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

    CalamanderCalamander
    Let's talk about real world speed...

    Blackmagic report 5,000 MB/s

    Real life folder - 10,000 items, 4.4GB 


    Manually tested this, it took 37 seconds to copy - translates to 120MB/s

    That's around 40x slower than the max speed

    So I am thinking in real life, the SSD speed is not the bottleneck for almost all operations, except maybe speed tests and things that work with huge volumes of data. Video,, 3D, and so on.

    For the rest of us - we'll never notice if the SSD is 1,000 MB/s or 5,000 MB/s because either way the Finder is limited to 120MB/s for some reason.

    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*). 

    Thanks - the comments on this article should probably replace the article wholesale - they're way more informative. 

    I can imagine Apple not being too fussed about non-pro disk performance, since these SSDs are crazy fast regardless, and you won't see that speed in real life.

    I always have iStat Pro on showing HD speeds and of course if I copy files where it takes a while, I take a peek

    I have never seen speeds exceed 150MB/s in real life (hundred 50)... nowhere near the 5,000 MB/s this MacBook Pro 16 with M1 Pro is supposed to be capable of. 

    So I am guessing that this raw speed is highly theoretical and probably only applies to specialist software applications, ie, moving editing. 

    Otherwise, the file system overhead prevents these numbers from getting anywhere even close to 1,000. 
     
    Unless this was in Mbit/s... which I doubt.. MB is usually Megabyte (8x Megabit)...

    Try it  - copy a folder with 100k items and see how it performs. 

    I have no problems with SSD speed by the way - in day to day, that's never a bottleneck. Only when really copying very large folders does the progress dialog even pop up. Most of the time everything is instant.

  • Apple launches new Apple ID, iMessage, iCloud security protections

    Third-party hardware security keys—it’s about time. I used RSA token hardware 29-30 years ago. I would live an Apple “copy” of RSA’s rotating keys using an iOS app connecting to an Apple server. 
    FWIW All RSA devices were compromised at some point. All hardware devices had to be replaced. 

    Likely today all these contain state actor backdoors, which then are obviously also found by other actors... 

    That being said, 2FA is a good thing in general, and I am pretty sure Apple will do a good job on it. 

    The most interesting statement up there is about state actors. Apple realized in 2013 with the Snowden files that all their servers were compromised. The NSA literally had a backup of every single server at Apple and google, and could do that very easily by intercepting traffic on the backbone which corporations used to sync data across data centers. 

    I remember one of Apple's senior members saying - our security was designed to defend against hacking groups and botnets - not against state level actors! 

    I would think Apple would actually try, and potentially succeed making iMessage impenetrable by state adversaries, also their end to end system is basically the best on the planet. No one else has end to end security that works as seamlessly as iMessage. 

    Whtsapp and Signal lose all history when switching devices or when a device is lost - Apple has E2E that can onboard and offboard devices without losing data. That's really impressive. 

    I guess the main threat to Apple devices at this point is the endless flood of new zero day exploits. I don't think that can be fixed - millions of zero days still lie hidden in code that is sometimes many decades old. Other than rewriting their entire stack from scratch, there's no way to find all these before hackers do. 

    Maybe that's what they should do? I mean they have 100s of Bns in profit a year...

  • Kanye West confused about banks, Apple Pay, and FCC

    To everyone thinking he is mentally unstable - what I don't understand is that you repeat this claim, which is made in the media, but you do not check if it is actually true. 

    There are many 1 hour+ podcasts online where Ye recently spoke with people. Like in the last month.

    In these hours, Kanye comes across as someone who is a genius. Most people don't understand what he's saying because he's so far ahead, and because he picks up so much that people are oblivious about. 

    You can agree or disagree with what he is saying but there is no question he is sharp and awake.  

    When he was on Rogan, that was different, he was still pumped full of drugs that time. He was near death. But now, he's alive and aware. A truth speaker if there ever was one. Unlike other people he is not intimidated, and he doesn't back down.

    Yeah the mainstream narrative is he is crazy. 

    Same as Andrew Tate - can't listen to him because he's a misogynist. 

    The truth is, anyone going against their handlers in the entertainment business is either declared crazy, or put on drugs, or suicided. 

    Just ask Avicii.
