Faulty brand new drives are not a good sign

I purchased six of these drives to fill out a QNAP NAS extender. Four drives were sent in the first batch with two DOA. Got replacements which were not double packed when they were sent out of which one was failed. Trying to get those replaced. The other two drives I received had one faulty one so I'm working to get those replaced. Support was slow in addressing. I had to escalate a few times to get any action. The drives that do work I haven't had any problems. They are seem to be more silent than IronWolf Pros. Despite that I fear for my data. It was the price that attracted me to these drives. Foolish me.

20 TB Red Pro's on NAS

Replaced a 2 TB desktop storage with a small NAS and a pair of these 20 TB Red Pro's. Amazing to get this many terabytes on a drive.

Who would not expect 5-star quality from WDC.

I keep coming back to WDC for their mechanical NAS drives, their Quality & Performance create Value for their internal HDD's.

Wow!

I purchased multiple WD drives for my NAS, and unfortunately, one of them was faulty. However, my interaction with customer support was a very positive. They were highly responsive and supportive in assisting me to find a solution. The drives are quiet and fast - perfect for my new NAS.

RMA - Customer Service

Purchased 4 WD Red Pro NAS drives for MyCloud Pro. 1 of the drives out of the box wouldn't load. Easy replacement, right? No.....WD process was not clear and it took 2 weeks to get an RMA approved (even though I sent the damaged drive back and received in 3 days). Terrible customer service. I couldn't fire up the new MyCloud and delayed my project for 2.5 weeks.....unreal. 1 WD rep told me it's faster to purchase another drive instead of going RMA. Clean up the DOA for your customers---they should have priority!

Why no discounts in the EU?

The drives are good, but why are there never any discounts within the European Union? It always seem to be some kind of discounts within the USA, but in the EU there are never any Black Friday deals, Winter Deals, Student Deals, Senior Deals, nothing. Never. Ever.

Drive arrived dead straight from WD.

The drive came in dead. I contacted support, they told me it was out of warranty. It was less than 3 weeks from the time of purchase straight from Western Digital. I just wanted a replacement drive. How could a brand new drive that has only been available for about 1 year, and has a 5 year warranty, be out of warranty? Make it make sense.

So far so good

Easy install and setup and are working well enough thus far. Recommend buying it through Western Digital than through Amazon as the sellers manipulate the base price.

No such thing as a free lunch

Endurance of this hard drive is appalling. It is as bad as cheap QLC NVMe SSD, which makes it useless as backup and storage solutions. 300TB/yr is just too little to meet regular usage of this so called high grade hardware. No wonder it was so cheap.

Great Deal, Wonderful Drive, Well Worth It

Hey I got 2 x 20TB drives cheap, and they arrived quickly. I have filled both drives up already and already need 2 more. So far these drives have held up to hours of use as they are in my home theater Zappitti players and being accessed for up to 8 hours at a time constantly.

Installed four of these into a Ugreen NAS 4800 Plus. No issues so far.

Because enterprise environments demand robust and reliable storage solutions, the WD Red Pro 3.5" SATA III Internal NAS Hard Drive is engineered to meet these high standards. Specifically designed for commercial and enterprise NAS systems, this hard drive excels in handling high-intensity workloads in 24x7 multi-user settings. The WD Red Pro series is synonymous with performance, scalability, and dependability, making it an ideal choice for businesses that need to store, share, and collaborate on large volumes of data within multi-bay RAID-optimized NAS systems.

Optimized for NAS environments, the WD Red Pro features Western Digital's exclusive NASware technology. This innovation fine-tunes drive parameters to align with NAS system workloads, enhancing both performance and reliability. The inclusion of Rotation Vibration (RV) sensors is a testament to its advanced engineering, as these sensors proactively counteract disturbances from excessive vibration, ensuring minimal turbulence and sustained performance.

Designed for continuous operation, the WD Red Pro hard drives are built to withstand the rigorous demands of high-intensity, always-on NAS environments, thereby increasing system durability. The drives are equipped with a multi-axis shock sensor that detects subtle shock events and compensates with dynamic fly height technology, offering additional protection within NAS enclosures.

Compatibility is a key feature of the WD Red Pro series. Western Digital collaborates with a wide range of NAS system vendors to conduct extensive testing, ensuring dependable compatibility with most NAS enclosures. This hard drive is engineered with industry-leading technology, including Western Digital's proprietary OptiNAND technology. This technology leverages integrated iNAND embedded flash to perform essential housekeeping functions, freeing up capacity and enhancing overall drive performance.

When comparing desktop drives to the WD Red Pro, it's crucial to choose a drive purpose-built for RAID-optimized NAS systems to ensure optimal performance and data preservation. Unlike desktop drives, which are not typically designed for the demands of an always-on NAS environment, WD Red Pro hard drives are tailored to perform under the tough conditions of high-intensity, 24x7 multi-user NAS environments. They are RAID-ready, featuring RAID error recovery control to help reduce failures within multi-bay NAS systems. Additionally, while desktop drives often lack protection from noise and vibration, WD Red Pro drives include RV sensors to mitigate these issues, making them a superior choice for multi-bay NAS systems.

WD Red Pro 20TB Features

  • Ideal for creative pros, medium to large businesses, and commercial/enterprise NAS systems
  • For RAID-optimized NAS systems with an unlimited number of bays
  • Rated for 550TB/year workloads and up to 2.5M hours MTBF

Key Features

  • Store vast amounts of data with the 20TB capacity, perfect for extensive media libraries and backups.
  • Experience reliable performance with a 7200 RPM spin speed, ensuring quick access to your files.
  • Benefit from SATA III interface for fast data transfer rates, ideal for demanding NAS environments.
  • Trust the WD Red Pro series, designed for 24/7 operation in multi-bay NAS systems.
