WD My Passport: 5TB of shingled disk capacity in my shirt pocket – Blocks and Files

Shingling


The 5TB drive, claimed to be the thinnest such drive available, uses drive-managed shingling. This slows the data rewrite process as blocks of tracks have to be read, the data altered, and then the block re-written to the drive. Fresh data writes to empty tracks proceed as normal. 

Large sequential files are accepted by the drive and written with no interruption. Smaller randomly-addressed files are stored temporarily in a cache and then, when the drive is idle, written out in a sequential manner, with address translation to speed the writing process.
