Security researchers from the University of Michigan and Zhejiang University in China have published a paper on an acoustic attack vector that could crash a mechanical hard drive, leading to damage for both the hardware and software. The attack does not require fancy equipment, either—an attacker could use regular, built-in speakers or nearby emitters to cause persistent errors on the target system. "Our experiments show that audible sound causes the head stack assembly to vibrate outside of operational bounds; ultrasonic sound causes false positives in the shock sensor, which is designed...

Western Digital (WD) has pulled the wraps off a new high capacity storage drive that is aimed directly at cloud and enterprise data centers. The new Ultrastar DC HC530 has 14TB of storage capacity, which WD says is the highest capacity conventional magnetic recording hard drive on the market today. The HC530 uses fifth-generation HelioSeal technology and is meant to be perfect for environments where storage density, watt/TB and $/TB are critical. The drive will allow enterprise users to build petabyte-scale infrastructures. WD says that the new HC530 is a follow-on to the 14TB shielded magnetic... Read more...
With solid state drives (SSDs) having long ago taken the speed crown away from hard disk drives (HDDs), manufacturers of the latter storage device have primarily resorted to pushing the boundaries with regards to capacity. In recent months, we've seen HDDs reach capacities of 14TB, but that doesn't mean that there won't be advances that help increase performance along the way. That's where Seagate comes into focus with what it is calling Multi Actuator technology. Seagate explains that while today's HDDs have greater areal densities than ever before, it has handicapped overall drive performance.... Read more...
Back in September we heard rumors floating around that "very soon" Toshiba would be launching a massive 14TB storage solution for desktop computers. Fast-forward three months and the new Toshiba MG07ACA series HDD has landed and is heralded as the world's first 9-disk helium-sealed design. The drive brings 14TB of conventional magnetic recording (CMR) storage capacity and spins at 7,200 rpm. Since the drive uses an industry standard 3.5-inch form factor, it will easily integrate into existing cloud-scale storage infrastructures, servers, and storage arrays. This might be the ideal HDD for computer... Read more...
In case you have noticed, our data storage needs are growing at an exponential rate. Data centers have an increasing need to store huge amounts of information to power our digital world. Although there is an increasing shift towards solid state drive (SSDs) for their blazing fast performance and low-power profile, hard disk drive (HDDs) still carry the brunt of the load when it comes to storage currently and in the immediate future. According to Western Digital, roughly 70 percent of the thousands of exabytes of data globally will reside on HDDs, versus 30 percent for flash. When focusing solely... Read more...
Seagate has rolled out a pair of new HDDs with the first of them being a 12TB 3.5-inch unit in the IronWolf line aimed specifically at NAS environments. That drive has features specifically to make it perform inside a network attached storage (NAS) device including AgileArray and dual-plane balancing along with RAID optimizations built right in. Seagate also promises that the IronWolf drive has advanced power management integrated. IronWolf drives are offered in a range of capacities with the largest being the new 12TB drive. The drive was built to support a work rate of 180TB per year... Read more...
The need for more bulk storage isn't slowing down, and in fact continues to grow at an incredible rate. At one point, a 4TB hard drive seemed like it offered a ton of digital breathing room. Today, that's not so much the case. As we capture our photos and videos at higher resolutions (8K is right around the corner), many users will reach a point where they feel they simply can't have enough storage. And that's to say nothing of the insatiable appetite for storage in the enterprise and data center.  Earlier this year, HGST blew our minds when it began shipping its first 12TB hard drive, the...

Toshiba is apparently getting ready to release a 14-terabyte capacity hard drive model. So say company representatives at the Huawei Connect conference in Shanghai, China, who indicated that 14TB helium-filled HDDs would hit the marketplace "very soon." When pressed for clarification on how soon they were talking about, the representatives said the large capacity HDDs would arrive by the end of 2017.The largest capacity HDD currently available is 12TB—both Seagate and Western Digital's HGST division offer 12TB models aimed at the enterprise market. These are single drive solutions and they are... Read more...
When it comes to the global computer storage market, it appears that Toshiba is demonstrating strong gains in a sector that is dominated by the likes of bellwethers like Seagate and Western Digital, which appeared previously to be the last standing competitors in an arena with heavy consolidation. However, not only was Toshiba the fastest growing vendor for hard disk drive (HDDs), but it also showed stronger gains than its larger competitors in the solid-state drive (SSD) sector during 2016. Toshiba showed a 9-percentage point growth during Q4 2016 in the HDD sector, and increased its revenue... Read more...
There’s no question that solid-state drives (SSDs) are all the rage today in consumer and enterprise computing. It’s hard to argue with the speed, small form-factors and energy efficiency of SSDs; but when it comes to price-per-gigabyte (especially in large capacities drives), hard disk drives (HDDs) still reign supreme. Seagate is looking to widen that pricing gap within the next few years by ramping up the capacity of its HDDs. While Seagate’s current HDDs top out at 10TB (12TB drives are currently sampling), CEO Stephen Luczo stated during his company’s most recent earnings call that 14TB and... Read more...
You might think that storage makers are 100 percent focused on solid state drives these days, but that isn't the case. Mechanical hard disk drives (HDDs) still offer the best price-per-gigabyte ratio for bulk storage duties, and to keep things going, Seagate today announced its Enterprise Performance 15K HDD v6 in 300GB, 600GB, and 900GB capacity options. This is the 6th generation of Seagate's Enterprise Performance HDD line and not only is it the fastest and best performing to date, Seagate claims you can't buy a faster HDD from any manufacturer. That translates into a sustained transfer rate... Read more...
We’ve seen some rather nasty ransomware making the rounds over the past few months, but a new strain is wreaking havoc on computers around the globe. Brazilian firm Morphus Labs first discovered the Windows-based ransomware, which has been given the name Mamba. So far, Mamba has been found on computers located in Brazil, India and even the United States. According to Morphus Labs researcher Renato Marinho, Mamba has been spreading as a result of people being tricked into interacting with phishing emails. Once a user has been “hooked”, Mamba gets down to business by infecting the host machine, and... Read more...
The lengths that researchers will go to in order to expose security weaknesses in computing technology never ceases to amaze us. The latest technological breakthrough (or security nightmare, depending on how you view it) comes to us courtesy of researchers from Cornell University, and it looks like something that could have been grabbed straight out of a James Bond flick. The researchers have targeted air-gapped computers, or computers that are completely cut off from unsecure networks (like the internet). As the researchers point out, “This measure is taken in order to prevent the leakage of sensitive... Read more...
Back in April, Seagate began shipping a new helium-filled 10TB hard drive for the enterprise market. The 3.5-inch form-factor HDD is available in 6Gb/s SATA and 12Gb/s SAS versions and comes backed by a 5-year warranty. Seagate is now ready to start spreading the helium love with three new product families that are available in capacities up to 10TB. The first of these drives, and the one likely to be most relevant to our readers is the 7200rpm BarraCuda Pro. This is the first HDD to use the BarraCuda moniker (albeit this time with a capitalized “C”) since the name was originally retired in 2013.... Read more...
