Lots of read and write operations that my current setup of 4xSAS15k drives in RAID10 is having made me think of a new fast storage.
My server is busy with a demanding database, lots of pages, php files and images.
So I'm considering going the SSD route (Samsung SSD 850 PRO), but with all the controversial info I'm finding on internet I can't decide if I should really go with SSD in RAID or skip the RAID and have them as "standalone".
Some say that without TRIM (as many RAID controllers doesn't have it) the endurance of the SSD's in RAID will make them wear and die in like 1 year of usage. Others say that TRIM is old news and new SSD enterprise level (Samsung 850 PROs?) disks have over-provisioning and they don't need TRIM anymore, + Samsung gives 10 year warranty to their 850 PRO's.
What are the pros and cons of 4xSSD(512Gig) in a RAID10 vs. 2xSSD(1Tb)? How long will Samsung 850 PRO's serve in RAID10?
I want to have the fastest read/writes but don't want the SSDs to die within a year, nor I want RAID controllers dying often (they say not the SSDs that die, but controllers).
