| The Write performance of my SSD is very slow under Windows. | Feb-14-23 |
| The Windows default for any external storage media is for Write Caching policies to be disabled. If you have enabled it, then the write performance to an SSD will be very slow. To get significantly increase write performance, disable Write Caching. For instructions, see this Microsoft Document. |

| 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. |
