This update brings the maximum capacity to 4TB and includes a SAS line as well. SATA connectivity will be 6Gb/sec, while SAS will employ dual port full duplex connectivity for the higher end enterprise sector. These drives appear to use the same platter capacity scheme employed by the recent WD Red Series, though the PR blast states 800GB/platter. I'm awaiting clarification on that point, as the math doesn't seem to work out evenly. Pricing is at a premium for these models, as they are intended for enterprise use. Mid to high $400's for SATA and SAS. Pricey, but still 1/10th of current good deals on SSDs.

Western Digital-owned Hitachi Global Storage (HGST) recently announced that it is pursuing the mass production of helium-filled hard drives. The culmination of six-plus years of research and development, Hitachi’s engineers have come up with a workable solution to craft a sealed enclosure to contain the helium and internal drive hardware over the long term and in a way that can be mass produced. While the company is not ready to talk specifics or announce individual products, HGST (Western Digital) is going on record in stating that its helium-filled “hard drive platform” will offer up performance, power efficiency, and capacity improvements in a 3.5" form factor (with up to seven platters) sometime in 2013.
Don't try this at home folks, it won't actually work :).
The current crop of hard drives have small holes on the top to allow air pressure equalization, as the drives are not a fully-sealed design (and is why dunking them in oil is a bad idea). The proposed helium-filled hard drives would change that design, by being fully sealed from the outside environment after being filled with the noble gas. Steve Campbell, CTO at HGST stated the following in the company's press release:
“The benefits of operating a HDD with helium fill have been known for a long time. The breakthrough is in the product and process design, which seals the helium inside the HDD enclosure cost effectively in high-volume manufacturing,”
But why exactly is helium better for hard drives? In short, the gas is one-seventh (1/7) as dense as the air around us. This reduction in density allows for the platters to spin faster, or at the same spindle speeds at today's drives while experiencing less resistance and turbulance from versus an air-filled hard drive. Thanks to the reduced drag force, Hitachi can pack the platters closer together, which means that it can place more platters into the 3.5" hard drive form factor than ever before – up to seven with the current design. Further, the motor does not have to work as hard to drive the platters which results in quieter operation and more power savings. HGST also claims that using helium allows for better thermal conductivity, and allows the helium-filled hard drives to run up to 4°C cooler than an equivalently-configured air-equalized drive. Granted, 4°C is not that much of an improvement when looking at a single drive (or even a few in a desktop system), but it can add up to some decent cooling savings when these drives are utilized in datacenters.
Hitachi Global Storage does not yet have any specific products to announce publicly, but the company did offer up a few performance numbers that certainly seem promising – an in line with the company's goal of reducing the "total cost of ownership," or TCO. In addition tot he temperature improvements, the company claims up to 23% power reduction versus air. And when HGST factors in its seven-platter design, they have managed to bring the Watts-per-Terabyte (W/TB) 45% versus current drives. Assuming the helium-aided hard drives use the same (or more) amount of platter area as the company's previous drives, Hitachi/Western Digital could offer up to 7TB hard drives when combined with the company's 1TB per platter areal density improvements.
It has the potential to get even better, however. Should the engineers be able to integrate Heat Assisted Magnetic Recording (HAMR) – similar to what Seagate is pursuing – helium hard drives could offer up approximately 85TB 3.5" drives thanks to the additional two platters. Previously, Seagate envisioned up to 60TB HAMR hard drives in the 3.5" form factor. Those numbers are fairly far off in the future (and theoretical), however. On the other hand, Seagate believes that 6TB HAMR hard drives are reasonably close to public consumption, and if a HAMR drive could also benefit from the extra platters, potential spindle speed improvements, and power savings of using helium, I think 8TB+ is not out of the question while using less power than a traditional air-equalized (not sealed) 6TB HAMR-equipped hard drive.
Extremetech does bring up an interestng point about pricing, though. Mainly that helium is much more expensive than simply using the air around us! And as it is used up, it will only get more expensive, which are likely costs that will be passed onto consumers. Fortunately, it should not be too much of a premium that customers would have to pay (over a traditional hard drive) because a 3.5" hard drive will need only a small amount of the helium gas to realize the benefits, according to PC Perspective's resident storage guru Allyn Malventano.
What do you think about the prospects of a heluim-filled hard drive? Will we see such devices within our lifetimes, and just how much will these things cost? I suppose we'll have to wait until next year to find out!

Tagged: idf, idf 2012, western digital, wdc, 5mm, hybrid hdd
At the Technology Showcase yesterday during IDF I got see in person the new Western Digital hybrid hard drives that will combine a single platter spinning disk with a NAND flash for a hybrid solution at under 5mm thick.
You can see that is barely enough z-height for a standard installation screw and this will really help get larger amounts of storage into thinner devices. WD will have it available in 500GB and 1TB versions though the 1TB model will come in a slightly higher 7mm variety.
The WD Blue models will be spinning disk only while the WD Black will combine as much as 32GB of flash memory but it could vary based on the specific OEM request and considerations.
Another requirement of this new form factor is the need for a new connector, conveniently named SFF-8038, that handles both power and data.
We are still waiting for pricing information, but another wave of hybrid technology looks to be on its way!

We took a look at the 1TB VelociRaptor back in April. Well now Western Digital went and stuck a pair of them into an oversized My Book chassis, connected it via Thunderbolt, and voala:
This is a nice little external storage device that can be configured as a RAID 0 or 1. My Book Duos can even be daisychained to support RAID 10! Daisychaining allows up to four My Book Duos to be connected simultaneously. The price is a bit steep, but seems to be in-line with other Thunderbolt enabled products. More to follow once we get a sample in for review!

Tagged: hdd, toshiba, western digital, 3tb, Warranty, sad
As has been mentioned previously on PC Perspective the current trend of HDD manufacturers reducing the length of warranty is not being well received, though with only three manufacturers left consumers have little choice in the matter. At least with Western Digital, you are more likely to get a 3 to 5 year warranty than you are a single year. That negative feedback obviously hasn't fazed Toshiba, who are using the WD plants they purchased earlier this year to manufacture 1.5, 2 and 3TB HDDs, 3.5" in size and available in both 7200 and 5400RPM models and offering 1 year of warranty. In short, a factory which was previously capable of providing a 5 year warranty on spinning disks for your long term storage now offers a shorter warranty than the SSD manufacturers who are poised to replace them. The Inquirer offers more on this depressing topic here.
"Toshiba, the distant third vendor in the storage industry, was given the chance to buy part of Western Digital's hard drive business when it wanted to appease regulatory bodies to approve its purchase of Hitachi. With some of Western Digital's plants, Toshiba is now set to launch a range of 3.5in hard drives topping out at 3TB."

Tagged: western digital, WD, TLER, red, raid, hdd
This morning I received a tweet about WD Red drives not supporting Time Limited Error Recovery. TLER is the feature which allows a RAID comprised of Reds to much more gracefully handle drive failures and/or read errors. It's carried down from enterprise drives like the RE4 and RE4-GP.
I'm posting this quick note here to let the masses know that the Red drives *do* in fact support TLER. It's a primary component of NASware - the NAS aware firmware that drives the Reds. Here's the official reply I received from Western Digital:
WD does enable intelligent error recovery controls, which is not the same as a desktop drive. WD's exclusive NASware technology is built in each WD Red drive, which reduces the concern with using desktop drives in a RAID environment.
More info on details of NASware can be found here: http://www.wd.com/en/products/
Western Digital has assured me they are tracking down where the miscommunication occurred.
Introduction and Internals
I'm going to let the cat out of the bag right here and now. Everyone's home RAID is likely an accident waiting to happen. If you're using regular consumer drives in a large array, there are some very simple (and likely) scenarios that can cause it to completely fail. I'm guilty of operating under this same false hope - I have an 8-drive array of 3TB WD Caviar Greens in a RAID-5. For those uninitiated, RAID-5 is where one drive worth of capacity is volunteered for use as parity data, which is distributed amongst all drives in the array. This trick allows for no data loss in the case where a single drive fails. The RAID controller can simply figure out the missing data by running the extra parity through the same formula that created it. This is called redundancy, but I propose that it's not.

** Note ** - Full review has been posted HERE!
Today Western Digital launches their Red series of hard drives. These are basically Caviar Greens that are specificially tuned to operate in small RAID configurations - namely home and small business NAS solutions containing up to 5 drives. These drives carry over some of the features present on Western Digital's Enterprise lines while adding a few of their own.
We got samples of the Red in yesterday evening, so instead of going on with conjecture derived from the news post, I'll hit you with the new features and a bit of my initial impressions from our early benching:
- Extremely quiet operation thanks to a new dynamic balancing mechanism built into the spindle motor hub. The drive essentially re-balances itself on-the-fly as temperatures change, etc.
- Seeks are equally quiet - quiet enough that a bunch of these doing random access outside of an enclosure would barely be audible from only a few feet away.
- Great sequential throughput (~150MB/sec at start of disk, ramping down to ~65MB/sec at the end).
- Random access times in the 20ms range - likely due to the very quiet seeking mechanism.
- Red Series drives will all be advanced format (i.e. internally addressed by 4k sectors).
- Reds will all be 1TB/platter, available in 1, 2, and 3TB capacities. This gives similar throughput figures regardless of capacity purchased.
- 3-year warranty, with a 24/7 support hotline specifically for Red owners.
- Red drives feature a QR code on the label to assist with any support issues down the road.
I'm not kidding about the quiet operation. The only sound the Red makes is reminiscent of a DVD spinning at low speed, in a sound deadening enclosure. There is no motor whine whatsoever and the head actuator is nearly inaudible. I have to almost lay my head on the drive to tell it is seeking at all.
A full review with all of the gory details will be up later today. For now I leave you with the WD press release after the break, along with this nifty QR to get you more info on the Red Series:

There are quite a few things in the industry to speculate on, from Microsoft's intimating a 'big new thing' next Monday to AMD and the HSA's plans for the future of the industry, but if you want to go for the big one then it is the hard drive industry you should be following. The most recent sign that something big is going on would be the change in warranty length on consumer drives from the two remaining players, both of which now offer a 1yr warranty. That is a vast reduction from previous 3yr and 5yr warranties and while it does not necessarily imply these drives will fail any faster it does mean they offer shorter warranties than their competition, the SSD. This could convince a lot of people that paying $1/GB for an SSD is not really that bad of a deal and you can only expect that price to fall, especially on larger sized SSDs.
Also consider the fact that there are only two major HDD manufacturers left, Seagate and Western Digital. This defragmentation of the industry has been going on for quite a while now, resulting in those two manufacturers owning their competitions resources and IP and pretty much being able to determine what the market will provide and at what cost to the consumer. That has lead to the rather counter-intuitive profits that these two, especially Western Digital, made over the past year. You would not expect a company which lost its manufacturing capabilities to the Thai floods to see a 230% increase in profit, yet that is exactly what happened from March 2011 to March 2012. Seagate held their first place spot over the same time period, with higher volume sales contributing to that success with their prices only rising 20% instead of the 40% they threatened during the supposed supply difficulties.
The HDD market seems to be on its way out, not just because ultraportable devices chose SSDs over HDDs but also because the average consumer has come to the realization that while having a few terabytes of storage is nice for long term storage they really do not need it, especially on a device which does not have long term support. The Inquirer smells something foul in the air and comments on this topic here.
"Seagate, Western Digital and to a lesser extent Toshiba are starting to see free market economics - or as close as it gets - show their strategy of consolidation and profiteering. With the number of solid state disk (SSD) in the low teens, prices are falling steeply while hard drive makers rely on artificially high prices and shorter warranties to make a quick buck."
