Huawei is developing a new solution called magnetic electromic disk (MED), thereby promoting the development of file storage technology.The storage device integrates tape and solid -state hard disk technology, which aims to provide a traditional hard disk alternative to achieve high capacity and low power consumption.
The first generation of MED can accommodate up to 72 TB data in the compact 7 -inch shell, which is much lower than the standard hard disk.MED is developed by to alleviate the shortage of supply in traditional hard disks, especially considering the US export restrictions on China.By combining the traditional slow but reliable tape storage with high -speed solid -state hard disks, Huawei has designed a hybrid storage solution that can not only meet the speed demand, but also improve efficiency.
The data was originally recorded on a solid-state hard drive, used for fast access, and then written tapes in order blocks for long-term storage.Frequent access data (or "heat" data) is retained on solid -state hard disks to quickly retrieve, while "cold" data with lower access frequency is stored on the tape.
According to the early specifications, a MED rack can store more than 10 PB data, the power consumption is less than 2000 watts, which is much lower than HDD -based storage.This efficiency can redefine data archiving, especially data archives of large -scale data centers.MEDs data throughput is expected to reach 8 GB/s, which highlights the potential of its high demand environment.
MED is expected to be launched in 2025. The second -generation more compact products will be launched in 2026 or 2027, with a size of 3.5 inches.
