WD says it has reimagined the hard drive by announcing a new flash storage architecture called OptiNAND. The company is launching new technology in its 20TB CMR-based SSDs that store data on 9 plates and provide storage capacity of up to 2.2TB per plate. Currently, drives are sampled with select customers and the price is still to be determined later.
WD's new hard disk storage architecture, which combines traditional spinning disks with OptiNAND technology, demonstrates greater capacity, performance, and reliability. The drive adds a built-in iNAND UFS drive which, combined with the proprietary operating system and SoC improvements, meets the storage needs of the company's customers.
This idea sounds like existing solid state memory (or SSHD) drives. , which uses smaller, faster memory for short-term storage to increase speed and uses turntables for permanent storage. However, WD says OptiNAND differs in terms of performance because it uses UFS memory to store drive metadata rather than user data.
The company did not specify the capacity of its iNAND processor, but indicated that memory is in use. For storing redundant metadata (RRO), which can be up to several gigabytes and usually takes up disk space when it comes to older hard drives. This newer technology allows for more capacity and faster access to data stored on the disk.
WD is sampling OptiNAND at 20 TB. ePMR is working with select customers and plans to announce pricing and availability to the public later this year. OptiNAND technology is also being introduced in more storage products, and the brutal 50TB ePMR model is expected to arrive in the second half of this decade.
