How are you going to get better than what Apple is now offering? OWC is your only alternative, anyway. They used to be ahead in speed a few years ago vs. what Apple offered, but not anymore.
Got a tip for us?

Just ran the blackmagic test on my new MBA with the 256 GB flash drive, and got 706 MB/s write and 729 MB/s read.
Samsung, I think. I recall seeing a post about the letters that describe one from another.

Mine says "APPLE SSD SM0256F"
it's a Samsung!http://i.imgur.com/3RijQOv.png
And holy cow, it shows...
Please ignore that, I read "my disk's brand". In order to know your screen's brand, run this command:
If there's an "LP" prefix, you've got an LG screen.

my apologies for resurrecting an old thread, but I just bought my 13" MacBook Air (Mid 2013) (new) and my write speeds on the PCIe SSD is only ~320-ish MB/s and the read speeds are ~700 MB/s and I was wondering why it might be so slow.
I have a SD0128F.
Blackmagic is showing 316 MB/s write. But if I run time -p dd if=/dev/zero bs=1024k count=10240, it comes out to around 330 MB/s.
(And by comparison, my Intel 520 240 GB SATA 6 Gbps SSD reads and writes at sub 550 MB/s).
Any help would be appreciated. Thanks!
(Oh and I'm already running OS X 10.9.4, with all of the latest updates installed).

That's normal for a 128 SanDisk Drive. I have the base model rMBP and my speeds are roughly the same. I wouldn't worry about it. In everyday use you will not be able to tell a difference. The larger capacity drives also tend to be faster. My wife's 2014 13"MBA has a Samsung and it has read and write speeds over 500 and there is no noticeable difference in usage between hers and mine.
The 64GB drives are slow. the 128GB are faster, and then you get faster with the 256gb and real fast with the 512gb. So make sure you compare not only brand but also size
I think the size of your drive is the reason for some of the slower speeds, but that does seem a little off

Well, I was wondering if the performance would suffer more because my MBA only has 4 GB of RAM, so it would likely end up needing to swap more to disk, and so the speed of the SSD will affect the swap performance, since it seems inevitable that it will do that in the future.
I understand where you are coming from as I initially had those thoughts as well but I don't think it is something you will notice. I can take my base model 4GB/128SSD(with slower San Disk) rMBP and put it next to my wife's base model 4GB/128SSD(faster Samsung Disk) Air and open all of the same programs while pushing both machines hard and there is no speed difference to speak of. While they aren't both the exact same machine(one Air and one pro), they both have the same ram and the same sized SSD so in theory they should be similar.
In the end it all amounts to what you are happy with. In my opinion, the San Disk performs greatly and if I hadn't ran Black Magic, I would never know the difference.
Also if you play the exchange game there is no guarantee you won't keep getting San Disk again

Hmmm....
I'm not sure if I would notice the difference or not eventually because I tend to have several HUNDRED Firefox tabs open (the joys of doing research)...so...that tends to tax the system quite a fair bit...(which also tends to lead to a lot of swapping...)
Excellent spatial reasoning skills??? (Loose memory of what they are by position...)
I'd love to see a screen shot. I can't imagine

it's not hard when you're dealing with international law...
I don't think you will have any problems with the San Disk. I am currently on my base model rMBP (4GB/128 San Disk) with 40 active tabs in Safari, 40 open tabs in Chrome, iMovie, Garageband, iPhoto, Spotify, Word, Excel, Numbers, iTunes, all running simultaneously (much higher multitasking than my normal use) and have yet to have any lag or beach ball spinning. I am swapping but still flying as if I had a maxed out machine. I am trying to slow it down but it just keeps going
