Fusion & Flash Storage
I am not asking about performance. I'm not asking about how any software works. I am asking about the physical components installed in the iMac 27" w/5K Retina display.
Some say Apple's machines are not designed to be opened. They are not designed to be upgraded. That is not the topic. If something is cost effective is not the topic. If something is time consuming or hard is not the topic.
This is a hardware site, other sites do reviews and software Q&A.
If I order a Fusion Drive for a iMac 27" with 5K display, I can get a 1TB HDD and 128GB of solid state flash storage. AKA the meaning of Fusion via it's marketing words.
If I order the non-Fusion Drive, I can pick the storage capacity I want, but for this case, I pick 256GB of solid state flash storage.
So now there are 2 storage options (fusion or flash) to compare which comprise 3 different physical pieces; 1TB, 128GB, and 256GB.
I'm not asking about speed, performance or capacity, or which is better or worse. I am not asking about the spinning hard disk.
The 128GB of solid state flash storage connects to the logic board (obviously), so does the 256GB.
is the only difference between the 128GB of flash storage (available via "Fusion" configuration from Apple)
256GB Flash Storage, the fact that the capacity of 256 is twice 128?
I am asking about how the flash storage connects to the logic board. I am asking about what chip sets are used to make up the final capacity (128 or 256).
As seen here:
For above, in Fusion configuration, the memory chip is SanDisk 05131 016G 16 GB NAND Flash (8 x 16 GB = 128 GB total)
Maybe not a SanDisk chip, but the specs, connection, etc. are they the same between fusion solid flash storage and non-fusion solid flash storage, both PCIe blade?
True or False (question 3)
A - Order Fusion Drive iMac 27" with 5K display
B - Remove spinning hard disk drive
Order 27" w/5K with 256GB Flash storage option
does above situation 1 minus 128GB = situation 2? Am I missing something with this?
True or False (question 4)
If I order 27" iMac w/5K and get the 256GB Flash Storage option, there is no physical mount or retention device included in the machine to allow for a standard hard disk to be installed?
True or False (question 5)
If I order 27" iMac w/5K and get the 256GB Flash Storage option, there is no SATA connector available on the logic board to connect a SATA storage device later?
True or False (question 6)
The logic board is unique based on the the flash storage option? (I don't think this is true, but some have said the flash storage is soldered). So this is really 2 questions...
True or False (question 7)
For either Fusion or non-Fusion the solid state flash storage connects to the logic board using an Apple proprietary connection and not a mSATA?
True or False (question 8)
Order a 5K iMac with Fusion option.
Remove internal rotational HDD.
Remove internal 128GB solid storage.
Install of 3rd party SSD not possible without some retention device?
True or False (question 9)
Order a 5K iMac with 256 flash storage
Flash storage fails within warranty
Return for repair
unplug broken 256GB apple proprietary PCIe blade
then plug-in new 256GB blade
Could a 512GB/1TB blade be installed rather than the original 256GB? (of course apple does what they do, but what would make sense based on the machine's internals)
I know many people are talking about the design and the 5K. I know people are not talking about RAM because it can be upgraded at will. Because the processor isn't fixed to the logic board, there's not much conversation there.
No one is really talking about storage. Why? Is Cloud storage what's needed? Is thunderbolt so fast that nobody cares how much internal space in within the machine?
Bu iyi bir soru mu?
