The Hewlett-Packard Envy 13 offers an excellent example of what a cutting-edge ultraportable should be--and it moves past the Apple MacBook Air in some important respects, despite its overly ambitious price tag.

First, let me say that I use a MacBook Air as my main machine and am well aware of its merits. That said, it is beginning to look a little long in the tooth when juxtaposed with the Envy 13--which, like the Air, offers an aluminum chassis. I will also draw comparisons with 13-inch MacBook Pro since the Envy seems to fall somewhere between this and the Air.

(See CNET review of Envy 13.)

Let's start with the Envy's engine. The Envy offers a ULV (ultra-low-voltage) processor option that you won't find in any Apple MacBook: a 1.6GHz Core 2 Duo SU9600 that draws a mere 10 watts. This is Intel's highest-performance 10-watt dual-core processor--a crucial power-saving and heat-reducing option for ultra-thin designs like the Envy or MacBook Air. The more widely used SL9600 (which many reviewers mistakenly refer to as ultra low voltage) draws 17 watts.

But HP charges a premium for this processor, too. Selecting the power-sipping SU9600 adds $200 to the cost of the Envy. But at least it's an option.

Next, graphics. The Envy has switchable graphics. What does this get you? More battery life. When plugged in, the Envy uses the "discrete" (standalone) ATI Mobility Radeon HD 4330 graphics processor. When unplugged it switches to the less-power-hungry--and lower performance--Intel integrated graphics.

The truth be told, most of the time users don't need discrete graphics. But it can be a godsend in Windows 7, for example, when doing transcoding--which converts, for instance, a movie on a PC to a format that makes it viewable on an iPhone or iPod. And, of course, discrete graphics is needed for playing demanding games.

The ATI 4330 graphics seem to be more capable than… Read more

SanDisk said Monday that it is shipping memory chips that will allow consumers to store more data on tiny Secure Digital flash cards.

The Milpitas, Calif., company's X4 technology packs four bits of data into each memory cell. To date, flash memory chipmakers typically stored one bit or two bits per cell. Each individual die--or chip--holds 64 gigabits of data, or 8 gigabytes. This is the highest capacity per die in the industry, according to SanDisk.

The technology is not yet shipping in cutting-edge retail products, however: it is currently being used in 8GB and 16GB SDHC (Secure Digital … Read more

Samsung has begun producing a new chip that one day may replace flash memory and that is expected to increase cell phone battery life by more than 20 percent.

The world's largest maker of memory chips said that it is now manufacturing phase-change random access memory (PRAM) in 512-megabit (Mb) capacities.

Phase change memory has been discussed for decades. Intel co-founder Gordon Moore, for instance, wrote an article about the technology that was published in the September 1970 issue of Electronics magazine. And the basic way the technology works hasn't changed. In phase change memory chips, a medium … Read more

Memory chip makers will offer more sophisticated flash drives for smartphones--technology that will be comparable to the solid-state drives found in laptops today.

Today's flash drives, which typically range up to 32GB in capacity in products like Apple's iPhone, often use relatively unsophisticated techniques for reading and writing data. In general, the technology is not very different from that used in basic cell phones or digital cameras, according to Brian Shirley, vice president of Micron's memory group.

But as smartphones--and possible future tablet devices--become more like personal computing devices and less like basic MP3 players, memory chip … Read more

Updated at 9:10 a.m. PDT: adding analyst comments.

On Tuesday, Intel and Micron Technology announced the development of high-data-capacity flash memory technology for flash cards and USB drives.

And in a related announcement, Intel said Monday that it has validated a fix for its new 34-nanometer X25-M solid-state drive, which is based on similar flash memory technology. The bug affects users who set a BIOS drive password. That update is available here.

The two chipmakers, which partner in the manufacture of flash memory chips, said Tuesday that they have developed NAND flash memory capable of 3 bits per … Read more

Toshiba has begun volume shipments of solid-state drives ranging up to 512GB in size, as these hyper-fast storage options bulk up on capacity.

Drives are also offered in 64GB, 128GB, and 256GB capacities and are built on a 43-nanometer manufacturing process using multi-level cell (MLC) technology. MLC technology allows drive makers to increase capacity while keeping production costs under control.

All drives come in either a 1.8-inch enclosure, typically used in ultraportable laptops, or a 2.5-inch housing, the standard size for mainstream laptops.

Toshiba said in December that it would begin shipments of a 512GB drive this year. … Read more

Apple said Tuesday that it has made a $500 million prepayment to Toshiba for flash memory chips and indicated the market is stabilizing.

"The NAND flash market has now begun to stabilize and we expect it to move to a slight demand imbalance," said Apple Chief Operating Officer Tim Cook in Apple's Tuesday earnings conference call. (The call is available as an audio Webcast on Apple's Web site.) The news was reported earlier by Reuters.

"In terms of the Toshiba prebuy, we did a long-term supply agreement with Toshiba, as a part of that, as … Read more

Intel is introducing new solid-state drives with increased performance as these devices find a more welcome home in Windows 7.

Intel said Tuesday it is moving to a more advanced 34-nanometer manufacturing process for its X series of solid-state drives (SSDs). To date, Intel has built drives on a 50-nanometer process. The more advanced process allows for higher data densities, enabling Intel to pack more data onto the same number of flash chips and reduce cost.

Solid-state drives typically offer better performance--in some cases, dramatically better performance--than hard disk drives. But SSDs cost more per gigabyte than hard drives, limiting their use to performance-sensitive applications such as high-end laptops, gaming PCs, and servers.

The new price for the 80GB version of the X25-M drive is $225 for quantities up to 1,000 units, a 60 percent reduction from the introduction price of $595 a year ago, Intel said. The 160GB version of the Intel X25-M drive is now $440, down from $945 at introduction.

However, the actual price drop in the market will be lower, Troy Winslow, marketing manager for the NAND Products Group at Intel, said in a phone interview. Intel had already announced an interim price reduction in January, below the original $595 and $945 price tags, he said.

"In the marketplace it will be around a $100 drop on the 80GB drive and almost a $200 drop on the 160GB drive," he said. The X25-M comes in a standard 2.5-inch form factor, which is the size of most hard drives used in laptops.

Winslow also addressed rumors circulating on Monday about higher-capacity drives. Intel will not introduce a 320GB SSD this year, he said. "What we decided to do is split 34-nanometer into a two-step process," he said. The first step will be to cost-reduce existing 80GB and 160GB drives. "And what we'll do later--and it's not even going to be this year but first half of next year--we will introduce, also on 34 nanometer, a performance enhancement and a doubling of the capacity," Winslow said, meaning that larger capacity drives, such as those over 300GB, won't appear until next year. … Read more

Back in the day, Netbooks ran Linux and packed solid-state drives. But Windows XP and big hard disk drives have prevailed.

The early Asus Eee PCs--which almost single-handedly created the Netbook market--came with a Linux operating system and small-capacity solid-state "flash" drives ranging from 2GB to 8GB. Early Acer Aspire Netbooks were also offered with Linux and a solid-state drive.

Those devices bore little resemblance to PC laptops. The Eee PC was a tiny, stripped-to-the-bone device that required minimalist hardware to run an efficient Linux OS. (Will a wave of Google Chrome OS-based devices revive the minimalist … Read more
