Seagate has officially introduced its fifth-generation solid-state hybrid drives (SSHDs) under the FireCuda brand name. They have a thinner form-factor compared to previous-gen solutions. The drives use Seagate’s 1 TB SMR platters as well as the company’s multi-tier cache technology. The FireCuda 2.5” are the first SSHDs to use shingled magnetic recording (SMR).

The Seagate FireCuda 2.5” family will offer 500 GB, 1 TB and 2 TB capacities and will be compatible with both desktops and thin laptops, thanks to its 7 mm z-height (down from 9.5 mm in case of the Laptop SSHD drives). To a large extent, the Seagate FireCuda SSHDs resemble the recently announced BarraCuda 2.5” HDDs: the drives are also based on the 1 TB SMR platters which have an areal density of more than 1.3 Tb/in2 (note that the areal density of the FireCuda products is higher compared to that of BarraCuda devices). They feature 5400 RPM spindle speed and come with 128 MB of DRAM cache buffer. The maximum transfer rate and average latency for the BarraCuda 2.5” and FireCuda 2.5” are the same: 140 MB/s and 5.6 ms.

The differentiating aspect of the FireCuda SSHDs is their 8 GB NAND buffer. It caches data from frequently used sectors to enable faster boot times and shorter load times for certain applications. Therefore, when it comes to real-world performance, FireCuda 2.5” SSHDs should provide better performance compared to the BarraCuda 2.5” HDDs. However, it is unknown how the FireCuda 2.5” drive stack up against the Laptop SSHDs based on PMR platters. Seagate has not revealed whether the new FireCuda SSHDs use a new caching algorithm compared to the previous-gen hybrid hard drives, but this is certainly a possibility given the use of SMR platters. As before, the company says that the algorithm is continuously trying to optimize performance of FireCuda SSHDs.

Seagate has started to ship the FireCuda drives to its customers, but has not listed official prices or market availability dates. The latter depends on retailers and/or PC makers. Seagate tells us that the FireCuda 2.5" 2 TB will cost around $100, but the supply/demand situation is bound to affect that pricing. Meanwhile, Amazon offers the FireCuda 2.5" 1 TB for $70. All of the previous-gen Laptop SSHDs ended up in retail, so, it is a question of time before the whole FireCuda 2.5" family will be up for grabs. One of the advantages of Seagate’s hybrid drives is their five-year warranty, which is longer than that of typical HDDs.

    Finally!, Geez, it seemed obvious to me that SMR + NAND was a great idea .. it sure took em long enough though!
  • extide - Friday, October 21, 2016 - link

    And, what a bunch of cheap asses, still only 8GB of NAND..?
  • ddriver - Friday, October 21, 2016 - link

    So they put a lousy ssd inside a lousy hdd and came up with a lousy name for it... I am sure it will be great LOL
  • edlee - Friday, October 21, 2016 - link

    i fully agree, 8gb of nand is pathetic, at least do 32Gb at the bare minimum
  • TheinsanegamerN - Friday, October 21, 2016 - link

    32GB nand and 7200RPM spin speed.

    This is a SMR drive. You can polish a turd but it's still a turd.
  • ddriver - Saturday, October 22, 2016 - link

    Yeah, but polish it well, put some glitter on it, a thick layer of varnish, put it in a shiny package and plenty of dummies will line up to buy it at a premium.

    I upgraded my PS4 with this 2tb SSHD (ST2000LX001) wroks really great!
  • edward1987 - Monday, December 5, 2016 - link

    I just did quick search and looks like none apart from span .com have this HDD in stock, must be popular choice :)

    8GB of Nand?
    Throw in 128GB and we will talk
