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.

Toshiba has unveiled solid-state drives based on the new mini-Sata interface standard, which lets manufacturers create very small drives for use in Netbooks and other portable or embedded devices.

The Japanese hardware maker introduced on Monday the two 32-nanometer-process SG2 SSD modules, each of which comes in two capacities. In a separate announcement the same day, the Sata-IO consortium said it is developing mini-Sata (mSata).

The new interface specification will provide a "high-performance, cost-effective storage solution for smaller devices like notebooks and Netbooks," said the Sata-IO consortium, which includes Toshiba.

One of Toshiba's SG2 modules uses an mSata interface, while the other uses a standard Sata II connector in a "Half-Slim" caseless format. The modules, which come in capacities of 30GB and 62GB, are each smaller than a business card, according to the manufacturer. The mSata module measures 30mm x 4.75mm x 50.95mm, while the Sata II module measures 54mm x 4mm x 39mm.

The company said that the 62GB version of the module is one-seventh the volume and one-eighth the weight of the standard 2.5-inch SSDs currently used in Netbooks.

"Our latest 32nm mSata and Half-Slim caseless modules enable hardware designers to add the performance and reliability advantages of a solid-state drive in a smaller, footprint for notebooks, portable electronics and other embedded storage applications," Toshiba memory chief Scott Nelson said in a statement.

The SG2 modules have interface speeds of up to 3Gbps, a maximum sequential read speed of 180MBps, and a maximum sequential write speed of 70MBps. The modules will go into volume production in October, Toshiba said.

Other manufacturers working on the mSata specification include Dell, Hewlett-Packard, Lenovo, Samsung, SanDisk, and STEC.

A Fujitsu laptop, a high-end video camera, and a solid-state drive using USB 3.0 technology, among other hardware, will be demonstrated at IDF, according an announcement from the USB Implementers Forum on Thursday.

USB technology is now used on virtually all computing devices globally as well as the lion's share of consumer electronics products. Also referred to as "SuperSpeed USB," next-generation USB 3.0 boosts the data transfer rate 10 times over current technology, while also improving power efficiency.

Consumer electronics devices enabled with USB 3.0 are expected in the market late this year or early next. The specification was developed by Intel, Hewlett-Packard, Microsoft, NEC, ST-Ericsson, and Texas Instruments.

On display at IDF, among other things, will be a Fujitsu laptop, the first to use built-in USB 3.0. Inside the Fujitsu laptop will be an NEC Electronics "host controller" chip that will exchange data with an external SuperSpeed USB drive from Buffalo Technology.

And USB 3.0 will be a godsend to video cameras--which often need to transfer gigabytes of video data. A prototype high-performance digital video camera from Point Grey Research will be rolled out that integrates a 3-megapixel Sony "IMX036" CMOS (complementary metal-oxide-semiconductor) image sensor to output 1080p high-definition images at 60 frames per second. This camera will stream uncompressed HD video to a laptop PC through a SuperSpeed USB ExpressCard from Fresco Logic.

Asus will also be present to show off its PC motherboard with SuperSpeed USB. The Asus X58 motherboard uses the same NEC chip and will exchange data with a LucidPort SuperSpeed USB mass storage device running the new USB Attached SCSI Protocol (UASP), which delivers improved performance and reduced latency.

The demonstrations will take place during two USB 3.0 technical sessions at IDF at the Moscone Center, San Francisco, starting on Tuesday.

Intel and Microsoft will hold an event next week to discuss collaboration on improvements to Windows 7.

The event, on September 1 in San Francisco, will "share how the two companies collaborated on key enhancements during the development of Windows 7," according to Intel. Steve Smith, vice president and director, Intel's Digital Enterprise Group Operations, and Michael Angiulo, general manager of Windows Planning and PC Ecosystem at Microsoft, will talk at the event. Microsoft plans to launch Windows 7 on October 22.

Windows 7 collaboration will be demonstrated by engineers from both companies, according to Intel. Not surprisingly, Microsoft is working closely with Intel, whose chips will power the vast majority of PCs running Windows 7.

In a blog posted in July, Intel described how Microsoft and Intel "saw unique opportunities to optimize Windows 7 for Intel processor technology" in the areas of performance, power management, and graphics.

The blog discusses improvements to multitasking based on "SMT Parking," which provides additional support to the Windows 7 scheduler for Intel Hyper-threading Technology. With Hyper-threading, the operating system sees a single processor core as two cores (i.e., a dual-core chip becomes a virtual quad-core processor), thus potentially improving multitasking--or doing tasks (threads) simultaneously.

In addition, improvements over Vista for boot and shutdown times have been implemented during the Windows 7 development cycle, according to the blog.

And on Intel's Web site, the chipmaker lists desktop motherboards and associated drivers that have passed logo certification for Windows 7.

Another beneficiary of improved Windows 7 technology: Intel solid-state drives, which are typically faster than hard-disk drives and gaining ground in niche markets such as high-end laptops, gaming PCs, and servers. SSDs will be able to take advantage of Windows 7 technology called the Trim Command. Trim will allow blocks of data to be freed up for reuse to better maintain the performance of the SSD.

Windows 7 will also do more than previous operating systems with graphics via DirectX 11. Advanced Micro Devices has described DirectX 11-related technology that enables games developers to create smoother, less blocky and more organic looking objects in games. And, beyond games, Windows 7 has the potential to turn a graphics processing unit (GPU) from AMD or Nvidia into a general-purpose compute engine, used to accelerate everyday computing tasks like a central processing unit, or CPU. Specifically, "the compute shader" can be used to speed up more common computing tasks. The buzz word used to describe this technology is a mouthful: GPGPU or general-purpose graphics processing unit.

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 makers will begin offering more sophisticated flash memory, said Shirley, in a phone interview.

"In nearly all MP3 players today it's almost exclusively 'raw' NAND. And at some point we anticipate moving more to a managed NAND," Shirley said. NAND is the type of flash memory chip used in all flash cards and solid-state drives.

Managed NAND falls somewhere between very basic flash drives--such as Secure Digital, or SD, cards--and pricey solid-state drives (SSDs) used in laptops and servers. "It's something in between the raw NAND that we've been talking about for cell phones and MP3 players and the full-blown SSD space," Shirley said.

"We believe this will be fairly busy (market) space in 2010," he added.

Solid-state drives used in laptops like the Apple MacBook Air and Dell Adamo get their performance from highly-developed, sophisticated controller chips and firmware, which manage how the data is read and recorded. Though managed NAND wouldn't necessarily reach this level of sophistication, it would begin to approach it.

The iPhone uses raw NAND with a separate controller, according to Gregory Wong, founder and principal analyst at Forward Insights, which does research on flash memory technology.

"They like to have control over the flash and the controller so they can boost performance," he said. "They're very cognizant of differentiating their products. The user experience is what is important to them. Whether it means you can download your music or video very quickly, whether it means you can find the data very quickly--that ties in to how they manage the NAND," he said.

But even Apple is looking for better performance as it looks to continue its very successful strategy of making its products different, according to Wong.

And future Netbooks may also use this kind of flash memory. Netbooks today using Intel Atom processors and the Windows operating system use, almost exclusively, hard disk drives. But a new category of Netbooks dubbed smartbooks--devices that are always on, always connected, and boast all-day battery life--are expected to come to market in 2010 packing flash drives. These small laptops may be candidates for managed NAND.

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 cell based on 34-nanometer technology. This allows greater data density than the standard 2-bits-per-cell technology and will result in high-capacity USB flash drives, according to Micron.

While packing more bits into a cell provides greater data densities, it is not as reliable as flash memory based on more standard technology, according to Kevin Kilbuck, director of NAND marketing at Micron. Therefore, the 3-bits-per-cell chips will be limited initially to flash drives, which don't require the data storage reliability of a solid-state drive, which is used as the primary storage device in laptops and servers.

"The chip is not for all markets," according to Jim Handy of semiconductor market researcher Objective Analysis, writing in a research note published Tuesday about the technology. "The companies explained that they need more experience in production volumes before they will be confident to position it as a chip suitable for the high-write environment of the SSD," he said. Handy is referring to the fact that users of solid-state drives typically record data at a much greater frequency than consumers who, for example, buy flash drives for digital cameras.

But Handy added that he expects the Intel-Micron chip by 2010 to "cause snags for the other vendors in the market: Samsung, and Hynix/Numonyx" and potentially be more profitable than the competition.

Micron is currently sampling the chips and will be in mass production in the fourth quarter.

SanDisk and Toshiba disclosed in February that they had developed 4-bit-per-cell technology, which the two companies said was the highest-capacity flash memory technology in the industry.

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. And this drive became available exclusively on Toshiba laptops in May.

SSDs typically offer higher performance--often much higher performance--than hard-disk drives and are more durable since they have no moving parts.

But SSDs are still hobbled by a distinct price disadvantage. Toshiba's own Web site offers vivid proof. A Toshiba Portege R600 laptop is priced at $2,099 with a 160GB hard disk drive. Adding a lower-capacity 128GB SSD hikes the price to $2,499. Add the 512GB option and this goes to $3,499.

Back in December of last year, Toshiba said sample quantities ranged from $220 for the 64GB drive to $1,652 for the 512GB drive--though these prices have likely come down, as the drives are now shipping commercially.

For businesses up-front pricing may be less important. Over the lifespan of an SSD total cost of ownership may be lower, according to Gregory Wong, president, Forward Insights. Potential savings are particularly relevant to business laptop users, said Wong. And Intel recently did some in-house testing that showed that failure rates of SSDs are lower than hard disk drives.

On the performance front, Toshiba said it is using an advanced controller chip that enables a maximum sequential read speed of 230 megabytes per second and maximum sequential write speed of 180 megabytes per second. These read-write speeds are typically many times that of a hard disk drive. Toshiba did not specify random read and write speeds, which are also critical benchmarks for everyday data access.

Intel has recently begun shipping a 160GB solid-state drive that offers improved random write performance. The chipmaker was able to get up to a 2.5X improvement over previous versions of its SSDs.

Toshiba is not alone in announcing commercial shipments of large-capacity SSDs. Micron Technology's Crucial Technology unit has begun selling 256GB drives listed at $599, which beats Toshiba pricing at that capacity.

Note: Intel has found a bug in the new SSDs cited above that affects users who set a BIOS drive password. When disabling or changing the password followed by powering off/on the computer, the SSD becomes inoperable. The root cause has been identified and a fix is under validation. Intel expects to post an end-user firmware update to fix this bug in the coming weeks.

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.

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

Toshiba's mini NB200 does not offer a solid-state drive option in featured configurations nor Linux

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 Netbook next year?)

Fast forward to today: Windows XP rules, with a Netbook-specific Windows 7 on the way. A glance at the Netbook lineups from any top PC maker--including Hewlett-Packard, Acer, and Toshiba--reveals few, if any, Linux offerings and equally few solid-state drive options.

Rather, beefy hardware configurations sporting 160GB hard disk drives and as much as 2GB of memory are the norm.

And the momentum for solid-state drives on mainstream laptops is waning too. A report from market researcher iSuppli says higher prices for flash memory chips may undermine high-capacity SSDs in laptops.

Average pricing for widely used 16-gigabit flash chips rose to $4.10 in the second quarter of 2009, a steep 127.8 percent increase from $1.80 in the fourth quarter of 2008, said Michael Yang, senior analyst for mobile and emerging memories at iSuppli, in a report released Wednesday.

As for Linux, time will tell if Netbooks return to their roots with Google's Android and/or the Chrome OS next year.
