Why are there 1TB micro SD cards that are the size fingernail and most 1TB hard drives are bigger than my hand?
In: Technology
In SD card technology software on the phone or device acts as the hard disk controller allowing the physical chip to be smaller.
In an SSD hard drives a motherboard which also contains the NAND chips acts as the controller. The SSD NAND hard drive is also a slightly more advanced NAND storage medium (think extra features) requiring a larger die size.
