Toshiba recently took the wraps off of a new hard drive series aimed at the enterprise market. What makes the MG07ACA series interesting is that Toshiba is offering a 14 TB 3.5” drive without resorting to using Shingled Magnetic Recording. Instead, the new MG07ACA series uses standard recording methods (CMR) and nine ~1.556 TB PMR (perpendicular magnetic recording) platters in an helium filled hermetically sealed enclosure to hit 40% more capacity and up to 50% better power efficiency than the previous MG06ACA (10 TB) series. The new drives are also important because they represent the first foray into helium filled hard drives for Toshiba following the company pushing air breathing drives to the limit with its seven platter models.
The new drives are standard 7200 RPM models with 256 MB of cache and a SATA 6 Gbps interface. The 14 TB model is able to hit 260 MB/s sustained transfer while the slightly lower areal density of the 12 TB model puts it at a 250 MB/s transfer speed maximum. They are able to hit 167 random 4K read IOPS and 70 random 4k write IOPS (which is fun to compare to even the slowest SSDs today, but these drives aren't for random workloads). Toshiba rates the drives at a fairly industry standard 550 TB per year workload and 2.5 million hours MTBF with a five year warranty. Toshiba is reportedly using its own laser welding technology to seal the drives and keep the helium contained. The MG07ACA drives are offered in emulated 512 (512e) and 4k native sectors with the 512e models featuring Toshiba Persistent Write Cache technology to prevent data loss in the event of power failure while the drives are executing read-modify-write operations. The power loss protection (PLP) is important for enterprise customers using these drives to upgrade the storage in their legacy software and hardware setups.
The MG07ACA series includes 14 TB 9-disk and 12 TB 8-disk drives. That’s a lot of platters in a single drive, but Toshiba claims that going this route with CMR / PMR reduces the total cost of ownership (TCO) for enterprise customers that are buying up high capacity drives for their cloud storage and big data storage needs. The drives are allegedly more power efficient and trusted in the enterprise market as opposed to the newer shingled drives. I suppose these drives are also useful as they can be drop in upgrades of lower capacity models.
John Rydning, Research Vice President for hard disk drives at IDC was quoted in the press release in saying:
"While enterprise server and storage customers realize that shingled magnetic recording (SMR) technology can improve HDD capacity, the adoption of SMR HDD products into server and storage systems is a transition that will take several years,"
Interestingly the drives offer 1.5 TB / platter in the 12 TB model and a bit more than 1.55 TB / platter in the 14 TB drive. With SMR technology hitting up to 1.75 TB / platter so far, using that could get a 14 TB drive with just 8 platters, but that is still fairly close that I suppose going with the longer track record of non shingled PMR and its reliability is more important to the enterprise customers.
In order to cram 9 platters into a standard 3.5" drive, Toshiba had to make the platters thinner and move to helium instead of air. Specifically, Toshiba is using 0.635mm Showa Denko (SDK) PMR platters that are a mere 1.58mm apart! The drives have Nidec motors on the top and bottom as well as environmental sensors and RVFF (Rotation Vibration Feed Forward) vibration compensation technology which is important when you have nine platters spinning at 7200 RPM in each drive and then hundreds of drives are placed in close proximity to each other in server racks and SANs. The move to helium and thinner platters is a big part of the power savings in this drive with the platters being easier to spin up and exhibiting less flutter moving through the much less dense helium versus air. Toshiba claims that the MG07ACA series uses up to 7.6 watts in normal operation and 4.6 watts at idle (0.32W/GB).
According to AnandTech, Toshiba will begin sampling the new hard drives later this month and will sell the drives to its large enterprise customers within the first half of next year. Once demand from the big data crowd has been met, Toshiba will being selling the drives through distributors which means enthusiasts will be able to get their hands on the drives through normal channels by the end of 2018. Exact pricing and availability have not been announced at this time.

Western Digital increased the capacity of their Red and Red Pro NAS hard disk lines to 10TB. Acquiring the Helioseal technology via their HGST acquisition, which enables Helium filled hermetically sealed drives of even higher capacities, WD expanded the Red lines to 8TB (our review of those here) using that tech. Helioseal has certainly proven itself, as over 15 million such units have shipped so far.
We knew it was just a matter of time before we saw a 10TB Red and Red Pro, as it has been some time since the HGST He10 launched, and Western Digital's own 10TB Gold (datacenter) drive has been shipping for a while now.
- Red 10TB: $494
- Red Pro 10TB: $533
MSRP pricing looks a bit high based on the lower cost/GB of the 8TB model, but given some time on the market and volume shipping, these should come down to match parity with the lesser capacities.
Press blast appears after the break.

First up is a second generation of HGST-branded SSD products - the Ultrastar SN200. These enterprise SSDs boast impressive specs, pushing random reads beyond 1 million IOPS, coming in 8TB capacity, and if you opt for the HHHL PCIe 3.0 x8 SN260, 6.2GB/s maximum throughput.
Moving into SAS SSDs, the SS200 uses a 12Gbit link to achieve 1.8 GB/s and 250,000 random read IOPS. Write specs dip to 37,000 random as this is a 1 DWPD endurance class product. These are also available in up to 8TB capacities.
Last but certainly not least are preliminary specs for the He12, which boast particularly impressive low QD random write performance and a notable bump in Watts/TB despite the addition of an eighth platter to achieve the 12TB capacity. Note that this is not an archive class product and is meant for continuous random access.
There is also a 14TB model in the lineup, but that is an archive class model that is essentially the He12 with Shingled Magnetic Recording enabled.
Press blast appears after the break.
Introduction and Specifications
Barracuda is a name we have not heard in a good while from Seagate. Last seen on their 3TB desktop drive, it appears they thought it was time for a comeback. The company is revamping their product lines, along with launching a full round of 10TB Helium-filled offerings that cover just about anything you might need:
Starting from the center, IronWolf is their NAS drive, optimized for arrays as large as 8 disks. To the right is their surveillance drive offering, the SkyHawk. These are essentially NAS units with custom firmware optimized for multiple stream recording. Not mentioned above is the FireCuda, which is a rebrand of their Desktop SSHD. Those are not He-filled (yet) as their max capacity is not high enough to warrant it. We will be looking at those first two models in future pieces, but the subject of today’s review is the BarraCuda line. The base 3.5” BarraCuda line only goes to 4TB, but the BarraCuda Pro expands upon those capacities, including 6TB, 8TB, and 10TB models. The subject of today’s review is the 10TB BarraCuda Pro.

This drive was initially paper-launched back in January, but now Seagate claims it is shipping in volume. While that original release and today’s update both lack performance specs, there are a few interesting tidbits sprinkled in there:
- This is a CMR drive, not SMR, meaning that it can be written randomly without any of the batch write penalties of Shingled Magnetic Recording.
- ‘Advanced write caching capabilities’ hints at a form of the media cache tech present in the HGST He6/He8 and also recently adopted by the WD 8TB Gold.
- The Seagate 10TB release from earlier this year stated that his model will be a 7-platter design with 14 heads. Helium enables thinner platters, and 7-platter designs began appearing in the HGST He6.
- At nearly 1.5TB per platter and an assumed spindle speed of 7200 RPM, we can infer that the base specs should be reasonably impressive.
Introduction and Specifications
Storage devices for personal computers have always been a tricky proposition. While the majority of computer parts are solid state, the computer industry has spent most of its life storing bits on electromechanical mechanical devices like tapes and floppy disks. Speaking relatively, it was only recently (less than a decade) that solid state storage became mainstream, and even today the costs of flash production make rotating media the better option for bulk data storage. Hard drives are typically vented to atmosphere, as the Bernoulli Effect is necessary as part of what keep the drive heads flying above the rotating platters. With any vented enclosure, there is always the risk of atmospheric contaminants finding their way in. Sure there are HEPA-class filters at the vent holes, but they can’t stop organic vapors that may slightly degrade the disk surface over time.
By filling a hard disk with an inert gas and hermetically sealing the disk housing, we can eliminate those potential issues. An added bonus is that if Helium is used, its lower density enables lower air friction of the rotating platters, which translates to lower power consumption when compared to an equivalent air-filled HDD. Ever since HGST released their Helium filled drives, I’ve been waiting for this technology to trickle down to consumer products, and Western Digital has recently brought such a product to market. Today we will be diving into our full performance review of the Western Digital 8TB Red.
Compared to the 6TB Red, the 8TB model doubles its cache size to 128MB. We also see a slight bump in claimed transfer rates. Idle power consumption sees a slight bump due to different electronics in use, and power/capacity figures check out as well (more on that later as we will include detailed power testing in this article).

Seagate updated their Enterprise Capacity line of HDDs this morning with a monster of a 10TB unit:
To achieve this capacity, Seagate switched over to a sealed, Helium filled design (similar to what HGST has been doing for a few years now). Since filling the space of a HDD with Helium helps reduce head flutter and platter thickness, Seagate was able to fit seven platters into a standard 3.5" housing. As an additional note, this drive uses the same PMR (Perpendicular Magnetic Recording) as other recent generation units, and not the SMR (Shingled) employed in their recent 8TB Archive HDD. PMR is a good thing here, as it enables random write access without the performance penalty incurred when attempting the same on an SMR drive.
The Helium filling pushes the MTBF up to 2.5 million hours. Unfortunately the release was light on the other details, and we do not have pricing as of yet, but we will certainly be keeping an eye on this one. Seagate states they are 'shipping to select customers', but given that those customers are ordering by the truckload, it may be some time before we see them in the OEM aftermarket channels.

The new generation of helium filled HDD from HGST take their longevity seriously, rating them at 2.5 million hours MTBF. This generation also has 7 disks squeezed into the shell, with current capacities reaching 8TB and a shingled 10TB model currently being tested for release later this year. The increased life and storage density are only part of the benefits that helium brings, 23% lower operating power and temperatures 4-5°C lower than traditional drives will also have an impact on data centre operating costs. In their article The Register did ask how long the HelioSeal will keep the helium contained and while they did not get an exact figure, the 5 year warranty gives you a good idea of a lower limit.
"HGST has announced second-generation helium drive tech after shipping a million gen-1 Helium drives and upping field reliability by 15 per cent."

Enthusiasts are wholeheartedly adopting SSDs for their storage media of choice with HDDs relegated to long term storage of infrequently accessed storage. For SMB and enterprise it is not such an easy choice as the expense to move to a purely SSD infrastructure is daunting and often not the most cost effective way to run their business. That is why HDD makers continue to develop new technology for platter based storage such as HAMR and shingled magnetic media in an attempt to speed up platter drives as well as increasing the storage density. Today at The Register you can read about a variety of technologies that will keep the platter alive, from Seagate's cached Enterprise Turbo SSHD, HGST's helium filled drives and the latest predictions on when HAMR and SMR drives could arrive on the market.
"At a briefing session for tech journos yesterday, Seagate dropped hints of new solid-state hybrid drives (SSHDs) - which combine a non-volatile NAND cache with spinning platters - and a general session about Shingled Magnetic Recording (SMR) and Heat-Assisted Magnetic Recording (HAMR)."

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!
