> By its own count, Wal-Mart has 460 terabytes of data stored on Teradata mainframes, made by NCR, at its Bentonville headquarters. To put that in perspective, the Internet has less than half as much data, according to experts.
~15 years later, 460TB are about 10.000 euros in cheap over-the-counter hard disks.
or 70k € in SSDs.
- ericpauley 8y agoI find this statistic dubious at best, given that by 2004 the internet had hundreds of millions of users. Even if we're generous and assume they mean public data on the internet, that'd be less than 1MB of data per person.
- mattnewton 8y agoHow many people were passive consumers then though? Also, hough much lighter weight was the content? This is before smartphone videos were being uploaded after all, 2004 was still an era where you might have a page on your personal site for your dog and everything was static html + css.
- autokad 8y agoI guess its subjective by what they mean by "the Internet has less than half as much data". I imagine what existed on file sharing sites was more (if that counts). As of 2007, I had 1 TB of specific types of content, which would have been a tiny tiny fraction of what was on sites like morpheus/kazaa at the time in 2004.
- totallyashill 8y agoThat 460TB of data has grown exponentially with the data brought in from stores, and from our growing e-com side over in Sunnyvale. If I had to place a number, it's well over the ExB barrier.
- froindt 8y agoAs a very rough ballpark, hard drive cost was around $1/GB, putting a single copy of everything around a half million dollars. Honestly quite a bit less then I expected for back then. Of course there are tons of other costs, but still not unreasonable for a Walmart size company. http://www.mkomo.com/cost-per-gigabyte http://www.mkomo.com/cost-per-gigabyte
