Some of you may remember the days when it was inadvisable to yell at a HDD array, the latency issue has been mostly overcome with the advances in technology over the last decade. That does not mean it is completely gone, as the read head in a HDD cannot read from a disk that is oscillating due to external input such as sound, and those tiny delays are how this researcher was able to use the HDD as a low quality microphone. He also found a tone which created even more latency than in that video; enough to have a system drop the disk as bad. There are links to the research over at Slashdot, including the new improved way to verbally abuse your storage devices.
"It's not accurate yet to pick up conversations," Ortega told Bleeping Computer in a private conversation. "However, there is research that can recover voice data from very low-quality signals using pattern recognition. I didn't have time to replicate the pattern-recognition portion of that research into mine. However, it's certainly applicable."

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.
Press blast appears after the break.

The Seagate Barracuda Pro 10TB Enterprise HDD won't give you the fastest access to your data, but if you have a large amount of storage in a reliable format it is worth looking at this review. The MSRP of $444.45USD is much lower than you would pay for 10TB of SSD storage, though you might be able to set up several smaller disks in a Drobo or similar device for a similar price. The MTBF is 2.5 million hours, the endurance rating is 550TB per year and there is a 5 year warranty so even with heavy usage you should be able to depend on this drive for quite a long time. You can drop by NikKTech to see how it performs.
"The Seagate Barracuda Pro 10TB hard disk drive offers good endurance levels with great performance and an even greater capacity. The Enterprise Capacity 3.5 V6 10TB model again by Seagate boosts even higher performance and endurance numbers without asking more from your wallet."

First up is a second generation of HGST-branded SSD products - the Ultrastar SN200. These enterprise SSDs boast impressive specs, pushing random reads beyond 1 million IOPS, coming in 8TB capacity, and if you opt for the HHHL PCIe 3.0 x8 SN260, 6.2GB/s maximum throughput.
Moving into SAS SSDs, the SS200 uses a 12Gbit link to achieve 1.8 GB/s and 250,000 random read IOPS. Write specs dip to 37,000 random as this is a 1 DWPD endurance class product. These are also available in up to 8TB capacities.
Last but certainly not least are preliminary specs for the He12, which boast particularly impressive low QD random write performance and a notable bump in Watts/TB despite the addition of an eighth platter to achieve the 12TB capacity. Note that this is not an archive class product and is meant for continuous random access.
There is also a 14TB model in the lineup, but that is an archive class model that is essentially the He12 with Shingled Magnetic Recording enabled.

Introduction and Packaging
The Drobo 5D launched a few years ago and continues to be a pricey solution, running close to $600. This was due to added complexity with its mSATA hot data cache and other features that drove the price higher than some potential buyers were happy with. Sure the cache was nice, but many photographers and videographers edit their content on a faster internal SSD and only shift their media to their external storage in bulk sequential file copies. These users don’t necessarily need a caching tier built into their mass storage device - as they just want good straight-line speed to offload their data as fast as possible.
With new management and a renewed purpose with a focus on getting lower cost yet performant products out there, Drobo relaunched their base 4-bay product in a third-generation form. We tested that unit back in December of 2014, and its performance was outstanding for a unit that typically runs in the mid-$200 price range. The price and performance were great, but things were a bit tight when trying to use Dual Disk Redundancy while limited to only four installed drives. A fifth bay would have certainly been handy, as would USB-C connectivity, which brings me to the subject of today’s review:
I present to you the Drobo 5C. Essentially a 5-bay replacement to the 4-bay 3rd gen Drobo. This will become the new base model Drobo, meaning there will no longer be any 4-bay models in Drobo's product lineup:

We looked at the third-gen 4-bay Drobo over a year back, and while the performance and price were great, it was held back by its limited number of drive bays. Drobo fixed that today:
The new Drobo 5C is basically an evolution of the 4-bay model. Performance is similar, which justifies the choice to stick with USB 3.0 (5 Gbit), but we now have a Type-C port on the Drobo side (a Type-C to Type-A cable is included to cover most potential users). The added bay helps users increase potential capacity or alternatively select BeyondRAID's Dual Drive Redundancy mode without as much of an ultimate capacity hit compared to its 4-bay predecessor.
The Drobo 5C supersedes the old 4-bay unit in their lineup.
The new Drobo 5C is available today for $349, with drive package deals offered direct from Drobo. Drobo is also offering a limited-time $50 discount to 2nd and 3rd gen 4-bay Drobo owners (valid until 11 Oct 2016). I have confirmed here that a disk pack from a 4-bay model can be moved directly to the new 5-bay model with no issue.
We have a full review of the Drobo 5C coming, but we have a few questions out to them that need answering before our article goes live.
Introduction and Specifications
Barracuda is a name we have not heard in a good while from Seagate. Last seen on their 3TB desktop drive, it appears they thought it was time for a comeback. The company is revamping their product lines, along with launching a full round of 10TB Helium-filled offerings that cover just about anything you might need:
Starting from the center, IronWolf is their NAS drive, optimized for arrays as large as 8 disks. To the right is their surveillance drive offering, the SkyHawk. These are essentially NAS units with custom firmware optimized for multiple stream recording. Not mentioned above is the FireCuda, which is a rebrand of their Desktop SSHD. Those are not He-filled (yet) as their max capacity is not high enough to warrant it. We will be looking at those first two models in future pieces, but the subject of today’s review is the BarraCuda line. The base 3.5” BarraCuda line only goes to 4TB, but the BarraCuda Pro expands upon those capacities, including 6TB, 8TB, and 10TB models. The subject of today’s review is the 10TB BarraCuda Pro.
Introduction, Packaging, and Internals
Being a bit of a storage nut, I have run into my share of failed and/or corrupted hard drives over the years. I have therefore used many different data recovery tools to try to get that data back when needed. Thankfully, I now employ a backup strategy that should minimize the need for such a tool, but there will always be instances of fresh data on a drive that went down before a recent backup took place or a neighbor or friend that did not have a backup.
I’ve got a few data recovery pieces in the cooker, but this one will be focusing on ‘physical data recovery’ from drives with physically damaged or degraded sectors and/or heads. I’m not talking about so-called ‘logical data recovery’, where the drive is physically fine but has suffered some corruption that makes the data inaccessible by normal means (undelete programs also fall into this category). There are plenty of ‘hard drive recovery’ apps out there, and most if not all of them claim seemingly miraculous results on your physically failing hard drive. While there are absolutely success stories out there (most plastered all over testimonial pages at those respective sites), one must take those with an appropriate grain of salt. Someone who just got their data back with a <$100 program is going to be very vocal about it, while those who had their drive permanently fail during the process are likely to go cry quietly in a corner while saving up for a clean-room capable service to repair their drive and attempt to get their stuff back. I'll focus more on the exact issues with using software tools for hardware problems later in this article, but for now, surely there has to be some way to attempt these first few steps of data recovery without resorting to software tools that can potentially cause more damage?
Well now there is. Enter the RapidSpar, made by DeepSpar, who hope this little box can bridge the gap between dedicated data recovery operations and home users risking software-based hardware recoveries. DeepSpar is best known for making advanced tools used by big data recovery operations, so they know a thing or two about this stuff. I could go on and on here, but I’m going to save that for after the intro page. For now let’s get into what comes in the box.
Note: In this video, I read the MFT prior to performing RapidNebula Analysis. It's optimal to reverse those steps. More on that later in this article.

Tagged: usb 3.0, Thunderbolt 2, raid, hdd, drobo, DAS, BeyondRAID, 5Dt, 5D
Today Drobo updated their 5D, shifting to Thunderbolt 2, an included mSATA caching SSD, and faster internals:
The new 5Dt (t for Turbo Edition) builds on the strengths of the 5D, which launched three years ago. The distinguishing features remain the same, as this is still a 5-bay model with USB 3.0, but the processor has been upgraded, as well as the USB 3.0 chipset, which was a bit finicky with some earlier implementations of the technology.
The changes present themselves at the rear, as we now have a pair of Thunderbolt 2 (20 Gb/s) ports which support display pass-through (up to 4k). Rates speeds climb to 540 MB/s read and 250 MB/s write when using HDDs. SSDs bump those figures up to 545 / 285 MB/s, respectively.
Another feature that has remained was their Hot Data Cache technology, but while the mSATA part was optional on the 5D, a 128GB unit comes standard and pre-installed on the 5Dt.
The Drobo 5Dt is available today starting at $899. That price is a premium over the 5D, but the increased performance specs, included SSD, and Thunderbolt connectivity come at a price.
The current (updated) Drobo product lineup.
Full press blast after the break.
Introduction, Specifications, and Packaging
Western Digital launched their My Passport Wireless nearly two years ago. It was a nifty device that could back up or offload SD cards without the need for a laptop, making it ideal for photographers in the field. I came away from that review wondering just how much more you could pack into a device like that, and today I get to find out:
Not to be confused with the My Passport Pro (a TB-connected portable RAID storage device), the My Passport Wireless Pro is meant for on-the-go photographers who seek to back up their media while in the field but also lighten their backpacks. The concept is simple - have a small device capable of offloading (or backing up) SD cards without having to lug along your laptop and a portable hard drive to do so. Add in a wireless hotspot with WAN pass-through along with mobile apps to access the media and you can almost get away without bringing a laptop at all. Oh, and did I mention this one can also import photos and videos from your smartphone while charging it via USB?
- Capacity: 2TB and 3TB
- Battery: 6,400 mAH / 24WH
- UHS-I SD Card Reader
- USB 3.0 (upstream) port for data and charging
- USB 2.0 (downstream) port for importing and charging smartphones
- 802.11AC + N dual band (2.4 / 5 GHz) WiFi
- 2.4A Travel Charge Adapter (included)
- Plex Media Server capable
- Available 'My Cloud' mobile apps
No surprises here. 2.4W power adapter is included this time around, which is a nice touch.
