Getting heavy into HAMR's theory

Subject: General Tech | March 24, 2015 - 12:43 PM |
Tagged: HAMR, science

If you are curious just how Heat Assisted Magnetic Recording is able to increase the storage densities of your HDDs then this post at Nanotechweb and the linked article will make a great read.  They deal with how plasmonic near-field transducers, which will oscillate in time with the frequency of a light source, as long as the light source's frequency is equal to or less than the plasma frequency.  This causes heat but nowhere near as much as if the light was used directly and so avoids potentially damaging hotspots.  They also delve into the materials which are being tested to provide more efficient heat transmission; it is not light reading but it is very informative for those curious about HAMR's development and future.

"Heat-assisted magnetic recording (HAMR) is a leading technology for advancing hard-disk-drive areal density beyond 1 Tb/in2. To reduce the magnetic coercivity, near-field transducers (NFTs) made of plasmonic nanostructures are used."

Introduction and Features

Introduction

EVGA has just announced the arrival of two new GS power supplies in their popular SuperNOVA line, the 550GS and 650GS. Both power supplies are 80 Plus Gold certified and feature all modular cables, high-quality Japanese brand capacitors, and a super quiet 120mm cooling fan (with the ability to operate in silent, fan-less mode at low power levels). The 550GS and 650GS are housed in a compact chassis (150mm deep) and are backed by a 5-year warranty. These new GS units are manufactured by Seasonic and will start selling for $89.99 (550GS) and $99.99 (650GS) this spring.

EVGA was founded in 1999 with headquarters in Brea, California. They continue to specialize in producing NVIDIA based graphics adapters and Intel based motherboards and keep expanding their PC power supply product line, which currently includes twenty-two models ranging from the high-end 1,600W SuperNOVA T2 to the budget minded EVGA 400W power supply.

In this review we will be taking a detailed look at both the EVGA SuperNOVA 550GS and 650GS power supplies. It’s nice when we receive two slightly different units in the same product series to look for consistency during testing.

Here is what EVGA has to say about the new SuperNOVA GS Gold PSUs: “The EVGA GS power supply lineup has arrived. These power supplies offer superior performance, at extremely low noise levels making these the perfect power supplies for a low noise environment. These power supplies also feature ECO mode meaning that the fan will run only when necessary, further reducing noise level and power consumption.

The EVGA SuperNOVA 550GS/650GS power supply raises the bar with 550W/650W of continuous power delivery and 90% (115VAC) / 92% (220VAC-240VAC) efficiency. A fully modular design with compact dimensions reduces case clutter and 100% Japanese capacitors ensures that only the absolute best components are used. This gives you the best stability, reliability, overclockability and unparalleled control. The EVGA SuperNOVA 550GS/650GS is the ultimate tool to eliminate all system bottlenecks and achieve unrivaled performance."

Watercooling your EVGA X99 with Bitspower

Subject: Cases and Cooling | March 24, 2015 - 02:12 PM |
Tagged: evga, X99 Classified, X99 FTW, watercooling, Bitspower, THOR EIX99

Now that most of the features once present on motherboards have been moved to the CPU there is far less need to watercool your chipset.  However for the extreme overclocker there are advantages to cooling the MOSFETs on the VRM and PCH as well as the CPU itself.  Modders-Inc has just reviewed the Bitspower THOR EIX99, specifically designed for EVGA's X99 Classified and FTW motherboards. The acrylic housing for the waterblocks bring a unique look to your motherboard as well as offering improvements to heat management.  By installing the cooler Modders-Inc hit 4.5 GHz on an i7 5960X, not too bad for a $160 investment.  The installation was simple but if you invest the time to design a custom watercooling loop you can get even more performance out of this kit.

"Bitspower makes various options for water blocks that cover Gigabyte, ASRock, MSI, Asus and EVGA motherboards. Recently, we reviewed the EVGA X99 Classified and that motherboard is designed to push the CPU as high as possible if the cooling equipment allows. Bitspower’s THOR EIX99 is specifically designed to cover the EVGA X99 Classified as well as the EVGA X99 FTW motherboard, cooling the critical motherboard components and providing the thermal headroom that the MOSFETs and other parts require for a stable overclock."

Return of the Sharkoon; death to all other mice!

Subject: General Tech | March 26, 2015 - 03:55 PM |
Tagged: input, sharkoon, shark zone m20, gaming mouse

Sharkoon is back with a brightly coloured and reasonably priced gaming mouse, the Shark Zone M20.  It sports nine buttons including the DPI toggle which ranges between 400 - 3200 DPI and in the back is a compartment to hold the weights which ship with the mouse and allow you to customize it.  The yellow lights can be switched on or off and you can set up a pulsation effect if that is your style, but you are stuck with that one colour.  Kitguru found it to be a decent mouse, especially as they could purchase it for half the price of similar gaming mice from other companies.

"We look at quite a lot of gaming mice here at KitGuru, many of them sitting over the £50 mark. But what if you only have £25 to spend? Today we are taking a look at the Shark Zone M20 Gaming Mouse from Sharkoon, it boasts many of the same features found on high-end mice, could this be a hidden gem in the saturated peripherals market?"

In love with smartwatches but want them open source and under $1000?

Subject: Mobile | March 24, 2015 - 07:02 PM |
Tagged: Android, linux, smartwatch

Linux.com offers you a shopping list of smartwatches which are all less expensive than the fruit flavoured models and run Android or Linux.  From familiar models like the Pebble and the older and less impressive Neptune Pine and Omate TrueSmart to leaked models like the Tizen-based Samsung Orbis you have quite a few choices to look through.  There is even  Monohm's large Runcible that is more of a pocket watch than a wrist watch to consider.  In many cases the details are a bit lacking but the model names are known so you can get a leg up on your research for when they are finally revealed with full specifications.

"Much to the delight of Apple fanbots everywhere, Apple has now fully unveiled the Apple Watch. The watch, which was previewed in September, will go on sale April 10 and ship on the 24th. Based on its brand name, styling, accessories, and battery life claims, it will likely be a big hit -- at least as far as smartwatches go."

About time you provided some in game footage, meet Blood Bowl 2

Subject: General Tech | March 25, 2015 - 02:46 PM |
Tagged: gaming, blood bowl 2

The teaser trailer for Blood Bowl 2 has been around for a while but was obviously not representative of what the game will look like in match.  Rock, Paper, SHOTGUN has posted a new video which does feature a look at the new interface for those who find the NFL nowhere near as violent as they like their football.  Cyanide is starting the game out with 8 races so it is possible that some of the more interesting balance issues caused by certain races in the first iteration will be ironed out, hopefully as they include new races they will be available for little or no money for those who purchased the initial release of this sequel.  If you enjoy inflicting turn-based tactical trauma then keep your eyes out for this release.

"We’ve had a little chat with the makers of Blood Bowl II [official site] – and isn’t it nice to chat with people! – and peered at a few screenshots and swish trailers. With spring approaching, and therefore the turn-based tactical bloodsport’s release, we’re at the point in its marketing campaign where we get to see more of the game itself."

Renegade X Beta 4 Released with Trailer

Subject: General Tech | March 29, 2015 - 08:59 PM |
Tagged: renegade x, UE3, udk, unreal engine 3

If you are looking for a game to play, Totem Arts has released their fourth public beta for Renegade X. You have probably heard of the game by now but, if not, it is a third-person shooter that is in the style of Command & Conquer: Renegade. Each team has a base that provides weapons, vehicles, and upgrades in exchange for credits. Players then use this superiority to destroy each others bases (and each other directly of course).

The game is powered by Unreal Engine 3 through the UDK program. From what I can tell, they are using the February 2014 build, which is a little over a year old but relatively up-to-date technologically. Epic Games added most DirectX 11 functionality back in the March 2011 UDK beta release. It looks quite good too.

And it's free (not free-to-play). Check it out.

Can OCZ's Vector change 180 degrees with their new SSD?

If you haven't already done so you should start out with Al's deep dive into the new OCZ Vector 180 SSDs, which uses the Barefoot 3 controller with Toshiba A19 MLC flash and suffers similar issues to other drives using these components.  Once you are done studying you can take a look at other reviews, such as the performance overview at The Tech Report of this drive which is extremely similar to the ARC 100 and Radeon R7 SSDs.  The drives are definitely aimed at the value conscious user, while most are currently not in stock at Amazon, the pricing of 120GB @ $90, 240GB at $185 and 480 at $270 are not bad for initial release.  The Tech Report does plan on doing more testing but from what they saw in their testing the new Vector 180 beats the 150 for performance.

"OCZ's Vector SSDs are among the fastest around, and now there's a new one. The Vector 180 combines the company's proprietary Barefoot 3 controller with Toshiba's latest "A19" NAND. We've taken a closer look at the drive—and OCZ's recent reliability rep—to see what's what."

What helium shortage? I have a bunch stored in my HGST drive

Subject: General Tech | March 26, 2015 - 12:32 PM |
Tagged: hgst, western digital, helium, hdd

The new generation of helium filled HDD from HGST take their longevity seriously, rating them at 2.5 million hours MTBF.  This generation also has 7 disks squeezed into the shell, with current capacities reaching 8TB and a shingled 10TB model currently being tested for release later this year.  The increased life and storage density are only part of the benefits that helium brings, 23% lower operating power and temperatures 4-5°C lower than traditional drives will also have an impact on data centre operating costs.  In their article The Register did ask how long the HelioSeal will keep the helium contained and while they did not get an exact figure, the 5 year warranty gives you a good idea of a lower limit.

"HGST has announced second-generation helium drive tech after shipping a million gen-1 Helium drives and upping field reliability by 15 per cent."
