What is the recommended operating temperature for my RAID enclosure?
This depends on the specific model. Please check the product web page. The "SPECS" section near the bottom of the page will provide the recommended operating temperatures and non-operating (storage) temperatures for your specific product. You will also find other useful information in this section, including but not limited to things like boot support for your OS and compatible PCI cards.

Can I daisy-chain my RAID enclosure?
If your enclosure has two Firewire 800 or two Thunderbolt ports, yes you can chain other drives to your RAID enclosure using the spare connector. However each drive that is added to the chain must have its own power supply. Your RAID enclosure is not able to power additional devices that are attached to it.
Can I connect my RAID enclosure to more than one computer at the same time?
No. All of our enclosures are designed to be connected to only one computer at a time. Connecting an enclosure to more than one computer may damage the data on the drive, the enclosure, or both.
How much space will I have available to use for data with a RAID 5?
RAID 5 volumes will hold one drive aside for parity data (note: RAID 5 requires at least 3 drives be used). Therefore if you have a total of four identical drives in your RAID 5 volume, the total available capacity will be equal to the combined total of three of those drives. If you have a total of three identical drives in your RAID 5 volume, the combined capacity of two of those drives will be available for use.
How many drives in my RAID volume can fail before I lose my data?
This depends upon the RAID mode. For SPAN and RAID 0, just one drive failure will likely result in all data being lost. For RAID 1, RAID 5, and RAID 10, one drive can be lost without losing your data. However if more than one drive fails in a RAID 1, 5, or 10, all of the data will likely be lost.
Is there a battery backup built into the RAID enclosure?
No. None of OWC's RAID enclosures have built-in battery backup capabilities. If you want your enclosure to benefit from a battery back-up in the event of a power outage, you may want to research the different external battery backup options that exist for your computer and general setup.
Can I set up my RAID 1 or RAID 5 drive with multiple partitions?
Yes. Once the array has been created by the hardware or software, you can set up 1 or more partitions the same as if it were a single disk.
