When transferring large files between two SSDs the transfer speed goes from high 400's MB/s down to 17-20MB/s. I understand there is a cache but I feel like those are USB speeds, not internal SSDs ones. I have enabled write cache, and even set my pc to high performance power mode. Both SSDs are connected internally via SATA III 6G.
I am transferring the data between
  • Samsung 860 EVO 1tb ( MZ-76E1T0B/AM)
  • Silicon Power 1TB SSD 3D NAND A55 (SP001TBSS3A55S25)
If it matters... my PC specs are...
  • Motherboard - ASUS Z170-A
  • CPU - I7 - 6700K
  • Memory - G.SKILL Ripjaws V Series 64GB DDR4 3200 (PC4 25600)
