WD Red 6TB 3.5 Inch NAS Internal Hard Drive - 5400 RPM - WD60EFRX

Product Information

The thing I don't understand is that SMR is suppose to help increase density on large drives. I would think the 8+ TB Drives would be using this NOT 1-6TB Drives. Are you sure that WD hasn't changed the small Purple drives to SMR? These prices are almost the same as the WD Blue SMR drives. For those googling for the answer whether combining WD EFRX and WDEFZX (WD40EFRX and WD40EFZX in my case) would be safe. SMR does result in lower performance, but it enables cost savings that are attractive to some users, and if used in the correct types of workloads, those savings are worth the exchange of gaining access to deeper capacity. However, using SMR tech for desktop and laptop boot drives will likely remain a topic open for debate, as their underwhelming performance in sustained random write workloads could hamper performance in standard operating systems. WD Red hard drives and SSDs have been compatibility-tested by major NAS system providers with their NAS systems and components.

I've been attempting to upgrade two 2-Bay NAS drives from 3TB drives to 6TB drives in RAID 1 configuration. Previously I've used Seagate drives but having seen good things written about WD I though I'd try the WD Red 6TB drives which are compatible with my NAS enclosures. Use this modified string, for example "HUH7280??ALE60?" to search for model name in the tables below. Any capacity drive is from the same family as the found model name and all the fields from the found table row are valid for it, meaning HUH728060ALE601(6TB) and HUH728080ALE600(8TB) are from the same family. It's because any given amount of storage they sell is going to be cheaper to make with SMR as opposed to CMR, regardless if it's 1TB or 8TB, because less material is needed to manufacture it.

Thank you!

Shingled Magnetic Recording (SMR) technology helps hard drive manufacturers to produce HDDs with larger capacity. The thing i'm pointing out is the characteristics of the EFAX and EFRX seem to be very different - at least in a in a QNAP NAS and you probably shouldnt mix them if you can avoid it. Confidently upgrade your NAS performance with the assurance of a 3-year limited warranty, coupled with world-class support services included with every WD Red™ drive.

Few of them are SMR and other are CMR drives. You can identify them here https://nascompares.com/answer/list-of-wd-cmr-and-smr-hard-drives-hdd/ Im at a bit of a crossroads here and was hoping for some advice. Right now there is only about 3tb of data on the entire nas while it reshapes. But i had about 5tb more ready to load onto the nas soon as it was going to complete. My initial thought was to buy another older WD60EFRX and soon as the raid reshape was completed I would pull the newer SMR drive and put in the WD60EFRX and let the system repair. 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. The 3.5-inch form factor ensures easy integration into desktop setups, delivering reliable performance, ample storage space, and seamless compatibility. They are built to withstand a lot of wear and tear, making them a good choice for long-term storage. RPM: I'm using Raid 5 I'm a little under half full at about 8TB and get about 75MB/s read 55MB/s write on a video file copy which is well under the theoretical throughput (125MB/s) of Gigabit Ethernet.Reliability: Desktop drives aren’t typically designed for the demands of an always-on NAS environment. WD Red hard drives are designed to perform under tough conditions encountered in high-intensity 24x7 multi-user NAS environments. Ideal for Home Offices, Power Users, Small to Medium Businesses and Consumer/Commercial NAS systems They really aren't, see viewtopic.php?f=45&t=154346 What a scam.Well that explain the slowness and inconsistency.
