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 Ultrastar DC HC530 - TDMR 14TB HDD

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:

UltrastarDC-HC530.jpg

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.

WD's press release appears after the break, and more information is available on the Ultrastar DC HC530 product page.

Western Digital Launches 14TB Enterprise Hard Drive for Big Data

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.

Western Digital Launches 10TB Red and Red Pro

Tagged: western digital, wdc, WD, Red Pro, red, NAS, helium, HelioSeal, hdd, Hard Drive, 10TB

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.

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

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!

Introduction and Specifications

Introduction

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).

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.
