| In a Mac Pro, the SSDs are seen as external drives, how do I prevent accidental ejects? | Feb-14-23 |
| There is no provision in macOS to make SSDs on a PCIe card to appear as internal and non-ejectable. If you want to prevent accidental ejection, open a file on the volume with Text Edit, which will prevent macOS from ejecting the volume, because a file will be in use by Text Edit. |

| The x8 PCIe lanes can deliver up to 7.8 GB/s. How do you fit the RAID, the 10gig lan and the 2x USB 3.2 in this bandwidth? | Jun-08-22 |
| The most important design feature is that every device is connected at its maximum PCIe 3.0 lanes: each SSD@x4; USB 3.2@x2; and 10GbE@x2, which gives each device its maximum usable bandwidth: SSD@3.5 GB/s x2; USB 3.2@1.0 GB/s x2; and 10GbE@1.0GB/s. Adding up the total bandwidth is indeed greater than 7.8GB/s, but considering that PCIe input and output bandwidth are independent, one can achieve the full 11MB/s bandwidth of simultaneous use of the devices as long as there is a mix of reading and writing. It is extremely unlikely that one would need to use all the ports simultaneously, at full bandwidth, and all writing-or all reading. The alternative of a larger PCIe bridge chip to connect to the computer at x16 would have increased the cost of the McFiver, without any performance gain in virtually any practical use scenario. |
