SATA SSD that doesn't cost an arm and a leg when buying three of them? Obviously everyone's arm has different worth, but since this is a segment I never paid attention at, I am pretty much lost and getting some ideas is probably faster than starting a research from scratch.
edit: or should I just, when the time comes, "upgrade" to the WD Red Pro line.
