Raid still exists and are heavily used for large sata storage pools to avoid data loss in disc crash

SD cards are extremely slow, so they're the last thing you want to have your OS on. SSDs are much more suitable. And SSDs are also making their way into laptops; faster, quieter, cooler, sudden movements of the laptop can no longer harm the moving parts of the disc etc. But many producers of laptops seems to think that a pc with 700GB will sound better in the ads than one with 240GB; SSDs are much more expensive.
Besides they can wear out. The technology behind nand flash sets a limit to how many writes you can perform on your drive. After about 30000 write cycles the disc is useless; if you have a 100GB disc, you can "only" write 3000TB to your drive before it is worn out. 3000 TB is a lot, but if you, like me, produces a lot of computergenerated files, analyzing the results in automated scripts, and deletes the files again, you could theoretically wear out an SSD. ( Yes I know, 3000 TB is almost 1TB each day for nine years, but still it's possible, though admittedly farfetched).
