WD Red drives *do* support TLER...

This morning I received a tweet about WD Red drives not supporting Time Limited Error Recovery. TLER is the feature which allows a RAID comprised of Reds to much more gracefully handle drive failures and/or read errors. It's carried down from enterprise drives like the RE4 and RE4-GP.

I'm posting this quick note here to let the masses know that the Red drives *do* in fact support TLER. It's a primary component of NASware - the NAS aware firmware that drives the Reds. Here's the official reply I received from Western Digital:

WD does enable intelligent error recovery controls, which is not the same as a desktop drive.  WD's exclusive NASware technology is built in each WD Red drive, which reduces the concern with using desktop drives in a RAID environment.
More info on details of NASware can be found here:  http://www.wd.com/en/products/products.aspx?id=810

Western Digital has assured me they are tracking down where the miscommunication occurred.

Introduction:

I'm going to let the cat out of the bag right here and now. Everyone's home RAID is likely an accident waiting to happen. If you're using regular consumer drives in a large array, there are some very simple (and likely) scenarios that can cause it to completely fail. I'm guilty of operating under this same false hope - I have an 8-drive array of 3TB WD Caviar Greens in a RAID-5. For those uninitiated, RAID-5 is where one drive worth of capacity is volunteered for use as parity data, which is distributed amongst all drives in the array. This trick allows for no data loss in the case where a single drive fails. The RAID controller can simply figure out the missing data by running the extra parity through the same formula that created it. This is called redundancy, but I propose that it's not.

Western Digital releases 'Red" series of SOHO NAS hard drives

** Note ** - Full review has been posted HERE!

Today Western Digital launches their Red series of hard drives. These are basically Caviar Greens that are specificially tuned to operate in small RAID configurations - namely home and small business NAS solutions containing up to 5 drives. These drives carry over some of the features present on Western Digital's Enterprise lines while adding a few of their own.

We got samples of the Red in yesterday evening, so instead of going on with conjecture derived from the news post, I'll hit you with the new features and a bit of my initial impressions from our early benching:

  • Extremely quiet operation thanks to a new dynamic balancing mechanism built into the spindle motor hub. The drive essentially re-balances itself on-the-fly as temperatures change, etc.
  • Seeks are equally quiet - quiet enough that a bunch of these doing random access outside of an enclosure would barely be audible from only a few feet away.
  • Great sequential throughput (~150MB/sec at start of disk, ramping down to ~65MB/sec at the end).
  • Random access times in the 20ms range - likely due to the very quiet seeking mechanism.
  • Red Series drives will all be advanced format (i.e. internally addressed by 4k sectors).
  • Reds will all be 1TB/platter, available in 1, 2, and 3TB capacities. This gives similar throughput figures regardless of capacity purchased.
  • 3-year warranty, with a 24/7 support hotline specifically for Red owners.
  • Red drives feature a QR code on the label to assist with any support issues down the road.

I'm not kidding about the quiet operation. The only sound the Red makes is reminiscent of a DVD spinning at low speed, in a sound deadening enclosure. There is no motor whine whatsoever and the head actuator is nearly inaudible. I have to almost lay my head on the drive to tell it is seeking at all.

A full review with all of the gory details will be up later today. For now I leave you with the WD press release after the break, along with this nifty QR to get you more info on the Red Series:

Are Western Digital and Seagate doomed to be marked as bad sectors?

Tagged: Hard Disk, Seagate, western digital, fud, hdd

There are quite a few things in the industry to speculate on, from Microsoft's intimating a 'big new thing' next Monday to AMD and the HSA's plans for the future of the industry, but if you want to go for the big one then it is the hard drive industry you should be following.  The most recent sign that something big is going on would be the change in warranty length on consumer drives from the two remaining players, both of which now offer a 1yr warranty.  That is a vast reduction from previous 3yr and 5yr warranties and while it does not necessarily imply these drives will fail any faster it does mean they offer shorter warranties than their competition, the SSD.  This could convince a lot of people that paying $1/GB for an SSD is not really that bad of a deal and you can only expect that price to fall, especially on larger sized SSDs.

Also consider the fact that there are only two major HDD manufacturers left, Seagate and Western Digital.  This defragmentation of the industry has been going on for quite a while now, resulting in those two manufacturers owning their competitions resources and IP and pretty much being able to determine what the market will provide and at what cost to the consumer.  That has lead to the rather counter-intuitive profits that these two, especially Western Digital, made over the past year.  You would not expect a company which lost its manufacturing capabilities to the Thai floods to see a 230% increase in profit, yet that is exactly what happened from March 2011 to March 2012.  Seagate held their first place spot over the same time period, with higher volume sales contributing to that success with their prices only rising 20% instead of the 40% they threatened during the supposed supply difficulties.  

The HDD market seems to be on its way out, not just because ultraportable devices chose SSDs over HDDs but also because the average consumer has come to the realization that while having a few terabytes of storage is nice for long term storage they really do not need it, especially on a device which does not have long term support.  The Inquirer smells something foul in the air and comments on this topic here.

"Seagate, Western Digital and to a lesser extent Toshiba are starting to see free market economics - or as close as it gets - show their strategy of consolidation and profiteering. With the number of solid state disk (SSD) in the low teens, prices are falling steeply while hard drive makers rely on artificially high prices and shorter warranties to make a quick buck."

Introduction

A few weeks ago I witnessed a technology demo by Western Digital. I arrived expecting to see something storage related, but what I saw was completely different - a new line of routers!

120521-153534-4.8.jpg

The new 'My Net' series of Western Digital routers are intended to cover the mid to high end of the home usage spectrum. Models start with 4 ports of Fast Ethernet and scale all the way up to 7x GigE switching. All models support some form of simultaneous dual band (2.4 and 5 GHz), with a minimum of 2x2 and scaling up to 3x3 configurations (more detail / explanation on that later).

2TB of storage in your pocket

Tagged: western digital, my passport, usb 3.0

Western Digital's line of My Passport portable hard drives have been with us for a while, improving along with the available technology for inexpensive mobile storage.  Unfortunately the term inexpensive is used loosely as the industry is still recovering from the disastrous flooding in Thailand, so the 2TB model is just over $200 on NewEgg.  However, at that price you get a large amount of storage in a 21 x 82 x 111mm (0.82" x 20" x 4.4") device and since it uses USB 3.0 you won't have to wait all day for transfers.  TechARP's testing had it beating almost every device for transfer speed, with only OCZ's 64GB Enyo offering competition on a handful of tests.

"Western Digital has a wide variety of external storage products for both the PC and Mac markets. The external drives are available in both large desktop and smaller portable formats. Under the portable segment alone, Western Digital offers five drive families for the PC, and three drive families for the Mac.

Today, we are going to take a look at their latest portable hard disk drive for the PC market - the 2 TB Western Digital My Passport (USB 3.0)."

Western Digital retains number 2 status

Subject: General Tech | April 30, 2012 - 04:01 PM |
Tagged: western digital, sales

With the horrible flooding in Thailand that destroyed Western Digital's ability to produce hard drives many were concerned about their profits for the beginning of this year.  While they did not surpass Seagate for the number one spot, they have recovered after a poor first quarter.   As you can see in the graph their total sales dropped far more than their net profit, in part thanks to a few weeks of profits from their newly purchased Hitachi GST component.  Read all the big numbers at The Register.

Introduction

It's been a long while since we've looked at a hard drive, and how fitting that it be a new model of the Western Digital VelociRaptor! Western Digital appears to be on a somewhat fixed 2-year cycle with these, as out 600GB VelociRaptor Review went up two Aprils ago, and the 300GB two years prior to that. Well then, let's take a look at this new model!

The SSD market gets passed a TRIM command

Hitachi Global Storage Technologies, which was the result of the merger of Hitachi and IBM's HDD businesses, is likely being purchased by Western Digital tomorrow for about $4.3 billion.  This makes sense as WD has been using Hitachi GST as a sales partner when providing  EMC with high end flash disks.  This deal comes on the heels of a major sell, the SSD400S flash disk which uses Intel's 34nm SLC NAND and the SSD400S-B which utilizes the new 25nm NAND developed by Intel.  Check out the specifications of the flash drives as well as the new SSD company over at The Register.

"WD is buying Hitachi GST and the acquisition is expected to be formally announced tomorrow with a condition of two years of independence for Hitachi GST - imposed by a Chinese anti-competition regulator. EMC has certified Hitachi GST's SSD400S flash disks for use in its VNX mid-range unified storage arrays, including the all-flash VNX5500-F, so WD will effectively fulfil this deal once the acquisition is announced."
