single big ssd vs a few smaller ones

[bug]

No, constantly writing to an SSD (particularly one that's rather full,) is the worst thing you can do to it.

Also tell that to my >7 year old SSD SATA RAID in RAID-0. It's still going strong after all of these years. Also FWIW, at the time, two 120GBs was considerably cheaper than a single 240 when I bought them, so cost was a motivating factor.

I meant it's a lot of fuss with nothing to show for. RAID0 only increases sequential r/w, but doesn't improve 4k random reads in any way. Plus, as reliable as SSDs are, if one drive fails, you still lose the content of both.
