Just curious, anyone know if you can get the Fusion Drive and actually disable them to make two separate drives? And is the Fusion Drive bootcamp capable? I'd much rather just have a 512 gig SSD, but that doesn't seem like it'll be an option.

Yes, you can use the command line (not Disk Utility) to split up a Fusion Drive into separate SSD and HDD.

Yes, you can bootcamp a Fusion drive, but you only get a partition of the HDD. No SSD will be available to Windows.

In 3-4 years I may be laughed at for having a hard drive on my system.

I know it's going to be expensive, but I want the fastest means of launching all my programs. I don't think, with 400GB of content, that a Fusion drive is going to be the answer.

Maybe I am completely wrong.
You probably don't have 400gb of programs, you probably have 400gb of data. The entire point of the Fusiondrive is that you get most of the performance (boot speed, launch time, etc) of an SSD while still retaining the large storage capacity of a traditional HDD.

By buying a large SSD now, you're getting hit with huge Apple margins on a very expensive component that will be rendered obsolete much faster than all of the other items in the system. Its just not a good investment, especially in light of the performance of the Fusiondrive solution.

As the FD operates at a 'block level', wouldn't that constitute lots of small files being moved around?

While I understand your argument, it's hard for me to completely agree. If iMacs were user serviceable, things would be different. I hope the fusion drive is only a temporary product - after a period of time SSD will replace spinners completely. We're in the period of transition right now.

I see your logic, but I want pure SSD so badly!

Just to clarify, Time Machine will only backup changed files after the first backup, keeping all versions until the backup drive is full. Once full, Time Machine will delete the oldest versions from the backup drive to make room for newer.

There is nothing about Fusion that will avoid moving small files to HDD as space is needed on the SSD for more frequently accessed files.

The OP was worried about watching for a disk full condition, and as you said, Time Machine will manage that by removing redundant old versions of files to keep enough working space.

Furthermore, Time Machine will notify you when your backup disk actually becomes full, such that there are no historical-versions of files that can be removed in order to add new backup data. Fortunately, I haven't hit that point yet.

I tried to add 1.3 TB to my backup raid system last night which only had 850 GB of space available. Time Machine worked for quite a while "cleaning up" the drive system to make room, then faithfully backed up the 1.3 TB of new files.

Time Machine doesn't keep duplicate versions of files. Once the backup disk is full, TM will purge older unique versions. I've hit that point a number of times and the system clearly stated what it was doing at the time.

It did notify you before removing files which were the last version of that file which would then be lost forever? That is good to know.

I misspoke above with "duplicate versions" as I meant "historical-versions", i.e. where there were newer versions of the same file still in the backup.

Serviceability, for me is the ultimate deciding factor here.

I don't want to be stuck with a Hard "Disk" Drive Dinosaur in my computer for the next few years.
Purchase the SSD/HDD combo "fusion" now and you're stuck with it.

Putting cost aside and looking at it more from a technological perspective, the HDD combo will be rendered obsolete much faster than a pure Solid State Drive.

Ummm... after, not before, sorry. Click on Options at the bottom of the Time Machine Sys Prefs and you'll see a check box to "Notify after old backups are deleted" (or not notify you, if unchecked).

OWC has had a turnkey program (and still do) for installing their stuff in your machine. Of course it costs a little more but it is worth it and your warranty does not get voided. You can even get your mac delivered to them directly so you do not have to worry about boxing it.

Fusion for $250, Full SSD for $1300. So, yeah, that.
