The problem is simple• While the storage capacities of hard drives have increased massively over the years, access speeds—the rate at which data can be read from drives have not kept up.• One typical drive from 1990 could store 1,370 MB of data and had a transfer speed of 4.4 MB/s
• so you could read all the data from a full drive in around five minutes.• Over 20 years later, one terabyte drives are the norm, but the transfer speed is around 100 MB/s, so it takes more than two and a half hours to read all the data off the disk.
