Seagate confirms that the shingling technology benefit of the latest HAMR mechanical hard drive only increases by about 10%

According to news from this site on January 27, as Seagate officially launched the Mozaic 3 (Magic Color Box 3) platform, more parameters of this heat-assisted magnetic recording (HAMR) mechanical hard drive platform were exposed.

According to foreign media Blocks & Files, one of the more interesting points is that the introduction of Shingled Magnetic Recording (SMR) technology into the Mozaic 3 mechanical hard drive does not bring about as much capacity improvement as other traditional magnetic recording ( CMR) hard drive.

The CMR version of the Seagate Exos Mozaic 3 mechanical hard drive has a maximum capacity of 30TB,while the corresponding SMR version has a capacity only increased to 32TB, an increase of 6.67%; this site has learned that Seagate’s competition The current largest CMR mechanical hard drive of rival Western Digital is 24TB, while the SMR model can reach 28TB, an increase of 16.67%. It can be seen that the capacity increase benefit of introducing SMR technology on Mozaic 3 mechanical hard drive is significantly lower.

Compared with CMR mechanical hard drives, the write tracks of SMR mechanical hard drives can partially overlap, allowing them to be used on the same room for more tracks. However, for the Mozaic 3 mechanical hard drive that uses HAMR technology, the tracks are overall narrower and closer to each other. The introduction of SMR technology cannot explore the capacity potential in a similar proportion as before. Jason Zimmerman, senior director of product line management at Seagate, confirmed to foreign media that Seagate officially observed that on the Mozaic 3 (Magic Color Box 3) platform,

using SMR can bring about 10% more capacity than CMR. income

. Although this value is higher than the 6.67% found on actual products on sale, it is still lower than the level of other mechanical hard drives.
