Western Digital is expanding its data center hard drive offerings with the reveal of a 15TB model based on fourth generation HelioSeal and second generation Host Managed SMR (Shingled Magnetic Recording) technology. The new 15 TB Ultrastar DC HC620 is aimed at data center customers doing surveillance, object storage for cloud services, streaming media storage, online backup and archival storage, and other sequential write focused tasks. The 7200 RPM hard drive comes in SATA (6Gbps) or SAS (12Gbps) flavors, but is not a direct drop-in replacement for just any drive as it works with host managed SMR to optimize how data is written to the drive which needs to be sequentially to get any amount of decent performance out of it. Random performance (writes in particular) isn’t great in other words, but it does offer up to 31% lower idle watts/TB than prior generation drives while delivering respectable (for mechanical drives) sequential performance and areal density with 900TB of storage being able to fit in a 40U (60-unit) rack or 40TB more compared to using 14TB drives

Western Digital’s 15 TB DC HC620 (PDF)is a 7200 RPM hard drive with a 512 MB buffer. It is rated at 255 MB/s sustained transfer rates, 4.16 ms average latency, and 7.7ms read and 12ms write seek times. Further, the datacenter focused drives are rated for 550TB per year with a 2.5 million hour MTBF and a five year warranty.
 
While enthusiasts will not be using these new SMR drives, they may well be being used by the various cloud service providers and their services that end users take advantage of. It is interesting to see that shingled magnetic recording is still being developed and the increasing amount of data that is able to be crammed into the same 3.5-inch hard drive form factor. I am looking forward to future technologies like MAMR and HAMR as well to see just how far spinning rust can be pushed. While end users are enjoying the speed of solid state storage, hard drives are still alive and well in the data center thanks to TCO (total cost of ownership) and TB/watt/area metrics and the drive to optimize them being paramount. According to Western Digital, global data storage demands are going to approach 100 zetabytes within the next five years so I am curious how we will end up storing all of that and the kinds of technologies involved!
 

Western Digital Launches 14TB Enterprise Hard Drive for Big Data

Tagged: western digital, SMR, hgst, HelioSeal, big data, 14tb

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.

Since their acquisition of SanDisk and recent wrapping up of a long-time integration with HGST's Helium tech, Western Digital took the lid off of a round of product updates this morning.

wd-9-.png

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.

wd-11-.png

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.

wd-16-.png

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.

Not bad HDD progress considering we were just discussing 10TB SMR this time last year. We'll be confirming the performance of these as samples arrive for testing.

Western Digital Reworks Enterprise Lineup, Launches 8TB Gold Datacenter HDD

Subject: Storage | April 19, 2016 - 08:00 AM |
Tagged: Xe, western digital, wdc, WD, se, RE, Media Cache, hgst, HelioSeal, gold, 8TB

Western Digital rolled out their Se / Re / Xe branding back in mid-2013. Since that time, a lot has changed in the rapidly evolving enterprise storage industry. SSDs are encroaching into more of the data center rack space out there, and the need for small capacity 10k and 15k RPM drives is dropping substantially in favor of more power efficient (in power and capacity per dollar), larger spinning disks.

With these winds of change comes today’s announcement from Western Digital:

WD_Datacenter_PRN_graphic.jpg

The new Gold lineup appears to be a merging of old and new product lines. The 6TB and below Re series are essentially being absorbed under the new Gold label, but 6TB will no longer be the top capacity offered to WD enterprise customers. A new 8TB capacity will be offered in the form of a HelioSeal drive. The 8TB model will share more parts with the HGST He8 than WD’s previously released 8TB Red, including HGST’s Media Cache architecture, which should yield a nice boost to sustained random write performance over drives lacking this technology.

The press release does not state this, but I suspect WD will be phasing out their Se and Xe product lines over the coming months in favor of Helium-filled drives of the 5400 (Red) and 7200 (Gold) RPM variety. Fewer lines to manage should help them tighten things up a bit and reduce costs even further over time.

We’ll be reviewing the new 8TB Gold just as soon as samples arrive for testing, so stay tuned!

Full press blast appears after the break.

As we were publishing our full review of the Western Digital Red 8TB, we noted something odd. While the street prices of the bare drives seemed to be a bit high ($333), the WD My Book was on sale for $250. Ryan happened to look them up and discovered that our local Best Buy actually had them available for store pick-up. Since the 8TB Red and My Book 8TB were launched simultaneously, and we were just provided early samples of the 8TB Reds last week, how could there already be 8TB Reds on the shelf just down the street? Could they have shipped some earlier form of the 8TB Red in the external My Book and continued tweaking their NASware algorithms / firmware prior to the Red launching? Our curiosity got the best of us, and we decided to find out.

Sebastian ran out to his local Best Buy and picked up a single WD My Book 8TB model, promptly took it home and ripped it open. I don’t think he even plugged it in first. This is what he found:

Well, that’s not a Red label, but it does say Western Digital, and it’s clearly a HelioSeal housing (common to HGST He Series and WD Red 8TB). One thing that immediately stuck out to me was the model number. WD model numbers have a specific pattern (WD80EFZX), and that number above does *not* follow that pattern. The pattern it does follow, however, is that of the HGST He8 line:

Sebastian noted something else almost immediately. The label looked like it was on top of another one. Peeling this one back showed this pure white label:

…and peeling back *that* label gave us this:

Western Digital Infuses Consumer HDDs with HGST HelioSeal Tech - Increases Capacity to 8TB

Subject: Storage | March 1, 2016 - 08:00 AM |
Tagged: WD, hgst, HelioSeal, He8, He6, He10, 8TB

Helium-filled HDD technology has been around for a few years, but since HGST launched their He series a couple of years ago, Helium has been stuck in the enterprise sector. Western Digital has been in a lengthy merger process with HGST, and I figured (hoped) that it would be only a matter of time before we saw Helium-filled consumer HDDs. I’m happy to report that time is now:

He_8TB_timesquare_RR.jpg

The first product lines to see this expansion will be WD’s external offerings (My Book / My Book Duo / My Cloud / My Cloud Mirror / My Cloud EX2 Ultra) and a few internal lines (Purple / Red / Red Pro). Taking a look at the new housing for the 8TB Red:

WDRed8TB.jpg

…we can tell that it appears to be the same HelioSeal tech used by HGST, right down to the external housing design. Here is an HGST He8 housing for reference / comparison:

HGST-8TB-Ultrastar-He8-Enterprise-HDD-ecomm.png

I’m excited to see He making its way down the product chains, as a sealed HDD enclosure significantly reduces environmental effects on HDD reliability and performance. Helium also means less air friction, causing less heat production and therefore less power consumption. While the capacities are higher, we suspect performance won’t be taking any large leaps with WD’s first generation of Helium filled Hard Disk Drives. We will be testing a few of these once samples arrive and will deliver a full review as soon as possible. Since it appears that Western Digital was holding off on their 8TB capacity point until HelioSeal was integrated, it's a safe bet that their other product lines will receive the same technology and capability in the future.

10TB of helium filled storage from HGST

Subject: General Tech | December 2, 2015 - 01:14 PM |
Tagged: 10TB, hgst, western digital

Western Digital subsidiary HGST had previously released a 10TB drive which used their new shingling technique to reach such high storage densities and meant that there was a limited capacity for rewrites.  They have now released a new 10TB drive which is formatted in a more traditional manner and does not have the same limitations as brought on with the shingling method of design.  The Inquirer also mentions 6TB and 8TB models if you don't quite need 10TB of storage.  No mention of price is made but you can guess that this HDD will be close in price per GB to SSDs, sadly not the price parity we were hoping for.

What helium shortage? I have a bunch stored in my HGST drive

Subject: General Tech | March 26, 2015 - 12:32 PM |
Tagged: hgst, western digital, helium, hdd

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.

CES 2015: Storage Visions Sightings Part 1: HGST He8, DriveSavers, and SanDisk

Many of the storage announcements this year are under embargo until tomorrow or later in the week. Fortunately there was plenty of things on display out in the open - meaning fair game for me to photograph and present to you in this quick photo walkthrough.

DSC06829_resize.JPG

The HGST Ultrastar He8 was on display. This is a 7-platter Helium filled HDD. The lower density atmosphere enables more platters and higher spin speeds without producing too much heat for the drive to handle.

DSC06830_resize.JPG

The added platters also enable a very large capacity of 8TB, all while consuming less power than most other available non-He HDD's, which is attractive for enterprise usage where racks upon racks are filled with these drives.

The display model we saw here was covered with plexiglass, but the DriveSavers folks had one completely open in all of its glory:

DSC06905_resize.JPG

DSC06904_resize.JPG

Seeing the head pack out of a drive is rare, as you're supposed to only get to that point in a clean room environment (unless you don't want your data back, that is). DriveSavers told us the challenge to recovery from an He HDD is getting the Helium back into the housing prior to closing it back up after a failed component replacement. Here's a closer look at that head pack. Note the small logic die built into the ribbon - this component needs to be mounted as close as possible to the heads to minimize interference and signal loss from the very high frequency signal coming from the read heads:

DSC06909_resize.JPG

DriveSavers also has recently announced data recovery capability and partnership with SanDisk. There is a separate announcement we will be covering later in the week, but since we're talking about SanDisk, here is a look at the non-embargoed products we were allowed to show for now:

DSC06899_resize.JPG

From left: UltraDIMM, FusionIO Atomic, Optimus Max, Optimus MAX (opened), Optimus ECO. More interesting here is that SanDisk is able to pack 4TB into the Optimus form factor. They accomplish this by a unique folding PCB design shown below in unfolded form:

That's it for this update, more to follow shortly.
