Two other enterprise-class storage vendors have also raised their hard drives prices in as many months, and Lenovo said it had run short of certain drives for its PC systems.
Flooding in Thailand that began in August and lasted about three months wreaked havoc on disk drive manufacturers, in some cases shutting down as much as 75 percent of production.
"Similar to other vendors we have seen a negative impact to our drive costs. While we initially absorbed the cost increases to protect our partners and customers, we are no longer able to do so," NetApp stated in its announcement.
IDC analyst John Rydning said the most "painful period" for drive shortages would last from December 2011 through February 2012.
"We expect the situation will improve, but it won't feel as if things are back to normal until 2013," he said.
In November, Hewlett-Packard sent a letter (PDF) to its customers stating that the reduction in available hard drives had caused "immediate and significant increases in the prices that HP and all other vendors pay for hard disk drives."
Tom Joyce, HP's vice president of marketing, told customers that component prices had risen about 20 percent, forcing HP to increase its prices for certain hard drives. He did not specify which hard drives were included in the price increases.
"In the ordinary course of business, we often adjust prices we charge for components based upon market conditions, and this situation is no exception. What is different now is that some of these component prices may rise significantly, and for an indeterminate period of time," Joyce stated.
Also in November, Lenovo sent an email to its corporate IT customers telling them it is out of a number of hard disk drives, including the highly popular 7,200-rpm models.
In the email obtained by Computerworld, a Lenovo representative stated that customers who normally purchase systems with 160GB 7,200-rpm drives, or various other drives that are unavailable, will have to settle for "off-spec" drives.
Most recently, drive prices on consumer sites have begun to settle down. According to Dynamite Data, the top 50 hard drives on sites such as Newegg.com and Tigerdirect.com, leaped in price by 50 percent to 150 percent after the flooding.
