I'm with #6 and I very happily own an M1 Studio. We all know that Apple will obsolete the M1s before the M2s... even if they are still quite capable of carrying on into about 2028 and beyond. With some OP indifference about which to buy such that he's asking strangers, M2 is likely buying 1-2 more years of use beyond when Apple decides to vintage M1s.
With Silicon Macs, this is not about how well either works right now. Both generations roar right now. It's about how well each will work in the future. Likely no later than about 2028, M1s will be vintaged... and I will not be the least bit surprised if modern Apple won't offer some strong reasons to "upgrade" sooner than that (including key features in macOS not "being compatible" with "old" M1s (even if hacks later show that such features work just fine on M1s)).
One conspiracy for Silicon Macs is to try to speed up the upgrade cycle akin to iPhone: motivate Mac owners to upgrade Macs more frequently = more 💰💰💰 for Apple. These "incredible", "fastest ever", "best ever" Macs we are enjoying now are probably 2 macOS updates from starting to get the classic "long in tooth" descriptor associated with them and maybe 1 more away from key features in new macOS "not being able to work with..." We know how this goes. See Silicon on iDevices as a long-history blueprint of how this will likely play out.
So, as an indifferent OP, M2 all the way... and buy third party external storage if you really need the extra 2TB right now. Else, use the 2TB and when you need more, you can easily add it then. Third party SSD will cost much less than Apple's pricing. You'll have those Thunderbolt ports ready for some fast storage whenever you need it. Here's the math on that:
- to turn 2TB into 4TB of Apple SSD is + $600 in the Apple store.
- For the same money plus approx. $200 more (which will still be better than the "stretch" option), OP could add an 8TB M.2 stick to the 2TB option for 10TB of total storage.
- Or if 2TB more is all that OP desires, many 2TB sticks are well below $100 right now, saving $500 vs. Apple pricing.
OP, unless you have an absolute reason in support of Mac Studio, you might want to consider Mac Mini Pro with an eye towards upgrading it in maybe 5 years, when Apple will likely be undermining the appeal of M1 and M2 with macOS updates anyway. What I really wanted to buy when I purchased Mac Studio was the much rumored Mac Mini with M1 MAX at the time. In spite of feeling much love for my Studio, if I was going again right now, I'd probably buy Mac Mini Pro with maximum RAM and as little as 512GB SSD to get over the "half speed" SSD issue... then big external SSD for the bulk of my storage needs.
Another option is a MBpro with M2 MAX (
now getting discounted in many places) and perhaps a dock to easily dual use it as laptop
and desktop Mac.
This dock "coming soon" looks especially good for such purposes.
With rumors of M3 Macs hitting as soon as October, the M2s should see some discounts and refurb pricing to make them even more price appealing as soon as 2 months from now. If you lack a burning need to buy now, you might want to stand by for upwards of 6-8 weeks and see if M3s do show up in OCT. If so, most M2s should show SOME price impact and M1s even more so.
