Tagged: Seagate, hdd, BarraCuda Pro, 14tb

Inside the Barracuda Pro are eight platters each 1.75 TB in size and comes with a nice addition to the warranty, if the drive dies before two years have expired you can ship the drive to Seagate and they will attempt to recover your data for free.  The Guru of 3D's testing showed the accuracy of the 250MB/sec rating, as expected from a modern SATA HDD. The total warranty is five years and the drive is rated for 24/7 use with a 300TB/yr rating so there are certainly plenty of usages for the drive.

"It's here! We review the Megalodon among the HDDs, the Barracuda Pro 14TB from Seagate is unleashed today, that's a 14.000GB HDD folks! This, by far, is the biggest single consumer unit storage device to date. It might not offer SSD performance, but it certainly isn't slow. It's the year 2018, it's big but with these massive HDD platters, will it be fast enough?"

Western Digital Launches Ultrastar DC HC530 - TDMR 14TB HDD

Subject: Storage | April 18, 2018 - 05:39 PM |
Tagged: wdc, WD, ultrastar, sata, SAS, HelioSeal, hdd, DC HC530, 14tb

Following up on the prior release of a 14TB SMR (shingled magnetic recording) HDD, WD has launched a PMR (parallel magnetic recording)version of the same - the Ultrastar DC HC530:

UltrastarDC-HC530.jpg

While the new model does not yet incorporate MAMR, it does couple PMR with TDMR (two-dimensional magnetic recording), which gives a slight boost to platter density, reaching over 900 Gbit/sq. inch. The DC HC530 naming is a departure from the previous HGST Ultrastar line products, which were labeled as 'He8', 'He10', etc. High-level specs are as follows:

  • Rotational speed: 7200 RPM
  • Data buffer: 512MB
  • Seek time (typ): 7.5 ms
  • Sequential transfer rate: 267 MB/s (start of disk)
  • Available sector sizes: 512e (advanced format emulation), 4Kn (4KB sectors)
  • Warranty: 5 years

The SAS models offer double the interface throughput (12Gbps) and some additional custom sector sizes but require higher operating power to drive that faster interface. While track linear density is high enough (at least at the start of the disk) to saturate a SATA 3Gbit link, SATA 6Gbit and SAS 12Gbit links will still see a cache-hit benefit from the drives' relatively large 512MB data buffer.

WD's press release appears after the break, and more information is available on the Ultrastar DC HC530 product page.

Toshiba Refreshes HDD Branding, Intros Surveillance and Video Streaming Models

Tagged: x300, V300, toshiba, s300, P300, N300, L200, hdd

Today (well, tonight) Toshiba changed up their HDD branding to make things a bit easier to grasp for the consumer, as well as adding surveillance and video streaming models to their lineup:

2018-04-16-21-48-50.png

Toshiba chose to go with a round of colors, but these are notably different than what you have previously seen from WD. Typical desktop and mobile drives now carry a red label, with their performance desktop model going grey. NAS HDDs are yellow, and the two new items are blue and green. Let's take a closer look at these new additions:

2018-04-16-21-49-12.png

The blue 'Video Stream V300' model comes in up to a 3TB capacity and is firmware optimized for handling multiple (4) simultaneous video streams without thrashing the heads constantly seeking between tracks. This is a low RPM drive and is meant more for use in DVRs. Max capacity comes in only 3TB, but this is a very low cost and low power drive. Note the 'annual workload rating' of 72TB per year. More on that later.

2018-04-16-21-49-02.png

The green 'Surveillance S300' model is meant for significantly more demanding workloads upwards of 64 simultaneous HD video camera streams. These are meant for incorporation into large arrays and come with the necessary RV (accelerometer) sensors to help keep the heads on track while the drive is subjected to harsher vibrations seen in large server chassis. These come in up to 10TB with a workload rating of 150TB per year.

2018-04-16-21-49-42.png

Above are the general specs across the entire lineup, and below are the prices for the two new models:

  • V300 Video Streaming
    • 1TB - V300 Video Streaming - $49.99
    • 2TB - V300 Video Streaming - $69.99
    • 3TB - V300 Video Streaming - $89.99
  • S300 Surveillance
    • 4TB - S300 Surveillance - $119.99
    • 5TB – S300 Surveillance - $149.99
    • 6TB - S300 Surveillance - $189.99
    • 8TB - S300 Surveillance - $249.99
    • 10TB - S300 Surveillance - $349.99

Those prices look very competitive, but that 'annual workload rating' troubles me a bit, especially for the S300. That model is meant for use in an array, which must be initialized (eating one full drive write), possibly migrated (eating another full drive capacity worth of access), and with some RAID controllers, periodically scrubbing the data to verify integrity. A large array of 10TB HDDs with periodic array scrubbing/integrity checking scheduled every 2-3 weeks will technically run these parts past their rated workload. Backing off to monthly checks will get you just under the limit, provided your actual video workload does not push you over. Just something to consider when specing out a surveillance unit build.

Press blast for these new models appears after the break.

Data packrats strike Gold with WD

Tagged: western digital, wd gold, hdd, 12TB

The 12TB WD Gold is not quite as impressive as Toshiba's 14TB drive but it should be more affordable for consumers with specific needs or for SMBs.  Like the Toshiba drive it uses PMR as opposed to a shingled design, which again helps keep the drive's price under $600 and in the price range Ryan would like to see SSDs reach.  The drive is rated at 2.5 million hours MTBF and as far as performance, Kitguru saw 245.58MB/s for writes and 237.01MB/s reads.  This is not a drive for most, but for those with huge amounts of data who need to be able to move it frequently and at decent speeds, this review is worth looking at.

Slim your bits with spin class and crossfit Crossover

Subject: General Tech | December 7, 2017 - 03:30 PM |
Tagged: spin crossover, hdd

Storage density is running into physical size limitations, as we seek to find ways to store a bit in a smaller area.  Currently a bit on a HDD takes up an area of 10x10nm, depending on the technology used, which may seem tiny but is preventing higher density disks from being developed.  A team of researchers have come up with a new technique which creates stable magnetic spin crossover molecules that can decrease the area of a bit to 1nm2, as well as being able to store up to three states.  There are some major challenges, such as how to mate the molecule to a platter but the research is very interesting.  Drop by EE Times for more information.

"The use of spin crossover molecules as the smallest storage unit would make it possible to further increase the storage density of data carriers. The challenge is to attach these molecules to surfaces without destroying their storage capacity. A research team from the Christian-Albrechts-University of Kiel (CAU) has now succeeded in doing so."

Want another reason to dump that HDD? It can be used as a microphone

Subject: General Tech | October 13, 2017 - 01:01 PM |
Tagged: security, paranoia, microphone, hdd, hack

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 Launches 10TB Red and Red Pro

Subject: Storage | May 17, 2017 - 09:57 PM |
Tagged: western digital, wdc, WD, Red Pro, red, NAS, helium, HelioSeal, hdd, Hard Drive, 10TB

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.

sshot-54.png

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.

Need a huge amount of reliable storage? 10TB of enterprise storage from Seagate

Subject: Storage | March 21, 2017 - 03:07 PM |
Tagged: Seagate, 10TB, enterprise, hdd

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.

WD and HGST Refresh Enterprise SSDs to Include 8TB, Push HDDs to 12TB and Beyond

Since their acquisition of SanDisk and recent wrapping up of a long-time integration with HGST's Helium tech, Western Digital took the lid off of a round of product updates this morning.

wd-9-.png

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.

wd-11-.png

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.

wd-16-.png

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.

wd-14-.png

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.

UltrastarHe12-SN200-SS200-Press-300dpi.jpg

Not bad HDD progress considering we were just discussing 10TB SMR this time last year. We'll be confirming the performance of these as samples arrive for testing.
