I'm looking for 16+ ports sata 3.0 controller for disks already initialized from Windows 10 (with GPT and NTFS volume) for pcie 3.0 motherboard, and I want to access to the data without any change (no other initialization for formatting).

I found sata controllers dedicated to chia farming, can they be used for JBOD also ? Which one do you recommend ?

Will their reliability be significantly different from a Broadcom controller ? Also there are no certification or norm: is it critical ? No MTBF: what should I expect ? The Broadcom 1500-16i for instance has 5 Mhours MTBF !

I think Chia farming is JBOD, but the speed of that controller is really low, since it only uses one lane. My reccommendation is to look for a controller with about 1 lane for 4 SATA ports for maximum performance. I don't know if those exsist, but now you know what to search for.

  • Instead of "speed is really low" can you provide a value ? There is also 12 ports pcie 4x !

  • 12 ports 4 lanes should be good

  • OK. You want to update you answer with new details. Not a word about reliability and norms ?

  • SATA is SATA, PCIe is PCIe, and I don't know if there is much more
