Leading hard drive manufacturer Seagate is expanding its portfolio to 24TB of storage space. This is the amount of storage offered by the new Seagate Exos X24, intended for use in data centers. Cloud customers can optionally get 28TB, but with a technical drawback.

Just half a year after Seagate introduced its first 22TB hard drive, the company is now announcing its first 24TB hard drive. However, customers must first sample the Exos X24, and Seagate doesn’t expect widespread availability until December.

The Seagate Exos X24 is a 3.5-inch hard drive for server use that uses a traditional recording method (CMR) to store 24 TB of data. However, some commercial customers should be given the opportunity to increase storage capacity through the use of flexible magnetic recording (SMR) to increase to 28 TB. However, this means overlapping data paths, which means that adjacent paths must also be updated when rewritten, which costs performance. Therefore, SMR hard drives are usually only used as archive storage with infrequent or even one-time writes.

Seagate will also continue to offer the configuration flexibility of the Exos

With 24TB (CMR) and 28TB (SMR), Seagate is once again at the top of the storage capacity of traditional hard drives. Western Digital currently offers a maximum capacity of 26TB with SMR, but has also announced samples of a 28TB SMR hard drive.

The HAMR is finally scheduled for commercial launch in 2024

Seagate finally wants the new device next year Red-Making the technology socially acceptable: More than 30 terabytes could then be obtained with the help of a small laser in the writing head. Today Seagate says that “Production is scheduled to begin in early 2024However, because HAMR hard drives frequently delay, this information should be viewed with caution.
