Hello, and good day! I have my iMac 2011 27” Running 2 Samsung 250 GB 860 EVO SSD’s Running RAID 0 and it’s kick ass!! I love it so much that I’d like to do something similar with the updated model. Which 27” iMac model will work here? 2012-2015 i7 3.4 MHzBe the best bang for the buck?Retina is a must or 5KMemory doesn’t matter asUpdate it myself only if PossibleVideo card two gigs or betterDrive doesn’t matter as I will Upgrade on my end.. And lastly how much you think I can get on my set up already as I’m going to use the proceeds to fund my new project? 2011 iMac Intel i5 3.1 MHzAMD 1 GB Graphics card24 GB of memory2 Samsung 250 GB 860 EVO SSD’sRunning in Raid 0 500 GB totalRunning Sierra Is still not officially supported that’s a whole Other matter Lol.. ATT: Dan Please feel free to jump in. As you were the reason I started this Project. Thanks in advance. John,
Sadly, you really can’t run RAID internally with the 2012 and newer iMac’s. The reason is they don’t have dual I/O ports which run at the same data rate which is a requirement for RAID to work well. But you could use an external RAID drive subsystem via Thunderbolt2 or 3 (depending on the model) The best option for I/O speed internally is going with the new iMac Pro there you have a dual channel all setup and is doing RAID 0. Basically, you have the best iMac for internal RAID now! While it’s only SATA III (6.0 Gb/s) it still smokes! Save your pennies for the iMac Pro ;-}
iMac mid 2011, try to do fusion drive Samsung 860 EVO - error, don’t work, try to do additional driver to CD-ROM cable, sometime iMac see SSD sometimes fully missing, so i spent 2-3 days, than i thought SSD broken, check it for all test on another PC computer all work well, try again iMac - no result don’t work and all. So i have do conclusion iMac mid 2011 27 inch don’t work with new samsung 860 EVO 250GB , by the way still work my fusion drive at my old 250GB Samsung EVO 840.
