The next profile looks at a file server, with 80% read and 20% write workload spread out over multiple transfer sizes ranging from 512-byte to 64KB.

Along with the change in nomenclature, Seagate implemented several platform changes to the SSHD Gen3 as well. While Gen2 provided users with 8GB SLC NAND, the Gen3 switched to 8GB MLC NAND. This modification does sacrifice some endurance, but the majority of users won’t deplete the endurance for the lifetime of the drive’s warranty making it mostly a non-issue. By switching to MLC NAND, Seagate is also able to reduce the Gen3 production cost greatly and thus lower the price significantly. Seagate has also decided to streamline their laptop drive production by exclusively offering 5,400 RPM drives. So while the Gen2 had a 7,200 RPM drive, the Gen3 spins at 5,400 RPM. Thanks to improvements in the cache technology, the cache miss pain of hitting the slower spinning drive should be mitigated, but regardless, hitting the drive without flash assistance is going to hurt a little more than in the Gen2 drive.

Host Aware, HA-SMR, which is designed to give ZFS insight into the SMR process. Note that ZFS code to use HA-SMR does not appear to exist. Without that code, a HA-SMR drive behaves like a DM-SMR drive where ZFS is concerned.

Ironically, the barebones 5TB drive is up to 50% more expensive than the external model, despite having fewer materials (no cable, chassis or electronics); the laws of supply and demand at work.Voer SeagateFirmwareUpdate_SeaFlash_Dell_Kahuna_UUU_FDL_KernelV4.7_New_Config_09-28-2016_13-54-18.exe uit als beheerder.
