Your California Privacy Rights | Do Not Sell My Personal Information WD RED: 3TB, 3TB, 3TB, 4TB = Oude situatie zonder SMR disks WD RED: 3TB, 4TB, 6TB, 6TB = Nieuwe situatie waarbij de 6TB disks SMR zijn Momenteel ben ik aan het mailen met de verkopende partij maar de communicatie vlot niet echt, iedere dag maar één mailtje hooguit terug. 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. 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 regret any misunderstanding and want to take a few minutes to discuss the drives and provide some additional information. SMR / CMR technology This hard disk uses SMR technology and can therefore have disadvantages in certain RAID scenarios. As we mention on our last podcast, several users were frustrated to find that WD Red NAS drives they purchased were SMR when they thought they were CMR. We’ve rigorously tested this type of use and have been validated by the major NAS providers. Join the Ars Orbital Transmission mailing list to get weekly updates delivered to your inbox. The EFAX Red is 68.8 percent slower on average to return from an operation than the Ironwolf—but again, this is "not winning the race" territory, not "you're going to get sued for fraud" territory. • 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. 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. We are continuously innovating to advance it. Sign up or login to join the discussions!

This is the revision of firmware that came on both of our drives. This results in extremely low average throughput (compared with the drive’s available throughput) and provides plenty of idle time for the DMSMR drive to perform the necessary background operations, making it an ideal fit for this application. Voor die laatste fabrikant komt nu een nieuwe stap in de soap, want NAS-fabrikant Synology noemt de WD Red-hdd's nu incompatibel met zijn apparaten. We continue engaging customers and partners and analyzing real-world data to offer a family of WD Red NAS drives – from HDDs to SSDs – that serve all workloads and applications. - Jun 5, 2020 9:40 pm UTC. 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. WD Red Plus in 2TB, 3TB, 4TB and 6TB capacities will be available soon. The use of SMR technology in Western Digital Red is not going away—but moving forward, "Red" will exclusively mean SMR disks. Even retesting it a second time, when the firmware has a harder job dealing with already-full zones, doesn't change the picture significantly. CNMN Collection WD, Seagate i Toshiba po cichu wciskają wolne dyski SMR jako NAS i desktop. Eind mei ontdekten we dat Western Digital is aangeklaagd omdat het zijn smr-techniek in harde schijven voor onder meer nas-producten gebruikte zonder dit in de productinformatie te zetten.Ars Technica heeft Western Digitals Red-hdd's op de proef gesteld, om te kijken hoe groot de prestatie-impact precies is. © 2021 Western Digital Corporation or its affiliates. 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 With drives up to 6TB, WD Red™ offers a wide array of storage for customers looking to build a NAS solution. SMR is a technology that can introduce more capacity onto a platter, as well as introduces performance differences, particularly in writes. Now photographer Joseph DiGiovanna's project will capture the city over 30 years. Thank you for letting us know how we can do better. Its effect on storage is somewhat of a paradox. We tested WD Red SMR v CMR drives to see if there was indeed a significant impact with the change. Western Digital has heralded a positive shift in its approach to users of shingled WD Red NAS drives, via a short statement on the company blog.. As described in our recent article Western Digital admits 2TB-6TB WD Red NAS drives use shingled magnetic recording (SMR), some users can experience performance problems in situations such as adding the drives to RAID groups which use … From a sequential performance perspective, our tests confirm that our WD Red DMSMR drives are on par with our existing CMR drives. iXsystems and Western Digital have been working to identify and resolve the ZFS compatibility issue with the WD Red DM-SMR drives. Er is een toonaangevende WD RedTM-schijf voor elk compatibel NAS-systeem waarmee je je waardevolle data kunt opslaan. We used many red efrx with no problem in the years. To get a better handle on the situation, Ars purchased a Western Digital 4TB Red EFAX model SMR drive and put it to the test ourselves. Western Digital lässt trotz berechtigter Kritik nicht davon ab, die SMR-Technik in seinen NAS-Festplatten der Serie WD Red einzusetzen. © 2021 Condé Nast. New WD RED EFAX with SMR are orrible (to evitate). Red PLUS en … iXsystems and Western Digital have been working to identify and resolve the ZFS compatibility issue with the WD Red DM-SMR drives. This has rightfully raised questions as to what Western Digital was thinking when it tried to use SMR technology in NAS drives at all, let alone trying to sneak it into the market. We can extrapolate from this peak latency result that when the Red's firmware is floundering badly, its throughput may fall below 1MiB/sec for a little while—and this correlates with the ever-changing throughput numbers we saw as we watched the throughput tests running. This blog includes news across the Western Digital® portfolio including: G-Technology, SanDisk, WD and Western Digital. Here is that list of our client internal HDDs available through the channel: Click here for SKUs to our client internal HDDs using SMR technology. In addition to taking customer and partner feedback seriously, we conduct in-house testing on the WD Red family of drives for compatibility, performance, endurance and other factors. Listed below: ST8000VX002 ST8000VX008 SMR ST6000VX011 ST6000V… WD Red 8TB-14TB are CMR-based." Availability.

WD will continue shipping the 2 to 6TB WD Red drives with DM-SMR (Drive-Managed SMR) for less-demanding SOHO users, with the existing CMR … There was no fanfare or press-release, and the … Ars may earn compensation on sales from links on this site. CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS: This website may contain forward-looking statements, including statements relating to expectations for our product portfolio, the market for our products, product development efforts, and the capacities, capabilities and applications of our products. The data intensity of typical small business/home NAS workloads is intermittent, leaving sufficient idle time for DMSMR drives to perform background data management tasks as needed and continue an optimal performance experience for users. While we work with iXsystems on DMSMR solutions for lower-workload ZFS customers, we currently recommend our CMR-based WD Red drives, including WD Red Pro and the forthcoming WD Red Plus. The past week has been eventful, to say the least. 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. WD Red, WD Red PLUS en WD Red PRO. Dus dit kan nog wel even gaan duren. Having built this reputation, we understand that, at times, our drives may be used in system workloads far exceeding their intended uses. Throughput and idle time are key considerations in these types of SOHO workloads. When adding a DM-SMR drive to a ZFS pool, it is better that the drive is erased beforehand. 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 … Also all WD drives that are SMR to this point have claimed TRIM support. The affected HDD (hard disk drive) models are: 3.5″ WD Red … We will have options for you. You must login or create an account to comment. All rights reserved. There’s a leading edge WD Red™ drive for every compatible NAS system to store your precious data. 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. Hight noise when they aren’t working (I don’t konw what they do in that time) . 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). We typically specify the designed-for use cases and performance parameters and don’t always talk about what’s under the hood. When we drill down a little farther and look at fio's latency numbers, things look noticeably worse. While test results can vary from one methodology and test bed to the next, we acknowledge that in some cases DMSMR, for the idle-time reasons covered earlier, can result in slower rebuild times. Western Digital initially denied the secret switch, but after public pressure had no choice but to finally admit what they had done. They are great for sharing and backing up files using one to eight drive bays and for a workload rate of 180 TB a year. Jim Salter Western Digital has not commented on the situation, but it continues to sell SMR WD Red drives into this space. So I don't believe these are SMR. The testing is not yet complete, but at this stage, we can confirm: Some SMR drives are indeed compatible with ZFS, though due to a lack of a ratified industry standard implementation of the technology, they don’t all necessarily behave the same. “Currently, Western Digital’s WD Red 2TB-6TB drives are device-managed SMR (DMSMR). If your drive is not found in this guide, please send me pictures from both, the label and the PCB sides of the HDD (or full model and serial number if you cannot take the pictures) and I'll try to add your drive to the guide. Western Digital has been receiving a storm of bad press—and even lawsuits—concerning their attempt to sneak SMR disk technology into their "Red" line of NAS disks. Hight noise when they aren’t working (I don’t konw what they do in that time) . Then once it had finished rebuilding, we failed it out again, wipefs -a'd the RAID header from it, and added it back in to rebuild a second time. • Our WD Red Pro (CMR 2TB to 18TB) series for the highest-intensity usage remains the same. WD Red Pro (2020) vanaf € 87,89. Here’s a breakdown of our products for NAS use-cases: • Our 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. a) WD isn’t clearly marking these as SMR based drives, even if they are “drive managed” meaning the OS doesn’t need to get involved b) this product (WD Reds) is meant for use in RAID arrays where during silvering there is a lot of not-quite-sequential writing going on. Had Western Digital even tested the disks at all? We will have options for you. When we created the RAID6 array, we used the argument -b none, to keep it from attempting to perform a bitmap scan to do faster rebuilds when using a disk that had previously been in the array. 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. If you want a hard drive with CMR technology, you will need to purchase a WD Red … WD has responded through its blog, stating mainly that only certain SKUs of the WD Red were … Recently, the well-known tech enthusiast site Servethehome tested one of the SMR-based 4TB Red disks with ZFS and found it sorely lacking. June 2, 2020, 1:29pm #11. Western Digital 2TB-6TB WD Red NAS are using SMR, an issue with NAS RAID? In de praktijk rapporteerden klanten dat de Red-drives ongeschikt zijn om een RAID-configuratie herop te bouwen omwille van de stiekeme implementatie van SMR. Neither the WD120EMFZ or WD120EMAZ drives I own support TRIM. The WD Red DM-SMR drives use an indirect Logical Block Addressing model, which is similar to SSDs. We weren't surprised that the SMR disk performed adequately in the first test—consumer ire aside, it seemed unlikely Western Digital had sent these disks out the door with no testing whatsoever.
