The SATA interface offers a much larger physical space so larger drives are possible! Just looking at HDD’s the largest is a Western Digital 3.5” 15 TB and the largest 2.5” SSD is a Samsung 30 TB both are server drives. I’m sure larger drives will be coming out in the future but there is a limit of return! These larger drives won’t be cheap and how many people need this depth of storage? Not many, at least not now, maybe in the future. There is an extended version used in servers which offers 7.6 TB of storage for $1400! These are too big for PC’s.
So far Apple or even M.2 blade SSD’s are both limited presently to 4 TB due to the physical limits of the chips that fit on the blade drive. Ha! Tell your Apple Store friend to do a bit of reading! The Ultimate Guide to Apple’s Proprietary SSDs & Volume size limits under HFS and HFS+ & Hitting the limits of APFS is both easy and confusingįirst the PCIe/NVMe interface does not limit the size of the drive only the physical limit of the blade holds it back. (i think the price of 4tb ssd was simply too high when apple made the specs.) but it did leave me uncertain. elsewhere, i have seen 4tb ssds that are within my budget.Ī staff member in my neighborhood apple store said that the reason apple does not ship imacs with ssds larger than 2tb is that the connection bus only allows up to 2 tb. the ifixit upgrade kit optionally comes with ssds ,but only up to 2tb. i would prefer an ssd, but i have a lot of data (photos) which i would rather not offload to an external drive.
naturally, i have been studying the hard drive replacement/upgrade instructions. the drive has started failing, forcing me to restore from backups, twice this year.
I currently have a 3tb fusion drive installed in my late 2013 imac, and it’s almost full. My question is this: does any of you knows of any hardware/firmware/software limitation of this imac that will prevent it from operating with a 4tb ssd installed? has anyone here successfully made such a replacement?
