What speeds should I expect from SATA hard-drive transfers?

[Baddass]

I have the following two hard drives in the same system, but wanted to sanity check what transfer speeds i should expect when copying and pasting content between the two:

Samsung 250GB 860 EVO SSD 2.5" SATA 6Gbps 64 Layer 3D V-NAND Solid State Drive (MZ-76E250B/EU) -

Western Digital Caviar Green 1TB SATA 6Gb/s 64MB Cache - OEM (WD10EZRX) **SINGLE PLATTER** HDD


When copying a 4Gb file from one to the other i'm getting speeds of about 120 MB/s, is there a way to improve this?

thanks guys, i just wasn't sure if that was a reasonable transfer rate between those two. appreciate the replies
