Wow, I thought mine was fast, but it's slower than everyone else's above. :(

But mine is BIGGER! :D

512 GB SSD
Model: Apple SSD TS512C
Mfgr: Toshiba

That seems a bit slow, even for the Toshiba. It is on a 6Gbps controller now, and that should give you speeds in the 350-400 Mbps range. In any case, you might try another benchmark, since sometimes a controller can give a benchmark a fit, and thus it won't generate a reliable result. Sandforce controllers in particular seem prone to this. I think it has something to do with how the controller treats compressed data vs. uncompressed data. I've read that the Toshiba is a customized Sandforce.

FWIW here is the 128GB Toshiba SSD in my 2011 Air

Mine isn't a MacBook Air, but I have a 3 SSD RAID 0 in my Mac Pro and it gets stellar results in Aja but lackluster results in Black Magic. It is also due to the compression issue as I am using OCZ Vertex 2's.

Also to note for the 2012 models...there are both Toshiba and Samsung SSDs being used. The Toshiba tends to be used more in the 64/128 GB models while the Samsung is for the 256/512 GB models. This is all per this review:

http://www.anandtech.com/show/6063/macbook-air-13inch-mid-2012-review/4

Another thing to note is....like the OWC drives, which are Sandforce drives, the Toshiba drives in the 2012 models are also Sandforce. So with Compressed data, you will get slower speeds.

Also, if you are using Filevault (which with a laptop you should be), the Samsung drive is going to perform better because of the compressed data.

Interestingly, I got the i7/256/8GB model....it came with the Samsung drive. Using the Black Magic speed test:

Before Filevault:

Write avg: 403.5 MB/s
Read avg: 446.8 MB/s

After Filevault was interesting....speeds went up:

Write avg: 422.8 MB/s
Read avg: 449.0 MB/s

I was happy with that.

As for Black Magic......it's definitely going to show slower speeds with the Sandforce drives. I have an old OWC 3G drive in my Mac Pro......with AJA I get speeds in the 200's....with Black Magic I get pathetic speeds....on par with traditional drives.

I think the Sandforce drives used to be the best....but I think others have caught up.

If so, what kind of results are you getting? They should be slower than you think because it now uses UNCOMPRESSED data for the tests. Regardless, I was just curious what your results were like (regardless of what SSD you're using). It's a free app if you want to check it out.

picture att. is this a good speed?

I have a 2TB Western Digital My Book Studio for my iMac (2013 Model). The Western Digital My Book Studio is plugged in via Firewire 800 (with a Thunderbolt adaptor to plug into my iMac).

The My Book Studio isn't a plug n' go. It's a high powered hard drive (7200 rpm?)

But I've ran the Blackmagic Disk Speed Test with 5GB stress test for about 2 minutes and here are the results...

https://dl.dropboxusercontent.com/u/6098795/DiskSpeedTest.png

60.9 MB/s Write, 37.7 MB/s Read. Also, under Will it Work? It says i'm only capable of working with PAL and NTSC. I have an 'X' on absolutely everything else. I've been editing 1080 60p footage off this drive for at least 2 years now without a hiccup.

Are these Write and Read speeds correct? Am I really not capable of editing ANY hd footage EVER according to this app? I feel like it's not working but i've never heard of a person ever have this problem so i'm stumped.

Just got my new Mac Pro hooked up and ran some comparisons between my 2008 Mac Pro and the new one I just got:

Very nice... but did you notice that you're posting in the MacBook Air forum? :)

Doh!! Nope - got here through a google search and just saw the BlackMagic title :)

Even now on my iphone it is hard to see the MacBook Air designation... Sorry about that!

Oh, no problem, just thought it was worth pointing out. I get 700MB/s write and over 700MB/s read on the 512gb SSD in my 11" MacBook Air. Not bad, considering the price difference with the Mac Pro. :D

Those results from your 2008 machine seem kind of low. Just ran the Blackmagic test on a Seagate Desktop Backup Plus drive connected to my MBA through Thunderbolt. This is a 2TB 5400RPM drive, and I get 195MB/s write and 196MB/s read.

Yep - that PCI Express Bus is FAST! Glad to see the Airs are taking advantage of that as well!

Yea - not sure about why the speeds are so low on the '08 machine... Was expecting faster myself!

I d/l the speed test today for a look across all three of my machines.

First up is my Mac Mini 2010 Core 2 Duo / 500G Crucial SSD / Crucial_CT480M500SSD1

Speeds certainly look on the low side, I'd value a more knowledgable opinion.
With thanks

It looks about right for Sata II speeds that come on the 2010 Mini. You need a machine with Sata III to get anywhere near the advertised speed for that drive. And you need a modern PCI Express connection to go higher then that.

OK that makes sense, its not as though I'm not impressed by the speeds on the mini compared with when it had the old spinning disc. Just got thrown by some of the other results as posted here.

So I'm guessing that the same can be send for these results taken from my Macbook Pro 8.2 / I7 2.3 / 16G RAM. This has the BTO APPLE SSD TS512C 500G.
What surprises me most of all about these results is there worse than on the Mini. Though guessing its because the SSD came out a few years previous?
