RAID 0 with 2* Samsung 850 PRO 256GB or 4*Samsung 750 EVO 250GB ?

[Gartix]

So guys here it is:
Solution with 4 SSD its just 20 eur more expensive but should be twice faster around (IT REALLY WILL ???)
BUT- im not sure if I will sacriface 10 years warranty in 850 PRO and instead of this get just 3 years at EVO SSD, so do you think its really that big different between lifetime of EVO and PRO version,like their warranty has ?!?

Only really faster thing would be sequential R&W and that's the part that counts least. SATA gets maxed out with RAID0 on SSDs so it can't be much faster and problems are more common.

RAID 0 + SSD. Read this all the way through before you go down that road:

" but should be twice faster around"
No, it won't.

Thanks guys,BTW this review was what I was looking for! I was also think that even if I will dont use raid 0,anyway I will get 2 SSD one for system and apps and secound one for video material,but I think is also wasting money,I will go for 850 Pro 512 GB,I think I will survive with this so far.....

2 drives is fine. In fact, recommended.
I currently have 4 x SSD in my main system
1. OS and applications
2. photo and video work
3. games and doc/music
4. scratch space for Adobe Lightroom and video editing applications.

5. 3TB HDD for backups.

Hmm,then I will inspire by you and I will place order for one 256GB 850 Pro for OS and apps and one 500 gb SAMSUNG MZ-75E500B for other stuffs . thumb up guys! there will be also 3TB WD red,and already I have 3TB extern HDD samsung...thats should be enought.

Mate, l can share my real experience based on slightly different system:

l recently upgraded a GT80 notebook from 2 x m.2 128 Gb (original and unusual brand) to 4 x M.2 500Gb 850 EVO. At a first step, l installed 2 of the 850 EVO in the 2 empty slots l had, l got between 800 and 900 MBps for both read and write (ATTO benchmark ). After that, l put all 4 x 850 EVO in Raid 0 and l got a consistent 1350 MBps for writing and 1650 MBps for reading (file size above 4MB).

Undoubtly, what l could observe is, in my notebook (i7 5700 , 16gb ddr3) , with more bottlenecks than a modern desktop system, there is an almost linear gain in both read and write speed if you upgrade from 2 to 4 Samsung EVO SSDs in raid 0.

Based on theoretical info from internet, 1 Samsung PRO SSD delivers about 520 MBps and so, 2 Samsung PROs SSDs in raid 0 will no way deliver you 1650 MBps for reading / 1350 MBps writing, and so you can already conclude that 4 x EVOs are much faster than 2 x PROs (unless you have a pretty much old CPU - intem pentium .... - that will act as the bottleneck of your system).

PS: consider all drives on sata 3 interface. Samsung SSDs based on PCIE 3 are much much faster drives.
