Google Uses Faster Storage For High Demand Pages

Google uses faster storage for high demand pages: -

Google indexes content on different types of storage based on how likely they are to be searched.

Google reveals that the search index uses a tiered system in which the most popular content is indexed onto faster, more expensive storage.

Google builds its search index, the content is indexed on three types of storage:

RAM (Random Access Memory): the fastest and the most expensive.

SSD (Solid State Drive): very fast but prohibitively expensive.

HDD (hard drive): the slowest and cheapest.

Google reserves the fastest storage for documents that may appear frequently in search results.

Content accessed every second will eventually be stored in RAM or SSD, which is a small amount of Google's entire index.

Most of the Google index is stored on hard drives because hard drives are cheap, accessible, and easy to replace.

The first time Google has given information to the public about its search index storage levels.

It is interesting to know that the most wanted content is stored on RAM and SSD.

The cost of storing even a percentage of Google's index on RAM and SSDs must be outrageous.

Although the cost of faster storage is likely to be justified by the importance of the documents inside to people.

The demand for content must be so high that Google does not want to risk delaying its distribution to Internet users.

When it comes to SEO, there is no way to optimize for one type of storage over the other and there is no way to know what level of storage the site is indexed to.

A decidedly small percentage of web pages are indexed to RAM or SSD.

Bringing it back to SEO is a good thing because it means the majority of sites compete on an equal footing when it comes to index storage speed.
