Thailand Floods Threaten HDD Supply Chain

The worst flooding in more than 50 years in Thailand could result in a global shortage of HDD supplies, storage analyst IHS iSuppli has warned.

Thailand, home to a large number of manufacturing facilities – which produce one-quarter of the world’s hard disk drives – is being hit hard by heavy flooding that may directly affect the movement of hard drives into the various markets.

Storage analyst IHS iSuppli said in a flash market report 17 October that Thailand’s worst floods in more than 50 years could lead to a shortage of HDD supplies during the current quarter and that this situation may continue into the first quarter of 2012.

Constrained Supply

“While it is too early to gauge the extent of the impact of the floods, HDD supplies are likely to be constrained throughout the fourth quarter [of 2011],” according to IHS storage analyst Fang Zhang.

IHS’s current HDD forecast, published before the disaster, calls for the production of 176.2 million hard drives during the fourth quarter, representing 25.9 percent of annual manufacturing in 2011. IHS likely will downgrade its fourth-quarter production forecast in light of the impact of the disaster, Zhang said.

The floods, which have swept the country for the last two months following torrential rains, may have affected operations for the supplier of a key HDD component: the motor.

Nidec Corp. supplies more than 70 percent of all global HDD motors, and all the major HDD manufacturers – including Western Digital, Seagate, Hitachi GST, Toshiba and Samsung – source motors from Nidec. Nidec has two subsidiaries in the country: Nidec Electronics and Nidec Precision, both located in Ayutthaya in northwest Thailand.

Production Halted

Western Digital, the world’s No. 1 HDD supplier in terms of sales volume, and Toshiba have temporarily halted production of HDDs in Thailand, affecting a major portion of global hard-drive manufacturing. The companies operate HDD assembly facilities in Pathum Thani province near Bangkok.

WD has 37,000 workers in Thailand, and production in the country accounts for 60 percent of the company’s total capacity. WD in the second quarter made 53.8 million HDDs, giving it a 32 percent share of the global market.

No. 2 HDD supplier Seagate, which has about 30 percent of the market, has a head stack and head gimbal assembly facility in Teparuk, Thailand. The company also conducts slider, head assembly and HGA operations in Korat, Thailand. However, both facilities have remained operational following the disaster.

Toshiba employs about 3,900 workers in Thailand, where about 50 percent of the company’s manufacturing capacity is located. Toshiba was the No. 4-ranked HDD supplier in the second quarter of 2011, with 17.8 million units and a 10.6 percent share.
