Western Digital Red HDD 3000GB Serial ATA III internal hard drive Red, 3.5", 3000 GB, 5400 RPM, Serial ATA III, 64 MB, HDD

Product Information

Perpendicular magnetic recording (PMR) and shingled magnetic recording (SMR) are technologies used to physically store bits of data onto a hard disk drive (HDD). For HDD manufacturers, one of the most important concerns is areal density, which is the number of bits of data that can be recorded onto a magnetic disk. Areal density is measured by the number of bits or gigabits per square inch, with the higher values allowing for greater storage using the same amount of disk space. SMR offers larger drive capacity than the traditional PMR because SMR technology achieves greater areal density. It is important to choose a drive purpose-built for RAID-optimized NAS systems to ensure optimum performance and preserve your valuable data. Take the following into consideration when choosing a hard drive for your NAS:

If you connect by example 10 SSD, you will be near to load 6G/s * 10 = 60Gb/s = 7.5 GB/s (very theorically, but maybe reach the PCH bus limit ?)

We also measured the power consumption of each Synology model filled with Western Digital Red hard drives through our Eaton Advanced Monitored ePDU, which monitors devices at the outlet level. The eight-bay Synology DS1812+ used 59 watts during active write activity and 55 watts at idle, while the five-bay DS1512+ used 49 watts under load and 44 watts at idle, while the small two-bay DS712+ needed just 31 watts under load and 24 watts at idle. Western Digital had a simple goal in mind when launching the WD Red; they wanted the drives to be synonymous with SOHO NAS use, developing into the defacto standard for small NAS use. Their custom firmware dubbed NASware and related technologies get the WD Red ready for this specialized 24/7 operational task. The Red has all the features needed like no unnecessary head parking, drive tolerances that support RAID environments and3D Active Balance technology which reduces vibrational wear on the drives. WD has also pre-qualified the Red with leading NAS vendors and the host controllers found in most NAS systems. On the support side the drives come with a three year warranty and a dedicated support line just for WD Red owners. The WD Red comes in 1TB, 2TB and 3TB capacities with 64MB cache, SATA 6Gb/s interface and Intellipower low power spindle. For data migration Western Digital has included a copy of Acronis True Image software. WD offers a three year warranty, dedicated support line and QR code on the drive for mobile access to product documentation and support.

Western Digital Red WD30EFRX 3000GB, 3.5", 6.0 Gbps, IntelliPower, Network Attached Storage, Serial ATA Hard Disk Drive - Brand New

As an industry-leading hard drive manufacturer, Western Digital stands behind their NAS storage solutions with the assurance of a 3-year limited warranty and world-class support services for hassle free data storage. It’s an interesting decision – WD is expanding their low-power 3.5" hard drive offerings with a second line at the same time Seagate exits the "green" market, claiming low-power drives aren’t really all that beneficial or quite frankly, special. The Western Digital Red family of hard drives is designed for the 1 to 6 bay SOHO NAS space, which is about as specialized as it gets. WD has several features that they’re touting as critical for the NAS user including; NASware specialized firmware, Intellipower low power spindle, robust NAS compatibility list, three year warranty and a dedicated WD Red 24×7 customer support line (1-855-55-WDRED if you need them).The obvious question may be then, what’s wrong with the WD Greens and other low power drives that have been performing NAS duty to this point? The answer is really about projected use. The WD Green for instance, while the leading low power drive on the market, wasn’t designed for the 24×7 access requirements that NAS systems require. The WD Red was engineered specifically for this duty, complete with customized NASware firmware which includes critical features like intelligent error recovery controls that prevent drives from dropping off the RAID due to long recovery cycles. The drives also are engineered with "3D Active Balance technology" which tunes the drive to eliminate vibration leading to improved reliability and overall performance.

NASware™ grows to 3.0 - Built off of our determination to deliver the best NAS experience, NASware 3.0 extends our promise by further optimizing WD Red for the NAS environment with added support for 6 to 8 NAS bays. WD Red now supports small NAS systems from 1 to 8 bays thanks to NASware 3.0, which further improves drive compatibility and reliability. At 48 TB of total capacity in an 8 bay system, WD Red expands your NAS experience. Professional solutions - Designed specifically with SMB customers in mind, the WD Red family has expanded with the addition of WD Red Pro, which is available for the 8 to 16 bay medium to large-scale NAS environments. With capacities from 2 to 4 TB, The Western Digital Red 3TB drive uses a primarily single-sided PCB, with all components facing the body of the drive for thermal dissipation. The board is held firmly to the drive with four Torx screws with a vibration isolation/thermal pad mounted between the circuit board and metal body.

WD Red is designed specifically for NAS systems that have 1 to 8 drive bays in both 3.5-inch and 2.5-inch form factors. The drives are designed and extensively tested for compatibility in the unique 24x7 operating environment and for the demanding system requirements of home and small office NAS.

Available in capacities ranging from 1TB to 8TB, WD Red is designed specifically for home and small office NAS systems. The drives are extensively tested for compatibility and reliability in the demanding operating environment of a 24x7 NAS system. WD's exclusive NASware™ firmware technology enables seamless integration and balanced performance. Innovative technology reduces power comsumption and lowers the operating temperature, and with a 35% improvement in MTBF over desktop drives, WD Red is a more reliable and robust NAS hard drive solution.The first indicator to detect whether it is a SMR drive is the cache size. But do look for letters EFAX in the serial number this would mean SMR. Old drives (WDx0EFRX) had 64MB cache whereas new replaced drives (WDx0EFAX) feature 256MB. You can also read the serial number on the disk itself and compare it to a table bellow. But the PCH link to CPU are done with a DMI 2.0 that if i understand correctly use like a PCIe x4 2.0 bus (or something near) PS: Even with a 12 SSD pools it's hard to handle more than 2GB/s READ/WRITE throughtput within a ZFS Pool, so it can be enough for your pool. Lower operating temperatures - Innovative technology reduces power consumption and lowers the operating temperature, resulting in a more reliable and affordable solution for always on NAS environments. From the front the 3TB Red has a standard SATA data and power connection with 8 service pins generally reserved for debugging modes and changing drive settings for advanced users.
