In parallel with my projects with NAC-HD1E GIGAJUKE I get faulty NAS-S500HDE from eBAY as the main component of NAS-SC500PK system.
I was surprised that this unit is about 3 times slower than NAC-HD1 GIGAJUKE. The main problem that causes freeze also from my previous posts considering insufficient amount of RAM, but this device has some problems with P-ATA to S-ATA bridge. I connected SSD disk to check performance, there was no performance gain.
