Hi, I got a leftover OWC 480 GB Aura SSDs from an old 2014 Macbook Air. Is it possible to reuse it in a 2017 27” iMac on the logic board?
Attached is a picture of the drive and also a link to the data sheet from OWC.

Thanks for any advise

Hello,
I installed eventually a Crucial MX500 Sata SSD drive and my old OWC Aura PCI blade from a 2014 Macbook Air. Both work nicely together and the performance is a big step up compared to the Fusion set up. Total space is now 1TB which is enough for me.
Benchmarks below. Although the Aura performance appear a bit odd. Fast enough in real-life for me nevertheless.

Lets use this as a reference: The Ultimate Guide to Apple’s Proprietary SSDs.
So referencing it we can see the MacBook Air SSD is only offers a PCIe 2.0 x2 interface using AHCI Vs PCIe 3.0 x4 using NVMe. So while the connector interface will likely support it. It won’t offer the best performance the interface could offer. Basically is no faster than a SATA III (6.0 Gb/s) drive.
I’m not sure if the older OWC Aura SSD offers NVMe services, in any case it will only be using two lanes Vs four lanes.

Appreciate your time Dan, thanks!
The OWC Aura drive offers around 700MB/s for read and around 400MB/s for write (from the specs sheet). Considering that this is the real-use average I could get, how does that compare to the 1TB Fusion drive I have currently installed.
I could not find any benchmark for the 1TB fusion drive anywhere. Any link to a benchmark report is appreciated.
Thanks
Stefan
I don't do Fusion Drives! I find them very lacking in performance.
I do strongly recommend straight dual drive configs! That is at least a 512 GB blade SSD (PCIe/NVMe) as the boot drive with just the applications and nothing else! Then using a SATA III (3.0 Gb/s) HDD or better yet a SSHD for the data drive. If you are into video or large image processing then you'll want an external TB3 SSD or RAID'd HDD or SSD for your work drive.
Your OWC blade SSD is just hampered by its age. Its better than a HDD for sure as unlike a HDD which over time gets fragmented so over time it gets slower, SSD's don't encounter that. It's just iffy if it will work in the newer system.
