SATA SSDs last a long time, yes.

I'd imagine OP is actually talking about NVMe though, which does NOT - or at least not on the scale of old SSDs.

I have put more than a couple NVMes in the ewaste bin over the last few years.

We buy and use them for the performance though - and I for one want the web to feel snappy, so while it could be read/write heavy, no way I'd be moving the cache off my fastest disk.
