Im very happy the the read speed of my 2tb fusion drive, looks like it is on par with ssd only systems if I'm not mistaken.

It is on par with SSD systems (because it has a SSD) until you exceed the space of the included SSD.

The write speed is slow in my opinion. On a SSD only system the two speeds are close, and here the write speed is an anemic 1/3 of read.

Maybe, but if you compare it to the previous iMac, write speed is as fast as the old read speed. So I'm still happy with the results. I don't have over 60 gigs on any off my other macs is drive. So I'm thinking about splitting the drives to maybe get better read speeds.

That's about what I'm seeing with my 3TB. Really, the Fusion is a nice compromise of price, performance, and capacity.

Write speeds, though not as fast as the new SSDs, are still screaming! And most of us would be really hard pressed to find something that'll read that fats, so writes wouldn't be the bottleneck. The important element is how much the very minor performance difference will impact your life. After three years with a Fusion 3TB, and with loads of other SSDs, I say not much at all.

I think most of the people out there complaint about Fusion drives have never owned one. After almost three years with a FD, I ordered one again with my new 5k. And I love it!

Congrats on the new system!!!

Yeah, I love my new iMac. So much hate and negativity towards the fusion drive. At least I have the bigger 128 instead of the 24.

I just got my Mac today. Boot is under 10 seconds. Wake from sleep about 3 seconds.
Thanks for the reply. I have been debating the 2TB fusion vs 256GB SSD for days. Mainly using iMac to edit RAW files and the fusion might be the better choice after seeing your results. I really don't like the idea of managing external drives despite so many recommending SSD only.

I have a nmp also with 256 gb ssd 745 write and 950 read so I'm pretty happy with this new fusion drive.
