Lab subscriptions provide unlimited storage to all accounts that are members, so you don’t need both personal and Lab storage subscriptions.
When your account is added a Lab subscription, the timer on your personal account storage subscription is paused and you won’t be charged for renewal. Your personal storage quota and timer resumes if you ever leave the Lab.
