Hi Guys, I've been setting up my XPEnology for the past few weeks and noticed that my write speeds went down horribly after enabling SSD-cache. The transfer starts out at about 1GByte/s (not bit) but goes down all the way to 30MB/s or even lower write speeds, read speeds are fine though. After trying some diffrent settings and also making a RAID 0,1,5 and basic RAID setup the speed still seemed to stay really poor,.. I blamed the network settings at first but noticed my raid5 3 HDD setup manages to keep a steady 500-600MB/s (Bytes not Bits) while transfering from my pc to the XPEnology. Copying a large file from one SSD to another gave me the same poor performance. At the Benchmark in the storage manager the SSD read speed caps out at about 550MB/s but the Write caps out at about 30MB/s. I've tried a different ssd, port, cable and controller so far but nothing seems to help. Booting up Windows and benchmarking the SSD with Crystal Disk Mark gave me about 550/500 Read/Write on both SSDs. I'm using DSM6.1.4-5 on 1.02b with the extra.lmza v4.3 driver package on a SuperMicro a2sdi-h-tf motherboard. I have come across a couple of seemingly similar cases but these were unsolved or different causes (like SMB and networksettings). Does anyone have a tip for me to try out or could give me some advice? Kind regards, Mike
