Secure Data Recovery's March 8 post broke down the HDDs it received for data recovery by engineer-verified 'power-on hours,' or the total amount of time the drive was functional, starting from when its owner began using it and ending when the device arrived at Secure Data Recovery. 'Most' of those drives were 40GB to 10TB, according to a blog post by Secure Data Recovery spotted by Blocks & Files on Thursday. The statement comes from a Los Angeles-headquartered HDD, SSD, and RAID data recovery firm aptly named Secure Data Recovery that has been in business since 2007 and claims to have resolved more than 100,000 cases.

Īn analysis of 2,007 damaged or defective hard disk drives (HDDs) has led a data recovery firm to conclude that 'in general, old drives seem more durable and resilient than new drives.' Further, eight of the 13 SMR drives from Western Digital and Seagate registered fewer than 15,000 power-on hours on average. The firm found that, 'Western Digital's SMR models had a 12.7 percent shorter lifespan than their CMR counterparts, Seagate's SMR models had a 19.7 percent shorter lifespan than their CMR counterparts,' when looking at average power-on hours. It said that 37 percent of the Western Digital and Seagate drives analyzed featured SMR.

Update : Secure Data Recovery provided us with a little more information on the defective HDDs tested.
