Why each option
A hot spare drive can only protect and replace failed drives that have an equal or smaller storage capacity than itself.
A 300GB hot spare can protect a 150GB drive because it has sufficient capacity to reconstruct the data from the smaller failed drive.
A 300GB hot spare can protect another 300GB drive as it is an exact match in capacity, allowing for direct replacement and data reconstruction.
A 300GB hot spare cannot protect a 400GB drive because it does not have enough capacity to store all the data from the larger failed drive.
A 300GB hot spare cannot protect a 500GB drive because its capacity is insufficient to replace the larger drive.
A 300GB hot spare cannot protect a 1TB (1000GB) drive because its capacity is significantly smaller than the failed drive, making it unsuitable for replacement.
