Wondering all you out there who chose the 768 such as myself, have any of you done a speed test on your ssd? what have your results been? I have a macbook pro that i recently installed a samsung 840 pro ssd 256 gb, installed 16 gb ram as well...i get around 500 read 520 write on average from the samsung using black magic disk reader...So i must say i am a little "annoyed" for lack of better word ( because i do love my iMac and the speed) that the my iMacs 768 gets around 435 read 455 write on average...Now that being said its only a difference about 2 seconds on startup time and negligable difference as far as daily use...Im just saying its a little annoying paying 1300 bux and getting slower read and write speeds than pay 250 bux for my 840 pro and getting faster speeds...Anyway thanks for listening and if im out of line for all you mac lovers im sure youll flame on lol...peace!
 
anyone else got these speeds as well? I think i saw somewhere before someone put up a screen shot of around the same numbers....wheres all my 1300$ club members? probabally working to pay for their ssd lol...jk
 
Well I think you hit the nail on the head... in real world use, those are both blistering fast speeds and most users would have a real hard time noticing the difference.

In some tasks people have a hard time telling the difference between mechanical HD and SSD.

Keep in mind that Apple probably began development of the late 2012 iMac almost a year earlier and test the hell out of parts, so they likely specced a very specific blade SSD as the upgrade option in the 2012 iMac, even if later/greater SSDs have arrived on the scene since then.
 
Sounds about right ... do you realize what a 840 Pro might cost if it was available in a 768GB single drive size in todays market? Probably much more than $1300! OCZ has a nice 1TB unit ... for $2500!

I am currently running mine with the 768GB internal SSD devoted to OS X and Windows. Then, I attached a Promise Technology Pegasus J4 Thunderbolt enclosure where I have created a 1.25TB Fusion drive and a 2TB Time Machine Backup. I use the Fusion drive for archive documents, older programs, archive downloads, misc. stuff, and large slow music, video, and movie storage. The J4 is really tiny (uses 4 laptop sized drives), cool, and quiet with 1 Samsung 256GB 840 Pro SSD and 3 ea. 1TB 7200rpm hard disks. I am really pleased with this setup!

Anyway ... here is mine with 4GB test file size:

Blade ssd' are just not as fast as full size 2.5 ssd are. That is why I went fusion, it gives me the opportunity to upgrade to a 1tb 2.5 inch ssd in the future.

yup looks just like mine, and yea your right, i realize that price wise...I was talking more along the lines of the speed...Glad you have the same numbers as i do, i basically wanted to make sure mine seemed to be in the normal range because i had been use to the samsung read and writes and when i initially ran the speed test on my imac it seemed a little off.

----------

I seriously doubt the 840 Pro boots up 2 seconds faster...[/QUOTE

yup it most definately does, i tested it for myself numerous times, and like i said im not complaining, 2 seconds here or there i could care less, i love my imac and the ssd and if i could do it all over id buy the ssd again, i just wanted to know if the speeds were in the normal range for what everyone else had been getting because yes the samsung 840 pro is most definately faster albeit very nominal in the grand scheme of things.[COLOR="#808080

thats a really cool way to setup your mac by the way...I never thought of that...I dont have that much to store as of yet, but i might have to steal this idea from you in the near future
 
Fusion ...you know you get more noise from HDs, more heat, and also constantly waiting for the HD to spin up. With all SSD this is a thing of the past. I'm enjoying my late 2012 SSD iMac very much, thank you. :)
