How it works
Divide the price by the capacity in gigabytes to get the cost of one gigabyte. Multiply that by 1000 for the cost of a terabyte, since a terabyte is 1000 gigabytes.
The lowest cost per gigabyte is not always the best buy. Speed, warranty and how you will use the drive matter too.
Worked example
A drive at $80.00 with 1,000 GB of space works out to $0.080 per gigabyte, or $80.00 per terabyte.
Questions
Does a bigger drive always cost less per GB?
Often, but not always. Prices change by model and by season, so compare the listings you are looking at.
Does speed change the value?
Yes. A faster drive can cost more per gigabyte and still be the right buy for some work.
Should I use the price with tax?
Use the price you will actually pay, including any tax or shipping, for an honest comparison.
