Seagate introduces Mozaic 3+ HAMR Hard Drives with Over Seven Years of Durability

Seagate is stirring up the tech industry with its new Mozaic 3+ hard drive platform, which is based on heat assisted magnetic recording (HAMR) technology. This marks the first major advancement in hard drive technology in a decade, but it also raises concerns about its reliability. To address these concerns and promote their HAMR drives, Seagate has shared details about their research and development efforts in a recent blog post.

According to Seagate, the reliability of Mozaic 3+ drives is on par with traditional hard drives that use perpendicular magnetic recording (PMR). In fact, the components of HAMR HDDs have shown a 50% increase in reliability over the past two years. Seagate claims that Mozaic 3+ drives have impressive durability metrics, with their read/write heads capable of handling over 3.2 petabytes of data transfer during 6,000 hours of operation. This is 20 times more data transfer than typical nearline hard drives. The company rates these drives for a mean time between failure (MTBF) of 2.5 million hours, which is comparable to PMR-based drives.

Seagate’s field stress tests, involving over 500,000 Mozaic 3+ drives, have shown that the heads of these drives can last over seven years, surpassing the lifespan of current PMR-based drives. Typically, customers expect PMR drives to last between four and five years with average usage, so these HAMR drives exceed those expectations.

Seagate is committed to ensuring a smooth transition from PMR to HAMR drives for customers. They aim to make sure that these new drives can seamlessly integrate into existing data center infrastructures without requiring any changes to enterprise specifications, warranty conditions, or form factors.

MTBF: MTBF (Mean Time Between Failures) is a measure of reliability used in the computer industry to determine the average time a system or component can be expected to operate without failure. It is a measure of the average time a system or component can be expected to operate without failure. MTBF is used to determine the expected lifetime of a system or component, and is used to compare the reliability of different systems or components. It is also used to determine the expected maintenance intervals for a system or component, and to determine the expected cost of ownership for a system or component. MTBF is an important metric for the computer industry, as it helps to ensure that systems and components are reliable and cost-effective.
