1 out of 5 eggsBad drive

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: Cheap for 4TB of space.

Cons: Does not work can not put files on the drive without it dismounting itself in windows. Very poor product glad I didn't lose any files because of this drive, but that is only because I couldn't copy anything to it. Junk drive really unstable

Other Thoughts: I probably should have gone with a WD black over their green drive or gone with the two 2TB drives I was looking at instead of this. Drive is new though and not a refurb as I checked how many hours of power on time it has (13) so even when it dismounts itself it is still 'on'.

1 out of 5 eggsVery Unstable Drive

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: Cheap for a 4TB drive.

Cons: I'm not sure what the deal with this drive is but every time I start to copy files to it the drive dismounts itself from the computer and requires rebooting to bring it back up I'm pretty let down by this drive so far.

Other Thoughts: I probably should have gone with a WD black and not a green all in all it would be faster to back up my files.

5 out of 5 eggsGreat Overall

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: Drives are the cheapest 4tb drives around and work well.

Cons: They have the "green" feature that causes the heads to park after 8 seconds. Not an issue for desktops but it causes all sorts of problems on NAS setups. Not a huge issue however it is something buyers need to know

4 out of 5 eggsOk

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: Great storage for the price.

Cons: Nothing directly with WD.

Other Thoughts: Windows has a hard time recognizing the full 4TB and lists it as 2 separate drives. I'm not sure if that's Windows or WD to W7 interface.

4 out of 5 eggs2 out of 3 ain't bad.

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: They're 4TB of HD space at a fairly reasonable price. I got 2 of them on sale and then decided to get a 3rd to build a RAID 5 instead of a RAID 1 that I originally planned for. for the most part I'm happy with the purchase.

Cons: 1 of the 3 was DOA, but the worst part is Newegg charing me almost $13.00 for a replacement, which I determined I'd need the day I opened it. Why is it my responsibility to pay for the manufacturer's or Newegg's garbage? I've been a customer with Newegg for years and very loyal, but this is bullcrap. I'm highly considering doing a lot less shopping here if everytime I get faulty hardware I have to pay for it, and if the replacement is bad, I'll have to pay for that too. That's unacceptable. If it's not the customer's fault and it's well within the return period, then these charges shouldn't be on the customer.

5 out of 5 eggsGreat storage hard drive

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: Price per TB is reasonable.

This 5400rpm is as fast as my 7200rpm seagate drive.

Runs a couple degrees lower then my 7200rpm hard drive.

Cons: Occasionally VLC stutters might just be VLC going to test this more.

Other Thoughts: Great hard drive but wouldn't use it for my boot drive or games I play often.

I see people taking off eggs for DOA when they haven't even tested it

4 out of 5 eggsGood Drive once replaced

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: Quiet, good value, good performance.

Cons: First one received was DOA.

Other Thoughts: The first unit received arrived within 2 days of purchase and was DOA (horrible clicking noise on boot up). RMA process requires you pay for shipment and they e-mail you a link to UPS label about 15 minutes after you pay for it. They got the unit back about 4 days later and processed both the credit (shipping + previous purchase) and placed the order for the replacement the same day. I got the replacement within 2 days and worked great. Whisper quiet and quick enough for a large storage device.

1 out of 5 eggsBest Drive out there

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: none buying from newegg.

Buy it elsewhere and it will last for ever. I have plenty of WD drives that are working fine ten years later.

Cons: Buying from newegg.
I've never had a problem with a drive purchased from other retailers. I've never gotten a drive from newegg that didn't need to be returned at least once.

Other Thoughts: Pay the extra and buy it from a local shop.

5 out of 5 eggsDesign to fail but you can fix that

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: Quiet, affordable, can be reliable if you disable the self destruct feature, essentially the same drive as the red except missing one not so important feature

Cons: this drive will eat itself alive in certain situations if you do not run a program that changes how often it parks it's heads.

Other Thoughts: this drive has a feature that parks the heads after 7-8 seconds of inactivity. It can only handle 200k-600k parks and is rated at 300k. You can easily rack up thousands of parks a day. There are people who hit 600k in a few months. There are people who rack up 10k in 3 years. Depends on how it's used.

Parking the heads saves .7w so if you have 10 drives that's like a 70w bulb.

The Reds parks there heads as well... After several minutes. Saving the .7w when not in use.

Lastly if using these in a server make sure it's a software raid server like freeNas w/ zfs. If you use any expensive raid controllers flash them to be in IT pass-through mode. Reason is some of those controllers will drop the drive if the drive finds a bad sector and try's to repair itself.

Most people they don't know if they are using hardware or software raid are using software.

WDIDLE3.exe is the program you get from WD to change when the drive parks it's heads. Just set it to never or 5 minutes or so.

5 out of 5 eggsExcellent 2ndary storage

This review is from: WD Green WD40EZRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive - Bulk Bare Drive

Pros: Large capacity, quiet and just works. No perceived difference in performance over the 2 tb 7200 rpm it replaced.

Cons: None to speak of in my application.

Other Thoughts: My system has a Samsung 850 pro SSD (500gb) for primary storage and uses this drive for 2ndary storage (large data) and backup.
