Why is the actual storage capacity of the product slightly less than the volume specified on the product's package?

Category : Specification / Capacity / Performance

All storage products will display a less memory capacity on a computer than stated. The discrepancy results from the different ways flash memory and hard drive manufacturers calculate megabyte. Hard drive manufacturers calculate a megabyte (or 1,000x1,000 bytes) as 1,000KBs, whereas the binary calculation is 1,024KBs. So, for a 4GB storage device, Windows will calculate it as having a capacity of 3.72GB (4,000,000,000÷1,024÷1,024÷1,024=3.72GB).


In addition, Transcend will save partial memory capacity for firmware, software applications, data storage and maintenance.
