Western Digital 24TB WD Red Pro NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, CMR, 512 MB Cache, 3.5" - WD240KFGX

I learned the hard way that putting a random collection of disk drives in my Drobo (different speeds, different capacities, and different brands) did not work well. The Drobo would be slow and have poor storage utilization. Ideally what's needed is disks of the same capacity, speed, and designed for NAS use. These WD Red Plus drives are a good compromise between capacity, speed, and price. The rotation speed is either 5400 or 5600 depending on the age of the drives. The reliability of the drives in my 5 slot Drobo has been exemplary. I had my first failure in years and was able to pop out the failed drive and put in a new one with no loss in access to my data. The Drobo is obsolete and if it stops working I'll have to replace it with a new disk array. I'd still use the WD Red Plus drives based on my good experience with them.

Box was a little damaged so i suggest you ask for amazon to package it with their packaging also but drive arrived in perfect condition checked its stats everything indicated newbeen running it for a week it is very quiet and plenty fast for my use case

Anyone that has a server with lots of data needs these drives. I have converted all of my VHS & VHS-C tapes to Digital format. I have 3 of these drives in my video server.

Had my hard-drive in my NVR crash. This went right in and formatted. All seams good.

Drive APPEARS to be USED but was sold as NEW.I've been buying WD HDD's since 1993 and have since talked to many WD employees on the phone. They've said that from the factory all HDD's are packed in anti-static bags with their logo on the bag and a very distinctive clean and straight heat seal mark. They also used to include a desiccant pouch in the bag to ensure any moisture that may have gotten in was absorbed, currently though they're not included. Also they have rules on how they must and must not be packaged for shipment. Amazon, as seller and shipper, have always packaged HDD's as per Western Digitals specifications. The sellers to be wary of, are Marketplace sellers.I started computing in 1983 with a Commodore 64. Back then I was in the United States Navy and for a time attached to the Aviation Intermediate Maintenance Department (AIMD) which supported The multi-million dollar aircraft 'Lockheed Orion P3C update 2&3'. I talked to Electronics Technicians (ET's) in the Micro-Min shop where they removed and replaced chips on Printed Circuit Boards (PCB's) and was made aware of ESD which today stands for Electrostatic-Discharge, but many of the Techs used 'Electrostatic Sensitive Device' for the acronym, which is just as true. As it turns out some chips, CMOS and smaller tech devices, can be destroyed by static electricity much lower in voltage/amperage than can be felt by humans walking across a carpet in the winter and touching a door knob and other such situations, so less than a human can sense. Which is why all HDD's are shipped from the factory in anti-static bags, because touching the drives PCB or the electrical connection pins could damage the drive. This is actually true of all computer components.This is an edit:You should always use a proper ESD safe wrist-strap when handling any computer component. You attach it to ground and should have jumper wires attached to all component grounding areas that you are currently working on. This is to ensure that all grounds are at the same electrical potential. Only handle cards (PCB's) on the edge, never on the contacts. Never touch any of the semiconductors on the PCB. Most modern HDD's have a relatively thin top made of stainless steel that has been stamped out of sheet SS with dented areas so as to make it more rigid. But you still don't want to handle them in that area. The infamous 'click of death' is due to unequal torqued pressure on the screws that afix the top to the cast/milled main body. The cast metal portion is the only portion that you should ever handle during installation whether it be a case drive bay or a quick release sled (docking bay). Apparently you can buy a mini torque device to re-torque the screws to the proper value, however note that the specification can change between different manufactures and models. So it's best not to not chance disturbing the torqued value from the factory.I only ever touch the cast portions (sides) of the drives, and have never had any problems with WD Drives, accept for a few DOA's that just wouldn't run. I've never had a clicking drive. I've been buying WD drives Exclusively since 1994. To give you an example of how many drives I've purchased, I have 15 computers running daily and 4 are either multi drive NAS's or NAS backups. Even though modern drives park the heads during shut down they should always be handled with kid-gloves, especially don't bump the case while the computer is running, though their arms are relatively stiff, the 'flying' heads can be made to impact the disks thus creating HARD errors on the surface. You'll probably never recover that data.Everyone building computers must be made aware of these facts, because manufacturers should not end up responsible for the mistakes of computer builders due to ignorance. It can only serve to drive up prices for their products and the cost to Amazon for logistics pertaining to unnecessary returns. Not to mention the down time of the builders awaiting a replacement part.I use these facts to ensure a HDD is in fact New and undamaged.The drive in question, that I'm reviewing, came in a generic Anti-Static bag and was sealed by a cheap heat sealer. The question everyone must ask themselves, that believe in data security, accuracy and reliability and their warranty, is: "why would anyone remove a HDD from it's original factory anti-static bag, then buy a generic anti-static bag and a cheap heat-sealer, then re-package it and sell it as NEW?" While these facts don't necessarily mean conclusively that the drive is used, one has to wonder why anyone would do all that. Probability? Possibility? Who want's to be sure? I would say a smart buyer would.I returned this drive to the seller, which cost me time, fuel and unnecessary wear and tear on my vehicle. Not to mention the cost to Amazon and the seller. Sellers have to remain honest!I bought this drive from "ALL4COMPUTERS," The UPS RETURN "proof of delivery" page said returned to "RESIDENTIAL".As I'm sure, everyone wants to get what they pay for. And no one likes scams or people that will try and cheat them. Always ensure that you are indeed getting NEW products when in fact that is what you've been told they are. As if not sure, you could end up as an ignorant loser.Ignorant: MW Definition: "lacking knowledge or comprehension of the thing specified". It's not derogatory as some believe. I'm ignorant of a great many things. Knowledge is power, so seek it and you shall learn and never be fooled again.Of course these facts are only being said for those that are unaware, for those 'in-the-know', ignore all the above advice. And please don't be offended, this has been for all those that are affected.

I have a home NAS that is filled with WD RED drives. I wanted to expand the capacity, so I was replacing a 1TB drive, with this 4TB drive. Unfortunately, even with much time spend with support, I could not get my Synology NAS to recognize this drive. The belief was that the drive was not working. So I returned it (and purchased again. that drive did work as expected, right away). So I did just happen to receive a flawed drive.Would I purchase again: YesWould I recommend to others: Yes

I love WD reds. I have this in my server and has been running 24/7 since I bought it over 2 years ago. Still reliable. If you have a home server, I would definitely recommend these, or any WD Red drives.

I replaced the failed hard drive in my TiVo Roamio ota after 13 years of operation. This new drive works great, but I had to upgrade the TiVo’s 12v 2a original power supply with a new 12v 3a power supply because of the new drive’s power requirements.
