I have a synology 920+ NAS and want to buy two external USB HDD's for backup. Western Digital (WD), a leading manufacturer of storage devices, offers two distinct technologies for HDDs: Conventional Magnetic Recording (CMR) and Shingled Magnetic Recording (SMR). To manage the complexities of the shingled write process, SMR drives require specialized firmware called a “media cache” which queues up writes in cache before committing sequentially to the disk. But it is not recommended to use SMR drives for applications with significant load (for example in NAS boxes or for 24x7 use). 4 Tbpsi so we sized the 36TB drive as 1. These technologies represent different approaches to storing data on hard drives, a crucial component of modern computing infrastructure. WD西部数据 .
