Seagate BarraCuda Pro 14TB HDD Review: Massive Storage for Desktops

The exponential increase in data storage requirements over the last decade or so has been handled by regular increases in hard drive capacities. Multiple HDD vendors supply them to cloud providers (who get the main benefits from advancements in hard drive technologies), but, Seagate is the only one to also focus on the home consumer / prosumer market. In the last three generations, we have seen that Seagate has been the first to target the desktop storage market with their highest capacity drives. The 10 TB BarraCuda Pro was released in Q3 2016, and the 12 TB version in Q4 2017. Seagate is launching the 14 TB version today.

The Seagate BarraCuda Pro 14TB is a 7200RPM SATAIII (6 Gbps) hard drive with a 256MB multi-segmented DRAM cache. It features eight PMR platters with a 1077 Gb/in2 areal density in a sealed enclosure filled with helium. The main change compared to the 12TB version introduced last year is the usage of two-dimensional magnetic recording (TDMR) heads, allowing for higher areal density (1077 Gb/in2 vs. 923 Gb/in2 without TDMR).

Launch price is $580.

Toshiba has also announced new 12 and 14 TB hard drives, aimed at businesses:

Toshiba is announcing that it has started sampling of its latest MG07SCA-series enterprise-class helium-filled hard drives. Notable for utilizing a dual-port SAS interface, the HDDs are aimed at business-critical servers and are rated for 550 TB per year workloads.

Toshiba's MG07SCA lineup of enterprise-grade hard drive includes two SKUs at 12 TB and 14 TB respectively. The flagship 14 TB model relies on nine PMR platters from Showa Denko with ~1.56 TB capacity each, whereas the 12 TB model relies on eight platters. Both HDDs feature a 7200 RPM spindle speed, a 256 MB cache buffer, and a dual-port SAS 12 Gbps interface. Just like their SATA brethren, the new SAS hard drives are based on Toshiba's latest-gen helium-filled platform for business-critical HDDs with all the possible enhancements to improve reliability and durability, including top and bottom attached motors, RVFF, environmental sensors, and so on.

    An estimate of what it would take to add all stars from the final Gaia [wikipedia.org] catalog to Space Engine: 34 bytes per star for 1,142,679,769 stars, representing 0.5% of the Milky Way galaxy. That's 36.2 GiB (about 38.85 GB). If the database ID index was doubled to 64 bits, that would be 38 bytes per star, and adding another 2 bytes for the spectral class gets you to 40 bytes.

    200 billion is a lower estimate for the number of stars in the Milky Way. A future mission may track every star in the galaxy. 400 billion @ 40 bytes each would be 16 terabytes. Which busts through this measly 14 TB drive.

    The actual data that will be collected by the Gaia mission is closer to 200 TB uncompressed. Again, that's for a fraction of our galaxy's stars, although they also find some asteroids, large exoplanets, extragalactic stars, etc.

    Space Engine offers Solar System HD [spaceengine.org] and Solar System Ultra [spaceengine.org] add-ons that add higher resolution imagery of the terrestrial planets, Ceres, Vesta, Pluto, Triton, etc. These total over 10 GB per object for Venus and Earth. And it's just a starting point. There will be more missions to more solar system objects. And if you consider something like Earth, there's petabytes [gearthblog.com] of imagery of the surface (even more if you count Street View [gmapswidget.com]).

    Finally, you have hundreds of billions of galaxies in the universe, and we're starting to locate individual stars and other objects in other galaxies. And of course, we know about thousands of exoplanets, but there are likely trillions. We may locate a lot more of these objects later in the century, if we can launch many cheap and big telescopes, gravitational lensing telescopes, etc.

    In conclusion, if you want to explore the universe using data not stored on some remote server, you'll eventually want more than 14-16 terabytes of local storage (a lot of RAM would be nice too). SSD manufacturers are going to be the first to reach crazy milestones like 100 TB and 1 PB in a single 3.5" or 2.5" drive. If they can also narrow or eliminate the $/TB gap, then HDDs will be dead.
