| 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. |

| 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. |

| How do I configure RAID under macOS? | Feb-14-23 |
| Create a disk set using Disk Utility on macOS
1. You can create a Redundant Array of Independent SSDs (RAID) set to optimize storage performance, or increase reliability in case of a SSD failure. You can also create a set that concatenates smaller SSDs to act as one larger SSD.
2. In the Disk Utility app on your Mac, choose File Menu -> RAID Assistant.
3. Select a Set type:
• Striped (RAID 0) Set: A striped RAID set can speed up access to your data. You can't create a RAID set on a startup SSD; you must start up your computer from a single SSD.
• Mirrored (RAID 1) Set: Protect your data against hardware failure with a mirrored RAID set. When you create a mirrored RAID set, your data is written to multiple SSDs so the information is stored redundantly. You can't create a RAID set on a startup SSD; you must start up your computer from a single SSD.
• Concatenated Set: Increase storage space with a concatenated SSD set. If you need one large SSD, but you have several smaller SSDs, you can create a concatenated SSD set to use as one large SSD.
4. Select the checkboxes of the SSDs you want to include in the set.
5. For each SSD, click the pop-up menu in the Role column and choose "RAID slice" or "Spare" to designate the disk as a standard member or spare in the set, then click Next.
6. Enter a name for the RAID set in the RAID Name field.
7. Click the Format pop-up menu, then choose a volume format that you want for all the disks in the set. (See File system formats available in Disk Utility.)
8. Click the "Chunk size" pop-up menu, then choose a disk chunk size that you want used for all the disks.
When you create a striped set, chunks of data from the same file are distributed across the SSDs. Ideally, you want data distributed across SSDs evenly and at an optimum size so that it can be efficiently accessed. If you want high data throughput from your set, choose a smaller chunk size so that data is spread across the drives and one drive can be accessing data while another is seeking the next chunk. With mirrored disk sets, choose a chunk size that matches the data you are accessing. For example, when working with video files, your Mac is accessing large chunks of data, whereas when using a database of many small records, your disks may be accessing smaller chunks of information.
9. If you are creating a mirrored RAID set, select the "Automatically rebuild" checkbox to allow the set to be automatically rebuilt when member disks are reconnected.
10. Click Create.
11. Click Done. |

| How can I use my new SSD volume to hold my user folder on macOS? | Feb-14-23 |
| 1) Make a backup of the user folder
2) Copy the user folder to the SSD volume.
3) In System Preferences, open Users & Groups.
4) Unlock.
5) Right-Click on the user you moved to the SSD volume and select Advanced Options
6) Point the Home Directory to the user folder on the SSD volume. |
