    • 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.)

Q: What is the cache buffer size of this hard drive?

A: This hard drive has a cache buffer size of 64 megabytes.

Q: What is the storage capacity of this Western Digital hard drive?

A: This Western Digital hard drive has a storage capacity of 4TB.

Q: Does this hard drive come with any software?

A: Yes, this hard drive comes with Acronis True Image WD Edition cloning software.

Q: What is the maximum read speed of this hard drive?

A: The maximum read speed of this hard drive is 175 megabytes per second.

Q: How is this hard drive protected from damage during transit?

A: This hard drive uses NoTouch Ramp Load technology where the recording head never touches the disk surface, which provides better drive protection in transit.

Q: is this drive PMR OR SMR?

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.

Q: What is the life expectancy of this hard drive? Ie: Known or predicted time between failure in hours, in normal daily use.

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.

    get on sale

    this is my 2nd blue WD purchased ,, since bestbuy put them on sale again ,, i wonder if these hdd are will be phased out in favor of ssd is the reason .. so getting some extra on sale seems logical to me .. also,, i been using the free acronis backup software making backups .. finally without having to buy it .. i used acronis to create a backups on the 1st blue ..and then created a bootable clone on the 2nd blue .. i also worked on creating a bootable clone on a usb WD passport drive too but not tested a boot with it yet .. however when the blue booted ,,, it took about 4 to 5 minutes where the motherboard ssd boots takes just a minute .. another thing which i liked was the boot ssd was 2TB and had 2 partitions of 1TB ,, and when the blue 4TB bootable was created ,, the acronis created 2 partitions of 2TB each .. .which make me even more happier .. my eventual plan is to use the bootable blue to now make a bootable 4TB ssd ,, and keep the 2TB ssd and boot blue as backup out of the desktop ..
