Computex 2014: WD Shows SATA Express-based PCIe HDD

SATA Express is an interface to either connect a hard drive to PCIe lanes, or up to two drives via SATA. Obviously, PCIe bandwidth over a cable connection is the real draw. To use the full speed, however, the drive needs to be able to communicate over PCIe. Currently, the standard uses two PCI Express 2.0 lanes (1 GB/s).

Now that Z97 and H97 have launched, WD is set to show off the technology at Computex. The above image is apparently of a dual-drive product, containing 4TB of rotating media and 128GB of SSD memory. I am immediately reminded of the Western Digital Black2 dual drive which Allyn reviewed last November. That product crammed a 120GB SSD into a 2.5" 1TB HDD, which appeared to the system as two separate drives. The drive has "Technology Demonstration" written in red font right on it, but it could be a good representation of what the company is thinking about.

WD also asserts that their prototype uses standard AHCI drivers, for OS compatibility.

If you want to see this product in action, then -- well -- you kind-of need to be at Computex. At some point, you might be able to see it in your own PC. When? How much? No pricing and availability, again, because it is a tech demo.

Western Digital launches surveillance-oriented WD Purple series of 3.5" HDDs

Subject: Storage | February 25, 2014 - 08:00 AM |
Tagged: western digital, wdc, WD, surveillance, Purple

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.

Western Digital:

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:

2014-01-06 22-11-28.JPG

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.

Linksys:

My eye was also caught by the behemoth of a router that is the Linksys WRT1900AC!

2014-01-06 22-12-53.JPG

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:

2014-01-06 22-14-39.JPG

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.

Introduction, Specifications and Packaging

Introduction:

If you're into the laptop storage upgrade scene, you hear the same sort of arguments all the time. "Do I go with a HDD for a large capacity and low cost/GB, but suffer performance"? "I want an SSD, but can't afford the capacity I need"! The ideal for this scenario is to combine both - go with a small capacity SSD for your operating system and apps, while going with a larger HDD for bulk storage at a lower cost/GB. The catch here is that most mobile platforms only come with a single 2.5" 9.5mm storage bay, and you just can't physically fit a full SSD and a full HDD into that space, can you? Well today Western Digital has answered that challenge with the Black2 Dual Drive:

Yup, we're not kidding. This is a 120GB SSD *and* a 1TB HDD in a single package. Not a hybrid. Two drives, and it's nothing short of a work of art.

Western Digital announces new Sentinel DS5100 and DS6100 small business NAS devices

Subject: Storage | October 10, 2013 - 09:21 PM |
Tagged: western digital, wdc, WD

Today, Western Digital announced a couple of additions to their small business NAS solutions.

WD Sentinel DS6100 101013.jpg

These two new devices, marked in blue on the below spec comparison chart, are an updated version of the previous Sentinel DX4000 and RX4100 models. The new units feature Xeon processors running Windows Server 2012 R2 Essentials. Unlike previous models, the new units can boot from separate 2.5" HDD's (or SSDs) running single or in a RAID-1 mirrored pair, meaning the system does not have to rely on the primary storage array for OS files. The use of the new Windows Server also enables the use of Storage Spaces in lieu of the on-board RAID solution, should the configuration require it.

These are definitely higher end NAS devices which pack a lot of processing punch. As a result, they are a far cry from an ARM powered home NAS in price as well as in performance. We're following these releases closely, and expect additional releases along these lines from Western Digital in the future. I hope to see an 8 bay (or greater) model materialize as well.

Imagine a device of a similar form factor to the Western Digital My Book, but instead of USB or Thunderbolt connectivity, you had a Gigabit Ethernet connection and a dual core CPU capable of handling large throughputs to your home network. Toss in some back end software and a handfull of remote access apps for various mobile devices, and you have what Western Digital calls the My Cloud:

The concept behind this is to have something similar to DropBox, with some differences. We will be diving further into the My Cloud shortly and will publish a full write-up for your viewing pleasure, but for now it seems to cover every base except for having your shared data available on mobile devices when those devices are offline (with the exception of cached copies, of course).

Introduction

Introduction:

Last July, I went on a bit of a mini-rant about how using a bunch of drives not meant to be in a RAID could potentially lead to loss of the entire array from only a few bad sectors spread across several disks. Western Digital solved this problem by their introduction of the WD Red series. That series capped out at 3TB, and users were pushing for larger storage capacities for their NAS devices. In addition to the need for larger disks came the need for *smaller* disks as well, as there are some manufacturers that wish to create NAS / HTPC type devices that house multiple 2.5" HDD's. One such device is the Drobo Mini - a 4x2.5" device which has not really had a 'proper' NAS storage element available - until now:

130903-053614-9.27.jpg

Today Western Digital has announced a twofold expansion to their Red Series. First is a 4TB capacity in their 3.5" series, and second is a 2.5" iteration of the Red, available in both 750GB and 1TB capacities.

As a recap of what can potentially happen if you have a large RAID with 'normal' consumer grade HDD's (and by consumer grade I mean those without any form of Time Limited Error Recovery, or TLER for short):

  • Array starts off operating as normal, but drive 3 has a bad sector that cropped up a few months back. This has gone unnoticed because the bad sector was part of a rarely accessed file.
  • During operation, drive 1 encounters a new bad sector.
  • Since drive 1 is a consumer drive it goes into a retry loop, repeatedly attempting to read and correct the bad sector.
  • The RAID controller exceeds its timeout threshold waiting on drive 1 and marks it offline.
  • Array is now in degraded status with drive 1 marked as failed.
  • User replaces drive 1. RAID controller initiates rebuild using parity data from the other drives.
  • During rebuild, RAID controller encounters the bad sector on drive 3.
  • Since drive 3 is a consumer drive it goes into a retry loop, repeatedly attempting to read and correct the bad sector.
  • The RAID controller exceeds its timeout threshold waiting on drive 3 and marks it offline.
  • Rebuild fails.
  • Blamo, your data is now (mostly) inaccessible.

I went into much further detail on this back in the intro to the WD 3TB Red piece, but the short of it is that you absolutely should use a HDD intended for RAID when building one, and Western Digital is removing that last excuse for not doing so by introducing a flagship 4TB capacity to the Red Series.
