Magnetic HDDs still cheapest in 2020
According to a new study, if HDDs continue to progress at their current pace, then in 2020 a two-disk, 2.5-inch disk drive will be capable of storing more than 14 TB and will cost about $40 (today, a typical 500 GB hard drive costs about $100). Although flash memories have also become popular - with advantages such as lower power consumption, faster read access time, and better mechanical reliability than HDDs - the cost per GB for flash memories is nearly 10 times that of HDDs. In addition, flash memory technology will reach technical limits that will prevent its continued scaling before 2020, keeping them from replacing HDDs.
In a study published in a recent issue of IEEE Transactions on Magnetics, Professor Mark Kryder and PhD student Chang Soo Kim of Carnegie Mellon University have investigated 13 up-and-coming NVM technologies to see whether one of them might outperform HDDs on a cost-per-TB basis in 2020. Their results showed that most technologies will probably not be competitive with HDDs or flash memories at that time, except for two potential candidates: phase change random access memory (PCRAM) and spin transfer torque random access memory (STTRAM).
As Kryder and Kim explained, PCRAM is based on the phase change properties of chalcogenide glass. With the application of heat, the glass can switch between two different states (amorphous and crystalline) to be used as a memory. With their small cell size and ability to store multiple bits per cell, PCRAMs have the potential to offer high densities and be cost-competitive with HDDs, but their biggest drawback is that they require somewhat higher power than most other technologies. PCRAMs are already beginning to be marketed by Numonyx Inc., an Intel-ST Microelectronics joint venture, and so are closer to practical realization than STTRAM.
STTRAM, which is similar to magnetic RAM, uses a spin polarized current to write data by reorienting the states of a magnetic tunnel junction between parallel and anti-parallel orientations. In their evaluation, Kryder and Kim found that STTRAMs appear to potentially offer superior power efficiency, among other advantages. If STTRAMs could be improved to store multiple bits per cell, the researchers predict that STTRAMs
Cooler Master LAB test bench v1.0 review
Cooler Master designed the Cooler Master LAB Test Bench v1.0. It's what has been missing here at the lab alright, a nice looking, easy to use chassis where we can pop on and off hardware components, it makes motherboard, cooler and RAM testing really easy. And as simple as this product is, we really like it. And rest assured we'll be using it with pretty much any future motherboard review. It's not a suitable product for everybody, but if it applies to you we can wholeheartedly recommend it.

NZXT releases Gamma Classic Series Case
NZXT expanded its Classic Series of PC cases with the Gamma. This all-black ATX mid-tower intends to provide the essentials of casing the PC of today, while attempting to be creative with its bezel design to the extant possible. It measures 190 X 449 X 508 mm (W x H x D), and weighs 6 kg. The case material is steel, including a dash of meshed steel in the front-panel. The front-panel includes four 5.25" drive bays, audio, USB, and eSATA connectors, and perforated steel to cover the front intake fan.
The interiors are all-black, with seven internal 3.5" drive bays. Apart from openings that help in cable management, the motherboard tray has an opening that makes working with CPU coolers with back-plates easier. The ventilation system provides a lot of room for expansion: a 120 mm intake fan, two side 120 mm fans, a rear 120 mm, and another two 140 or 120 mm fans on top. Ports for water-tubing are included. It is available in Europe, for a price of 39.90 EUR.
25W Athlon II to launch in Q4
Yep that is right .. 25W. AMD will launch a Athlon II X2 260U with a extremely low 25W TDP for OEM in Q4. This will be the first 25W Athlon II X2 based on 45nm Regor. The processors is clocked at 1.8GHz and hasa 2MB cache, comes with support for DDR3 1066 on an AM3 socket. Some faster models will show up after 2010 with revised Regor dual-core.
Athlon II X2 260U will replace 1.8GHz Athlon X2 6850e,which is based on 65nm dual-core with 22W TDP -- Athlon II X2 260U obviously will return better performance.
USB 3.0 Delayed until 2011
Meanwhile AMD and NVIDIA have criticized Intel which seems to purposely dragging its feet on this despite of 3.0 controller spec eventually by Intel. The manager explains that Intel teams prefers its own optical cable interface, Light Peak with 10Gbps of transfer speed ,which is expected to show up early next year.

Burger King Japan sells Windows 7 burgers
An rather unusual Windows 7 launch campaign can be found in Japan with Burger King's launch of a Windows 7 Whopper.
Fitting in with the software theme, the burger stacks seven patties in an otherwise normal Whopper and measures 5.1 inches tall. It also has an appropriate 777 yen ($8.53) price.
The stunt isn't unique for Microsoft's Windows 7 launch, which in the run-up to Thursday's introduction has repeated the "seven" theme in multiple publicity events; it launched a giveaway of the new OS for every resident of the Dutch village of Zevenhuizen ("Seven Houses") and decorated parts of the Spanish village Sietes ("Sevens") in Windows-themed colors.
The campaign contrasts sharply against the more traditional ads of Vista and earlier Windows releases, highlighting Microsoft's desire to turn around its public image.
In North America, most of the developer's less conventional advertising has centered around promoting Windows 7 house parties and its first retail stores.

Core i5 650 ''Clarkdale'' Reaches 4.70 GHz on Air
And that's air-cooling of course. Intel is set to reelase dual0-core Core i5 processors early next year and as it seems, overclock potential certtainly does not suck. Tech powerup reported that Romanian tech community Lab501. Lab501 community leader "Monstru" tested the overclocking headroom of a Core i5 650 LGA-1156 dual-core processor (engineering sample) with air-cooling.
The test setup consisted out of a
- Gigabyte P55 motherboard
- Core i5 650 processor
- Noctua NH-U12P cooler onto which a Coolink SWIF 2 120P fan was strapped.
The chaps reached a nice clock speed of 4.70 GHz (25 x 188 MHz) which is roughly double the original clock frequency. A core voltage of 1.424V was used.
A point here to note however, is that the retail Core i5 650 will come with an upwards-locked bus frequency multiplier of 24 (24 x 133 MHz = 3.20 GHz). The processor at 4.70 GHz, was Prime95-stable for over 30 minutes. With an ambient temperature of 24
