    I'm about to bite the bullet on a high-end 13" rMBP soon (the late-2013 base rMBP that I won in a raffle is inadequate for my regular usage, which involves running VMs frequently).

    I'm maxing it out to i7 (I've got plenty of funds to afford the slight speed bump and the slightly larger cache) and also 16GB of RAM (for my usage with VMs).

    However, I've heard that some people who ordered the 256GB 13" rMBPs got the SSDs in two flavors: the slower SanDisk and the faster Samsung.

    I'd like to know whether the 512GB variants come in Samsung-only or not.

    Thank you.

    I have a late 2013 15" with 512gb, but I don't know which one I have. If there is a command to run (such as the one that tells you which LCD you have), I can run and show the results (assuming that's the only way to know without opening up the laptop).

    Go to system report and check out there or even disk utility sm512e is samsung sd512e is sandisk the numbers will represent drive capacity.

    I have the early 2013 sandisk 512gb the difference between samsung on sandisk is negligible when using real life stuff but when benchmarks i found some 10-20mbps difference. Though besides speeds i have not checked the samsung ssd much. The sandisk one does not display a whole lot of smart attribute which would give you a picture of you ssds life.. Things like erase cycle count. Total data written and some more atributes found on other ssds are missing. Though its nothing to be bothered of. Over a period of 7 months my sandisk developed 5 bad blocks.

    Thanks!

    Disk Utility says APPLE SSD SM0512F Media, so I guess it's Samsung on mine.

    13" Haswell rMBP, 2.6 i5, 16GB - Disk Utility says "APPLE SSD SM0512F"

    All I can say is, its blazingly fast :)

    The early-2013 ones are SATA based, so no matter whether they're Samsung or SanDisk, they still can't match either SanDisk or Samsung PCIe in the late-2013 ones :)

    ----------

    Yea, SM is Samsung.

    Are Blackmagic benchmarks around 750/720 MB/s in read/write respectively? I don't expect it to be anywhere near the 900-1000MB/s speeds obtained off my 15" rMBP with 1TB SSD, but I know that the SD ones are slower (tried it on a friend's 13" with SD0256F and did some video editing on it to test the speed, and felt the slowdown compared to a 1TB 13" rMBP of another friend, both with 2.6GHz i5. I did not compare either with my 15" because it'd be unfair to compare a dual-core with a quad-core).

    But bottom line, I haven't tested out a 512GB variant yet (they seem to be pretty rare in where I live). The reason I'm going for a 512GB is that the slowdown in the SD0256F is significant enough to the point that I'm not going for the SD/SM0256F lottery, but I can live on something slightly slower than my 1TB SSD, so ideally, it'd be a SM0512F, which'd be, performance-wise, somewhere in between the SD0256F and SM1024F.

    Can you guys download a utility called smart utility, and post a screen shot of the smart attributes. To see the attributes while in the app click on more info. Just wanted to see if it the ssds show a host of attributes or just very few.

    This is from a Samsung 840 Pro 512GB in my early-2011 MBP.

    Thanks i was looking for the retina ssds attribute. My sandisk ssd shows me about 7-8 attributes if im right cannot verify now its at the AASP since two weeks. As i remeber it was re-allocated sectors, temperaure, used reserved blocks, mwi , power cycle count, power on hours, intterupted power, read erros. Then again a few folks have stated that the marvell controller does not show a whole list of data and thats what the sandisk ssds have.

    I literally just picked up my new rMBP-13 2 hours ago. It has the 512GB SSD and it's a samsung.
    From what I've read, Samsung is the sole supplier of 512GB and 1TB storage. With 128 or 256 you're playing the SSD lottery.

    Right now I'm encrypting my disk with file vault, I was getting 706/730 in blackmagic prior to encryption, I'll retest when it's done (in about 30 minutes).

    UPDATE - blackmagic scores after Filevault2 encryption = 695/721. Very impressive indeed - there's really no reason to NOT enable file vault encryption.


    FWIW I got a BTO model with 2.8i7, 16GB, 512GB

    (still have the old rMBP too- gonna sell it)

    Maybe with the pcie flash. The sata one its either sandisk or samsung for 512. Since you owned the old one any difference noticed while doing your regular stuff also it would be great if you could take a screenshot of the smart attributes of your ssd using the smart utility app.

    Honestly not a huge difference in day-to-day stuff, I mainly upgraded to have a bigger SSD and more RAM for running Windows VM's and using Aperture with a larger photo library.

    The 2012 rMBP isn't exactly slow to start with for normal usage. 8GB memory was a bit confining for running a 4GB VM though.

    What SMART utility are you talking about?

    BTW I updated my last post with the Blackmagic scores after enabling Filevault. It barely made a dent in the read/write scores. Still about double what I was getting on the older machine.

    Do check above one member posted a screen shot. It can be used to monitor the life of your hard disk. Google Smart utility for mac.

    Ahh, okay, thank you!

    I'll be placing my order for the 512GB variant (i7+16GB RAM) within the next few days :)
