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.

 

Seagate lets you guess the SSD manufacturer it wants to buy

CFO of Seagate, Pat O’Malley, is looking to purchase a solid state drive manufacturer but will not confirm rumors that OCZ is who they have in mind. They then acknowledge that there is only one company who would make sense for them to acquire.

It is kind-of like you are trying to be stealthy with your interest in a girl in your classes – but it is all throughout the gossip circles. Also, you say you like tall blonde women and there is only two in your program; the other is Intel, nothing more needs to be said.

Ya CZ.

Reuters arranged a discussion with Pat O’Malley, the Chief financial officer (CFO) of Seagate. During the interview, O’Malley announced that Seagate would be interested in purchasing an SSD manufacturer with a strong presence in the enterprise market. O’Malley was further questioned about rumors of Seagate purchasing OCZ. The response was about as thinly veiled as a non-answer could be before it would be considered a confirmation.

“We look at all technology product providers but what I would say is that on the enterprise SSDs, there’s probably only one of them that really makes and significant money.”

And they certainly will make significant money now – as investors binge a little to own a few extra shares.

“We don’t do any comments on official policy on M&A ((Mergers and Acquisitions)) until it’s done.”

Directly.

Update: As commentors and coworkers have mentioned -- it would not be too far fetched for Seagate to be talking about companies such as FusionIO. Still -- OCZ feels most likely to me.

A little DIY hard drive unbricking

While this trick will not work on all bricked HDDs, if you have a Seagate 7200.11 HDD that is failing because it is convinced it is always in a busy state then you should check out this story on Hack a Day.  While the initial step of detaching the circuit board and blocking some connections with piece of cardstock can be handled with easy, it will take some expertise to use an Arduino or serial-TTL converter to issue commands to the HDD controller.  It is a good thing that there is a tutorial to walk you through the steps to unbrick your HDD, besides in the worst case scenario your HDD will still be a brick so it is worth a shot.

"Hard drive firmware is about the last place you want to find a bug. But that turned out to be the problem with the Seagate HDD which he was using in a RAID array. It stopped working completely, and he later found out the firmware has a bug that makes the drive think it’s permanently in a busy state. There’s a firmware upgrade available, but you have to apply it before the problem shows its face, otherwise you’re out of luck. Some searching led him to a hardware fix for the problem."

Drobo 5D and Drobo Mini with Thunderbolt Available for Pre-order, Final Pricing Announced

Subject: Storage | July 25, 2012 - 01:58 PM |
Tagged: thunderbolt, redundant storage, drobo mini, drobo 5d, drobo

We covered the new Thunderbolt-equipped Drobo units last month, and they are looking like promising additions to the company’s lineup. Both Drobo units were slated for a July release, and they are right on track. You can now pre-order the Drobo 5D and Drobo Mini from a number of retailers including Amazon, NCIX, B&H Photo, and Tiger Direct among others.

For the uninitiated, the Drobo 5D is a five bay Drobo S with upgrades. It features USB 3.0 and Thunderbolt interfaces as well as an mSATA SSD to improve performance. Like the predecessor, it will accept standard 3.5-inch desktop drives. You can pre-order it now for $849.

The Drobo Mini on the other hand forgoes desktop drives to achieve a much smaller form-factor. It will accept up to four 2.5-inch laptop hard drives (or SSDs if you want crazy speeds). The Drobo Mini is further able to connect to your computer using either USB 3.0 or Thunderbolt. Like the Drobo 5D, it has an integrated mSATA port (not included). You can pre-order this little redundant storage system for $649.

You can find more information about the new Drobo products on the company’s website. The full press release is available here..

OCZ Announces New Indilinx Barefoot 3 Controller

Subject: Storage | July 18, 2012 - 07:19 PM |
Tagged: ssd, aragon, Indilinx, barefoot 3, ssd controller

During a recent earnings call, OCZ CEO Ryan Petersen made an interesting announcement relating to the company’s solid state drives (SSD). Specifically, it concerns OCZ’s subsidiary company Indilinx which was purchased in 2011 for $32 million of OCZ common stock. According to a transcript provided by SeekingAlpha, OCZ is working on a new SSD based on the company’s Barefoot 3 controller. That controller is especially intriguing because it is reportedly being internally-developed and will use a new Aragon SSD processor which is a controller chip running at 400 Mhz with an optimized and custom RISC instruction set.

The Aragon core is further a 32-bit chip based on TSMC’s 65nm process node. It is using certain IP that is being licensed from an as-yet-unnamed third party. Allegedly, it is able to execute most instructions and branches in a single clock cycle. Bearing in mind that this is an announcement to shareholders, OCZ has stated the following about the new controller:

“When implemented in SSD controller, this gives the core a much higher performance than when using an off-the-shelf embedded safety field. And this design opens a world of new possibilities for game changing SSD solutions as it supports unprecedented levels of processing power.”

Beyond that we do not know what kind of performance to expect from the drives, but we should not have to wait too long to find out. OCZ should begin sampling the drives sometime between August and September of this year and are hoping to make them available for purchase by the holiday shopping season in Q4 2012.

It will be interesting to see where this new OCZ/Indilinx controller stands in relation to the other controller makers. Here’s hoping that it can give SandForce and Intel a run for their money and give us even more competition to drive down SSD prices for consumers!

Tagged: super talent, ST1, ST2, usb 3.0

If you need fast and portable storage then a USB 3.0 flash drive is the way to go as there is a large difference in speed when you compare it to the previous USB 2.0 standard.  Super Talent currently offers two versions the the ST1 which uses ToggleMode DDR and has and advertised speed of 90MB/s read and 16MB/s write speeds as well as the ST2 which has dual channel MLC flash and 67MB/s read and 24MB/s write speeds.  The other difference between the two models is the capacity, with the ST1 going from 8GB to 16GB and the ST2 available in sizes up to 32GB.  Check out the real world results at Legit Reviews.

LR_supertalent_top.jpg

"The two drives we have to review today are the Super Talent Express 3.0 ST1 4GB and the Express 3.0 ST2 8GB. These two are the smallest capacity drives of their respective lineups. The ST1 ranges from 4GB-16GB, and the ST2 ranges from 8GB-32GB. The ST1 uses Super Talent’s ToggleMode DDR (double data rate) flash which claims 90MB/s read and 16MB/s write speeds. The ST2, however, uses a dual channel MLC flash, claiming 67MB/s read and 24MB/s write speeds..."

Tagged: ssd, intel 330, Intel

Good news SSD fans Intel has not only extended their SandForce SF2281 based 330 line, they have also dropped prices across the board.  The new 240GB Intel SSD 330 should be on sale for $194, dropping comfortably below the $1/GB mark.  Intel has reduced the costs to their resellers as well, by up to 38 percent on 520 Series, 10% - 18% for the 320 Series and 27% - 34% on the 330 Series.  These price changes may not directly translate into the same savings for those purchasing from major retailers but it will certainly have some impact.  For instance, right now the Intel 330 180GB model will cost you $160 while the 120GB 320 model remains $170.  The 520 series also remains above $1/GB but with this announcement from Intel you should really keep a close eye on PC Perspective and your favourite retailers for price changes.

MSI Possibly Working on SandForce SF-2000-series SSD

Tagged: storage, ssd, SF2000, sandforce, msi

The solid state market is heating up as spindle-based drives continue to sell at much higher prices than last year and NAND flash is getting cheaper. The latest entrant may be motherboard and laptop vendor MSI, if a recent addition to SandForce’s SSD partner list holds true.

msi_ssd.jpg

Unfortunately, we do not have any further details so it’s hard to say what sort of drive this will be other than it will use solid state NAND flash. Being a 2000-series SandForce controller is promising for performance, however. Stay tuned for more details as they develop. I’m excited to see what MSI can bring to the SSD table, and here’s hoping that they break a cost/GB record (I can dream heh). For now though, we will have to suffice with the currently available SSD options, which you can check out on our SSD Decoder at pcper.com/ssd. What do you think about the prospect of an MSI SSD?

Introduction and Internals

120711-023332-8.59-.jpg

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.
