3 out of 5 eggsExcellent when not DOA

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

Pros: Excellent drives as far as I've seen. Have four other Greens running in a RAID 10 and have not had any trouble out of them. They seem to be fast enough/competent enough for a backup solution which is how I'm using them.

Cons: Out of the six WD Greens I have purchased, two have been DOA and had to be replaced. One out four 2TB models and one out of two of these 4TB models. I don't think they like shipping very much.

Other Thoughts: I hate having to spend extra money on RMA shipping to send a product back to Newegg that was bad before I even received it. I think Newegg should cover the cost.

5 out of 5 eggsAnother WD win for me

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

Pros: It's a WD that works just like it's supposed too. Using in my HTPC setup currently.

Cons: It's a little slower than the Black WD drives I have, but I expected that.

Other Thoughts: Been using WD exclusively since way back when Maxtor dropped their 3 year warranty. Never had a problem with WD, only one RMA ever, and they were great with it.

3 out of 5 eggs2 Out of 3.

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, very low cost.

Cons: I was building a new 6 drive RAID server. I bought three of these drives - and three of another brand. Of the three of these, one was DOA. None of the other brand were DOA.

1 out of 5 eggsOnly halfway there, WD

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

Pros: Wasn't DOA.
At least half the advertised size.

Cons: SMART info and sticker label indicated 4TB, I expected to see 3.6TB in gparted, what I saw was 1.64TB even after setting the partition table to GPT.

Model: WDC WD40 EZRX-00SPEB0
Size: 1.64 TiB
Path: /dev/sdc

Partition table: gpt
Heads: 255
Sectors/track: 63
Cylinders: 219051
Total sectors: 3519069872
Sector size: 512

Other Thoughts: I've had no trouble with Seagate's ST4000DM000 - it even indicated 3.6TB before it was set to gpt to enable 4TB partitions.

I've owned several WD Greens' before: 500GB, 1TB and 2TB variations - each with several years of literal-flawless operation. This purchase outcome has obviously been dissapointing for me and I will require an RMA for this purchase.

Manufacturer Response:

Dear Kris,
It is important to verify that in the BIOS the drive is seen in its full capacity, and if not, you may require a BIOS or controller update to your Motherboard. If the device is recognized for the full capacity in BIOS, and the issue resides within Windows, we recommend verifying you have the latest Windows updates and drivers for your OS and hardware components. If you feel at any time that our support team can be of further assistance in providing you with a positive resolution to your technical concerns, please do not hesitate to contact us directly at (800) 275-4932, or via our support website at: http://support.wdc.com/rs
Please indicate within the online case creation or with the first support agent you speak with, that you are responding to a Newegg review, so we route you and your information to the correct team members.

5 out of 5 eggsOrdered 2, Now ordering 2 more

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

Pros: The price for $164.99 isn't bad for 4tb of space, i'm replacing old 1tb-2tb drives that have past their warranty and are beginning to fail. I chose this brand because they are great for storage in my HTPC, since I don't don't require every drive for massive power use and just storage these so far have worked the best.

They are formatted in ext4, under ubuntu-server, I ran several manufacture diagnostics before using them in production.

I do have a 4tb WD Black for power use, video editing, if I want to convert a file.

Formats out to 3.73tb in ext4.

Cons: None really, aside from shipping, I plan to buy more of these but I'll get them from retail outlets.

Other Thoughts: It's 4tb of space! It will take me a long time to fill up 4 of these.

1 out of 5 eggsFailed to Write After A Couple of Months

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

Pros: Got two of them last Thanks Giving, so the price is good.

Cons: One of them developed bad sectors and cannot write.
S.M.A.R.T. shows "Pending Sectors ......."
I am now dumping my 4T contents to a couple of small disks, so painful.

4 out of 5 eggsGreat Drive, Beware Newegg Packaging

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

Pros: These drives work great for deasktops and offline data archival. My newegg fail rate is 1/4 my seagate fail rate over the past few years.

Despite newegg's "new" packaging, they still use to substardard packing methods.

Order 20? Perfect! You'll get a carton like the manufacturer ships in. in the hudreds/thousands of drives i've ordered, drives packaged by the manufacturer in the 20 packs rarely have any issues. This is the best way to buy hard drives.

Order 1? OK, You get Newggs new packing, individually packaged in a box. Haven't had an issue with this method *yet*. Since I have seen popped envelopes, I'd bet it's just a matter of time.

Cons: Order 2-19? If my experience is like yours, you'll get drives in a box, all in the new "inflateable envelopes", loose. I recently had an order of 5 this very way, with 2 of the drives infleated envelopes burst. I immediately knew I had a problem. neither one spun up. RMA to newegg went off without a hitch, until they clamed that *I* had caused the phsical damage to one of the two DOA's.

I am the CTO of a tech company that regularly orders, tests, uses, deploys, retires and examines disks. Never once in my tests has a drive been phsically damaged in testing. Never once have I had a company blame me for physical damage caused by their negligent handling SO MANY TIMES. This is least the third time newegg has, and tried to deny my RMA post-receipt. This is bull, and I called them on it. They relented only after extensive conversations about a long history with their company, purchasing hundreds of thousands (perhaps millions) of dollars worth of gear from them.

Other Thoughts: Newegg needs to "bag" and "box" *each* drive, then put all those single boxes in another box, pacjed tight enough (with packing material) that the drives dont knock around eachother.

Until they get this right, ordering drives from Newegg is a crapshoot. And they will blame you for the damanger caused.
