Consider this: the less drives you have, the less connections (SATA or USB3), storage space, and electricity you need, so you have less overall investment. Bigger drives are also probably easier to sell or repurpose in the future.
@CrazyMiner Green box with the balance, click "more info", should pop up window with info and "numeric account id" will be second thing listed. is that what you are looking for?
@CrazyMiner having no experience with those errors i would check two things, there is a send transaction to establish a public key for the account and that the filenames on the plot files start with the numeric id for the account. check the account on the blockchain explorer for the transactions and it will provide the numeric id (if there is any transactions for the account). i hope this helps.
