CES 2009

Both SanDisk and Samsung announced solid-state drives on Tuesday--though that's where the similarity ends. SanDisk's SSDs are aimed at Netbooks, while Samsung's new SSDs are for the high-performance server market.

SanDisk is debuting its new 8GB, 16GB, 32GB, and 64GB pSSD-P2 and pSSD-S2 solid-state drives at the Consumer Electronics Show in Las Vegas this week. Samsung's 100GB SS805 drive, on the other hand, is being introduced on Tuesday at the Storage Visions 2009 Conference, also in Las Vegas.

The second-generation SanDisk drives, designed as drop-in replacements for hard-disk drives, use the Serial-ATA or SATA interface. First-generation drives were based on a slower Parallel-ATA or PATA interface.

New Netbooks such as the Acer Aspire One and the HP Mini 2140 use the SATA interface. (Many ultraportable notebooks, like the first-generation MacBook Air and HP Compaq 2510p, however, used the slower PATA interface.)

"Netbooks represent the fastest growing PC segment in 2009 and 2010 yet widespread adoption of SSDs in netbooks has been limited by speed, capacity and cost constraints," Rich Heye, senior vice president and general manager for solid-state drives at SanDisk, said in a statement. "With the significant improvements in performance, capacity and low pricing, these SSDs are a perfect fit for the exploding Netbook market."

SSDs are generally faster than hard-disk drives, particularly at booting and launching applications, taking about half the time of an HDD, according to SanDisk.

SanDisk's drives, slated to be available in February, 2009, are built using the company's 43-nanometer Multi-Level Cell (MLC) flash memory. MLC technology generally yields lower-cost SSDs compared with more traditional Single-Level Cell or SLC technology. SanDisk manufactures the flash memory in Yokkaichi, Japan with its partner Toshiba.

SanDisk did not provide pricing information but said its 32GB modular SSD is "priced at parity" with 80GB 2.5-inch HDDs in OEM quantities. HDDs with this capacity range in price from about $50 to $100 (depending on speed) so this is rather vague pricing guidance.

Unlike SanDisk's consumer SSDs, Samsung's SSD is targeted at the very-high-end corporate enterprise market. Samsung uses more pricey (and faster) SLC technology since its drives are targeted as a replacement for the high-performance 15,000 rpm hard-disk drives that are the staple storage device of large corporations. These drives are typically used for applications such as video on demand, streaming media content delivery, internet data centers, virtualization, and on-line transaction processing.

Samsung claims its 100GB Enterprise SSD can process IOPS (input/output per second) more than 10 times faster than the fastest 15,000 rpm SAS (Serial Attached SCSI) HDD available for transactional data workloads.

The high-performance 2.5-inch enterprise drive reads data sequentially at 230 megabytes per second (MB/s) and writes sequentially at 180 MB/s, Samsung said. The 100GB SSD's performance is derived from an 8-channel controller, improved NAND flash and special drive firmware, all developed by Samsung.

The 2.5-inch drive will be available this quarter.

One of the many laptops being announced at CES this week is the Toshiba Qosmio X305-Q725. It will offer the same bells and whistles of recent X305s, except that its primary drive will consist of a 64GB solid state drive, while the secondary drive will be the standard spindle-based 320GB SATA hard disk drive. This hybrid solution will not only boost performance on an already beast of a machine but will also help with its typically lackluster battery life--as with most gaming laptops--not by much, but it's something.

Here's a quick look at the specifications:

• Intel Core 2 Quad Q9000 2GHz
• 4GB DDR3 SDRAM
• Primary drive: 64GB Serial ATA SSD
• Secondary drive: 320GB (7200 RPM) SATA HDD
• Windows Vista Ultimate (64-bit)
• NVIDIA GeForce 9800M GTX, 1GB GDDR3 discrete graphics
• Data: USB v2.0--four ports with USB Sleep and Charge (1 x eSATA/USB combo port)

The Toshiba Qosmio X305-Q725 will be available at launch on January 6 and will retail for $2,699 at Toshiba's Web site.

Updated on December 18 at 3:25 p.m. with pricing information.

Toshiba said Wednesday that it will showcase a 512GB solid-state drive at the Consumer Electronics Show next month and begin shipments in the second quarter of 2009.

To date, this would be one of the largest-capacity solid-state drives for use in laptops and come close to matching the size of mobile hard-disk drives.

Samsung has begun mass production of a 256GB SSD and Micron Technology is readying a 256GB drive that will ship in March.

Toshiba said it is releasing a broad family of "fast read/write SSDs" based on 43-nanometer Multi-Level Cell (MLC) NAND flash technology that will be showcased at CES. MLC technology allows solid-state drive makers to deliver higher capacity drives at lower prices.

In addition to the 2.5-inch 512GB drive, the new series of Toshiba drives also includes capacities of 64GB, 128GB, and 256GB, offered in 1.8-inch or 2.5-inch drive enclosures or as SSD Flash Modules, the company said in a statement.

Samples of the new drives will be available in the first quarter of 2009, with mass production slated for the second quarter, in the April to June time frame, according to the company.

Pricing in sample quantities ranges from $220 for the 64GB drive to $1,652 for the 512GB drive, Toshiba said.

The drives achieve a maximum sequential read speed of 240MB per second (MBps) and maximum sequential write speed of 200MBps. This is roughly the same read-write speeds offered by Samsung on its 256GB SSD.

Toshiba said it sees SSDs growing to approximately 25 percent of the notebook market by 2012.
