- Key Specs
- Storage Capacity: 4000 gigabytes (Measured in megabytes (MB), gigabytes (GB) and terabytes (TB), this is the amount available for storing files, music, movies, photos and more. The total includes the capacity of the hard disk drive and solid state drive if both are included on the computer.)
- Storage Drive Type: HDD (Traditional, mechanical hard disk drives are the most common type of storage because they're relatively inexpensive and offer huge capacities. However, they also generate both noise and heat. Solid state drives, also known as SSDs, are many times faster than hard disk drives and have no moving parts to wear out, but typically offer less capacity for the same price.)
- Rotational Speed: 5400 revolutions per minute (The rate at which the hard drive spins its platters. The higher the rotational speed, the faster the drive can read and write data.)
- Maximum Read Speed: 175 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)
- Maximum Write Speed: 175 megabytes per second (The greatest speed at which the device can write information; for example, saving files.)
- Form Factor: 3.5 in.
- Interface(s): SATA (Refers to the types of connections that devices use to interact and communicate with each other.)

A: the 4th picture says the model on this is wd40ezaz. on western digital's site, it shows this: CMR: WD5000AZLX, WD5000AZRZ, WD10EZEX, WD10EZRZ, WD20EZRZ, WD30EZRZ, WD40EZRZ SMR: WD20EZAZ, WD20EZBX, WD30EZAZ, WD40EZAZ, WD60EZAZ unless the picture is wrong, this is an SMR drive.
A: MTBFs vary between manufacturers AND the characteristic usage class of the drive. Manufacturers like to claim this time to far exceed 11 years but reality shows a fairly high variance between manufacturers and the “class” of drive. In this case the WD 4TB “Desktop” drive in avg daily “consumer grade” usage, should last 7 years or more easily, even in 24/7 powered up state as I run such systems. The Western Digital quality is fairly high and you should see a low 2-3% overall annual failure rate across their quantity of shipped units. When you need higher grade performance, look to a “NAS” class drive . . . remember the old saying of you “get what you pay for” is a good rule of thumb. Hope it’s helps.
Q: Is this hard drive capable for my ps4?
A: I think as long as you have the data bank adapter youbshould be able to use it on a ps4

Arrived and works exactly as advertiesd.
Usually Getting around to buying hard drives is quite the unreaosnable gamble as its been inconsitent with the model numbers. Fortunately I got exactly what I was after: a 4TB CMR hard drive that ends with “EZAX”. As for the general review, its a simple plug-n-play setup for devices that can hold 3.5” hard drives. Included in the box are 4 mounting screws, as wall as general product documantion and warranty information.

Great For Nvidia Shadowplay Recording
I wanted a separate drive (with lots of space) for directly recording and storing Nvidia shareplay game clips/highlights. I originally wanted the WD red version but it wasn't in stock. I settled for this and it has been perfect so far for my use case. It has no problem continuously recording a 10 minute loop of 1080p 60FPS gameplay footage at a 50k bitrate. And both of my 1TB SSD's are no longer almost full (which I learned is bad and slows them down) Don't forget to download the WD Dashboard app. It's not required but it's still pretty cool to have.
