    Hi chaps,

    Out of pure curiosity, I'd love to know the performance of varying drive capacities in PCIe-equipped Macs.

    Since the rMBPs have all sizes and capacities (the iMac lacks the 128GB variant and Air lacks the 1TB variant), I opted to post this thread here.

    So here's basically the results that I'd love to know for these drives:
    SD0128F (SanDisk 128GB)
    SM0128F (Samsung 128GB)
    SD0256F (SanDisk 256GB)
    SD0512F (I always thought that Samsung was the sole supplier of the 512GB, but it turns out that some owners have the SD version of the 512GB, so I'm interested in this drive)

    So far, I've these results from my own Macs, posted in read/write speeds (all MB/s)

    SM0256F: 720/670
    SM0512F: 750/720
    SM1024F: 950/1035

    I know there's going to be a handful who're going to laugh me off as a lunatic, but hey, we all have quirks of our own, don't we? :D

    There is a thread with all this information in here.

    I've posted in that thread before, but what that thread lacks is that quite a number of posts don't include the model of the SSD (i.e. SM/SD) :(

    SD0128F (PCI)

    Write: 310.5
    Read: 667.1

    That’s using the blackmagic speed test app. If I keep the app running the speeds are different every time basically. Almost gotten to 700 on reads, for example.

    ----------

    I'm a little curious about the SM0128F... maybe someone will post. :)

    SD0256F, PCIE

    720/570 read/write (highest reading, Blackmagic)

    This is measured from a running system, so there is always some activity slowing it down. But I don't think this SSD goes any faster.

    Looks like the general trend is that SanDisk makes inferior SSDs compared to Samsung :p

    I've got a couple of friends with late-2013 rMBPs (256GB SSDs), only that one of them had Samsung and the other had SanDisk. The difference is slightly noticeable during boot up (the spinning circle doesn't appear at all in the rMBP with SM0256F, but the spinning circle spun twice on the rMBP with SD0256F before entering the login screen). Although the delay was perhaps about 2-3 seconds, it was enough to irk the guy with the SD0256F.

    Meanwhile, in tasks with heavy writes, the SM performed noticeably faster than the SD.

    This comparison was pretty fair because both had a configuration of 2.4/16/256.
