5 out of 5 eggs

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive -Bulk

Pros: Ran full surface scans with the WD software and badblocks in Linux. Four drives passed clean and are now running in a raid 10 on an Adaptec 6805E.

The packaging imo was great on these drives and the main large box showed no signs of mistreatment.

Gonna rate these a 5 egg. Will review again if anything changes.

Cons: 4TB takes roughly 9hrs for a surface scan. Times that by four and uhg. Wish there was a faster way to make sure drives are good from the get go.

1 out of 5 eggsReplacement Drive DOA

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive -Bulk

Pros: None

Cons: I have ordered 3 WD RED 4 TB drives from Newegg - 2 in an initial order and 1 to replace the DOA one in the 1st order. The replacement drive is also DOA. The 1st shipping charges back to Newegg cost me $10.40. Now I have to ship the 2nd DOA drive back to Newegg, wasting another $10.40. These shipping charges have now cost me almost all my coupon savings I got from Newegg while ordering these drives while the drives were on sale.

Do I dare order a replacement drive from Newegg AGAIN and waste more shipping charges on another WD RED 4 TB DOA drive?

Manufacturer Response:

4 out of 5 eggsWorking so far

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive -Bulk

Pros: Not expensive. Low heat. Still working after 3 months.

Cons: 1 of the 4 that I initially ordered was DOA.

Other Thoughts: My setup is running these as Raid5. It is very important to keep these guys well ventilated as heat is a killer and is much more likely when sandwiched next to each other in a raid situation.

5 out of 5 eggs  No Hassles.

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive -Bulk

Pros: Installed, partitioned, and then balanced the drive pool. This makes 19tb and no dive issues to speak of. WD stands behind their product, if you have an issue, deal directly with them to avoid the shipping costs. This my only 4tb red, the other 5 are 3tb green and reds, love these drives.

Cons: None

Other Thoughts: Very quiet and run cool. I can keep them enclosed in my desk and not have to worry about overheating issues.

5 out of 5 eggsRecent Shipment - All A-OK

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive -Bulk

Pros: My most recent purchase of 5 drives has passed extensive testing. I am rerunning those tests to be doubly certain the drives are "sound" before placing them into service in my home NAS.

Cons: None so far that would deduct an egg.

I noticed that 2 of the 5 drives had circuit boards that "looked different" compared to the other, but all 5 drives had the same "date of manufacture".

At least 2 drives had anti-static bags that were slightly torn, not bad enough to remove the drive, but a tear that opened the bag and defeats the purpose of the dessicant. That could have come from handling the drive during packing for shipment.

Other Thoughts: Always run drive tests before placing purchased drives into service. The drive manufacturers make decent tools for testing. Use those tools, then save and date the test results.

Also, note the drive serial number, date of manufacture and any other issues when unpacking the drives.

The new packaging system from Newegg seems to be working for me. The most recent batch was packed like the Newegg video showed. In my case the individual drive boxes were sitting against the bottom of the box. In the past any drive that was not well cushioned or sitting on the bottom of the box usually encountered errors. The new packing lessens that risk, but I still test all drives.

Overall my success with drives purchased from newegg is improving and that is probably due to the new packing method.

1 out of 5 eggsDOA

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive -Bulk

Pros: Ordered 2 WD RED 4 TB - one worked 3/4 of the way other DOA

Cons: QNAP NAS Expansion from 2TB RAID 1 to 4TB RAID 1. First WD RED worked fine during migration, once second 4TB WD RED started mirroring, the first started to show bad read/write blocks and the second drive did not pass at all. I am returning these 4TB WD RED and picked up 2 HGST Deskstar NAS H3IKNAS40003272SN(0S03664) 4TB based on reviews. Lost the advantage of my coupon savings and almost 16hrs of frustration dealing with these paperweights.

Other Thoughts: Why do I have to pay for returns if the product does not work?

Manufacturer Response:

5 out of 5 eggsSo far... AWESOME

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive -Bulk

Pros: I have had two WD Red 3TB Drives in service for over a year now. Recently I ordered a 4 drive NAS and I ordered 5 WD Red 4TB drives for it. I ordered 5 in case one was DOA and more importantly to have a spare on hand in case of a failure in the RAID 5 set. On arrival I used WD's tool to do the extended test on each drive one at a time. A time consuming task but IMO essential when you're talking about putting this much data on a drive. All five passed. So I put them in the NAS which built it's raid and immediately ran a consistency check of it's own on the volume, also passed.

Cons: They aren't bigger and faster.... really I don't have any cons....

Other Thoughts: Overall I am impressed so far with these drives and with WD Red drives in general. Let's be honest we're pushing the edge of current technology in storage capacity with these drives. I always test my drives and I have learned the hard way to expect failures. So far the Reds have not although I realize others may not have had as good luck. Overall though I would put them at the top of the current heap.

1 out of 5 eggsNever Again

This review is from: WD Red WD40EFRX 4TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" NAS Internal Hard Drive -Bulk

Pros: None that give it an edge over any other provider!

Cons: I ordered 5 of these drives. Out of the original order 3 were DOA. I paid over $30 to return the 3 to Newegg for replacement and out of the 3 replaced 1 was DOA!!!!! Another $10+ to ship it back.

Too bad I had to give it 1 star!!! I wanted to give it 0.

Other Thoughts: If you look at my original posting you will see WD gave me lip service about how they do burn-in testing, etc. Pure trash in my estimation. I will have paid an extra $40+ dollars to the original $900+ for these drives.

Save your money, time and aggravation - just not worth it.
