XFS RAID0 Benchmarks Across Twenty SSDs vs. EXT4 & Btrfs On Ubuntu Linux

An SSD on a cheap notebook makes a lot of difference, especially at boot time. My acer aspire E1 -522 with openSUSE Leap 15 starts in 18 sec, with a mechanical HD takes almost a minute.

Hum, SSDs actually improve user experience very considerably. For me system boots in shy 6-7 seconds at most, so it powers on, rather than boots. Sometimes I even fail to see boot logo - when LCD readjusts to new video mode, its already booted, yay! Also large programs like libreoffice launch really fast. As well as all things like updating packages and so on happen in no time.

And no damn lags related to HDD seeks. Even when one lacks swap file, Linux could drop some pages of running executable files from RAM, just to read them from disk later. This eventually causes very unpleasant lag spikes since reading page from HDD can take a while. Program can't continue execution before needed page is back in memory - so one can face unpleasant lag spikes, esp. on memory pressure. SSD-based system obviously lacks this shortcoming, being very fast on things like that.

So my experience is: upgrading to SSD worth of it. Especially on Linux - where system could (and often would) be damn fast after doing so.
