These days a large portion of it is just basically logs. Logs of all the traffic we're generating looking at content on the internet, to be used to try to target ads. That and videos, youtube itself probably accounts for a significant amount of that storage use.
- owl57 7y agoAre the logs of this scale and less-popular videos usually stored on SSD? I thought HDDs are still cheaper and RAID gives enough throughput given enough disks?
- dodobirdlord 7y agoLogs are probably on HDD, video might be on SSD given how aggressively it gets edge-cached.
- londons_explore 7y agoHDD's access time (10milliseconds or more), means a hard disk can't really serve more than 100 concurrent users, assuming each wants to stream a chunk of video every second. That makes it a poor choice for serving anything but the rarest of YouTube videos.
- owl57 7y agoI believe a typical video, stored in all of the Youtube formats, uses on the order of a megabyte per second. So, a 10TB disk probably holds about 100 days of video. Seems fine for videos that are watched less than once a day, that's probably a vast majority of Youtube's storage.
