LAKE FOREST, CALIF. – Mar. 19, 2008 – WD® (NYSE: WDC) announced today that it is now shipping in volume its WD Caviar® SE16 640 GB 3.5-inch hard drives based on 320 GB-per-platter technology -- a platform that it has been shipping since January 2008 and is serving as the foundation of all of the company's 3.5-inch drive families.

Ideal for data-intensive applications, high-performance computing and multimedia systems, the WD Caviar SE16 640 GB drives deliver high performance with their extreme areal density, 3 Gb/s transfer rate, and Native Command Queuing (NCQ). Its two-platter design promotes cool, quiet operation in a high-capacity drive.

"The 640 GB capacity point will be an important one for our desktop customers, and WD is leading high-volume shipments to the channel and OEM customers,” said Don Bennett, general manager and vice president of WD's desktop business unit. "Two-platter hard drives have always been the perfect balance of value, capacity and performance for many of our customers.

Today's common two-platter drives are limited to 500 GB, but we are expanding capacity by 28 percent on the same design with WD's leading technology heads and disks.”

The 320 GB-per-platter technology is being deployed across WD's desktop, enterprise, consumer electronics and external hard drive product lines, including additional capacity points, throughout this calendar year.

I may be wrong, but I thought Hitachi already had a 1 TB HD that was a three platter. If thats the case, then that would be roughly the same capacity per platter. This means we should be seeing HD's with capacities greater than 1 TB very soon. For a 640 GB HD, $140 isn't a bad price either.

great artcicle and over 1 tb would be a hugh breakthrough if they were able to do that 


After some further thinking I looked into buying one and both and are sold out and took down the add to cart link. I guess I'm not the only one who thinks these are hot.

Also I  did some checking and found out it is Samsung that has the 3 platter 1 TB HD's. Odd that they didn't come out with a 2 platter 640 GB HD before WD since they already had the technology to do so. 


I really like the drives with a single 320GB platter.They are more silent than others
