Lucas123 writes: Seagate has finally adopted helium as an inert gas in its data center drives and has used it to produce a 10TB HDD for cloud-based data centers. Seagate had relied on its shingled magnetic recording technology for high-capacity drives right up until its last 8TB HDD, even after WD has used helium in several iterations of its hermetically sealed, 3.5-in HDDs. The lighter-than-air helium reduces friction on platters and allows more to be used. In Seagate's new HDD, it crammed seven platters 14 heads, a 25% increase in disk density over its 8TB drive.

An anonymous reader writes: In light of recent revelations from Kaspersky Labs about the Equation Group and persistent hard drive malware, I was curious about how easy it might be to verify my own system's drives to see if they were infected. I have no real reason to think they would be, but I was dismayed by the total lack of tools to independently verify such a thing. For instance, Seagate's firmware download pages provide files with no external hash, something Linux distributions do for all of their packages. Neither do they seem to provide a utility to read off the current firmware from a drive and verify its integrity.

Are there any utilities to do such a thing? Why don't these companies provide verification software to users? Has anyone compiled and posted a public list of known-good firmware hashes for the major hard drive vendors and models? This seems to be a critical hole in PC security. I did contact Seagate support asking for hashes of their latest firmware; I got a response stating, "...If you download the firmware directly from our website there is no risk on the file be tampered with." (Their phrasing, not mine.) Methinks somebody hasn't been keeping up with world events lately.

MrSeb was one of several readers to submit news that drive manufacturer Seagate has announced (and demoed) the first hard drive to squeeze a terabit into each square inch of platter. "'Initially this will result in 6TB 3.5-inch desktop drives and 2TB 2.5-inch laptop drives, but eventually Seagate is promising up to 60TB and 20TB respectively. To achieve such a huge leap in density, Seagate had to use a technology called heat-assisted magnetic recording (HAMR). Basically, the main issue that governs hard drive density is the size of each magnetic 'bit.' These can only be made so small until the magnetism of nearby bits affects them. With HAMR, 'high density' magnetic compounds that can withstand further miniaturization are used. The only problem is that these materials, such as iron platinum alloy, are more stubborn when it comes to writing data — but if you heat it first, that problem goes away. With HAMR, Seagate has strapped a laser to the hard drive head; when it wants to write data, the laser turns on. Reading data is still done conventionally, without the laser. In theory, HAMR should allow for areal densities up to 10 terabits per square inch (magnetic sites that are just 1nm long!), and thus desktop hard drives in the 60TB range."

AnInkle writes "Two months after acknowledging that their flagship 1.5TB Barracuda 7200.11s could hang while streaming video or during low-speed file transfers, Seagate again faces a swell of complaints about more drives failing just months after purchase. Again, The Tech Report pursued the matter until they received a response acknowledging the bricking issue. Seagate says they've isolated a 'potential firmware issue.' They say there's 'no data loss associated with this issue, and the data still resides on the drive;' however, 'the data on the hard drives may become inaccessible to the user when the host system is powered on.' If users don't like the idea of an expensive data-laden paperweight, Seagate is offering a firmware upgrade to address the matter, as well as data recovery services if needed. By offering free data recovery, Seagate seems to be trying to head off what could become a PR nightmare that may affect several models under both the Seagate and Maxtor brands."

Dave Robertson asks: "Fibre channel storage has been filtering down from the rarefied heights of big business and is now beginning to be a sensible option for smaller enterprises and institutions. An illuminating example of this is Apple's Xserve Raid which has set a new low price point for this type of storage - with some compromises, naturally. Fibre channel switches and host bus adapters have also fallen in price but generally, storage arrays such as those from Infortrend or EMC are still aimed at the medium to high-end enterprise market and are priced accordingly. These units are expensive in part because they aim to have very high availability and are therefore well-engineered and provide dual redundant everything." This brings us to the question: Is it possible to build your own Fibre Channnel storage array? "In some alternative markets - education for example - I see a need for server storage systems with very high transaction rates (I/Os per second) and the flexibility of FC, but without the need for very high availability and without the ability to pay enterprise prices. The Xserve Raid comes close to meeting the need but its major design compromise is to use ATA drives, thus losing the high I/O rate of FC drives.

I'm considering building my own experimental fibre channel storage unit. Disks are available from Seagate, and SCA to FC T-card adapters are also available. A hardware raid controller would also be nice.

Before launching into the project, I'd like to cast the net out and solicit the experiences and advice of anyone who has tried this. It should be relatively easy to create a single-drive unit similar to the Apcon TestDrive or a JBOD, but a RAID array may be more difficult. The design goals are to achieve a high I/O rate (we'll use postmark to measure this) in a fibre channel environment at the lowest possible price. We're prepared to compromise on availability and 'enterprise management features'. We'd like to use off the shelf components as far as possible.

Seagate has a good fibre channel primer, if you need to refresh your memory."

Keefe writes "Recently, Hitachi and Seagate have come out with two of the biggest desktop hard drives available on the market at a massive 400GB each. These two drives carry almost identical specifications, with the exception of the Seagate Barracuda and its Native Command Queuing technology. Read the review at Techware Labs to see how these two drives compare head to head, with and without NCQ enabled, and in a RAID configuration."

deweller writes "According to a story at MacCentral, Hard drive maker Seagate Technology LLC is seeking a court injunction to prevent a former employee, Pete Goglia, from going to work for Western Digital Corp. any time in the next 2 years, saying Goglia knows too much about Seagate's hard-drive reading and writing technology to work for a competitor."

swordboy writes "Seagate have just announced that they are going to standardize on a five year warranty for all of their hard drives, including desktop and notebook units. While this seems like amazing news, I'm certainly hoping that the company will be around to honor these warranties." The press release notes: "The new warranty applies retroactively to applicable hard drives shipped since June 1, 2004."

dncsky1530 writes "Seagate's recently filed a patent infringement lawsuit in the U.S. District Court for the District of Delaware against Cornice of Longmont, Colo. Now it is seeking an order from the U.S. International Trade Commission to exclude Cornice disk drives and any systems or products using or containing Cornice disc drives from entry into the United States. Seagate asserts that Cornice is infringing on seven of its U.S. patents that relate to several areas of disk drive technology."

stm2 writes "Thanks to an agreement between Lindows and Seagate, from October you will be able to choose a hard drive with or without Lindows. Michael Robertson, in his usual marketing speak, compares this to adding "Fluoride in the water", because now you get for free something you used to need to go after (people used to go to dentist to get their Fluoride). According to the PR, the OS can autodetect and configure itself on the host machine."

rchatterjee writes "SCSI is very close to joining ATA in leaving a parallel interface design behind in favor of serial one. Serial attached SCSI, as the standard will be known, is expected to be ratified sometime in the second quarter of this year according to this article at Computerworld. Hard drive manufacturers Seagate and Maxtor have already said that they will have drives conforming to the new standard shipping by the end of the year. The new standard will shatter the current SCSI throughput limit of 320 megabit/sec with a starting maximum throughput of 3 gigabit/sec. But before this thread turns into a SCSI fanboy vs. ATA fanboy flame war this other article states that Serial Attached SCSI will be compatible with SATA drives so you can have the best of both worlds."

Longinus writes "Yahoo! News is reporting that hard drive manufacturer Seagate has "overcome a significant challenge in magnetic memory with a new technology capable of achieving far beyond today's storage densities -- up to as great as 50 terabits per square inch. Currently, the highest storage densities hover around 50 gigabits per square inch, but Seagate said its heat-assisted magnetic recording (HAMR) technology could break through the so-called superparamagnetic limit -- a memory boundary based on data bits so small they become magnetically unstable." Perhaps the near future of storage technology lies, for now, not in nanotech or holography, but still in magnetic recording."

bjschrock writes "Tech-Junkie reports that Asus is rolling out new motherboards with the new Serial ATA interface, along with AGP 8X support. Serial ATA will soon become pretty popular with the release of new hardware like the Seagate Baracudda ATA V hard drive, that sports a 8MB cache. The main advantage of Serial ATA, besides a slight speed increase, is the much smaller cable and the ability to hot-swap."

Charlie Engasser wrote in to tell us about 216 gigabytes hard drives over at Seagate. Uses "Optically Assisted Winchester" (OAW), which "augments traditional magnetic read/write techniques with a laser to allow positioning so precise that it can store over 100,000 tracks across one inch of drive surface". I guess it just means in a few years we'll be able to do with video what we do today with sound. From this page.

ensor writes wrote in to send us a link to a bit talking about denser HDs from Seagate. 16 billion bits of data per square-inch on a HD platter with 5 platters per disk for a total of about 100 gigs. Supposedly will be available before the end of the year. This is pretty cool- I like the idea of having enough MP3s locally so I can go long stretches of time without reruns. Long stretches like... March.

biggles writes "Seagate have announced new 50 Gb Barracuda drives. Nuff said :) " Not quite... my math says a 50 gig drive can hold close to a month's worth of MP3s...

A division of Seagate Technology, Inc. has announced a new way of increasing disk drive capacity density. Quinta has disclosed key parts of their technology, which they call Optically Assisted Winchester (OAW) technology to make a practical magento-optical disk that is capable of holding 40GB/square inch. The new technology uses mirrors, a new servo system, and other methods to allow these large capacities.
