What are Facebook cache files?
In computers and programming, a cache is a virtual location where data and information can be temporarily stored to speed up loading times. Facebook uses this to maintain temporary data from all the links and files users upload to the site.
How does Facebook cache work?
Facebook’s caches store photos and videos on NAND-flash based Solid State Drives (SSDs). We use SSDs because they provide much higher capacity than DRAM (i.e., can cache many more photos) and have much higher random read rates than traditional hard drives (i.e., can serve many more requests each second).
Does Facebook still use memcached?
Here at Facebook, we’re likely the world’s largest user of memcached. We use memcached to alleviate database load. memcached is already fast, but we need it to be faster and more efficient than most installations. We use more than 800 servers supplying over 28 terabytes of memory to our users.

How is the origin cache used in Facebook?
The origin cache is colocated with the storage backend to reduce accesses to the disk-based storage, and 1x was the cache size used in production at the time of the study. The clairvoyant algorithm relies on future information and is unattainable in practice, but provides an upper bound on achievable hit ratios.
When did Facebook start using blockcache in CDN?
Based on the results of our initial study, the Facebook CDN team worked to implement an initial solution in late 2014 — named BlockCache — which applies the Segmented LRU logic to large fixed-size blocks of items. In a nutshell, BlockCache restricts its writes to fixed-sized blocks that are aligned in the SSD’s logical address space.
