Toshiba leaps aboard flash-platter combo bandwagon with a wild cry

I didn't get a hybrid drive outta that guy!


Toshiba has produced its own hybrid drive, following Seagate's lead and WD's stated intention.

A hybrid disk drive adds a flash memory cache for hot data to the spinning platters to provide a combination of speeded-up IO and disk capacity that's not as fast as a solid state drive (SSD) but a lot cheaper. The drives look to be a good fit with ultrabooks and tablet computers where thin dimensions, low battery power draw and a good capacity level are needed. Seagate has been mining this seam with its 2.5-inch Momentus XT, now in its third generation

Toshiba demonstrated a 1TB hybrid drive in August and has now announced its MQ01ABD-H drive with 750GB and 1TB capacity points and a 6Gbit/s SATA interface. It is 9.5mm thick and spins at 5,400rpm and has an 8MB flash cache. A self-learning algorithm populates this with high-access rate data. That should result in faster startup, application and data file load times.

Seagate's Momentus XT also has 8GB of flash, maxes out at 750GB, 250MB less than the Toshiba drive, but spins at 7,200rpm. We expect a terabyte model and a 500GB single platter Momentus Thin XT pretty soon.

Toshiba says its new drive will appear in notebook PCS and be available in them before the end of the year.

That means that we have a clean sweep of disk drive manufacturers producing hybrid drives and we can expect the technology to spread further throughout each manufacturer's range. Who would not like a faster-responding disk drive? ®

    Enhanced 'Cyber and Critical Technology Partnership' will transport crime to harsh penal regime on the other side of the world

    The United Kingdom and Australia have signed a Cyber and Critical Technology Partnership that will, among other things, transport criminals to a harsh penal regime on the other side of the world.

    Australian foreign minister Marise Payne and UK foreign secretary Liz Truss yesterday inked the document in Sydney but haven't revealed the text of the pact.

    What we do know is that the two nations have pledged to "Increase deterrence by raising the costs for hostile state activity in cyberspace – including through strategic co-ordination of our cyber sanctions regimes." That's code for both nations adopting the same deterrents and punishments for online malfeasance so that malfeasants can't shop jurisdictions to find more lenient penalties.

  • Japan's Supreme Court rules cryptojacking scripts are not malware

    Coinhive-slinger wins on appeal

    A man found guilty of using the Coinhive cryptojacking script to mine Monero on users' PCs while they browsed the web has been cleared by Japan's Supreme Court on the grounds that crypto mining software is not malware.

    Tokyo High Court ruled against the defendant, 34-year-old Seiya Moroi, on charges of keeping electromagnetic records of an unjust program. That unjust program was Coinhive, a "cryptojacking" script that mines for Monero by pinching some CPU cycles when users visit a web page that includes the code. Moroi ran the code on his website.

    Coinhive has been blocked by malware and antivirus vendors as it slows down other processes, increases utility bills, and creates wear and tear on your device. But in many ways Coinhive's Javascript code acts no differently to advertisements.
