Everyone's needs and requirements are different. I appreciate all who posted on this forum about the nand SSD speed issue. I have learned so much, and can now make a better informed choice when buying new Macs going forward. Thanks to everyone who commented, especially those who suggested we look at all SSD speeds stats, such an Random Access speeds, in addition to the Sequential SSD speeds.
While I understand more now why Apple chose to go with single or double 256GB SSD nand chips in all their M2, M2 Pro, and M2 Max Macs, now we as consumers can better choose the SSD nand speed maximum that we want for current and future use of the particular Mac that we buy.
We can choose a $499 educational priced Mac Mini ($599 non-education) if we are on a very tight budget, and settle for an M2 with 8GB of Unified Memory, 256GB SSD drive with maximum 1,500 MB/s read/write Sequential speeds, or for an extra $200 each bump up either the RAM to 16GB, or increase the SSD to 512GB, with maximum 3,000 MB/s read/write Sequential speeds, or do both. Above 512GB on the Mac Mini M2 (Non Pro version) if you increase the SSD to 1TB or 2TB you still get 3000 MB/s maximum read/write Sequential speeds.
If we instead choose the $1,199 education priced Mac Mini Pro base model ($1,299 non-education), then we get a M2 Pro chip with 16GB Unified Memory and a 512GB SSD drive, with maximum 3,000 MB/s read/write Sequential speeds, or we can spend $200 more to get 1TB SSD storage, with maximum 6,000 MB/s read/write Sequential speeds. The 2TB, 4TB, and 8TB model of the Mac Mini M2 Pro will also benefit from the higher SSD speeds. Of course, we can upgrade the CPU to 12 cores for $300, upgrade the RAM to 32GB for $400 more, upgrade the Gigabit Ethernet port to 10Gbps for $100 more, etc. I recommend if we want to get a maxed out Mac Mini M2 Pro model, that we either get a Mac Studio M1 Max model which is now on clearance, or as a refurb, or wait and get a new Mac Studio M2 Max when they are released, as they will see significant GPU benefits, as we have now seen on the MacBook Pro M2 Max models.
We can also choose a MacBook Pro 14" or 16" M2 Pro or M2 Max model now, with a 512GB SSD drive having maximum 3,000 MB/s read/write Sequential speeds, or upgrade to a 1TB or larger SSD model, with maximum 6,000 MB/s read/write Sequential speeds, or we can get a clearance, refurb, or used MacBook Pro M1 Pro or M1 Max model with all models having faster SSD drives in them, without the 3,000 MB/s limitation.
I hope this helps everyone with a summary of where we are, to help us make the best buying decision for our needs.
