  • Entry level M2 Mac mini, 2023 MacBook Pro have slower SSD than predecessors

    iPhonedo has an M2 Pro Mac Mini with 1TB ssd.  He gets BlackMagic results that match the M2 Max MacBook Pro speeds.

  • Entry level M2 Mac mini, 2023 MacBook Pro have slower SSD than predecessors

    It seems like all current 40Gbs Thunderbolt 3/4 external enclosures can reach at most just under 3000 MB/s using a fast drive like the Samsung 980 pro (which can do almost 7000 MB/s inside a fast computer) when plugged into a Thunderbolt 3 or 4 port.  Enclosure compatibility varies by ssd brand.  Samsung 980 pro seems to be one of the standard ssds that enclosure manufacturers design their products for.

    Some typical speeds from reviews on Thunderbolt 4 enclosures from Amazon using Samsung 980 pro:



     

    Versus a Samsung 980 pro inside a fast computer:

    If Apple's nand speeds are going to be all over the map,  it might be best to buy from Apple, try and return if the speed sucks.  How many times will Apple allow returns per item?
    The Tom's Hardware test is using 2TB MacBook M2 versions that Apple sent them.  Are they using faster chips in the 2TB models than the low spec (and Mac Mini) models?

    Where did 9-5 Mac get those low BlackMagic 14"M2 Pro MB (3150 MB/s) test scores compared to Matt Talks Tech (6300 MB/s)?  Supposedly they both used 512GB models. 

    If one buys the 1TB M2 regular or Pro Mac Mini will it have BlackMagic scores in the 6000 MB/s  range or the 3200 MB/s range?

    "The M2 Pro chip starts with a 10-core CPU and 16-core GPU, 16GB of unified memory and 512GB of storage. Apple sent us a version to test that costs an obscene $4,099, but it offers obscene power to match with a 12-core CPU, 38-core GPU, 64GB of memory and 2TB of storage. 

    Thanks to our sister site Laptop Mag, we also have the test results for the M2 Pro version of this machine, although this is a pricier configuration than the entry-level model. It offers a 12-core CPU, 19-core GPU, 32GB of RAM and 2TB of storage for $3,299."

    Apparently the M2 Pro Mac Mini base model (16GB ram, 512GB SSD) only has a single 512GB Nand chip.  However the 14" MacBook Pro has a 256 nand chip on either side of it's motherboard in the 512GB ssd model (maybe*).  So the 14" MacBook Pro gets almost double the disc speed in the Blackmagic test because it's in a raid configuration (maybe*). 
    Here's the motherboard of the M2 Pro Mac Mini (single 512GB chip in green rectangle).  It looks to be flat on the table - no second nand chip on the other side.
    Thanks for sharing that link, it was very informative.  However, I believe you are mistaken about the NAND chip on the Mac mini.  They show both sides of the M2 Pro 512GB board, and you can see very clearly that there is a chip on both sides, meaning that there are 2 NAND chips for the 512GB model, not one.
    Oh you're right he did photograph both sides.  So Apple is buying slower chips for the Minis?  And sometimes they get used for the 14" MacBook pros, too?  Sometimes not, like in Matt's test?
