7 The days of shitty JMicron stuff and OCZ drives dropping like flies are
8 long gone... you are not going to encounter write endurance problems
9 with a modern SSD from a reputable brand and any kind of reasonable
10 workload. Stay clear from QLC drives and you'll be fine.

12 I have a laptop with a 256GB Plextor M5M SSD installed in 2014. I dual
13 boot Gentoo and Windows, and in addition to the normal stuff, on the
14 Gentoo side I do a couple of world updates per week -- which with a full
15 KDE desktop involves quite a bit of compiling and writing around.
16
17 The SSD is currently reporting 98% of its rated life left: I feel quite
18 confident it's going to outlast the laptop's useful life.

20 That's not a single datapoint; every system I have around has used an
21 SSD as a primary disk for years now, and I've yet to see one fail or
22 develop any kind of corruption issue. In the same timespan I've had a
23 fair number of HDD failures.

33 It will probably work, if you hack at it long enough :D
34
35 But seriously, what's the point? Setting up a patchwork of a filesystem
36 like that and maintaining it in time is going to be a complexity and
37 reliability nightmare: if you're going to those lengths because you
38 don't trust SSDs, why have an SSD at all?
