Hi! I found cheap PCI-e SSDs on eBay (eBay Link). The reading and writing performance look good for that price. But there is no information about its compatibility to Mac. Does anyone have any experience using enterprise PCI-e SSD on Mac, such as Mac Pro 2012 or 2019? Thanks!

I find it odd that the pict of the SSD is the same pict as listed on Amazon.


Spec Sheet is here:

Yeah, there are other options on eBay. Maybe I could order one from Amazon to give a try.

Note that these are standard PCIe card form factor.

Most of the "PCIe SSD" threads here are discussing the much smaller "M.2 PCIe" cards.

Thats a lot of money and a huge gamble that the MP would be able to use it for much more than *possibly* some form of storage / scratch disk, I'd sink that money in a 4x m.2 carrier card and 4x NVME SSDs and likely have a better solution in the end.

Unless you are feeling very brave I would not risk it. I was tempted and did some digging. On another thread it is stated that Apple use NVMe protocol v.1.3 in all their SSDs. If you look at the spec sheet for the Samsung drive it runs on NVMe v.1.2. Without trying it who knows, but the omens do not look good!

Asus HYPER M.2 X4 MINI CARD, the one blade version, works fine.

ASUS HYPER M.2 X16 CARD is a 4-blade adapter that requires bifurcation, or more correctly Intel PCI Express Lane Partitioning support, that no Mac supports it.

For people that will read this in the future searching about this 4-blade adapter, don't buy this card since only one blade of the four that the card supports will work when installed in a Mac. Read more on the first post of the thread PCIe SSDs - NVMe & AHCI.

AFAIK, no one tested this HHHL NVMe device yet.

Apple have a god tracking of supporting NVMe M.2 devices, just some oddballs are incompatible, but the support for U.2 and HHHL devices is less than stellar. Several Intel and Huawei HHHL/U.2 devices were tested and found not compatible with Mac Pros.

For big capacities NVMe devices, look at Micron 90xx/91xx/92xx drives, all tested up to now worked fine.

Im using the Asus Hyper M.2 x 4 minicard ( single nvme blade). Sorry I forgot to mention on my previous post... tsialex is right , the Asus 4 blade adapter is not fully compatible ....

Question - would the new M.2 interface SSD drives fit in a late 2012 mini bay?
