| I'm using OWC Mercury Extreme Pro 6G SSDs with a Tempo SSD or Tempo SSD Pro adapter in a Thunderbolt Expansion Chassis and the system hangs after waking from sleep. | Oct-01-16 |
| You need to upgrade to OWC 6G firmware version 5.0.2 (released March 13, 2012) or greater. |

| How fast will an SSD be in an Echo Express Thunderbolt chassis using the Tempo SSD, SSD Pro or SSD Pro Plus? | Dec-30-17 |
| We have performance comparison information on our web site. Check the performance tab on Tempo SSD or Tempo SSD Pro product page. This will give you a pretty good idea.
These numbers can be generalized. For one SSD you can infer from the table.
Read speed over Thunderbolt = 90% of rated read speed in a Mac Pro
Write speed over Thunderbolt = 80% of rated write speed in a Mac Pro.
Go to the manufacturer's SSD product page, check the speed rating and multiply by 90% and 80% for read and write, respectively, for performance over Thunderbolt.
For two SSDs in a RAID 0 in the Tempo SSD Pro using the original Thunderbolt 1 bandwidth limit, the speeds get capped at about 700MB/sec read and 560MB/sec write. There is no bandwidth limit for a two-SSD RAID 0 under Thunderbolt 2 or Thunderbolt 3. |

| 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 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. |
