Base 13-Inch MacBook Pro With M2 Chip Has Significantly Slower SSD Speeds (macrumors.com) 85

Posted by msmash from the PSA dept.
Following the launch of Apple's new 13-inch MacBook Pro with the M2 chip, it has been discovered that the $1,299 base model with 256GB of storage has significantly slower SSD read/write speeds compared to the equivalent previous-generation model. From a report: YouTube channels such as Max Tech and Created Tech tested the 256GB model with Blackmagic's Disk Speed Test app and found that the SSD's read and write speeds are both around 1,450 MB/s, which is around 50% slower reading and around 30% slower writing compared to the 13-inch MacBook Pro with the M1 chip and 256GB of storage.

Disk Speed Test app numbers shared by Vadim Yuryev of Max Tech:
13-inch MacBook Pro (M1/256GB) Read Speed: 2,900
13-inch MacBook Pro (M2/256GB) Read Speed: 1,446
13-inch MacBook Pro (M1/256GB) Write Speed: 2,215
13-inch MacBook Pro (M2/256GB) Write Speed: 1,463

Yuryev disassembled the new 13-inch MacBook Pro and discovered that the 256GB model is equipped with only a single NAND flash storage chip, whereas the previous model has two NAND chips that are likely 128GB each. This difference likely explains why the new model has a slower SSD, as multiple NAND chips allows for faster speeds in parallel.

              I used to not understand it, then bought a macbook pro from 2010 ish for testing my multiplatform code on MacOS. Somehow this $200 almost 10 year old laptop had better screen, speakers, and touchpad than my Windows laptop bought just 1 year ago at the time. It's still better in every one of these ways than a new Framework laptop I spent over $2k for. I am now also an owner of an M1 MacBook Air. They aren't overpriced, the money just goes into stuff like keyboard, screen, touchpad, speakers, etc. Anyone who thinks these machines are overpriced has never actually used one. You might think your trackpad is good, but you think that until you actually try using a MacBook trackpad and realize that these things are so good you basically don't even need a mouse. Does your trackpad have force touch? Your screen have a 180 degree viewing angle? True Tone (or something similar that's not an Apple trademark) for the display? A webcam built into the lid that doesn't make you look like you're from Minecraft? A mic array that makes you able to be heard clearly and not need to buy an external mic? Speakers that are crisper and sound better than $80 stand alone external speakers I bought on Amazon for my desktop? A literal 12 hour battery life doing normal tasks? Being able to be kept in a backpack for a week without running out of charge? CPU speed mostly matters for gaming and code compiling, which is not what most people use a laptop for. MacBooks are better value for most people because cpu-speed/$ doesn't capture the value proposition well. These machines are well optimized for "normies". And I say that as someone who had used Linux as their ONLY desktop operating system for around 3 years. Regardless of what you think of the locked down ecosystem, I think you cannot be sane if you claim Apple sells bad hardware. It's not all about the CPU and memory.

            The issue is whether Apple had to resort to a proprietary form factor to get the performance cited. They did not.

        Sorry to Reply to my own Post; but, upon further research, I found that this truly is an issue only with the base model. Yes, TFA makes this clear; but that fact seems to be getting lost in all the Apple Hate. To wit:

        "It appears that only the base model 13-inch MacBook Pro with M2 chip has a slower SSD. As noted in the MacRumors forums, Aaron Zollo ran the Disk Speed Test app on the 512GB model and the SSD's read/write speeds were similar to all M1 models"

            It's easier to build a 256GB unit using 1x 256GB chip and a 512GB unit with 2x 256GB chip than using 2x 128GB and 2x 256GB chips.

            The former method requires stocking only one flash part and your order from Samsung or whoever makes it only has that one flash part. That flash part is cheaper

            • This is really easy to do on the manufacturing line as one chip is always added, and the second chip can be added optionally depending on the mix of boards they want to produce. So if I look at the order sheet and see that 10% are the 512GB model and 90% are the 256GB model, I can tell Foxconn to populate the extra flash chip on 10% of the boards, and to make the rest without it. Whereas if I used two different flash chips, I'd have to tell Foxconn to run the production with one flash chip, then halt the line, change to the other flash chip, and continue production.

              Or, considering that the Flash Storage is (IIRC) the only BTO Option, you could just build Subassemblies with everything But the Flash Stuffed, then do batches of essentially to-Order Final Assemblies, each with the amount of Flash that was Ordered.

Even with their fucking horrible butterfly keyboards, and their stupid touch bar both of which got absolutely slammed in reviews they were making money hands over fist.

                Worst case, Apple can kludge up a daughter board with whatever 128s they can dig up, that can be stuffed onto the logic board layout until they get a new logic board rev. Through layout and qualification. I'm pretty sure Apple would rather do that than shitcan

    • Yes according to the article.

      It appears that only the base model 13-inch MacBook Pro with M2 chip has a slower SSD. As noted in the MacRumors forums, Aaron Zollo ran the Disk Speed Test app on the 512GB model and the SSD's read/write speeds were similar to all M1 models, but getting these speeds will require spending at least $1,499. This likely means that the 512GB model remains equipped with two 256GB flash storage chips.

  • My 2015 MacBook Pro is still chugging along - although I did replace the SSD with a Sabrent NVMe drive a few years ago.

    I've got an M1 Air from work. I can't say that the 2015 feels any slower than the M1, although realistically it must be (at least by the benchmarks).

    • This is kinda my experience with SSDs. The raw throughput offered by a top end m.2 is nice and all, but mostly programs are written such that reading and writing files involves a whole lot of single threaded processing. Your system got a whole heck of a lot faster moving from a mechanical to a SATA SSD largely due to the very low to non-existent "seek" times, but moving from the SATA to the m.2 doesn't yield much over the course of the day. Still, apple should have to warn customers that there's a large per

  • Just upgrade the SSD on your own, the way you can with every other laptop in the world.

  • How can you call something "Pro" if it only has 256G of storage?

    • Why not? What kind of a "Pro" keeps data on their laptop? Are you one of those people who still use their computer like it's 1998 or something?

        If you had two brain cells you'd realise that some pros spend time working 'on location' where internet connectivity may be limited or non-existent.

        A "pro" isn't just sitting around a hotel room watching Netflix on their laptop.

        • Of course not. But what does internal storage have to do with Pros in the world of ultra fast high capacity thunderbolt SSDs?

          A "Pro" by your definition is hardly going to be satisfied with a 1TB internal SSD either.

  • Why do you never need local storage? Thin clients for everyone!
  • It's sad to see that Apple cheaped out on that SSD. One of the redeeming graces of Apple's products has been that they generally don't do that; you're stuck with the built-in SSD, for example, but at least it's a good one.
