So I want to upgrade my 2019 Mac Pro to 8TB of SSD storage, thus replacing the 2x2TB Apple modules I currently have installed. However, it doesn't matter where I look, I cannot find a single kit out there. The only thing I could find was the SSD kit for the 2023 Mac Pro.

I contacted a friend of mine who is an Apple ASP, and it would cost him nearly 3200$ to get one directly from Apple.

Is there really no other way to get this upgrade without breaking the bank? I know, I can just use PCIe SSDs, but I would rather upgrade the internal SSD since all my PCIe slots are populated.

I would not recommend purchasing a used Mac Pro from the US. ebay charges the VAT, but fail to register the payment correctly. So we end up having to pay the VAT again, when it arrives at the national customs.

EU made changes to the iOSS digital system, when Trump launched the tariffs last year. So it has been a complete mess, ever since. 🙁

This is an issue that even cause problems in Norway, and it was reported on a news site.

So they still have them, interesting.

I do recommend to get PCI-E card and NVME storage.
Maybe NAND exchange is an option for you: https://forums.macrumors.com/threads/apple-silicon-soldered-ssd-upgrade-thread.2417822/
The process is very similar to Intel-based Macs with onboard SSD.
I don't know if fitting NANDs are still available, perhaps @dosdude1 can give reliable answers.
This would be interesting if it were possible to do, but as with most things, Apple made the simplest things frustratingly difficult and silly. It's like they thought back in the old days, let's make sure we design the machine with the ultimate potential to upgrade be almost useless (no GPUs newer than ancient 6800/6900 series and hard to find bespoke storage).
 
Because of that, i don't buy any Apple products. Really frustrating to see the totally closed devices with no changeable parts. I mean: easy change for the end-user.

SSDs are changeable on Mac Studio, Mac Mini, actually not too difficult to do.

There are after market solutions for Mac Mini and Mac Studio which are cheaper but not Mac Pro 2019+
 
You probably better off buying another 2019 Mac Pro w/ 8TB SSD and selling your current one to offset, or some variation of swapping components. There's one avail for $3500 or BO.
Generally not a bad idea, although 6500$ is still a lot of money..

Sounds interesting, not that experienced with soldering though

Waste of money. Just get a PCIe card and add any NVME you want to it as a second drive. How are you filling all your PCIe slots?
Currently I have a Vega II and the Pegasus R4i, as well as a 4-port Sonnet USB 3.1 card. Oh and also a Radeon RX 6900 XT at the moment, so I currently have no space whatsoever to install PCIe SSDs.

Not to get too political, but ever since the Trump administration has been in charge, international shipping / buying from and to the US has been an absolute nightmare. Really annoying and also pointless to be honest, a lot of sellers on eBay don't even ship outside the US anymore for these reasons.

So they still have them, interesting.

Yes, I had a chat with him and it is quite interesting, you can buy any parts for the 2019 Mac Pro you could possibly want through service. They can get you any GPUs, RAM, SSDs, housing and what not. Apparently he also told me that Apple will still continue to supply and produce parts until at least 2030, so exactly 7 years after the device has been last sold.
The prices are very hefty though, two W6800X Duo modules still cost around 4k$.

Well it did make sense as to why Apple did not provide support for the 7XXX/8XXX/9XXX Radeon series, look at the Metal benchmarks. The 6950XT STILL dominates the benchmarks 5+ years after release, so if they kept supporting even newer AMD GPUs it would take ages for Apple silicon to catch up 😅

Because of that, i don't buy any Apple products. Really frustrating to see the totally closed devices with no changeable parts. I mean: easy change for the end-user.
Sooo you don't buy Apple products but you are on a forum dedicated to Apple tech? How does that work? Besides, the parts ARE replaceable, it is just a matter of money.

How do you not have 1 PCIe slot left?

I have the 6900xt on Slot 3
I can install it on Slot 1 since its a double slot card and still use Slot 3 for a smaller card (although it will block one and half of the fans on the 6900XT)

Then I have a NVME PCIe card and also Pegasus for SATA drives (which doesn't take up PCIe slots).

That means I have 2-3 slots left.

You should have 1-2 usable slots left for a smaller card. If I were you I would get rid of the PCIe Sonnet card if you truly don't have a slot and use a Thunderbolt > USBC hub. There's plenty and put in an NVME card.

There are also USBC + NVME PCIe combo cards out there worth trying.

Would like to know more about that in case I need to upgrade my W6800 machine to W6900.

Generally it’s not possible to get anything in Australia. Soon as you mention that country name everyone runs and hides.

No worries! I'm from Germany, so he's also from Germany. Although I also asked in a German official Apple Store once for a new power cable for the 2019 Mac Pro and while the Apple Store employee was on his iPad to look for the part, I could get a glimpse of the app they use internally to get parts.
And I can confirm since I asked him as well, even the official Apple Store can get still order parts for the forseeable future for the 2019 Mac Pro, albeit a bit pricey. The cheese-grater housing will cost you 1.501,29€. So maybe not the cheapest option, but hey if you do need parts which are really hard to find that is still somewhat of an option!

I could be able to get one slot free by getting rid of the Sonnet card. Are there any restrictions by using a PCIe SSD as boot drive compared to the proprietary SSDs?

You should be able to boot from the NVME if that's what you want. I would advise against it though, just use the NVME as a secondary device.

If you decide to boot from the NVME, then you have to allow booting from external devices in the Security Settings in the Recovery mode.

But to me that is my main issue, I want all my main data to be stored directly on the boot drive. Having an external PCIe card is gonna come with its fair share of issues down the road in quite a lot of areas. It's really stupid that these are proprietary..

Then get an NVME and boot off that. I did a quick search and it seems that it's possible. AFAIK you have to leave the default SSD in there but you can leave it blank/use it for other things without issues.

They are propietary because there is no SSD controller on it, the controller is on the T2 chip. On M class macs, the controller is on the SoC.

The Mac Pro was/is a low-run manufactured Mac so there's no 3rd party replacements afaik. Like said earlier, the Mac Studio and Mac Mini has 3rd party alternatives.
 
Well secure boot is not an issue to me either way, since I have booting from external devices turned on and Boot Security turned off anyways.

I know why they are proprietary, I would have just preferred Apple to use standard NVME drives instead, that would make things much easier.

Honestly why are you wasting any money on the 7,1? It's a dead end product.

Just stick with what you have and if you need extra storage just pop in a SATA SSD or a spinner internally, not even an NVME which are expensive right now.
 
Maybe I'm old school, but I have always practiced only using my primary boot drive for OS and app installs, plus the day to day user files ie Desktop, Downloads. Everything else, application scratch, working files, assets, media all go on different drives. I don't think I've ever had a boot drive over 1TB yet.

Agreed with this. I have a 4TB OS drive and definitely use it for cache files, apps, and random stuff that is backed up by a 8TB Time Machine. Generally work off of a NAS via 10GbE for projects.

You guys now got me thinking of switching to a NAS as well and only keeping local backups of some stuff on the Mac Pro.

Been looking into Ugreen's offerings now, but I am not 100% sure if I should trust a Chinese company with my data. Would probably have to run TrueNAS on it.

So long as your data structures aren't things that need to be on the boot drive, or on APFS, a NS is probably a good idea, especially as more and more useful software disappears as Mac-specific versions and requires docker etc, a lot of that stuff you may as well run on a NAS.

UGreen is a good brand, but never tried their NAS. I stick with known brands like Synology and run RAID 5 or RAID 6. It's been running for years 24/7 with no issues. 96TB of space. I generally offload/archive old files from it to external drives (usually to 2 of them for dual backups).

Currently have a 6 bay Synology running raid 5 with a 10GbE card inside directly connected to my Mac Pro and I get around 700MB/sec which is perfectly fine for what I'm doing. I can add an NVME to the PCIe card as a cache drive and probably get 1GB/sec+ but don't want to spend anything with current NVME prices.

What's nice about NAS is that it also runs on my local network via the built in 1GbE and I can use it on other computers in the household for other stuff like Plex server etc. and on my Apple TV (I use Infuse for highest quality streaming) on my projector or work off WiFi with my laptops. Also what's nice is that computers can change and I will still have my drive space always available so I am not tied to internal storage for work (even though I do use internal storage for work sometimes for smaller projects). I just got a WiFi 7 wireless router (used to be WiFi 6) and pings and downloads are pretty dang fast, above 1GbE.

If you do want to get custom you can get a cheap Mac Mini and run a server off that, but what I like about NAS is that it's its own thing and has its own OS and a bunch of features and easy to use. Initial cost is a little higher (I paid around $499 for the empty NAS + whatever the drives cost). Totally worth it long term. It has paid for itself a long time ago.

The Power Mac and OG Mac Pro enclosures were also expensive. Occasionally all troubleshooting would fail and Apple's recommendation was 'replace enclosure' for repair. Sold a couple of empty cases to modders for a bit of change. 🤣

Got a handful of small businesses running on these. Super easy setup, rock solid so far, performant. They're all 6 bay spinners, dual NVME cache drives, 32GB RAM, 10Gb ethernet. File sharing, multiple 4k movie streams, everything is snappy.

[edit] Also, a Mac mini with TB2 storage and TrueNAS makes for a snappy little server on a budget.

Alright Dave (I'm assuming), you convinced me! It does not make sense to upgrade to 8TB. For the cost of that SSD, I could get two Samsung 9100 Pro 8TB and the Sonnet M2 4x4 Adapter, and still have some money left over. So instead of basically 4TB more, I can easily get 16TB for the same cost.

With the added benefit of being able to just take the card and put it in my M2 Ultra Mac Pro once I bought one.

I saw a pretty good offer, an M2 Ultra Mac Pro with 192GB, 76-Core GPU and a 1TB SSD for just under 6500 Euros. I'm really considering that right now. Comes with new Magic Keyboard, Magic Mouse and Magic Trackpad, all USB-C, which right now would cost 400 Euros alone.

What do you think?

Also, I am also planning to build a NAS now, although I still have to find affordable HDDs because I am not paying the inflated AI prices. Looking at probably 12TB+ per drive, with a 4-drive NAS. Either Ugreen or Synology, still comparing the two! Which model do you have?

A Mac mini is probably not the best option. They are most likely gonna be slower and I cannot manage them as easy as a dedicated NAS. Plus, I don't fully trust old hardware running 24/7 with my precious data haha
