Seagate Barracuda ST3000DM001 Hard Drive Review
Manufacturer: Seagate Technology LLC
Full Disclosure: The product sample used in this article has been provided by Seagate.
Back on March 2011, Seagate debuted their original Barracuda XT 3TB hard drive, model ST33000651AS, which used five platters to supply 3000 gigabytes of capacity over a SATA 6Gb/s interface. Seven short months later, they've returned to introduce a replacement: the Seagate Barracuda 3TB hard drive ST3000DM001, which features the same 6 GB/s interface and 64MB cache buffer but now utilizes only three 1GB density platters. Seagate has also introduced a number of refined technologies to help improve overall hard drive performance, including: dual core 40nm processor technology, DDR2 DRAM buffer, and refined caching algorithms. By reducing disc platters from five to three, it prolongs servo motor life and reduces heat output. Benchmark Reviews compared these two hard drives, to see exactly what's been gained.
Back on 21 September 2009, Seagate Technology was the first manufacturer to offer a SATA 6Gb/s (aka SATA-III) hard drive product with the industry's largest 64MB cache buffer. At its time, the 2TB Seagate Barracuda XT ST32000641AS was an impressive leap for high-density mechanical storage devices; primarily because it offered tremendous capacity along side commendable performance levels. Launching just over a year later, the 3TB version offers all of the same benefits of that made the series popular, but improves transfer speed performance while including free software to take Seagate drives beyond the 2TB limitation. Early adopters of the SATA 6Gb/s interface will appreciate the high-bandwidth transfer speeds that all high-capacity Seagate Barracuda-series storage solutions provide. Seagate has pleased enthusiasts and gamers with a 64MB cache buffer; the largest DRAM buffer on any commercial hard drive on the consumer market. Now Seagate takes one step further, and while both versions of the 3TB drive share similarities, there have also been a few industry changes since the 3TB Barracuda XT was originally unveiled.
The Seagate Barracuda series is designed for performance computer enthusiasts, as well as large-capacity storage systems. Manufacturer-supplied free enthusiast tools such as Seagate SeaTools software allows users to custom-define firmware parameters to enable performance features such as 'Short Stroke' and noise reduction. Featuring the industry's largest 3TB capacity and third-generation SATA 6Gb/s controller interface, the Seagate Barracuda is the first hard drive to also utilize 1TB storage disc platters. In this article, Benchmark Reviews tests the 3TB Seagate Barracuda ST3000DM001 hard drive against the drive it replaces: Seagate Barracuda XT model ST33000651AS.
What's new with Barracuda?
Barracuda is the industry's first hard drive to deliver 1TB per disk of capacity. The drive packs 340,000 tracks into every linear inch measured across the radius of the disc. This means that average track sizes have decreased to a mere 75 nanometers - smaller even than a flu virus. Seagate has enabled these very small densities and improved tracking over previous generations of Barracuda by deploying new nano actuation technology on each read/write arm assembly.
Seagate has also introduced a number of refined technologies to help improve overall performance, including dual core, 40nm processor technology, DDR2 DRAM and refined caching algorithms.
With the introduction of the new Barracuda, Seagate will be phasing out the 5900RPM Barracuda Green product line. This decision reflects the fact that low-power, or reduced-RPM, hard drives in the desktop market do not save enough electricity to justify the performance penalty. Seagate's analysis demonstrates that a reduced RPM hard drive saves only 20 to 40 cents per year in electricity cost at a cost of 20% to 40% in reduced performance. The 7200RPM Barracuda hard drives enable higher user productivity, delivering more value.
