In a recent and more rigorous experiment, a group of researchers from the University of Illinois Urbana-Champaign, University of Michigan and Google, dropped nearly 300 USB thumb drives around six campus locations and found that at least 45 percent of them were plugged into a computer and perused by the person who found them.While modern Windows and Mac systems no longer run programs on a USB stick by default, other attacks, such as BadUSB, can make a USB drive appear to be something else, such as keyboard, and then use that access to take malicious actions.When the company finds untrusted USB drives, it can test them, said Chris Novak, a director with the firm s RISK team, a computer investigations group.We often do executive protection, where, when executives go overseas or to a big conference, we give them temporary equipment, and if something happens, we get it back.Playing the movie trailer on the drive installed malware on the victim s computer, enabling the attacker to steal an unreleased movie.The fact that users plug such storage devices into corporate computers is a nightmare for IT security professionals, to the degree that they sometimes—and somewhat controversially—block USB ports on highly sensitive computers by gluing them closed with epoxy.
In an ideal world, computers would only have one type of data storage, but thanks to the laws of physics and businesses, we have two main types three if you count CPU L caches .Previous PCM implementations only used 1 bit per cell, basically equivalent to storing either 0 or 1 2 values ."Someday" being the operative word here.As no actual commercially available implementation has been launched yet, we can't really speculate on how viable PCM will be as a replacement for both DRAM and flash.As mentioned, it is a topic of interest in the wider computing industry, including other companies.Suffice it to say, whoever is able to come out with a wallet-friendly and reliable solution first could very well end up in the annals of computing history as the pioneers of the new age of computer memory.
The breakthrough involves phase-change memory PCM which IBM has successfully achieved storing three bits of data per cell for the first time, compared to previous demonstrations of storing one bit per cell.PCM is much more durable than flash – it can last something like 10 million write cycles compared to the average flash USB stick which endures around 3,000 write cycles – and it's way faster, coming closer to DRAM performance, but with one big difference: it doesn't lose data when switched off like DRAM.Significant cost reductionDr Haris Pozidis, manager of non-volatile memory research at IBM Research, commented: "Phase change memory is the first instantiation of a universal memory with properties of both DRAM and flash, thus answering one of the grand challenges of our industry.The new memory tech could have implications across a range of uses, including providing blazingly quick storage for cloud and IoT applications, and boosting performance of the likes of machine learning.Businesses could see entire databases stored in PCM enabling ultra-fast querying, and of course this will also make a major difference to smartphones.IBM envisions hybrid applications with PCM running alongside traditional flash storage in a phone, but with the OS stored in the PCM so when you switch your phone on, it loads almost immediately and you're staring at your home screen before you've had time to bat an eyelid.
In PCM cell, '0' is programmed to be written in the amorphous phase or a '1' in the crystalline phase, or vice versa while low voltage is applied to read the bits back as in re-writable Blue-ray Discs.For storing 3 bits per cell, the scientists have developed a set of drift-immune cell-state metrics and drift-tolerant coding and detection schemes.IBM Research - Zurich manager of non-volatile memory research and one of the authors of the paper Dr. Haris Pozidis said: "Phase change memory is the first instantiation of a universal memory with properties of both DRAM and flash, thus answering one of the grand challenges of our industry."Reaching 3 bits per cell is a significant milestone because at this density the cost of PCM will be significantly less than DRAM and closer to flash."With the technology, scientists are expecting that a mobile phone's operating system could be stored in PCM, which will help it launch in a few seconds.The technology could also be used in enterprise environments, as the entire databases could be stored in PCM, allowing faster query processing for time-critical online applications, such as financial transactions.
Big Blue researchers demonstrate reliable phase-change memory PCM Scientists at IBM Research said they have for the first time reliably stored 3 bits of data per cell and retained the information at elevated temperatures , a technical advance that makes phase-change memory PCM an alternative to flash storage.Long Time ComingIBM Stand MWC 2016IBM scientists in Zurich first introduced PCM technology way back in 2011, when they presented a whitepaper at the 3rd IEEE International Memory Workshop in Monterey, California.Researchers believe this means it could be used in either standalone PCM, as well as hybrid applications that combines PCM and flash storage together, with PCM acting as an extremely fast cache.This is how re-writable Blue-ray Discs store videos, said IBM Phase change memory is the first instantiation of a universal memory with properties of both DRAM and flash, thus answering one of the grand challenges of our industry, said Dr. Haris Pozidis, an author of the paper and the manager of non-volatile memory research at IBM Research – Zurich.Reaching 3 bits per cell is a significant milestone because at this density the cost of PCM will be significantly less than DRAM and closer to flash.The chip consists of a 2 2 Mcell array with a 4- bank interleaved architecture.
Better-than-binary multi-level memoryMemory could be getting an upgrade beyond the two states used in binary, as researchers have designed a magnetic element with six stable magnetic states, according to a paper published in Applied Physics Letters.They consume less power, allow memory to be written and read at a quicker pace, and last longer."Furthermore, since MRAM is different in its nature from flash, there is no reason that it should suffer from the drawbacks of multi-level-cell flash memory."This technique, known as spin-orbit torque switching, shows that more memory can be packed over a tighter space.Researchers believe that even more magnetic states can be created by adding more layers of magnetic film – crossing four ellipses could give eight magnetic states.The researchers said they would like to "progress towards fabricating a prototype" that would help them "convince the magnetic memory industry to make a shift towards multi-level magnetic memory."
The first day of Google's I/O conference might have been heavier on software than hardware, but that doesn't mean gadget-lovers will be left out in the cold.Caught up in the deluge of other news was the announcement of new partners coming to Android TV - particularly Chinese phone manufacturer Xiaomi, which is developing its own set-top box for the platform.The Mi Box packs a lot of power inside its small casing, with 8GB of flash memory, 2GB of DDR3 RAM, a quad-core Cortex-A53 2.0GHz processor, and output of up to 60 frames per second in glorious 4K resolution.The Mi Box also features voice commands, Google Cast support, and comes with a Bluetooth-enabled wireless remote similar in design to the Nvidia Shield - another 4K Android TV device currently on the market.Just like the Shield, the Mi Box will also have a special gaming controller for those who wish to play Android's selection of games with two hands instead of one.While pricing and release details are still unknown, the device is planning on coming to the US - a first for Xiaomi's line of set-tops.
Google Home is likely to stand out as the most memorable new piece of hardware revealed at I/O 2016 but away from the spotlight, Google added some new televisions and set-top boxes to its Android TV lineup.The most notable of the bunch is a new set-top box from Chinese electronics maker Xiaomi called the Mi Box.The Mi Box is powered by a quad-core Cortex-A53 processor clocked at 2.0GHz, Mali 450 graphics running at 750MHz and 2GB of RAM.There s also 8GB of eMMC flash memory on board, dual-band 802.11 a/b/g/n/ac Wi-Fi and Bluetooth 4.0 / 3.0.A Bluetooth-powered voice remote accepts two AAA batteries.There s even an optional Bluetooth gamepad called the Mi Game ControllerThe product page and announcement on Google s Android blog doesn t mention a price or release date but we do know the set-top box is headed to the US.
Dell has updated its Storage Centre Operating System 7 SCOS 7 in its latest attempt to grab a piece of the expanding flash-based storage architecture market.In addition, the SCOS 7 has been designed to enhance support for virtualisation and cloud strategies, and help increase portfolio-level investment protection."One of the core capabilities of the SC architecture over the last few years it has been to mix different kinds of drives together, so we can blend the characteristics of performance, capacity and cost.According to the company, the SCOS 7 also elevates storage management control as a future-proofed capability.With Dell's new Live Migrate feature, storage administrators can now move volumes quickly and seamlessly between arrays, optimising and re-balancing the environment without interrupting workloads and without purchasing additional virtualisation hardware or software.Lastly, Dell also released the Dell Storage Manager DSM software, to help unify the storage ecosystem in the data centre.

Dell s enterprise storage operating system follows introduction of a network OS earlier this yearDell continues to round out its enterprise offerings with the official release of Storage Center Operating System 7 SCOS 7 .Dell claims that SCOS 7 will help lower acquisition costs across flash and hybrid arrays; help lower lifecycle costs elevated simplified management; and enhance support for virtualisation and cloud strategies.This allows sStorage administrators to move volumes quickly and seamlessly between arrays, optimising and re-balancing the environment without interrupting workloads and without purchasing additional virtualisation hardware or software.Dell of course is in the middle of a hugely expensive purchase of storage giant EMC, that will see the PC maker take on about $59.1bn £41bn in debt as a result of the acquisition.Last month EMC revealed its first quarter results that made for uncomfortable reading for new owner Michael Dell.Whilst it managed a modest profit increase, sales were down to $5.5bn £3.8bn from $5.6bn £3.9bn a year earlier.
This IBM TLC PCM occupies the same general space in the memory-storage hierarchy, defined by latency, as Intel/Micron's 3D Point.We can slot this PCM into a latency table we used for XPoint:Unlike its presentation of XPoint, IBM has provided some endurance numbers, saying it lasts for at least 1 million write cycles, which is far better than the 3,000 it quotes for TLC flash.The substance stores bits as differing resistance levels, with eight of them needed for the 3-bit values it stores.It has overcome a resistance drift problem by devising algorithms and signal processing techniques that it enable it to follow the resistance drift, as it were, and still read data.All-in-all it is a convincing demonstration of a storage-class memory technology that could seemingly be productised - except that IBM has no chip manufacturing capability for PCM and no manufacturing partner.Both it and Toshiba have looked into STT-RAM but that doesn't seem promising.
Promo The traditional hard disk array market is declining but the flash storage market is recording huge growth, with All Flash Arrays AFAs sales growing over 75 per cent annually and hybrid flash systems seven per cent year-on-year, according to IDC.This shift is affecting buying decisions in all kinds of businesses with the full impact yet to be realised.FLASH FORWARD is a new one-day conference and expo which intends to plug this information gap.Doors open on 14 June 2016 at Kensington Close Hotel, London and entrance is free to IT professionals in the private and public sector using promo code FFLonPCM , and £50 to members of channel companies.Go here to register for FLASH FORWARD.FLASH FORWARD has four strands:Comparative deployment scenarios for flash and SSD technologies – chaired by Carla Arend, Program Director, European Software, IDC EuropeWhere and when to deploy flash and SSD in both SME and enterprise environments – chaired by Randy Kerns, Senior Strategist, Evaluator GroupThe impact of flash and SSD on application performance/deployment – chaired by Chris Evans, co-founder, Langton blue, and founding blogger, Architecting.ITFuture directions and impacts on datacentres and application time to market – chaired by Chris Mellor, Storage Editor, The RegisterCheck out the complete agenda for FLASH FORWARD.
Sure, we'd find its capabilities pretty limited in 2016, but we'll never not be able to love the Great Unbreakable.In fact the lack of these features is one of the reasons I picked Android over iOS in the past.As a mobile gamer the depth and breadth of titles is fantastic – Limbo, for example is a great little game that you can t get anywhere else.Cameras have become so important on mobiles that there are now some, like the Nokia Lumia 1020 and Samsung Galaxy Zoom, which are more camera than phone.It all depends on your storage needs, but if you don t carry a load of movies or music with you 16GB of which 13.6GB is usable should be adequate, but for many the 32GB model will be optimal and I haven t managed to fill 32GB yet.No pairing is required, each device just needs to be in range.
Azure Premium Storage users can now replicate their workloads onto SSDsMicrosoft is offering some Azure Site Recovery customers the option of using flash storage, rather than traditional hard drives for their backup services.Azure Site Recovery is Microsoft s flagship backup service, and now users of Microsoft s Azure Premium Storage will get access to SSDs, a move the company claims will boost the speed of cloud applications and their backup counterparts in storage.Premium If you are running I/O input/output intensive enterprise workloads on-premises, we recommend that you replicate these workloads to Premium Storage, said Poornima Natarajan, a Microsoft Cloud and Enterprise manager.CEO Satya Nadella At the time of a failover of your on-premises environment to Azure, workloads replicating to Premium storage will come up on Azure virtual machines running on high speed solid state drives SSDs and will continue to achieve high-levels of performance, both in terms of throughout and latency.EncryptionNatarajan also gave customers more information about the upcoming Azure Storage Service Encryption SSE for data at rest.SSE for Data at Rest will help customers protect their data to meet company regulations, according to Natarajan, with Storage Service Encryption encrypting data prior to persisting to storage and decrypting prior to retrieval.
