| How do I configure RAID under Windows 10? | Feb-14-23 |
| 1. In the Windows search box, type "Storage Spaces".
2. Select Create a new pool and storage space. Windows will check all eligible volumes and list them in the next window.
3. Select the SSDs you want to include in the RAID and click Create Pool.
Warning: All data on the drives you select will be erased, so back up any important data before continuing!
4. After creating a pool, you'll be prompted to configure your new storage space. Type a name for the storage space and select a drive letter. The storage space will appear with this name and drive letter in Windows. You can select either the standard Windows NTFS file system or ReFS, the new resilient file system. If you'll be using mirroring or parity to protect against data loss, we recommend choosing ReFS for its file integrity protection features.
5. Choose a resiliency type. Select Simple (no resiliency) for a large RAID 0 pool of storage that combines the speed of the included SSDs, but offers no protection from a single SSD failure. Select Two-way mirror (RAID 1) to store two copies of your data across two SSDs, or select Three-way mirror (RAID 1) to store three copies of your data across three SSDs. Select Parity (RAID 5) to be protected from a single SSD failure across 4 SSDs. Parity will offer protection with increased size (3/4 of the combined SSD size), but a parity space is noticeably slower than the other options.
6. Choose the size of your storage space. The default will be the maximum available amount of storage you have, which will vary depending on the type of space you create. SImple maximum should be a sum of the sizes of the included SSDs. Mirror should should show the size of a single SSD. Parity should show the combined size of three (of four) SSDs.
7. Select Create storage space when you are done configuring your storage space.
8. The storage space you created will appear as a standard drive under This PC, with the name and drive letter you configured. It appears no different from a normal, physical drive to Windows and the desktop programs you use. |

| Programming SSDs to 4k Block Size for Compatibility With macOS 10.13.6 | Feb-08-23 |
| macOS 10.14.6 supports both 512 and 4k block size SSDs, but macOS 10.13.6 supports only 4k block size SSDs. Today, most SSDs are shipped from the factory programmed with a 4k block size. If your SSDs are programmed with 512 block size, however, and you need to be compatible with macOS 10.13.6, you must reprogram your SSDs to a 4k block size. Sonnet has written a script to do this, but it needs to be run on a Linux computer. You can download the instructions here. For a copy of the script, contact support@sonnettech.com. |

| 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. |
