Seagate's Barracuda SSD bares its teeth at PC, laptop upgraders

SATA flash drives to put low-cap disk on endangered list

Seagate has fired a new Barracuda SSD at the home server, PC and notebook disk replacement markets.

It's a 6Gbit/s SATA SSD in a 2.5-inch form factor, with capacities ranging from 250GB, through 500GB and 1TB, up to 2TB. The performance claims up to 90,000 random read IOPS, 540MB/sec sequential read and 520MB/sec sequential write. Seagate has not revealed random write IOPS.

These are on a par with Seagate's Nytro 141 SSD, introduced a year ago, with the same 6gig SATA interface, TLC (3bits/cell) 3D NAND and capacities up to 1TB.

We might assume Seagate's supplier has bumped up the 3D NAND layer count to double the capacity.

The Nytro 141 did up to 92,000/88,000 random read/write IOPS, which seems respectable enough and not much skewed in favour of reads over writes. We wouldn't expect the Barracuda SSD to be much different.


The drive can sustain up to 1,092TB written over its life and has a 5-year warranty. That equates to, we calculate, 0.6 drive writes per day (using 4 x 365 and 1 x 366 days/year) at the 2TB capacity level.

It has 1.8-million-hour mean time between failures, a useful increase on the Nytro 141's 1.5 million hours, and an ultra-low power mode.

Seagate's Barracuda brand now includes both disk drives and SSDs, with the Barracuda Pro disk drive capacities ranging from 2TB to 12TB.

Prices start at $79.99 (£74.99) for 250GB, going up to $249.99 (£229.99) for the 1TB. We have no dollar tag for the 2TB model but its UK price is set at £449.99.

Seagate said it will become generally available in September.

    In-brief Governments around the world should pass intellectual property laws that grant rights to AI systems, two academics at the University of New South Wales in Australia argued.

    Alexandra George, and Toby Walsh, professors of law and AI, respectively, believe failing to recognize machines as inventors could have long-lasting impacts on economies and societies. 

    "If courts and governments decide that AI-made inventions cannot be patented, the implications could be huge," they wrote in a comment article published in Nature. "Funders and businesses would be less incentivized to pursue useful research using AI inventors when a return on their investment could be limited. Society could miss out on the development of worthwhile and life-saving inventions."

    More papers describing the orders and messages the US President can issue in the event of apocalyptic crises, such as a devastating nuclear attack, have been declassified and released for all to see.

    These government files are part of a larger collection of records that discuss the nature, reach, and use of secret Presidential Emergency Action Documents: these are executive orders, announcements, and statements to Congress that are all ready to sign and send out as soon as a doomsday scenario occurs. PEADs are supposed to give America's commander-in-chief immediate extraordinary powers to overcome extraordinary events.

    PEADs have never been declassified or revealed before. They remain hush-hush, and their exact details are not publicly known.

  • Stolen university credentials up for sale by Russian crooks, FBI warns
    Forget dark-web souks, thousands of these are already being traded on public bazaars

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.
