Hi y'all,

I just upgraded my 2015 15" Macbook Pro with an Adata XPG SX8200 Pro (1TB) and used an adapter similar to the oft recommended Sintech Adapter (the one I bought was cheaper).

All fits and all works, but I am only getting speeds of 1600 write and 1450 read (as with the original Apple drive), shouldn't this SSD be twice as fast in a 2015 Macbook Pro? Will the adapter influence the speed?

If anybody has had similar experiences with this SSD and/or any solutions, would love to hear them!

Many thanks

Have you update your bootrom version to the latest?

Hi, and thank you for your answer!

I have a Macbook Pro 11,5, I am running Catalina 10.15.7. and my bootrom is 199.0.0.0.0. Should be current.
Is there an update available that I am unaware of?

Thx!

Hi Vince,

Thanks for that, yes, my Macbook has those specifications, PCIe 3.0.

I did a bit of research on this, it seems that Adata quietly changed their controller from Samsung SM2262EN to the (slower, I read) SM2262G.

The drive I bought was indeed a revised version, so I returned it. Not sure if the controller was the culprit, but since my proprietary Apple drive has the same exact speed specs, I thought I'd save the money. :)

Thanks again for the input, appreciate it.
