WD Red 3TB 3.5 Inch NAS Internal Hard Drive - 5400 RPM - WD30EFRX
About this deal
SMR is tested and proven technology that enables us to keep up with the growing volume of data for personal and business use. We are continuously innovating to advance it. SMR technology is implemented in different ways – drive-managed SMR (DMSMR), on the device itself, as in the case of our lower capacity (2TB – 6TB) WD Red HDDs, and host-managed SMR, which is used in high-capacity data center applications. Each implementation serves a different use case, ranging from personal computing to some of the largest data centers in the world. Recently, there has been a discussion regarding the recording technology used in some of our WD Red hard disk drives (HDDs). We regret any misunderstanding and want to take a few minutes to discuss the drives and provide some additional information. If you are encountering performance that is not what you expected, please consider our products designed for intensive workloads. These may include our WD Red Pro or WD Gold drives, or perhaps an Ultrastar drive. Our customer care team is ready to help and can also determine which product might be best for you.
WD Red Better Together To Power Your NAS | SCAN UK
WD Red HDDs have for many years reliably powered home and small business NAS systems around the world and have been consistently validated by major NAS manufacturers. Having built this reputation, we understand that, at times, our drives may be used in system workloads far exceeding their intended uses. Additionally, some of you have recently shared that in certain, more data intensive, continuous read/write use cases, the WD Red HDD-powered NAS systems are not performing as you would expect. WD Red Plus is the new name for conventional magnetic recording (CMR)-based NAS drives in the WD Red family, including all capacities from 1TB to 14TB. These will be the choice for those whose applications require more write-intensive SMB workloads such as ZFS. WD Red Plus in 2TB, 3TB, 4TB and 6TB capacities will be available soon. Unfortunately for Western Digital, NAS users tend to be significantly more technical than general consumers—and they frequently hit their disks with far more difficult workloads than Western Digital apparently tested or planned for. From Red to Red PlusOur current device-managed shingled magnetic recording (DMSMR) (2TB, 3TB, 4TB, and 6TB) WD Red series will be the choice for the majority of NAS owners whose demands are lighter SOHO workloads. In (very) brief, SMR disks generally perform well enough in light storage workloads, with plenty of idle time between storage requests—but they can fall catastrophically flat on their faces when hit with more demanding workloads. The ZFS filesystem, in particular, tends to present SMR disks with challenges they have difficulty handling. Due to the fact that the range of use cases for NAS has become increasingly diverse, we are now making it easier for users to match the right drive with their applications and workloads – from moderate small office/home office (SOHO) workloads to intensive small- and medium-business (SMB) use, as well as more demanding environments.

Further Reading Lawsuit vs. Western Digital wants to end any use of SMR in NAS drivesWe're not certain whether the new, easier branding will satisfy the already-ongoing lawsuits against Western Digital, however. One US class-action lawsuit alleges that marketing any SMR disk as "NAS" disks amounts to actionable false advertising. The new branding is a big help to consumers who already know what SMR means and what its limitations are—but it's unlikely to do much to educate consumers who aren't already in the know. From a sequential performance perspective, our tests confirm that our WD Red DMSMR drives are on par with our existing CMR drives. Third-party testing also validates the performance of WD Red DMSMR drives compared with other drives under general hard drive benchmarks used in an NAS environment. We’re committed to providing the information that can help make an informed buying decision for as many uses as possible. Thank you for letting us know how we can do better. We will update our marketing materials, as well as provide more information about SMR technology, including benchmarks and ideal use cases.Ideal para sistemas NAS para home offices, usuários avançados, pequenas e médias empresas e sistemas e concumidor/comercial We typically specify the designed-for use cases and performance parameters and don’t always talk about what’s under the hood. One of those innovations is Shingled Magnetic Recording (SMR) technology. There's also a Red Pro line targeted to maximum-performance applications. This line is unchanged—it existed with the same branding before the SMR fiasco, and it still exists with the same branding and same models today. Understanding SMR limitations
