SanDisk releases new SSDs for old computers

Company pitches that replacing an existing hard drive with an SSD is more cost effective than purchasing a new computer

SanDisk has introduced a new line of solid-state drives (SSDs) that it's marketing directly to retail consumers versus computer system manufacturers.

SanDisk's new Ultra SSD

SanDisk is pitching its new Ultra SSD line as a product that can be used to replace hard drives in older systems and thereby increase the performance, durability and lifespan of existing laptops and desktops.

There is nothing that differentiates the new SSD line from a product marketed to equipment manufacturers other than it's being packaged for retail sales.

The Ultra SSD line, which uses the SATA 2.0 specification I/O interface, sports a sequential read rate of up to 280MB/sec and a sequential write rate of up to 270MB/sec.

SanDisk claims the SSD, which is based on multi-level cell (MLC) NAND flash memory, has a mean time between failure (MTBF) rate of up to one million hours.

Most SSD industry experts do not believe MTBF is an accurate way to determine a products longevity as it relates to a the failure rates based on a representative group of shipped products and not the testing of individual drives.

That said, today's MLC-based SSDs have special firmware that helps extend the longevity of the product for up to 10,000 erase-write cycles, meaning a drive can be written to as many as 10,000 times.

Kent Perry, director of product marketing for SanDisk, pointed out that replacing an existing hard drive with an SSD is more cost effective than purchasing a new computer.

The new Ultra SSD line comes in drive 60GB, 120GB and 240GB capacities and retails for $129.99, $219.99 and $449.99, respectively.

U.S. consumers can order the drive now from online retailers such as Newegg.com, where prices are significantly lower than the suggested retail.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
