Please note a True Account is still a Free Service Account. The Free Service is designed for personal and casual use only. If you use it for business purposes or if you use it very heavily, you should upgrade to a paid account.
There are quite a lot of restrictions to free services. Generally speaking, free service is good if you backup or share digital photos. 1GB storage is good for about 500-1000 high-resolution digital photos. If you share very large video files, big software application installer files, or if you want to backup your whole PC, the free service is not enough.
For a paid service, if you order N GB storage, you get 4 x N GB of monthly download bytes. Please note your monthly download bytes resets on the day-of-month when you signed up DriveHQ.com (not the day-of-month when you ordered the paid service, or 1st of each month)
