The best choice for very large storage capacity that is also fast and relatively inexpensive is a hard disk drive (HDD).

Hard disk drives use magnetic storage to record and retrieve digital information. This technology allows them to offer large amounts of storage space at a lower cost per gigabyte compared to solid-state drives (SSDs), which can be much more expensive for the same capacity. While SSDs are typically faster than HDDs due to their lack of moving parts and use of flash memory, the price for larger capacities can make HDDs a more economical solution when vast amounts of storage are required without significantly compromising speed for tasks like bulk data storage.

On the other hand, flash drives and optical drives generally do not offer the same level of capacity as hard disk drives. Flash drives are portable and convenient but are typically limited in storage size for cost-effectiveness, and optical drives (like CDs and DVDs) do not provide the capacity and speed that HDDs can offer for larger data needs. Thus, for a combination of very large capacity, decent speed, and cost-efficiency, hard disk drives are the most suitable option.
