I have 2 different servers. My Problem is the SV843 is a lot faster than SM863a, what's difference between that 2 ssd? Is it just cause of that different server configs?

Server1 HP DL20 G9: 2 x Samsung SV843 480gb (MZ7WD480HMHP-00003) in Software RAID 0 mode AHCI and Windows 2016

Server2 Dell R740xd: 4 x Samsung SM863a 480gb (MZ7KM480HMHQ-00005) with PERC H730P Hardware Raid 0 and Windows 2016

Have you tried disabling read/write cache on the dell perc controller?
I have seen issues with it not being able to keep up with the io of the ssd’s
