Do MBp SSD write/read speeds really matter in this case?

    MBp late 2014 256gb with 700mb read/write speed vs MBp early 2015 256gb 1400mb read/write speed.

    My question is at these high speeds will I actually notice any difference and if yes where exactly? (installing programs, starting programs, start time of OS etc). I understand the latter is twice as fast but will I notice it? Will the Yosemite load literally twice as fast?

    No. Only if you do a lot of data transfer.

    You should not be seeing much of a difference unless you more large amounts of data frequently.

    Nope, it wouldn't.

    I've got both a late-2013 13" (i7/16/512) and an early-2015 13" (i7/16/512 as well) and the only situation where I see the difference is Blackmagic benchmarks.

    wow, well that's a precious info...thank you! I can't believe os load times are the same on both machines :(

    I know

    It's so gutting when my 2013 rMBp takes 10 seconds to boot and opens everything instantly.... Booo Hoo Hoo what will I do...

    Boot will probably be a second faster. If you are caching a lot because of lack of ram, it will help. That's about it. 700 Mb/s was already really fast. 1400mb/s was previously achievable only through 4x raid setups, which is crazy fast on a laptop from one ssd.

    It's not about sequential speeds

    these are no biggie unless transfering or writing a lot of data to disk. It's the I/O speeds taht are important for most operations.

    Iʻm just glad were at a point where we can have these kinds of speeds on laptops. Awesome stuff.

    The SSD is not the bottleneck. There's no need to reboot a laptop often anyway. I do about once a month, and it doesn't matter whether it takes 20 seconds or a whole minute.

    The cmbp 2012 that's still on sale today boots in 10 seconds with a Samsung ssd in it too.

    Exactly my point...

    I was being sarcastic. Modern SSD's are just quick, all of them this obsession with sequential read writes is missing the point and almost completely unimportant in most use cases.

    I know you was I was adding to your statement that a 3 year old machine does the same

    My partner has a MBP with PCie flash storage with a read/write around 800 mbps, I've installed an SSD in my 2012 MBP classic with a read/write around 500mbps.

    While I know hers is faster on paper, in practice it's pretty much imperceptible.

    I suppose it's diminishing returns, once things are running at SSD speeds everything's so quick that you're not going to notice a difference.

    Even at 500 mbps on my drive everything's loading near instantly, can't imagine things loading faster, let alone needing things faster.

    I wouldn't worry about it, you're looking at two winners either way.
