This is really disappointing. I also ordered from AliExpress because Polysoft didn’t deliver my original order, and still I haven’t received any proper tracking information from Polysoft. This situation is causing a lot of stress for customers. At least if they communicated clearly, we would feel safe. But right now it feels like they are holding customers’ money and breaking trust. Buyers should be very careful.Suddenly got a UPS message, 'polysoft delivery due tomorrow', no email, tracking number or anything from polysoft. I requested to cancel and be refunded on 21st Nov, heard nothing, started charge back with bank, and did the French consumer right thing, so my order says SEPSA dispute. Meanwhile I have ordered from Ali. What to do?
Unfortunately no. It was explained that modules 0 and 1 are NOT the same: They only work as a pair, each in the right slot. So you cannot collect two "0" modules and use these for 4 TB total.Anyone know if I could use 2 x 2TB modules, one in each slot, to give me 4TB upgrade?
By any chance did you bench the memory with black magic speed test ?View attachment 2585052

It's here! (Polysoft order from March 2025)

If the SSD nand chips are virgin (on the 2 modules), you could try to put 2*2Tb on your Mac Studio and it'll work.Thanks, I had a feeling that was the case, I assume re programming one of them is not something I can do myself 😔
On the contrary, that part is working exactly or better than what apple designed it for.This specific plastic part is simply not well thought out on Apple's part
For those who were asking, I also got the M4 8TB drive from Fangyuan on AliExpress.
Funnily enough, it seems to be higher priced at first if you're within the EU, however once you go to the payment steps it reduces the amount quite significantly.
Delivery took a little bit but at least they shipped almost immediately and the little cards are safely packaged.
Installing them was a breeze where I just followed the iFixit guide for replacing the cards, once you get the bottom screws loosened you're basically golden. That's the only part where I wasted some time until I got pliers to gain leverage.
Putting the machine in DFU was straightforward, same with restoring. Only downside is that it's now running Tahoe and it's an ugly piece of garbage system.
Anyways, I'm VERY happy I went away from PolySoft and just ordered from AliExpress, considering that I even paid almost 150 EUR less than before.
Here's a reminder that YOU MUST HAVE A SECOND MAC FOR RESTORING. The entire hardware swap might work, but you can't restore the machine if you don't have a second Mac. Just in case you weren't aware.
I used the included instruction manual.Did you take the 2023 MAC M3 studio as template for ifixit ?

How to Remove the SSD Modules in Your Mac Studio (2023)
Before starting this repair, note that Apple doesn’t support SSD swaps or upgrades at this time. This guide shows how to remove one or both SSD...fr.ifixit.com
In the process of getting refunded for that
I want refund. I have purchased the disk from from aliexpress due to the delay. Please do the refund soon.Hello everyone,
First of all, I would like to once again offer my deepest apologies for the enormous delays.
My primary motivation for undertaking this project was to serve the community (as I have always done here on MacRumors, in other threads), and I apologize for causing concern and inconvenience with my delivery and response delays.
With a lot of effort to automate testing, we are currently delivering between 10 and 20 kits per day. We will not have made up for the backlog before early January.
It is important to note that we test each kit individually for several hours on a corresponding Mac Studio (we have several Mac Studio testing devices : M1, M2, M3, and M4).
We use new NANDs and perform a full write pass on each kit, with no compromise.
I have hired an employee to handle administrative tasks.
This is not an excuse, but to explain why we have had delays: my partner had serious health issues and has been absent for several months, and I have myself not been very available due to serious personal and family issues.
Once the delivery delay has been cleared,, I will be happy to take the time to answer questions here. I apologize for not being able to do so at the moment.
It should also be noted that no one has been or will be disadvantaged: more than 70 customers have asked me for refunds and have been duly reimbursed. I would like to warmly thank the others for their patience.
It should also be noted that I am trying to develop a device to reprogram the chips “in situ,” without desoldering them, which would make it possible to easily upgrade from 2TB to 4TB, but this is not a project that will likely be completed before next spring.
I will publish the files and gerbers here.
We will also try to keep prices as low as possible. I believe we are not among the most expensive.
In recent months, NANDs have increased significantly (and contracts we had signed and paid for were not honored... we remain “small players”).
@gilles_polysoft, thanks for your update! I just wanted to mention that my order EIJFPZUJX from October 2025 seems to have been forgotten. According to your website, it was 'in stock', but I have received nothing. I already requested a refund in November, still without any confirmation.Hello everyone,
