All mainstream disk array suppliers seem to be raising prices. Here's what Hitachi Data Systems, the latest one to do so, says:
As with other companies in our industry, HDS has witnessed a global cost increase from hard disk drive (HDD) manufacturers due to the devastating floods in Thailand. To date, Hitachi has absorbed these price increases; however, on February 1, 2012, we will have to raise the list prices of the HDDs we sell by 5-15 per cent to offset the cost increases being passed to us from our suppliers. We expect the increases to be temporary until the industry returns to a more stable production level.
