Yes, around the same results. Out of curosity could what SATA port my HDD is in matter? like I my SSD in 1, HDD in 2 and a dvd-rom in 3.

Update: I moved the SSD from SATA port 1 to 4, didn't notice much of a diff, going to have to buy/get a new cable and see if thats the issue as I have no spare ones.

Update 2: Seems I had a Sata 6g cable inside my motherboard box that was brand new, put it back to port 1 with the new cable, but same write performance, so its either my mobo, or the ssd itself. Marking this as solved as I don't think there is anything else I can try that I know of other than getting a new ssd entirely and seeing if it has the same problem.

Thanks for the help everyone.

Just thought I'd let ya know I got a new ssd a Samsung 860 Evo 500 gb, the write speed issues was my old Sandisk SSD Plus, it was either defective or just had plain crappy write speeds period. At least now I am happy to know it wasn't the sata cable or more importantly a problem with my motherboard, it was the old ssd itself.

Maybe a faulty DRAM cache? When they get saturated the sequential write speeds can drop off a cliff on the cheaper drives.
It's generally one of the main improvements with the better performing SSD's like the Samsungs et al.

Although I've got a Sandisk extreme 11 SSD 'C' drive and it's a very good performer, no issues at all.
