    Can people with different versions of the Haswell 13" i7 post their SSD speeds?

    I am running 8gig ram 128 gb SSD with over 75GB free and only getting 20o read and 500 Write (FV2 is running)

    ok update:

    With FV2 off i'm getting 300 or so write and a crisp 700 read.
    I get the 100 or so drop in write with FV2 but 200+ drop in read? why?

    The wife's new 13" i7 MBA (8gb / 256GB) gets around 680 write and steady 700 reads. Will verify when I get a chance.

    But ran it to compare to my new SSD (840 EVO) in my 2012 i7 MBP (~ 500 read and write).

    I have the 2013 i7/8gb/512gb, although it's an 11". Not using filevault.

    I get 670/721 read/write with my i5/8GB/256 Samsung SSD, so it's not much less than the i7.

    11" i7 with Filevault. My numbers are comparable to yours. The encryption and decryption slows things down a bit. That's all.

    anyone have a read/write speed for that setup??

    I have a 11/i5/4/128 with FV2 enabled.

    I get 200 write/ 500 read.

    I think the Sandisk SSD suffers a bit more than the Samsung SSD when using FileVault 2.

    yeah this is what i found out after testing and forum-ing :D

    without FV2 its closer the the Samsung 128 disk speeds.
    regardless however even at current speeds it is supa fast :D at least fast enough for me wife... i may get her a 256 drive when those upgrades become available from OWC...

    i went in to the apple store this weekend and played with this exact setup. i think it is fast enough for my liking. not sure is FV was enabled.

    unfortunately i didn't leave the store with it :(

    I think I read somewhere that it has less to do with the manufacturer and more to do with the number of flash chips. The 128GB models have fewer (half?) chips than the larger 256 & 512 models. Since an SSD can write to multiple chips in parallel, speeds would be faster on the higher-capacity models.

    So it's not Sandisk vs Samsung, it's the SSD capacity. It just happens that Sandisk makes the 128GB models.

    I have no complaints. For me, everything is so fast already that the security of FV is well worth the (imperceptible) performance losses.

    I've got the Air configured as shown in my signature. Not got Filevault enabled anywhere, but the 512GB has about 96GB free. Write speed is 711MB/sec and read speed is 727.9MB/sec according to the BlackMagic benchmark tool.

    the 128gb ssd has 300ish write speeds and 700 read. the 700/700 that you see in 11 inch and 13 inch models are the 256ssd and above. it's due to the chips management and how the whole ssd works though in every day works you wont prolly notice any difference
