5 out of 5 eggsExcellent NAS Drives

This review is from: WD Red 4TB NAS Desktop Hard Disk Drive - Intellipower SATA 6Gb/s 64MB Cache 3.5 Inch - WD40EFRX

Pros: Update 2/3/16:

After 1yr and 3 months of 24/7 use, 1 of the 6 drives I purchased began failing SMART Long Tests, which eventually turned into unreadable sectors on the drive. I did an Advanced RMA through Western Digital. They used UPS 2 Day Air to send me a brand new drive! I was dreading the return process, but WD makes it extremely easy to return faulty drives. Luckily these drives have a 3 year warranty, should anything go wrong. I was able to use the same box/packaging to return my faulty drive, which worked out well. Although the drive failed, I am extremely happy with WD's RMA process. So for that I will keep the 5 star rating. Also, the new drive was manufactured in Jan of 2016 and came with NASware 3.0! Couldn't be happier with the return process. Thanks WD!

Purchased 6 of these during the Black Friday sale at a price that couldn't be passed up.

Ran SMART Conveyance, Short, and Long tests to ensure no drives reported any errors. All came back fine, which shocked me, due to the amount of DOA / Bad Sector reviews. Perhaps I just received a lucky batch.

Running all 6 in a RAIDZ2 (RAID6) FreeNAS system. Performance has been great so far. System is capped by Gb LAN speed (~100 MB/s read/write).

Cons: SMART results show the Load Cycle Count (Head Parking) increasing too quickly for my liking. WDIDLE3 utility can be used to disable Head Parking, potentially increasing drive life in a 24/7 server.

Other Thoughts: All 6 of my drives were manufactured in July of 2014 and unfortunately came with NASware 2.0, not 3.0. However, Newegg does list the drives as NASware 2.0, so I can't fault them for that. If you want/need NASware 3.0, buy them directly from WD.

Overall, no complaints. No dead/bad drives and they're performing as expected.

This review is from: WD Red 4TB NAS Desktop Hard Disk Drive - Intellipower SATA 6Gb/s 64MB Cache 3.5 Inch - WD40EFRX

Pros: None

Cons: First hard drive I've ever had trouble with. Either I was lucky in the past or this drive is seriously problem prone. Wasted a lot of my time before I figured out the problem was with the drive and not my new system. Oh well.

Other Thoughts: Duplicate post, I inadvertently gave 5 eggs first review. Sorry.

5 out of 5 eggsPretty sweet. Maybe I got lucky though

This review is from: WD Red 4TB NAS Desktop Hard Disk Drive - Intellipower SATA 6Gb/s 64MB Cache 3.5 Inch - WD40EFRX

Pros: - I ordered 8 of these and they all worked! Better than I can say for some other reviews I read.
- I'm getting between 30 and 70 MBps, but that's 8 drives in RAID 6.

Cons: None

Other Thoughts: Before I ordered these, I had heard that these things had a high chance of arriving DOA but could be RMA'd if needed. Sure it's a pain if that happens, but they seemed to be designed for my exact use case. I took the chance and ordered. Either WD seems to be doing better quality control or I lucked out. Gotta share the positive stories too I guess.

5 out of 5 eggsI *only* use Western Digital Drives

This review is from: WD Red 4TB NAS Desktop Hard Disk Drive - Intellipower SATA 6Gb/s 64MB Cache 3.5 Inch - WD40EFRX

Pros: I used two of these drives in a RAID 1 configuration in my Synology DS212j and they performed flawlessly. For two years they were used constantly, until I upgraded to the 6TB versions.

Cons: Expensive, but worth it.

Other Thoughts: I'll never use another brand of hard drive. With a decade of IT experience WD has never ceased to amaze me. WD is the Mercedes-Benz of hard drives.

3 out of 5 eggsone out of four DOA

This review is from: WD Red 4TB NAS Desktop Hard Disk Drive - Intellipower SATA 6Gb/s 64MB Cache 3.5 Inch - WD40EFRX

Pros: 3 out of the 4 drives I ordered worked. They appear to work fine, but haven'd done any heavy lifting with them yet since I'm still waiting on my RMA replacement for the 4th drive before I really start filling up the NAS with data.

Cons: 1 out of 4 drives ordered was DOA. Apparently this is a serious issue with these drives, but the bundle deal with my QNAP NAS was too good to pass up. I guess maybe I'm better off than a lot of folks, based on skimmign the reviews. We'll see if the replacement drive works when it gets here.

1 out of 5 eggsReally hate to have to write this review...

This review is from: WD Red 4TB NAS Desktop Hard Disk Drive - Intellipower SATA 6Gb/s 64MB Cache 3.5 Inch - WD40EFRX

Pros: The same drive purchased from a different on-line retailer works great in my QNAP NAS. So, I think the drive is a good drive.

Cons: 2 out of 2 (4) TB WD Red drives I purchased from Newegg arrived DOA. Not much else to say con-wise as the drives would not even initialize.

Other Thoughts: I have been a long time newegg.com customer. I still appreciate newegg for great customer service and excellent pricing. However, I have to agree with many of the other reviewers of this drive. There is something seriously wrong with newegg and these WD Red 4tb drives. I purchased (2) drives from newegg as part of a BF combo deal. Since I wanted to run a raid 5 stripe, I needed a 3rd drive for my QNAP NAS (didn't want to purchase 4 drives at once). I ordered a single drive from another on-line retailer who matched newegg's price per drive. When I plugged all (3) drives in my NAS, the drive from the other on-line retailer spun up instantly with no issues. BOTH drives ordered from newegg started clicking (reminded me of the old days of Seagate 1.5TB drives that would start clicking and failing almost immediately) and then failed to initialize. I moved the drive from the other reseller to all (4) slots in my NAS to ensure the NAS did not have an issue and the drive initialized flawlessly in all slots. I can only conclude like many others have posted that either newegg has issues in logistics (inventory/packing) or they have a supply chain issue. I ended up returning the drives to newegg for a full refund (so the 1 egg goes to newegg's great customer service). Had to order replacement drives from a different etailer for more money since I would have no confidence in replacement drives from newegg arriving in working condition. So, I'm a bit steamed at newegg as I could've bought all 3 drives from the other etailer for less money on black Friday (the deal is gone now). But, since newegg had set the price point, I figured they earned my business. I should've listened to the other reviews and bought all 3 drives from the other seller originally. I still value newegg as a good partner, but would not trust any drive they ship me until the reviews trend upward. Just my 2 cents based on the reviews I read an my experience.

Manufacturer Response:
