All of apple's SSDs are Samsung, by a large margin the worst on the market. http://it.anandtech.com/show/2829/19 http://it.anandtech.com/show/2829/19

Good to know. Waste of a thousand or so $. Was hoping it had changed for this release, but I suppose that's hoping too much.

  The best strategy with Apple is to skimp on everything and upgrade it yourself. The price difference will cover a second laptop if you fuck the first one up.

    This is what I've always done. I managed to keep my first Mac (a TiBook) feeling fresh for 6 years, and my second (a MacBook) still seems basically new at 2 years. But can you do this with the unibody MBPs? The battery's not user replaceable, right? What about the HD and RAM?
    - rbrcurtis 17y ago
      The ram is absolutely replaceable and easy to do. From reading above, it looks like the HDD is pretty easy as well.

    The 8Gb RAM upgrade now is $400 - same price if you buy it on newegg. You could argue that you will still have 4Gb laying around, but I personally have no use for that and can't be bothered to sell it.

      Upgrade retailers like MacSales.com will buy the stuff back from you, so at least it's not entirely worthless.

Samsung's rotating disks are the worst disks I have ever owned. I bought 2 and then 1 more, and all 3 need to be RMA'd. To keep my RAID array alive, I am doing them 1 at a time, and they are not fast. Worst disks ever.

The question now is - how difficult is it to replace a regular hd in this generation of Macbooks? In my 3yr old laptop it was a manageable, although a bit stressful, to pull out the hd and replace with an SSD.
- generalk 17y ago
  Super-easy. I have the first-gen unibody Macbook Pro, and it's right next to the battery as you take the cover off. Just one screw and it's out. I can't speak for the newer, non-user-replaceable-battery models, but I can't imagine they made it harder to replace the HDD.
  - mike-cardwell 17y ago
    Tip. Don't put it in upside down and then push hard or you'll end up having to undo a whole lot more screws.
  - jbellis 17y ago
    "I can't imagine they made it harder to replace the HDD." Start imagining. You need a mini-torx screwdriver to get the hdd out, once you get the cover off (8 phillips screws). Not the end of the world, but not too many people have a T8 sitting around. I didn't.
    - masomenos 17y ago
      I agree that this is a minor annoyance, but your local hardware store probably has one available for $5. In other words, it's still orders of magnitude better than replacing the HD in, say, an iBook.
    - chrisbolt 17y ago
      The Torx has always been required. At least with the unibody MacBooks they made it far easier to replace the hard drive. I just did a pre-unibody MacBook Pro yesterday, you have to pull the entire top part with keyboard.

Not only that. I've been a Mac user for almost 10 years now but I'm waiting for them to add TRIM support to OS X before taking the SSD plunge. Everybody using an SSD on OS X should understand that its performance will degrade more quickly than on another modern OS. It's quite disappointing to me.
- generalk 17y ago
  For those curious as to why performance will degrade quicker on OS X: http://en.wikipedia.org/wiki/TRIM http://en.wikipedia.org/wiki/TRIM Just had to look that up myself. Shocking that OS X doesn't support it natively, although the article suggests there may be utilities that can replace that functionality.

    Intel X-25M has TRIM support in the controller itself, and thats the way it should be I believe
    - sorbits 17y ago
      The drive does not know when data stored on the drive is “deleted”. This is what TRIM is for, i.e. when you delete a file you just unlink the inode. You need to tell the drive that the blocks that the file occupied are no longer needed, so the disk can ignore that data when reorganizing or later rewriting part of the block.
    - 9oliYQjP 17y ago
      Unfortunately while there are strategies to mitigate the problem in hardware, proper TRIM support is still best. You might be getting confused by the TRIM enabled firmware that was released in December '09 for that SSD? It just means that the Intel drive will obey TRIM commands from the OS. But if the OS doesn't send any commands, which OS X won't, then you're not taking advantage of TRIM. For what it's worth, if you were going to choose a drive that would degrade the least in performance without the use of TRIM, you probably chose best with the Intel X-25M. But it would still perform better over time in Linux or Windows 7.

All of apple's SSDs are Samsung This is incorrect; at least with the MBPs they were shipping until today it was a bit of a toss-up as to whether you'd get a Samsung or Toshiba SSD, and the only way to know what you got is to boot up the system and look at the drive's model number in System Profiler. FWIW, the one that came in my MBP is Toshiba, and is still awfully zippy after eight months of heavy use (during which I'm quite certain I've written enough to the drive to start noticing any real degradation).
