I just want to kindly ask if you use both 768GB and Fusion which one is better?
I'm really confused about that.
I'm use C4D, After Effects and Final Cut ProX and i really need something to do that without any glitch.
I suspected fusion drive is not enough for to this kind a 3D and MotionGraphic jobs.
Thanks...
Fusion is, and will always be, a
compromise compared to an all-SSD configuration.
It is a clever software integration designed to give some or most users a better experience than that of a hard disk only environment by providing most of the speed of a SSD along with the inexpensive capacity of a hard disk. If the piece of data you need is on the SSD, it will succeed, but you will notice the difference when it has to fetch the data from the hard disk.
The experience is much better as the
ratio of SSD / HD increases, and the DIY Fusion drives I have running with large 512GB SSDs joined to modest 1 or 2TB hard disks perform pretty well, but I only use them for secondary storage, preferring all-SSD for my main workspace. It is unfortunate that Apple only provides a single small 128GB SSD option for the Fusion choices, but that did, arguably, help to keep the cost down.

It's actually not crazy this time, amazingly. Right now, today, OWC's 6G 480GB SSD drive is $600, and their 240GB SSD drive is $300. Add the two together and you're at par with Apple's offering, which only takes up one slot (and a card SSD slot at that, not a SATA bay).
Which reminds me, you can still add an HDD if you get the 768 card, right? Like let's say I get a 4TB SATA and drop it in there, and set it up as a 4.7TB Fusion. That should work, right?
As far as I know, the 768GB SSD iMacs don't have the
SATA cable assembly which attaches to the drive, although they do have the SATA port on the motherboard (I have seen no tear-downs of this model to confirm this either way). I would imagine that simple cable will become available as a part from the normal sources in due time and should be simple to install.
If you look at the excellent tear-down post with pictures provided by R.OG, you will clearly see the SATA drive cable, which is a standard SATA disk power/data on the drive end, and standard SATA data but special power connection at the motherboard end. There is an Apple part number for this cable, but I have not found the cable available as of yet from the typical sources.
