Western Digital has extended its Red line with 5 and 6TB models, sporting 1.2TB per platter. Performance is expected to be slightly improved over the older / smaller capacities of the Red. The upgraded line will use an improved 'NASware 3.0' firmware, which makes improvements to Western Digital's software based vibration compensation. These improvements mean WD can now support up to 8 Reds in a single chassis (up from 5 with NASware 2.0).
Also announced was the new Red Pro line, available in capacities up to 4TB. The Red Pro is just as it sounds - a 'Pro' version of the Red. This model borrows more features from WD's enterprise line, making it very similar to an SE series HDD. Imagine a Red, but at 7200RPM and more aggressive seek times. The Red Pro also borrows the enterprise-grade 5-year warranty and is supported in chassis up to 16 bays, thanks to built-in hardware vibration compensation. When all is said and done, the Red Pro is basically a WD SE with firmware tweaked for NAS workloads.
We typically have our WD reviews post right at the NDA. On this piece, we opted to hold back as we've been working with Western Digital on some abnormal performance results we saw with the 6TB Red. Below are the results seen in Iometer. Note that the 6TB Red failed to demonstrate the expected 'ramp up' seen with other drives. HDDs normally show increased performance as Queue Depth increases. This is because the HDD controller is able to see multiple pending requests and optimize its access pattern. The more commands in the queue (higher QD), the more the HDD can optimize the pattern, and therefore the higher resulting IOPS seen.
As you can see above, the 6TB Red appears to behave as if NCQ is disabled. Some might argue (in reviews that have already published) that the drive still performs well, but the plain truth of the matter is that a HDD effectively operating without NCQ removes the drives ability to scale when multiple commands are issued. Any test issuing more than one command simultaneously will see a lesser result as compared to a properly configured drive, so things like streaming multiple videos or several users actively simultaneously accessing a NAS will see a negative impact on performance.
The 4TB Red Pro did not demonstrate the issues noted above, and Western Digital has just issued this statement in response to our feedback. Here it is:
WD has learned that initial production units of WD Red 5* and 6 TB drives perform below our expectations in random-read benchmark tests when measured with specific testing software. We have found a configuration setting to be causing these particular test results, for which we are developing a firmware update to correct the configuration setting. In the intended application -- multi-drive NAS systems -- the drives have performed to our high expectations in WD’s labs and by our system partners; users will experience normal WD Red performance.
WD is committed to providing optimally performing storage products, designed for intended applications, and we will have a firmware update available through the WD Red Product Customer Service support line as it becomes available.
*Limited quantities of 5 TB have shipped with the earlier configuration setting.
We have decided to publish the full article covering both new drives, including the 6TB Red in its (currently shipping) misconfigured form. It will go live once I add the necessary verbiage explaining the misconfiguration seen on the 5TB and 6TB Red.
Stay tuned for that piece later tonight (**EDIT** our review is now live **EDIT**), as well as a follow-on piece to be published as soon as we have the updated firmware from Western Digital.

Introduction and Packaging
Late last year, Western Digital launched their My Cloud series, first with a single-drive My Cloud, and immediately followed up with a beefier small-office product, the 4-drive My Cloud EX4. Then earlier this year, they filled My Cloud gap (so to speak), with a 2-drive variant of the EX4 - the My Cloud EX2. As the EX2 was more of a business type of NAS, it commanded a bit of a price premium as compared to competing 2-bay NAS devices. The logical solution is was for WD to expand the standard My Cloud lineup upward by adding a 2-bay device to their existing consumer line.
The My Cloud Mirror is very similar to the My Cloud EX2. You get the bulk of the same features as compared with the EX2, but with some of the more workstation / enterprise features removed. Here's a couple of slides to help explain those differences:
Packaging is simple, with only a power adapter, ethernet cable, and quick start guide needed.
Athlon and Pentium Live On
Over the past year or so, we have taken a look at a few budget gaming builds here at PC Perspective. One of our objectives with these build guides was to show people that PC gaming can be cost competitive with console gaming, and at a much higher quality.
However, we haven't stopped pursuing our goal of the perfect inexpensive gaming PC, which is still capable of maxing out image quality settings on today's top games at 1080p.
Today we take a look at two new systems, featuring some parts which have been suggested to us after our previous articles.
|AMD System||Intel System|
|Processor||AMD Athlon X4 760K - $85||Intel Pentium G3220 - $65|
|Cores / Threads||4 / 4||2 / 2|
|Motherboard||Gigabyte F2A55M-HD2 - $60||ASUS H81M-E - $60|
|Graphics||MSI R9 270 Gaming - $180||MSI R9 270 Gaming - $180|
|System Memory||Corsair 8GB DDR3-1600 (1x8GB) - $73||Corsair 8GB DDR3-1600 (1x8GB) - $73|
|Hard Drive||Western Digital 1TB Caviar Green - $60||Western Digital 1TB Caviar Green - $60|
|Power Supply||Cooler Master GX 450W - $50||Cooler Master GX 450W - $50|
|Case||Cooler Master N200 MicroATX - $50||Cooler Master N200 MicroATX - $50|
(Editor's note: If you don't already have a copy of Windows, and don't plan on using Linux or SteamOS, you'll need an OEM copy of Windows 8.1 - currently selling for $98.)
These are low prices for a gaming computer, and feature some parts which many of you might not know a lot about. Let's take a deeper look at the two different platforms which we built upon.
First up is the AMD Athlon X4 760K. While you may not have known the Athlon brand was still being used on current parts, they represent an interesting part of the market. On the FM2 socket, the 760K is essentially a high end Richland APU, with the graphics portion of the chip disabled.
What this means is that if you are going to pair your processor with a discrete GPU anyway, you can skip paying extra for the integrated GPU.
As for the motherboard, we went for an ultra inexpensive A55 option from Gigabyte, the GA-F2A55M-HD2. This board features the A55 chipset which launched with the Llano APUs in 2011. Because of this older chipset, the board does not feature USB 3.0 or SATA 6G capability, but since we are only concerned about gaming performance here, it makes a great bare bones option.
Introduction and Packaging
Last October, Western Digital launched the My Cloud. This device was essentially a network connected version of their My Book line of external hard drives, but with Internet connectivity and apps that could reach back to the My Cloud even when you were away from home. One month later, WD launched the My Cloud EX4, a much beefier version which supported redundant arrays of 4 hard disks, redundant network and power, and a load of other features. There was a rather large gap in features between these two devices, as the only RAID option was more of a small business one. Today Western Digital closed that gap:
The My Cloud EX2 is essentially a My Cloud, but with dual drive bays, and a few additional features. Check out this projected trend below:
You can see there was a definite void in the 2-drive range that needed filling. With those two drives, you get a few options for redundancy or capacity+speed:
All standard RAID options for a 2-bay appliance are met here, though the vast majority of users should opt for the default RAID-1 mirrored set.
Packaging is simple here with only a power adapter, ethernet cable, and quick start guide needed.

Western Digital has several lines of hard disks to choose from. You have Greens, Blues, Blacks, enterprise RE's, and even ones named after dinosaurs. Then came a mix of RE and GP in the form of the RE4-GP. Then came the Red series, which carried some more of the enterprisey features from the RE series over into a NAS-tailored drive that sipped power like a Green. Then there was the AV-GP which took a green and tweaked the firmware to better handle multiple video streams being read to and written from the disk simultaneously.
You'd figure they had every possible angle covered, but apparently there was a hole to fill. Turns out the home / small business surveillance market is a bit of a big deal. We're talking about those security systems you see capturing 16 or even 32 video streams simultaneously. Add the fact that these larger systems tend to store their streams to a RAID as opposed to a single disk. What was needed was a drive capable of handling a greater number of simultaneous streams than an AV-GP, while also carrying over the RAID features of the Red, and doing so without driving costs into the enterprise territory of the SE/RE.
Behold the solution:
The WD Purple is an Advanced Format HDD that is optimized for recording up to 32 HD video streams simultaneously:
Writing 32 separate streams to a hard drive would usually lead to the heads thrashing about, trying to keep up with what appears to be random writes. The Purple has much smarter firmware that has been tuned for this specific purpose (seen above maintaining 50% idle time while handling 32 HD streams). While these firmware optimizations would hurt performance in normal consumer use, for heavy surveillance usage, this is likely the closest you can get to SSD performance for this application - without high cost/GB of using solid state as a solution to such a capacity hungry problem.
Speaking of cost/GB, Purple drives are quite reasonable, starting at $89 for 1TB up to $199 for the flagship 4TB capacity.
Press blast after the break:

There are still many times when having a huge amount of storage at a low price is more important than having the speed of an SSD and the Western Digitial Black family of drives is perfect for those scenarios. This 7200RPM HDD has five 800GB platters and a 64MB cache in the 4TB model TechARP reviewed though you can get smaller models if you so desire. While the drive will not compete against and SSD you can see in the review that this drive tops the other platter based models performance by a noticeable margin. If you need a large amount of space but can't pay around $1.00/GB then don't forget that HDDs are also still evolving.
"The new-generation Western Digital Black family differs from the previous generation by its use of Advanced Format Technology, which allows for greater capacity and throughput. The new Western Digital Black family now consists of five models, which differ only in their storage capacities."

Last night at the PEPCOM Digital Experience, we swung by Western Digital's booth. While there are no new launches at CES, it's always nice to see the full spread all laid out on display:
4TB Green and Black, 1TB Blue, Ultra Slim drives, and of course the Black2.
The other table shifts to backup and external storage, scaling up through the My Cloud to the larger EX4.
My eye was also caught by the behemoth of a router that is the Linksys WRT1900AC!
This beast is way more than an evolution on the old WRT54G. While there are four antennas, the dual band Marvell radios are only 3x3 capable. They can, however, choose among the four antennas to achieve the best possible throughput. The '1900' rating comes from 1300Mbps (5GHz) + 600Mbps (2.4GHz). This router will be Open-WRT capable out of the box, so you can expect the folks like DD-WRT and Tomato to have usable firmware built very shortly after launch, which is expected sometime around April of this year. Let's check out the ports:
Not only is there USB3, but we also have eSATA for even faster connectivity. Throughput to connected storage should be stellar as the on-board CPU will be a 1.2 GHz dual core ARM. Radios and CPU will be cooled by a built-in fan, and Linksys also noted they will be launching an 8 port Gigabit switch in a matching (and stackable) form factor. Open source firmware buff tech note: 128MB Flash, 256MB RAM. MSRP: $299.

Tagged: HAMR, western digital
In the race to increase the areal density of HDDs the tech to work towards is currently Heat Assisted Magnetic Recording as the current shingle technique has helped us increase storage capacity by a small amount but not enough to be the next evolution. Seagate announced their strategy to develop HAMR technology over a year ago but we have yet to see a prototype. Western Digital has just shown off their version of HAMR to a bevvy of journalists, not including The Register, with a working prototype. WD predicts densities reaching 4 terabits per square inch, making an 8TB 2.5" drive a possibility but they have not predicted a release date yet.
think bigger than this
"In September 2012, Seagate boss Steve Luczo gave a presentation using a HAMR technology disk drive. Now, more than a year later, a WD exec has done the same with the company's own HAMR tech drive."

Introduction and Features
Today Western Digital launched an important addition to their Personal Cloud Storage NAS family - the My Cloud EX4:
The My Cloud EX4 is Western Digital's answer to the increased demand for larger personal storage devices. When folks look for places to consolidate all of their bulk files, media, system backups, etc, they tend to extend past what is possible with a single hard drive. Here is Western Digital's projection on where personal storage is headed:
Where the My Cloud was a single drive solution, the My Cloud EX4 extends that capability to span up to four 3.5" drives. When it comes to devices that span across several drives, the number 4 is a bit of a sweet spot, as it enables several RAID configurations:
Everything but online capacity expansion (where the user can swap drives one at a time to a larger capacitiy) is suppoted. While WD has stated that feature will be available in a future update, I find it a bit risky to intentionally and repeatedly fail an array by pulling drives and forcing rebuilds. It just makes more sense to back up the data and re-create a fresh array with the new larger drives installed.
Ok, so we've got the groundwork down with a 4-bay NAS device. What remains to be seen is how Western Digital has implemented the feature set. There is a lot to get through here, so let's get to it.
