Hello, Last week i did a upgrade on my Inspiron 15R SE(7520) with a SSD Samsung EVO 850 500GB, and now i'm intending to buy one msata Samsung EVO 850 500GB, But i would like to do a RAID 0 with those two "drives", So is that possible? Will it work and have a gain of performance?
Sorry for my bad english, i'm still learning.
My Specs (Inspiron 15R SE (7520)
Intel Core i7 3632QM
8GB ram 1600Mhz
Primary: SSD Samsung EVO 850 500GB
msata: 32GB MZMPC032HBCD
Secondary: Seagate ST1000LM024 5400RPM 1TB
It's not going to gain you anything, no. One SSD will easily outrun the ability of the SATA controller in speed - all you'll do is double your chances of data loss (since the data is striped over two drives, if either fails, you lose everything).
So what is the difference of perfomance between a RAID 0 of 2 SSDs EVO 850 and a RAID 0 of a mSata EVO 850 + SSD EVO 850?
There won't be any difference -- a single drive will easily deliver the 6G/s that a SATA interface can handle.
