How to choose a good SSD for a server, from 200 to 500 GB and more than 1000 TBW?

Question

Solid State Drives

There is a server with RAID-1 from two HDD on 1TB. You need to move the system and database to an SSD. The question arose of choosing a disk, of course, on order (in my region this is not available in stores). What disk would you recommend, so that the read speed is from 500 and the write speed is not lower than 350, and most importantly, that it is very reliable, because. here, neither service centers nor warranty service simply exist within a radius of 3000 km?

Answer 1

Take two or three SSDs, by the way, it is not necessary to do a raid, especially if you survive the loss of the last minutes in data (you can replicate the database to a nearby cheap server instead of a raid, with slow disks, if their speed is not enough, set up replication is not real time), sometimes a drive lying in a cabinet (or in the same server, not connected), ready for a quick replacement of a breakdown, a huge bonus, especially if you have 'distant ebony'
Some budget savings are possible (take less volume) if you do not transfer the entire database to ssd make it a cache for hdd in a hybrid scheme (all linux somehow have free tools for this, and windows are paid).
those. it turns out that instead of an expensive server half-byte, you take two / three desktop 128-256, and make software settings.
ps do not keep the system in the same place as the database.
