I am sorry, I wasn't sure where to post exactly.
I operate a dedicated server with a Xeon E3-1245 (v2) CPU and 3 x 120 GB SSD.
I am about to reinstall my server completely, and switch to Debian 9. I am also taking the opportunity to refine the way I am managing data, and sort/optimize several things.
So far I was NOT in RAID, because initially my data were bigger. Actually, all my data + OS are taking "only" 169 GB.
So I am wondering if setting the 3 SSD in RAID 5 (Software), would be a good idea or not. This would be roughly 240 GB of space, which I think is leaving enough margin to see things coming, considering my data are not increasing quickly.
I was wondering if the "reading" of data from a RAID 5 Soft will be at least as good as without RAID? (90% of operations on my server are reading, and most are ending in memory cache) In other words, can I expect at least the same performance in reading , as in my actual set up, with no RAID. I think this is what I understood, but I am seeking confirmation (or not).
