The 1GB stress test looks like this afer a few seconds:
Simply create a "test" folder on your drive at the top level and point BlackMagicDiskTest to that location for testing. Or you can pick a folder in your user directory such as "downloads" for testing. The BMDiskTest simply needs read and write access which it doesn't have for system folders.
Yep. People need to realize that for drives that can write above 1000MB/s, 1GB test files aren't enough. Soon, 5GB won't even be enough...

Fitted the Sintech adapter today with an Apple 1TB (MZ-KPU1TOT/OA6). Happy enough with the speeds (I had loads of apps open) but better still, the native trim and the price I got it for 
The Sintech adapter seems to be better designed that the Bplus one. I didn't like how the blade was bent when the screw was tightened on the Bplus. The Sintech mounts the SSD blade raised from the card itself and it seems to sit without bending. Much better.

Is this for the 1GB or 5GB test?
5GB but it just seemed to loop so I stopped it. Doesn't seem like the usual tests. Am I meant to wait for it to stop? It seemed like a infinite loop :\
Hi handheld, thank you so much for the work on keeping this thread updated. Really appreciate it. I started a related thread here (unwittingly):

I really need a larger capacity SSD (at least 2TB) and OWC has this coming up for sale:
https://eshop.macsales.com/preorder/OWC-Aura-SSD-for-Mac-Pro/
I know it's not the fastest stick available, but it's fast enough for my needs and more importantly, it does 2TB.
Hoping you could answer a couple of questions:
(1) Is there any reason you think that the OWC 2tB Aura wouldn't work with one of the PCI adapters you linked to above?
(2) Do you know of any PCI adapters that would take 2 or maybe even 4 sticks (Do a simple hardware raid with them like the OWC accelsior card) so that you might be able to get a 4-8TB bootable SSD on a single PCI adapter?
Thanks for any help/feedback, and sorry if some of this was answered in this thread and I missed it.
Does anyone know the max. transfer rate of the MZ-JPU256T/0A6 or MZ-JPU512T/0A6 in a x4 adapter?

I didn't bother with it as it seemed to be really low as others have found. Apparently 5GB is the better test (and default).
Did another run this morning:

On the left is a single 250gb Samsung 840 SSD on a velocity PCIe card and on the right is 2 250gb Samsung SSD's on a Sonnet Tempo PCIe card in RAID 0 striped (32kb). Am i getting the right kind of speeds?? it looks comparable as its made a logical step from the single SSD speed?? appreciate any ideas?
If it isn´t the Pro-version of the Tempo, your result seems OK. As far as I can recall, I got 7-800 r/w with the Pro @ 2*Intel 335 in my former MP 3,1.
New from CES
Aside from the incoming Samsung SM951 two more Mac compatible m.2 SSDs will be available in the first quarter or a little later.
The first is Plextor's successor to the not so great M6e. The M7e promises 1400MB/s read 1000MB/s write. Slower than the SM951 but the Samsung cards are topping out at 512GB whilst the Plextor's offer up to 960GB capacity.
Kingston entered the m.2 format SSD market last year with their SM2280S3. But performance was no better than SATA 3. They aim to rectify that now with the ridiculously named Kingston HyperX Predator which will match the M7e's performance and capacity.
So the question is will you go for the SM951's speed or the capacity of its competitors?

OCZ, Mushkin, Intel - no Mac drivers for the controllers they use on PCIE SSD devices. A shame because them three produce the fastest drives. They work in Bootcamp Windows 8.1 as storage devices though, being obviois here because almost everything works in Windows.
