WD - NAS 4TB Internal SATA Hard Drive for Desktops
- Key Specs
- 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.)
- Interface(s): SATA (Refers to the types of connections that devices use to interact and communicate with each other.)

- Bare Drive: true (Drive is sold without any pre-installed software.)
- Features
- Security Features: None
- Data Encryption: false
- Usage: Network Attached Storage (NAS)
- Memory
- Cache Buffer Size: 64.0 megabytes (The data capacity of the cache buffer (or disk buffer) that acts as temporary memory for the drive. The cache holds the most recently and frequently used data to save the drive the extra step of pulling it from permanent storage every time it's needed, which helps increase the drive's overall speed.)

Q: What's the difference between this drive and the WD40EFRX?
A: None, that is what this drive is inside the packaging. This is the retail kit. See my attached screenshot from my NAS showing the two I just picked up recently.
A: In simple terms, these can be used in regular PCs, but you are paying for features that you will not use or not very helpful for regular PC user. In fact, one could argue that one of the features supported by these drives is actually (mildly) harmful to ordinary user. Now the long explanation. RED drives are meant to be used with RAID controllers. RAID controllers manage error recovery differently and therefore need disks to limit the time they spend recovering data from platters. Thus there drives will not try as hard as they could try to recover data when something goes wrong. This feature is called TLER (time limited error recovery) NAS drives have TLER supported and usually turned on by default. It may be possible to turn it off. However why would you pay for this and other features (like vibration tolerance/sensors etc) and not use them? Note that desktop drives usually do not have TLER and you should not put them in a RAID enclosure.
A: Sure, as long as the dvr accepts sata drives and not an older one that only takes ide drives.
Q: Is this SMR or CMR Drive? P.S. BestBuy should include this in every HDD product discription.
A: A little bit of researching shows it's SMR (shingled magnetic recording), as are all WD RED. WD Red Plus & WD Red Pro are CMR (conventional magnetic recording) source - https://blog.westerndigital.com/wd-red-nas-drives/
Q: Do the WD NAS drives include the SATA cable.
A: No. You only receive the harddrive.
A: This item is for desktop computers.
Q: is this 2.0 or 3.0 NASware firmware
A: It prints NASware 3.0 on the drive.
Q: Will this drive work in Apple Macintosh G3 running Mac OS X 10.4.11?
A: WD Red drives are optimized for NAS usage. You should probably go with a blue series or black if you want higher performance. Those are optimized for desktop use.
