Seagate BarraCuda 5 TB Internal Hard Drive HDD – 2.5 Inch SATA 6 Gb/s 5400 RPM 128 MB Cache for Computer Desktop PC (ST5000LM000)

Product Information

The Seagate SSHD Gen3 power consumption is lower than the Gen2 in every test but idle, where it is nearly the same. Across the board, the Gen3 made strong gains and saved 0.3-1.2 watts depending on the job it was doing. The first is our database profile, with a 67% read and 33% write workload mix primarily centered on 8K transfer sizes.

Our Database profile again showed the Seagate Gen3 as a strong runner-up to the Gen2 plateauing at 64 IOPS, steady to 128. Seagate datasheet for 8TB Archive v2 showing HA-SMR: https://www.seagate.com/www-content...seagate-archive-hdd/en-us/docs/100795782a.pdf While the vast majority of the Seagate BarraCuda 2.5" 4 TB HDDs will use a four-platter configuration, some Seagate customers have apparently requested a five-platter configuration. Obviously, being based on 800 GB platters, such drives have lower areal density and, perhaps, different performance and behavior.With any laptop drive, power consumption is an important factor for users. The key sources of power draw get narrowed down to either the bright screen or the storage device used. In the next test, we record the average power consumed over a small range of synthetic benchmarks. For reference, Seagate lists an average idle power rate of 0.9 watts and an active seek rate of 2.5 watts. Ubiquiti UniFi Cloud Key Gen2 Plus Hard Drive Upgrade & Failures has caused me a number of headaches over the last year or so. Read on to hear the issues I’ve experience and how I’ve overcome them. The portable bus-powered external hard drive market is served by all three HDD vendors - Seagate, Western Digital, and Toshiba. Seagate has been making use of SMR in the recent past for this segment. Western Digital is known for being coy about divulging the technology used inside its consumer products. It turns out that WD has also been using SMR technology since last 2016 in its external hard drives. In response to our specific query, WD officially confirmed the use of SMR platters in the hard drive inside the WD My Passport 5TB 2019 edition. Rounding out the figures, in our Workstation profile, the Gen3 placed a solid second, again to the Gen2. The Gen3 plateaued at 64 IOPS and had a minor decrease at 128 IOPS.

The table below presents the detailed specifications and miscellaneous aspects of the 2019 WD My Passport 5TB and how they compare against similar external drives currently in the market. n) HiSMRFs research file system for SMR: 2014, https://www.researchgate.net/public...rmance_file_system_for_shingled_storage_array Drive Managed, DM-SMR, which is opaque to the OS. This means ZFS cannot "target" writes, and is the worst type for ZFS use. As a rule of thumb, avoid DM-SMR drives, unless you have a specific use case where the increased resilver time (a week or longer) is acceptable, and you know the drive will function for ZFS during resilver.

New technology such as HAMR (Heat Assisted Magnetic Recording, Seagate) or MAMR (Microwave Assisted Magnetic Recording, WD) can be used with or without shingling. The first drives are expected in 2020, in either flavor.Experience — For more than 20 years, Seagate has manufactured and delivered the super-reliable BarraCuda family of drives
