In the 1980s, the average capacity of a hard drive for a personal computer was 5MB (if the computer even had a hard drive at all). Today, it is possible to purchase drives with a capacity of up to 8TB of data. Although this may seem like a very large amount, it is actually quite small when compared to the estimated volume of new data produced daily, which reaches 2.5 EB — about 2.5 million TB. text/html 2026-01-23T13:02:38+00:00 Anonymous (anonymous@undisclosed.example.com) https://bigdatakms.pl/doku.php?id=en:przyklady&rev=1769173358&do=diff Example For testing purposes, the Yelp Dataset was downloaded, containing 6,990,280 reviews, 150,346 businesses, 11 metropolitan areas, and 200,100 photos.
