Inside the Barracuda Pro are eight platters each 1.75 TB in size and comes with a nice addition to the warranty, if the drive dies before two years have expired you can ship the drive to Seagate and they will attempt to recover your data for free. The Guru of 3D's testing showed the accuracy of the 250MB/sec rating, as expected from a modern SATA HDD. The total warranty is five years and the drive is rated for 24/7 use with a 300TB/yr rating so there are certainly plenty of usages for the drive.
"It's here! We review the Megalodon among the HDDs, the Barracuda Pro 14TB from Seagate is unleashed today, that's a 14.000GB HDD folks! This, by far, is the biggest single consumer unit storage device to date. It might not offer SSD performance, but it certainly isn't slow. It's the year 2018, it's big but with these massive HDD platters, will it be fast enough?"

No matter what you need it for, Seagate can provide supersized storage for your needs. To lead with the most important information, the IronWolf and IronWolf Pro 14TB will run you $529.99 and $599.99 respectively, a 14TB BarraCuda Pro sits at $579.99, a SkyHawk14TB a mere $509.99 and the Exos X14 at $614.99. These prices might sound expensive until you think how much 14TB of NVMe storage will cost you.
The IronWolf and IronWolf Pro as designed to be used in a NAS, with firmware designed to provide reliability in a variety of arrays along with health management and recovery tools baked right in. The drives are rated at 300TB/year, with a 5 year warranty on the Pro and 3 years on the other.
The Barracuda Pro is one you are more likely to grab, the 7200 RPM HDD has 256MB Of cache which allows up to 250mb/s data transfer rates depending on the task you require of it. You will get a 5 year warranty to ensure you get your moneys worth out of the drive.
The Skyhawk is great for surveillance systems, the 14TB allows you to capture over 9000 hours of H.264 video with 1M pixels, medium quality, at 15FPS; with support for up to 64 attached cameras. It would also make a great drive for a DVR if you intended to record every single moment of TV you missed while on vacation. The 3 year warranty in part reflects the expectation you will be writing to this drive 24/7/
Last is the Exos X14, which you can order already installed into the chassis you see above, with up to a 1.4PB of storage. The helium-based design is not only for longevity, Seagate claims a 10% reduction in weight versus other drives.
Full PR below the fold.

Following up on the prior release of a 14TB SMR (shingled magnetic recording) HDD, WD has launched a PMR (parallel magnetic recording)version of the same - the Ultrastar DC HC530:
While the new model does not yet incorporate MAMR, it does couple PMR with TDMR (two-dimensional magnetic recording), which gives a slight boost to platter density, reaching over 900 Gbit/sq. inch. The DC HC530 naming is a departure from the previous HGST Ultrastar line products, which were labeled as 'He8', 'He10', etc. High-level specs are as follows:
- Rotational speed: 7200 RPM
- Data buffer: 512MB
- Seek time (typ): 7.5 ms
- Sequential transfer rate: 267 MB/s (start of disk)
- Available sector sizes: 512e (advanced format emulation), 4Kn (4KB sectors)
- Warranty: 5 years
The SAS models offer double the interface throughput (12Gbps) and some additional custom sector sizes but require higher operating power to drive that faster interface. While track linear density is high enough (at least at the start of the disk) to saturate a SATA 3Gbit link, SATA 6Gbit and SAS 12Gbit links will still see a cache-hit benefit from the drives' relatively large 512MB data buffer.

During the Open Compute Summit Seagate showed off a new drive in its Helium-filled Exos X lineup that offers up 14TB of storage in a 3.5-inch SATA hard drive package. The aptly named Exos X14 is a low power 7200 RPM drive that utilizes PMR rather than the more exotic methods (shingled, HAMR, ect) and is a drop-in replacement that Seagate claims allows up to 40% more storage space per rack than previous drives – up to 3,360 TB per rack!
The drive is aimed at datacenter customers and cloud storage providers clamoring for fast-enough affordable storage. The Exos X14 platform is expected to use a whopping 9-platters each holding 1.55 terabytes. Beyond that, Seagate is not sharing exact specifications except to say that it has bested the sustained transfer rates of the Exos X12 and competitors and has leading and reliable random I/O performance that has been optimized for hyperscale environments (so take that for what you will) likely thanks to the increased storage density.
Seagate did note that the new drives support Seagate Secure encryption and the drive is rated for FIPS 140-2 / Level 2 and ISO/IEC 15408 certifications so at least in theory it meets a minimum level of IT security practices in the methods it uses to protect the data stored on it.
A research study performed by IDC and sponsored by Seagate found that worldwide data creation could hit up to 163 Zettabytes (163 trillion Gigabytes!) by 2025 (10-times the amount of data created last year) which is mind-boggling. Even if the reality is half of that, that’s still an absolutely staggering amount of data that needs to be stored somewhere and both spinning rust and expensive flash are going to have to make some significant advancements to get to that point – and to that point with an acceptable TCO.
The Exos X14 is expected to start shipping to datacenter customers this summer and is currently being sampled to select partners like Baidu and Facebook (Facebook was showing off a server packed with the drives at OCP 2018).
Also interesting is Seagate’s announcement of “Mach.2” multi-actuator technology and its advancements into making HAMR (heat assisted magnetic recording) more reliable both of which are going to be important for the future.

Tagged: PMR, toshiba, helium, Hard Drive, enterprise, cmr, cloud storage, 14tb
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 is raising the enterprise hard drive stakes once again with the announcement of a 14 TB 3.5” hard drive. The HGST branded Ultrastar Hs14 uses fourth generation HelioSeal and second generation host-managed SMR (shingled magnetic recording) to enable a 14 TB drive that is just as fast as its smaller capacity enterprise predecessors despite the impressive 1034 Gb/sq in areal density. Western Digital claims the new hard drive offers up 40% more capacity and twice the sequential write performance of its previous SMR drives.
The 3.5” SMR hard drive comes in SATA 6Gbps and SAS 12 Gbps flavors with both equipped with 512 MB cache, operating at 7200 RPM, and supporting maximum sustained transfer speeds of 233 MB/s. The enterprise drive is geared towards sequential writes and is intended to be the storage target for big data applications like Facebook, video streaming services, and research and financial workloads that generate absolutely massive amounts of raw data that needs to sit in archival storage but remain easily accessible (where tape is not as desirable). According to the data sheet (PDF), it is also aimed at bulk cloud storage and online backup as well as businesses storing compliance, audit, and regulatory records.
For those curious about Shingled Magnetic Recording (SMR), Allyn shared some thoughts on the technology here.
Western Digital rates the drive at 550 TB/year and supports the Hs14 with a five year warranty. The drive is currently being sampled to a small number of OEMs with wider availability to follow.
