Enterprise Performance 15K HDD v5 Internals




The Enterprise Performance TurboBoost 15K HDD v5 comes in the 2.5" form factor with a 15nmm z-height.




The drive appears similar to normal 2.5" drives. A foam pad resides between the PCB and drive housing, and thermal pads cover the controllers.




The SMOOTH/Seagate co-branded controller handles motor operations. A co-branded LSI/Seagate TT50431 controller is flanked by a 128MB Samsung DRAM package. The LSI controller is new to this generation of SSHD; the previous model featured a Marvell processor. The LSI/Seagate controller is the same model used on the standard 15K v5, but also handles the AMT caching algorithms, and the NAND chip that resides near the 12Gb/s SAS connection. The 12Gb/s SAS connection provides wide compatibility with the latest RAID controllers and HBAs.




Idle power consumption is a pain point in the datacenter. The Seagate Enterprise Performance TurboBoost 15K HDD v5 utilizes PowerChoice Technology, Seagate's proprietary implementation of the T10/T13 Approved Standard. PowerChoice provides four enhanced idle modes that place the drive into deeper quasi-sleep cycles to conserve power; the length of drive inactivity triggers these idle modes. The feature is enabled with a SAS Mode Page or SATA Set Feature command.


There is also the option for immediate host-initiated power transitions in a typical implementation. Once enabled, PowerChoice places the drive into successively deeper idle states with SAS/SATA commands, but each consecutive sleep mode requires more time for resumption. We did not test with enhanced PowerChoice states enabled.


The standard Enterprise Performance 15K HDD v5 provides a 6.4-watt average power draw during the idle power state. The Enterprise Performance TurboBoost model matches the same idle power draw, albeit after a short period of settling.



Enterprise Performance 15K HDD v5 Specifications


The 12Gb/s Seagate Enterprise Performance TurboBoost 15K HDD we are testing today features the 512E format with the ST600MX0052 part number. There are 4KN, 512E, SED, and FIPS 140-2 variants available with varying part numbers.
