Review on Seagate Barracuda 4 TB ST4000DM004 hard drive by Adam Joks ᠌

dishonest business. Hard drive producers employ SMR technology (Shingled Magnetic Recording, sometimes known as "tiled magnetic recording") to boost data recording density, enabling them to fit more data on each hard drive platter. It differs significantly from the more well-known CMR and PMR recording methods in terms of its characteristics. Information is recorded on parallel tracks using CMR (Conventional Magnetic Recording, also known as "ordinary magnetic recording") and PMR (Perpendicular Magnetic Recording, also known as "perpendicular magnetic recording"). SMR, as suggested by its name, layers data tracks like roof tiles, one on top of the other with some overlap. This aspect of SMR really makes it possible to enhance recording density, but it has the unintended consequence of slowing down data rewriting. This setting is crucial for many file servers, making SMR disks incompatible with them. Drives that employ this technology are typically utilized in storages where the information does not need frequent or routine access. Although they are aimed at general consumers and user-level NAS server use, SMR is also present in Barracuda ST2022DM008 (2 TB/7200 rpm), ST4000DM004 (4 TB/5400 rpm), ST8000DM004 (8 TB/5400 rpm), and Desktop ST5000DM000 (5 TB/5900 rpm) hard drives. However, this information is not included in their official paperwork. SMR is utilized in the aforementioned drive models, according to Seagate representatives who spoke with Blocks & Files experts. However, they declined to comment on the absence of SMR from official documents.
