1069 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.

1077 Programming SSDs to 4k Block Size for Compatibility With macOS 10.13.6Feb-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.

1183 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.
