Transcript

As I mentioned earlier, most hard drives come with a built-in memory cache, usually a few megabytes of high-speed RAM. Data recently written to disk is stored there along with the recently read data. When a disk caches data like this, it has the effect of performing above its physical limits of reading and writing to disk. Azure VMs have a feature called BlobCache, a combination of the machine's RAM and local SSD, the D drive on a Windows VM, to provide high-speed read caching for database operations. A BlobCache could be likened to a hard disk cache on steroids. This feature is only available on high-scale virtual machines in combination with premium SSDs.
