Question

How many bytes memory space are there in an 80 gb hard disk? (B in GB for byte)

Answer 1

Answer:

• Hard drive makers however assume that 80GB means 80,000,000,000 bytes, since they use the definition of 1GB = 1,000,000,000 bytes.
• SSD vendors thus use the same definition. Now 80,000,000,000 bytes actually equals 74.5GB, so that's all the space you get to use on the drive.
