Faster is nicer, but cost is a > constraining factor. Aside from these Marvell's I don't know any other AHCI HBA with FBS support. And HBAs without FBS are by definition are not suitable for simultaneous access to devices on PMP. Aside from AHCI, older Marvell's supported by mvs(4) like 88SX7042 can do FBS, but IIRC they are also not very fast and I don't trues them much either. -- Alexander Motin
