Rockpro64 has more powerful CPU and GPU. However, for media player and NAS area, just stay with ROCK64.
Hi TL, I'm very happy about my Rock64 NAS setup equipped with a 2-bay USB 3.0 dock and 2 HDDs sitting on it. However, the bandwidth is bottleneck by single USB 3.0 which the speed will split in half when 2 HDDs using at the same time.
Q is, will Pine H64 equipped with mini PCIe to 2 sata card performs better for a 2 bay nas use, like supporting 2 native sata and their speed under Openmediavault? Is it worthy to update H64 from Rock 64? Will either RockPro64 or H64 support one or two SATA or USB expansion cards in long run?
Much appreciated for your read and answer.
Cheers,
David
Its 4 lanes so that is 4x500MB/s raw transfer which bottleneck 4x fast SSD but would be fine with x2.
I have forgot what the encoding overhead for Sata and PCI-e lane is but some mirky mem says 20% so buy 400MB/s SSDs and your on a 4 way winner with a 4 lane x4 pci-e sata card I guess.
Thats unusual it is 20% http://www.tested.com/tech/457440-theore...underbolt/
