This was the only place we could find these HP Fiber Channel ATA drives for our EVA M6412 storage. We needed some for storage expansion on some legacy systems still in production but HP support had expired. The price was very acceptable considering these were end of sale / service parts. Our storage is still going strong since installation a few months ago. Hope they work beyond the warranty period. I will give an update to my review after warranty expiration. So far so good.
