on my new N54L (with patched BIOS/Settings, including e.g. SATA: up to 3GB, AHCI,...) with 4 SATA HDDs i installed DSM 4.2 initially and had Transfer rates at 80-100 MB/sec (over several 100 GB!)
Thereafter I upgraded to DSM 4.3 and now my Transfer rate is down to 40-50GB/sec (I didn´t Change nothing in the BIOS!)
Even after a complete reset/new Installation of DSM 4.2, the Transfer rate is still "only" 40-50GB/sec.....during boot process I now spotted the following messages for all SATA Ports: "SATA max UDMA/133" respectively "configured for UDMA/133"
Could anyone please support how to arrive back at the earlier Transfer rates?
Thanks in advance
