SanDisk introduce 32GB 2.5″ Solid State Disk

You may recall that we reported about SanDisk’s 32GB 1.8″ Solid State Disk a few months ago. SanDisk have just announced the 2.5″ version of the drive with the following press release:

SanDisk today broadened its solid state drive (SSD) product line for the portable computer market with the introduction of a 32-gigabyte, 2.5-inch Serial ATA (SATA) interface model, compatible with most mainstream notebook designs. Coming just two months after SanDisk introduced a 1.8-inch SSD for ultraportable notebooks, the 2.5-inch SSD is now available to PC manufacturers as a drop-in replacement for hard disk drives.

“The SanDisk 2.5-inch SSD brings the extreme durability, outstanding performance and low power consumption of solid-state flash memory to the entire notebook computer market,” said Amos Marom, vice president and general manager of the Computing Systems division at SanDisk. “As SanDisk continues to drive innovation in flash memory, the per-gigabyte price of SSD storage will come down and SSD capacity will go up. PC manufacturers and consumers will find it easier and easier to move away from rotating hard disks to the superior experience of SSDs.”

The vast majority of notebook computers manufactured today use 2.5-inch hard disk drives. The SanDisk 2.5-inch SSD fits in the same internal slot as 2.5-inch hard disks, so notebook manufacturers can switch to the SanDisk SSD without altering their hardware designs.

The key benefits of SanDisk SSDs for computer manufacturers and their customers are:

Reliability. SanDisk SSDs deliver 2 million hours mean time between failures (MTBF)2, approximately six times more than notebook hard disks. With no moving parts, SanDisk SSDs are also much less likely to fail when a notebook computer is dropped or exposed to extreme temperatures.

Performance. In notebook computers, data moves to and from an SSD more than 100 times faster than data moving to and from a hard disk. SanDisk SSDs offer a sustained read rate of 67 megabytes (MB) per second3 and a random read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte transfer4. As a result, notebooks equipped with a 2.5-inch SanDisk SSD can boot Microsoft® Windows® Vista™ Enterprise in as little as 30 seconds5 and access files at an average speed of 0.11 milliseconds6. A notebook using a hard disk requires an average 48 seconds to boot and an average 17 milliseconds to access files.

Power efficiency. SanDisk SSDs have minimal power requirements, with savings rated at over 50 percent compared with a hard disk drive — 0.9 watts during active operation versus 1.9 watts7. This is particularly important in extending battery life for road warriors, enabling them to remain productive while in transit.

Cool and quiet. Because SanDisk SSDs don’t need a motor, bearings or a moving head mechanism, they generate much less heat than hard disk drives. SanDisk SSDs are also completely silent, while hard disk drives always make at least some noise during read and write operations.

“There are several reasons computer users and manufacturers should consider SSDs as prices become more affordable,” said Joseph Unsworth, Principal Research Analyst for flash memory at the Gartner research firm. “For example, Gartner research shows hard disk failure is tied for first place with motherboard failure as the leading cause of overall hardware failure in notebooks, with each accounting for 25 to 45 percent of the total8. The higher reliability of SSDs lowers total cost of ownership, and could be a driver for adoption of SSDs. This is part of the explanation of why Gartner projects global consumption of SSDs in consumer and business notebooks to leap from about 4 million units in 2007 to 32 million units in 20109.”

The 32GB, 2.5-inch SanDisk SSD is available now to computer manufacturers, with initial pricing of $350 for large volume orders. SanDisk SSDs will be demonstrated at the CeBIT show in Hannover, Germany, from March 15 to 21, 2007, in Hall 23, Stand B28, and will be featured on March 16 during the PressExpoUSA @ CeBIT 2007 event.
