WD Red 제품군 이외에 WD Red Pro, WD Blue, WD Black, WD Purple 제품군도 모두 같이 공개가 됐습니다. The past week has been eventful, to say the least. Western Digital Addresses the WD Red SMR Controversy In the wake of media coverage from the likes of Ars Technica on the subject, Western Digital has provided marcolopes. SMR is tested and proven technology that enables us to keep up with the growing volume of data for personal and business use. Perhaps they intend on replacing the 12TB easystores with SMR drives eventually. So I don't believe these are SMR. TDMR - Two-Dimentional Magnetic … Checking the latency of the individual returns is a bit more informative—but still, in terms of, with 89 posters participating, including story author, I updated my crusty old Pentium G-based server—the results are worth sharing. But as valuable as Servethehome's ZFS tests were, they ignored the most common use case of this class of drive—consumer and small business NAS devices, such as Synology's DS1819+ or Netgear's ReadyNAS RN628X00. As explained in our post on DMSMR, as well as in media reviews, these drives prefer idle time to perform background operations, without which the drive may take longer to complete a command. We want to thank our customers and partners for your feedback on our WD Red family of network attached storage (NAS) hard drives. WD zondigde in zijn WD Red-portfolio, dat gericht is op NAS-toepassingen en voor een meerprijs verkocht wordt in ruil voor extra betrouwbaarheid. SMR is a technology that can introduce more capacity onto a platter, as well as introduces performance differences, particularly in writes. Currently, Western Digital’s WD Red 2TB-6TB drives are device-managed SMR (DMSMR). The increased amount of sustained random writes during ZFS resilvering (similar to a rebuild) causes a lack of idle time for DMSMR drives to execute internal data management tasks, resulting in significantly lower performance reported by users. Now photographer Joseph DiGiovanna's project will capture the city over 30 years. Western Digital has been hit by a class-action lawsuit over alleged false advertising over some of its WD Red hard drives featuring undocumented DM-SMR (drive-managed shingled magnetic recording), a physical layer data writing technique that maximizes capacity at heavy costs of random write performance, that effectively render the drives unfit for RAID applications that are common with NAS … As a leader in HDD and flash technologies, we are committed to addressing the evolving needs of our customers and to offering the right technology for each implementation. These will be the choice for those whose applications require more write-intensive SMB workloads such as ZFS. 絶対にWD Redを使うべき? 個人でNASを構築するときに迷うのがHDD選び。「NAS用にはWD Red一択!」とよく聞くけど、これってWD Blueではダメなのでしょうか。そんなNASおすすめのHDD問題をスペック比較で考えてみます。 RAID 1だったら、WD Blueでもいいんじゃないかなって思ったりしない! WD Red SMR v. CMR Part I: The Reasonably Similar. This gave us our two test cases—a factory-new Red SMR disk being rebuilt into an array, and a used Red SMR disk with a lot of data on it already being rebuilt into an array. Bekijk alle interne harde schijven. The controversy of Western Digital shipping SMR WD Red drives came to light when Alan Brown, a network administrator with the UCL Mullard Space Science Laboratory, noticed that a brand new WD Red HDD kept getting kicked out of RAID arrays during resilvering (rebalancing of data with the addition of a new disk to an existing RAID array). iXsystems and Western Digital have been working to identify and resolve the ZFS compatibility issue with the WD Red DM-SMR drives. New WD RED EFAX with SMR are orrible (to evitate). Our customer care team is ready to help and can also determine which product might be best for you. Western Digital published a blog earlier this week that suggests users who are experiencing problems with their WD Red NAS SMR drives may be over-using the devices.

We regret any misunderstanding and want to take a few minutes to discuss the drives and provide some additional information. The next thing to check on was whether the EFAX would handle a heavy version of the typical day-to-day use case of a consumer NAS well—that is, storing large files. We did not experience this failure mode, and … WD has responded through its blog, stating mainly that only certain SKUs of the WD Red were affected. According to iXsystems, WD Red SMR drives running firmware revision 82.00A82 can cause the drive to enter a failed state during heavy loads using ZFS. Western Digital lässt trotz berechtigter Kritik nicht davon ab, die SMR-Technik in seinen NAS-Festplatten der Serie WD Red einzusetzen. Once the Ironwolf had successfully rebuilt into the array, we failed it out again—and this time, we removed it from the system entirely and replaced it with our 4TB Red SMR guinea-pig. 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. Hight noise when they aren’t working (I don’t konw what they do in that time) . Western Digital の WD Red シリーズでSMRとCMRが混在して販売されていることが判明しました。 NAS向けHDD「WD Red」の記録方式をこっそり変更した件についてWDが釈明 – GIGAZINE. It's only when we look at peak latency from the 1MiB random write test that we begin to see how bad things can get when you push the Red in unplanned-for directions.

We’d mention other brands, but at this time only Western Digital and Seagate make drives of this capacity. When the WD Red problem first broke, multiple NAS RAID users said they were unable to integrate an SMR drive into a RAID array built with CMR disks due to performance problems and excessive timeouts. In a RAID rebuild scenario using a typical Synology or QNAP (non-ZFS) platform, WD Red DMSMR drives perform as well as CMR drives or show slightly longer RAID rebuild times, depending on the condition of the drive and extent of rebuild required. Your concerns were heard loud and clear. SMR / CMR technology This hard disk uses SMR technology and can therefore have disadvantages in certain RAID scenarios.
