Innergize Your Workflow with Highest Performance and Reliability
- Health: Over time and use cycles, flash memory does wear out. Innergize verifies and reports the percentage of use life remaining. Now you can work with full confidence your OWC Atlas memory card will deliver the reliability you can trust.
- Sanitize: Writes, deletes, and formatting all take their toll on memory cards. Innergize cleans and restores the flash memory performance of your OWC Atlas memory card so you can get the best results on every use.
- Field Upgrade: When new cameras or firmware updates to existing cameras are introduced, they may not work properly with flash memory cards. Innergize gives OWC Atlas memory card users the ability to quickly upgrade their firmware in the field for full compatibility, additional performance enhancements, and bug fixes for optimal reliability.
- SAS drives are supported with SAS drive controller card (available separately).
- Up to four U.2 drives are supported. M.2 drives are also supported with M.2 to U.2 adapter (available separately).

Customer Reviews
The enclosure went together well and is working with 5x 12Gbps SAS and 2x 4TB NVMe. So far so good. Biggest issue was finding a SAS solution for my M1 Mac. Ended up with a HighPoint R710L which is working well. I also tried a few other including ATTO however every time I tried doing a Black Magic speed test with the ATTO the system would hang and reboot. The HighPoint was less expensive.
I would recommend this product to a friend!

Thank you for the amazing feedback! We're thrilled to hear that the enclosure is working well for you, especially with your M1 Mac setup. We appreciate your support and are always here to help with any future tech needs. Enjoy your high-speed storage solution!
It’s great to have such mega storage, but every time it goes to sleep, or when I first plug it in, it takes way to long to boot up and be recognized by my max.
I would recommend this product to a friend!
