Computerworld: Apple’s new iMac looks great, even faster; in a month of testing, it never crashed

“The new iMac still looks great, and it’s even faster,”Michael deAgonia reports for Computerworld. “Apple left unchanged the minimalist aluminum-and-glass design while switching to Intel’s Sandy Bridge processors, AMD graphics chips and adding the new Thunderbolt port for high-speed connections with peripherals.”

“All of the changes Apple made to the lineup match the company’s past practice of beefing up hardware while leaving prices intact, yielding a thoroughly modern all-in-one computer, with a sharp, bright screen that’s perfect for editing movies, organizing/editing photos, watching streaming video or making your own presentations,” deAgonia reports. “Best of all, the iMacs come with Apple’s iLife suite of apps — iMovie, iPhoto, GarageBand, iDVD and iWeb. I still haven’t found any software quite as intuitive — or as easy to use — on the Windows side that beats the iLife suite.”

“The best way to describe the benefits of Thunderbolt is to compare its theoretical speed with current standards: USB 2.0 tops out at 480Mbps, FireWire 800 tops out at 800Mbps, USB 3.0 hits 5Gbps and Thunderbolt maxxes out at a theoretical 10,240Mbps, or 10Gbps. For every connection, there are two bidirectional channels that carry data over a 10Gbps pipe — each way — which means you can transfer a lot of data fast,” deAgonia reports. “You can connect a wide variety of peripherals to a Thunderbolt port, from hard drives to displays, daisy-chaining up to six peripherals per port. In fact, it’s possible to take a 27-in. iMac and flank it with two 30-in. displays, streaming multiple 1080p hi-def videos from connected RAID enclosures, without hiccups in the data stream.”

deAgonia reports, “Thunderbolt performance aside, this iMac performs very well under everyday, and even extenuating, circumstances. In a month’s worth of use, the iMac I tested never crashed… Apple has delivered a solid update to what was already a popular and successful line. The Sandy Bridge chips add a speed boost, Thunderbolt offers the promise of peripheral heaven in a few months, and the iMac design itself remains current. It’s equally at home in the boardroom or the living room, and the range of sizes, prices and build-to-order options means it should be easy for most buyers to get exactly the machine they want.”

Samsung Launches Faster High-performance Memory Cards for 4G Smartphones
Posted: 30-Jun-2011 [Source: Samsung] [Samsung announces production of its high-performance microSD cards with advanced data transfer speeds that support the performance requirements on fourth generation (4G) smartphones.]

Seoul, South Korea -- Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today announced production of its high-performance micro Secure Digital (microSD) cards with advanced data transfer speeds that support the performance requirements on fourth generation (4G) smartphones. The new 20-nanometer-class* microSD cards have a class 10 speed rating suitable for seamless data storage and transmission of full HD video, one of the features becoming highly popular among 4G smartphone users.

“The industry demand for high-class-rated memory cards addresses the growing performance push for next generation mobile applications in more advanced smartphones including 4G models,” said Wanhoon Hong, executive vice president, memory sales & marketing, Samsung Electronics. ”As the industry adopts microSD cards with a class 10 rating, the superior data transfer speeds are expected to improve the mobile user experience tremendously.”

The new 32GB microSD cards can write at 12 megabytes per second (MB/s) and read at 24MB/s, providing users with more than double the maximum write speeds of a class 4 rated 32GB microSD card. The new 32GB memory card incorporates 32Gb 3-bit NAND flash memory chips and a proprietary 3-bit NAND controller to deliver the high performance.

The new card follows the introduction of Samsung’s 30 nanometer (nm) class*, 32 gigabit (Gb) 3-bit-per-cell (3-bit) NAND-based 32 gigabyte (GB) microSD cards in February 2010. By applying the finer 20-nm-class process technology, the productivity of the chips is raised over 30 percent.

As an industry pioneer, Samsung plans to continue to aggressively introduce new NAND-based mobile memory solutions for timely market adoption. Mass production of its 20nm-class 64Gb 3-bit NAND designed on advanced toggle NAND architecture is anticipated for early next year.
