Western Digital WD4000FYYZ ENTERPRISE 4TB 7200RPM 64MB Cache SATA 6.0Gb/s 3.5 internal hard drive

These drives are being hawked all over the place but most are used and at EOL (end of life) service conditions. They may have even started to fail.No so with the one I received.Pros:S.M.A.R.T. status showed zero power-on hours and no defects after the first long SMART test.These are - in-fact - brand new drives from "old" stock.This same drive WD4000FYYZ was picked over the WD Black series for gaming and high data throughput applications by several notable reviewers. It even has the more advanced actuator that the Black series does not use.Designed for stand alone or RAID operation.Vibration is undetectable.Noise level is low enough. On par with WD Black drives.Cons:It's not new from "current" stock so AFAIK WD will not honor the 5 year warranty.Not a 256Mb cache.I didn't buy two of them. :(

UPDATE: I decided that I dislike being lied to even if the drives technically worked. None of the drives showed any physical operational issues after testing but having the SMART data erased just drove me nuts. I sent them back to Amazon and received a quick refund. If they retained their SMART data and were sold as used I would have kept them.I noticed the listing conveniently doesn't mention if the drives are new or used which is where they get you. These drives are pulled from servers just as their warranties expire from WD (their website confirms this via the serial) and then they wipe off the SMART data and sell them as though you are getting something new. I know this for a fact because when they attempted to wipe the SMART data they weren't as thorough as they thought and some information remained. I purchased three drives from DBSKY and each one had over 3 years of runtime on them (25K hours or more) yet the "standard" smart display showed them at 0 hours. However with all of this known I am putting the drives through some very deep testing and if they pass I might be willing to let them slide since they are like 25% of their normal cost and they are the best drives made by WD with a MTBF of up to 2.5M hours. It's like buying a car that had the odometer reset though and I am annoyed enough at this scam tactic that even if they do work great I still might send them back out of principal.

Almost any time I need to add a drive to a Windows PC it is a pain. Its never the drive at fault, but simply Windows. I recently added a Windows 11 system to by office. It was tis system That was getting the new drive. The drive is super... and installed easily, once I figured the difference in incantations from Win 10 to 11. I haven't tried this new HDD on a non-windows machine, yet, but I don't expect to have any issues. Linux seems to be far more stable than Windoze.

Great drive and price, but noisy. I put one on my DVR home security in my bedroom. It sounds like you're brewing coffee. This is normal for head seeking drives but something to know.

Like any unformatted drive, you will need to format and get everything setup before using it. Lots of YouTube videos to help out there. The install itself was as easy as plugging in the SATA cord and power. Your case determines how easy that is. Then secure the drive in your case. Literally less than 10 minutes for my case and it only took that long because I made the wires look nice.The drive works very well. It accesses quickly. The only slight complaint is the drive is somewhat noisy you will hear the clicking as it reads and writes. Part of that is the mounting in my case, part of that is the rest of the computer is almost silent. In a normal case and anywhere there are noisy or background drone from fans, you will not hear it in most instances.The storage capacity is excellent and I will buy at least one more for all the videos we produce.

super affordable when I bought it and now is part of my computer build. 100% worth it

Wish I would have read the reviews first. Not sure how a product being sneakily sold used has so many good reviews. This is 100% a used drive. Came in unseald anti static bag, scratches on the sides from where it was installed in another computer. NO WHERE DOES THIS SAY USED DRIVE. (well in the questions section it does) Seller is ripping people off and should be held accountable. Too bad for me this was ordered for a remote location and I was not aware it was used till I got there to install it. Luckily for me it's an 8th drive in a raid for backups so I put it in but NEVER would have purchased if I knew it was used. Buyer beware on this one.Question for western digital store seller, are the enterprise 4tb drives you're selling new with a 5 year factory warranty?Answer:These are not new drives with the full 5 year warranty. We do have some with 3000 hours or less. Best regards, Effective ElectronicsBy Effective Electronics, LLC SELLER on March 3, 2021UPDATED Seller did NOT email me. They called me and tried to claim that the drive would have shown 0 hours. Not saying I'm an expert in IT only 25 years of experience.. but there are several ways to 0 out the SMART data on a drive. Common to see on refurbished drives. MASSIVELY DISSAPPOINTING

It's a bit loud and that's something to consider if you're deploying this into a computer that needs to be low noise. Access and read/write speeds are very good. These black labeled business class drives have internal components that are supposed to outlast most of the blue and red labeled retail WD drives, as they're intended for more constant use in a low end server or NAS. My last WD black enterprise drive was 7 years old before it started failing, and that was used mildly as a data drive daily.
