Notes

Hosts with Thunderbolt 3 ports will experience performance up to USB 10Gb/s.
NVMe SSDs with heat sinks will not fit and are not supported.
OWC storage solutions that are experiencing slow read/write speeds should consider checking and changing the Windows disk removal policy. Changing from ‘Quick removal’ to ‘Better performance’ can increase disk performance. OWC offers the application OWC Disk Performance to help change the Disk Removal Policy. Changing from Quick removal to Better performance can also be changed manually. Please review the support article Storage Solutions: OWC Disk Performance for more detail.

Fast SSD's on my Apple Mac at last.

I had been thinking for some time about buying two USB/Thunderbolt enclosures to get more speed from my two Samsung 980 PRO PCIe 4.0 NVMe M2 SSD’s with 2TB capacity each and finally made the jump.

I had been using for the past 18 months another brand 10GBPS enclosure with USB-C 3.2 specifications and getting on average 965 write and 960 read speeds tested using the Blackmagic app. on my iMac Pro 2017 and of late on a 2024 Apple Studio M4 MAX and both machines were at the same figures, seemed that was the limit on the USB-C 3.2 enclosure.

I had found information on the OWC Express 1M2 USB4 (40GB/s) Bus-Powered Portable External Storage Enclosure and it sounded excellent but expensive as my price was doubled needing two units. I jumped in at last and Macfixit had them in stock and just hours after my order was in they were in the mailing system I paid the small premium for Aust.Post EXPRESS well worth it down to Tasmania.

Both SSD’s fitted, dead easy install and using the supplied USB-C 4 cables plugged into my Apple Studio M4 MAX and doing the same tests as above opened my eyes when I had write speeds around 3500 and read speeds around 3270 amazing to see the indicator needle just fly right up to those speeds, breathe easy, money very well spent. Buying un seen un-tested just relying on reviews and other persons comments can be a risk as we know we should not believe all we hear and read online, however this buy was a total win for me.

WARNING, anyone still using older systems like my iMac Pro 2017 (I absolutely love this unit) however the OWC Express 1 M2 will not improve your speeds when used on ageing devices it is the USB speeds that hold it back. I suggest you do your own homework, I haven’t stop smiling when using my M4 Studio MAX since adding the OWC Express 1M2.
