What you configured is not a Fusion Drive.

Yes, it is. I'm not going into specifics, but read on it. It's mostly a matter of configuring the drives as one mount in OS X 10.8.2+ (only OS X 10.8 supports it). It's not a "hybrid" drive as I assume you are thinking. There are tons of guides on how to easily use terminal to achieve a "FusionDrive".

Here is a quick link to a thread on MacRumors. I don't have the time to post much more at the moment.

Turn late 2011 iMac with SSD+HD into Fusion Drive

Why not specify the location for Final Cut, etc. on an external drive? I can understand how this would be an issue, as "FusionDrive" is simply an OS X 10.8.2 algorithm in deciding where files are placed based on "learning" what files are used more often and placing those files on the SSD as high priority. I wonder how that is resolved? Wouldn't the HDD portion of the fused drive be used as caching space before the SSD? Seems bad programming there.

How so? It's not like they are each handmade individually? Care to back up your dumb remark?

Got mine before Christmas as well, the display is beautiful. The colours are what I love about the screen. I compared my old 24" early 2009 model next to the new 27" model, the old model looks yellowish in comparison and colours aren't as vibrant. This new Mac is awesome.

Fair enough--I deserved at least part of that. I didn't assume "everyone else" is ignorant, but I still assert that the member in question was making an erroneous statement about "amateur" manufacturing techniques. I also made a rash and uninformed statement, about fusion drives in my case, so I guess we're even.

I ordered my 27 inch on day one (actually a day before it) from a 3rd party retailer my friend works for so I could get a discount. I haven't heard a peep about my computer since Nov 29. Hopefully this means it will ship soon.

Edit: Not 10 minutes after I posted this, I got a text saying it finally shipped from China. Praise The Lord!

It's all good, we're all here to learn and to help others. I just take issue when some people, not meaning you, rudely slam others when we all make mistakes (I certainly have). We all started somewhere, I try to keep that in mind while commenting in order to help, not hurt, others.

Why not specify the location for Final Cut, etc. on an external drive? I can understand how this would be an issue, as "FusionDrive" is simply an OS X 10.8.2 algorithm in deciding where files are placed based on "learning" what files are used more often and placing those files on the SSD as high priority. I wonder how that is resolved? Wouldn't the HDD portion of the fused drive be used as caching space before the SSD? Seems bad programming there.
I was wondering the same thing. I do video work as well, but most of my source footage is located on external drives. I was hoping my new iMac (which hasnt shipped yet) with Thurderbolt and/or USB 3 drives connected will make that work flow even faster.

It's a very good question I'll have to research when I have time. I've spent a lot of time understanding OS X 10.8.2's implementation of "FusionDrive" systems. I know it doesn't use Intel's SRT technology and works mainly through Core Storage and frameworks established in 10.8.2. I'm surprised such a simple situation isn't resolved by using the larger HDD as caching, especially in pro-app's that may need large space for heavy lifting. I have a Mac Pro 12-Core myself, with a 256GB SSD and four internal SATA HDD's so I don't use a "FusionDrive" setup to test with FCP7 or FCPX 10.0.7., but I'm curious to give it a run on a "fused" LVM.

Very interesting...
I'm going to assume that you also have external drives for Media, but that some Media is being written to the Fusion Drive??

I was going to order a 27" using my Federal Tax refund, and was going to order with the Fusion Drive (3TB)... I am also a Video Editor... using both FCP and Avid MC.

I'm sure a Fusion Drive would be fine for MOST applications... however, in your opinion, do you think that an iMac with a Fusion Drive would be a mistake to order, with the troubles you've had with Video files?
Thanks

I wouldn't believe it to be a mistake, as I and you suggested, I would try specifying an external drive as my main HDD in FCP7/X. It seems that OS X 10.8.2 is not caching large volumes on the HDD portion and instead using the SSD (in this specific situation), which it shouldn't. What is interesting is that it should use the HDD first for large files, etc, then once work is completed begin read/writes to both based on priority/space required for files (or really blocks).

Here's a good read through on ArsTechnica, read my posts and the article as it's a good walkthrough on "FusionDrive":

The screen lamination is a feature, making the viewer (you) feel a little bit closer to your content. It doesn't have anything to do with the thickness of the iMac

27 inch iMac

I own a 3.4 GHZ 27 inch iMac with a 1 TB fusion drive and I have to say it is flawless; it's fast, beautiful, and simply amazing. I was hesitant about the new design with heat dissipation being a potential concern but this machine runs stone cold. My mid 2010 27 inch iMac generates more heat. I have not had any problems with the fusion drive at all. I ordered the iMac on the 1st of December and received it on the 24th of December and I have been using it constantly without any issues. I highly recommend this machine!

Seems just the opposite, and yes, that is bad programming. The end results are the problems I experienced.

This just seems like a novice oversight - to not get your supply chain in order before launch but then again i'm not managing a tech giant that creates millions in revenue so take my inference very lightly....

Maybe use the machine normally for a few days before attempting any heavy lifting? Just like you would a brand new car, beak in the engine a bit (although most modern cars do not require this any more, but I still do it).

It's my experience that for video editing, a Fusion Drive will most definitely cause the problems I mentioned. I know the conventional 3TB HDD doesn't have those problems because I tested a Carbon Copy Cloner backup I made on a conventional 3TB Lacie Thunderbolt HDD, and it worked perfectly.

I ordered my 27" (i7, 1Tb Fusion, 680Mx) on Dec 1st through an Apple Reseller and almost 6 weeks later I'm still waiting! I was give an ETA of 3-4 weeks at the time I placed my order!
