Let’s take a look at the news. Post was not sent - check your email addresses! Essentially, SMR comes in three variations – DMSMR, HMSMR and HASMR. In a typical small business/home NAS environment, workloads tend to be bursty in nature, leaving sufficient idle time for garbage collection and other maintenance operations. Jim Salter. iXsystems and Western Digital have been working to identify and resolve the ZFS compatibility issue with the WD Red DM-SMR drives. An elaborate investigation and discussion in a Smartmontools thread reveals that both Western Digital and Seagate appear to be shipping HDDs with "DM-SMR" (drive-managed SMR), a feature where the HDD's controller internally performs SMR to increase data density when the physical media is running out of space under CMR (conventional magnetic recording, with conventionally spaced tracks). All three of the surviving conventional hard drive vendors—Toshiba, Western Digital, and Seagate—have gotten caught sneaking disks featuring Shingled Magnetic Recording technology into unexpected places recently. Sign up or login to join the discussions! Depending on the system architecture, implementing these modifications may seem like an onerous task, yet once developers gain SMR familiarity and optimize their applications for sequential writing, they can take advantage of unsurpassed levels of reliability and quality.
