Super Talent SSD offering, cheaper and faster

“Super Talent sprinkles fairy dust on its “budget” SSD lineup”

Is ‘fairy dust’ the technical term?

“The solid state disk (SSD) market is really starting to heat up. Super Talent threw down the gauntlet with its low-priced MX series SSDs. OCZ then returned the favor with its Core Series SSDs.”

Cheap SSD’s! Yes!

“OCZ held the upper hand with not only lower pricing for its Core Series SSDs, but also the advantage of faster read/write performance. Super Talent’s MX SSDs clocked in with read speeds of 120MB/sec and write speeds of 40MB/sec. OCZ’s Core SSDs feature read speeds of 120 to 143 MB/sec and write speeds of 80 to 93 MB/sec depending on the capacity of the drive in question.”

I like OCZ never heard of Super Talent. I have heard of ‘Super Fantastic Talent Show’ it’s a Japanese game show I believe.

“With OCZ breathing down its neck, Super Talent worked a little magic on its MX drives. The 15GB and 30GB models now feature read speeds of 120MB/sec and write speeds of 60MB/sec. The 60GB and 120GB have the same read speeds, but now have write speeds of 80MB/sec.” (link)

Pricing on 120GB? Ouch! Still out of my wallet range.

Hard drive tech: even more storage?

One of the cool things about hard drive technology is how it has actually kept pace with computer needs. The basic mechanism for hard drive storage, however, does have some fundamental limitations, which manufacturers will have to deal with fairly soon. Bits are currently stored in the orientation of tiny magnets, called ferromagnetic domains, on a hard drive platter. The smaller the domain, the easier it is for that orientation to be scrambled by temperature or stray electromagnetic fields. At a certain size, thermal photons (e.g., heat energy from the surrounding case or the underlying disk) have enough energy to flip a domain’s orientation. Manufacturers will have to keep their domain sizes significantly bigger than that threshold size to ensure data integrity, which puts a ceiling on storage density, one we’re rapidly approaching.

An alternative is to use ferroelectric domains. Unlike ferromagnetic domains, ferroelectric domains have a natural electric field with an orientation that can be used to represent data. Until recently, these haven’t looked that attractive because they have pretty much the same limitations that ferromagnetic domains have, but they lack the cool read-out tricks. Ferroelectric materials, however, do have one big advantage over ferromagnetic materials: they can be used to make really good capacitors. This is exactly what the latest research, published in Nature Nanotechnology, is about. (link)

Samsung comes out with blazing fast 256GB SSD

Samsung Develops World’s Fastest and Largest Capacity 2.5-inch, MLC-based (256GB) SSD with SATA II Interface

Taipei, Taiwan, May 26, 2008 – Samsung Electronics, the world leader in advanced memory technology, announced today that it has developed the world’s fastest, 2.5-inch, 256 Gigabyte (GB) multi-level cell (MLC) based solid state drive (SSD) using a SATA II interface, at the fifth annual Samsung Mobile Solution Forum held here today. Samsung’s new 256GB SSD is also the thinnest drive with the largest capacity to be offered with a SATA II interface.

With a sequential read speed of 200 megabytes per second (MB/s) and sequential write speed of 160MB/s, Samsung’s MLC-based 2.5-inch 256GB SSD is about 2.4 times faster than a typical HDD. Furthermore, the new 256GB SSD is only 9.5millimeters (mm) thick, and measures 100.3×69.85 mm.

Once introduced, the Samsung’s 256GB SSD will mark the largest capacity SSD from the global market leader in SSD sales, effectively eliminating density as a barrier to SSD adoption in the consumer space. (press release on Gizmodo)

Fujitsu designs hard drive for 24 hour heavy use

Maybe I should rethink leaving my computer running 24/7. How do you define ‘heavy use’? Hard drives in servers? Yes. Daily web surfing? No. Fujitsu clearly is aiming this product at big business and technology corporations. Hello? Google? This if Fujitsu, we’ve got some new hard drives we think you’ll love.

The 2.5″ hard disk drives are specifically designed for 24-hour continuous operation and are available in a category-leading capacity of 250 GB and a speed of 7,200 RPM. Sales of the new MHZ2 BK Series will start at the end of July 2008.

Demanding high-frequency usage, servers or data storage systems in enterprise equipment, including ATMs or POS systems in industrial applications, where daily uptime is required.

Another feature of the new series is that it has industry-leading power conservation, requiring a low 2.3 W for read and write operations. The series is one of many new products announced as part of Fujitsu’s Green Policy Innovation program, unveiled in December 2007 to promote energy-efficient products and services as a way to help customers lower their ecological footprint.

Sony’s new technology increases hard drive capabilities

Sony has revealed a new technology it says will make large hard drives possible even with notebooks. Rather than use a traditional magnetic read/write head, the new development uses a hybrid of magnetic and optical technology to greatly increase the density: while the storage itself is similar, media is written to disk using a laser. The extremely small, precise nature allows it to fit far more bits of data on any given area. A full terabit (125GB) can fit on a single square inch — five times the space of conventional hard disks, Sony says. (link)

SanDisk plans new products, including cheap read only flash memory?

SanDisk, which leads the market in retail flash memory, plans to offer a cheap read-only memory card designed to store photos for 100 years.

The memory company, which used the 2007 Consumer Electronics Show as a springboard for its own consumer-electronics efforts, also plans to launch five new CE products within 90 days, SanDisk executives said during an analyst day at its Silicon Valley headquarters.

SanDisk’s unit market share in U.S. flash-card sales has topped 50 percent in all but one month in 2006, according to market researcher NPD, and figures from NPD and SanDisk place the company as the leading flash card retailer in the world, topping rivals in their home Asian markets. The one exception is Europe, where the company has a minority share. In the MP3 player market, where the company has launched its Sansa MP3 player, SanDisk trails Apple by a significant amount, but also has a sizeable leg up on the number three player, Creative.
