    Hi,
    After upgrading ram and cpu i want to upgrade my HDs (i use my mac for music recording)
    In this moment i have a ssd owc on slot 1 for booting and apps. If i understood well i will not have any benefit if i move it on a pcie card. The overall performance will remain quite the same...no benefit for the value/price. For this reason maybe i can use a ssd pci for storage libreries that need fast read/write performances (ssd or m.2?)
    Moreover, i'd like to add a 6TB HD (wd black series) for storage other libreries. Is it better to use internal sata bay or a usb 3.1 pcie or esata pci?
    Thanks

    For HDD, in general, using internal port is better for stability issue. e.g. external HDD may experience ejection during sleep / wake cycle. And there is no performance advantage to go external, but only increase cost, complexity, cables.... in order words, more failure points for no advantage.

    The only scenario that I know go external may be better is some of the large capacity HDD (mainly design for NAS use) may not able to mount properly after warm restart (cold boot is fine). In that case, go external usually can fix this issue.

    For very large apps library, yes, PCIe SSD is a good storage option.

    Also yes, there is no noticible performance benefit to boot from PCIe SSD (vs SATA SSD).

    I use relatively small Samsung SM951 ACHI on Angelbird PX1 PCI-E for system, and larger SSD in HDD bay + experimenting with Seagate Firecuda.
