Recently it was discovered that Seagate Technology, Western Digital and Toshiba included Shingled Magnetic Recording (“SMR”) technology into various models of their hard disk drives without disclosing this fact to consumers. Many consumers relied on the statements of the Seagate, Western Digital and Toshiba data sheets and user manuals that did not disclose the use of SMR, an inferior technology to CMR (Conventional Magnetic Recording).
The SMR hard drives are generally considered to be inferior and are often incompatible with many customers’ Network Attached Storage (“NAS”) systems. SMR writes or stores data in a different method where the lines of data overlap, like shingles. This is causing the hard disk drives to perform slower than expected and slowing down customers’ networks.
Here is a list of some of the Seagate drives using SMR without it being identified:
