2 out of 5 eggsBought 4 - 1 failed on first day

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

Pros: Big

Cons: Failure rate is not acceptable. Loaded in a RAID 10 and one of four disks immediate showed a failure

Other Thoughts: Not sure if this Red line is all that it is cracked up to be.

5 out of 5 eggsGreat drives and great Newegg support

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

Pros: These are great drives for NAS/RAID (not super high performance, but generally reliable). I ordered several, and had one DOA, which Newegg replaced promptly.

Cons: Expensive when not on sale.

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

Pros: 4TB of space when they work.

Cons: Of the 6 that I originally bought 3 of them are RMA. One had the click of death and the other two were reallocate errors galore. Your mileage may vary.

Other Thoughts: Do yourself a favor and pick another drive for a peace of mind.

1 out of 5 eggsWD Red 4TB - 2 ordered - 1 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: DOA

Other Thoughts: I'd been through the reviews and saw some stating Newegg was shipping product with old firmware and some DOA right out of the box. I really didn't think I'd be writing the same review, but here I am. Two 4TB Red ordered. One is DOA! Totally disappointed in myself for thinking it wouldn't happen to me, NewEgg for continuing to ship these defective units, and last but not least ... WD!

1 out of 5 eggsfailed in 2 months

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

Pros: Purchased 2 for a Synology 214+ NAS. One drive failed in less than 2 months. Was my first WD purchase and surely my last. Never had any issues whatsoever with Seagate or Hitachi in the past.

Cons: Failure rate high

5 out of 5 eggsRunning strong

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 3 of these running in my Synology NAS for about a year now and have had exactly 0 problems.

Cons: None

Other Thoughts: Obviously, these are going to be louder, slower, and hotter than an SSD, but when it comes to something like a NAS, reliability is the name of the game and these have done very well so far. (That's not to say that these are particularly loud, slow or hot; they aren't.)

5 out of 5 eggsGreat Drives for Synology DS 1815+

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

Pros: My primary objectives for ordering the 4TB NAS drives from Newegg were: shipping/handling reviews(what good is a drive if it's not shipped properly), price, and premier membership.
I ordered 3 of these drives and received them the next day (on a 2-3 day delivery promise). The packaging was 'excellent' with encased bubble tube cases and placed individually in custom fitted boxes which were then placed in another larger box (also fitted for the individual boxes. No issues here!
At the same time, I had ordered a Seagate 4TB NAS drive from another store on the East Coast after receiving assurances that their drive would be shipped with adequate packaging. Their drive came in a slightly oversized box with unsecured bubble wrap around the drive (it had come out of the wrap and was loose in the box). Luckily, the drive tested out ok with no internal/external damage.
I decided not to order anything from another site where I have prime membership after seeing photos from customers of drives shipped in large boxes too large with the drives only in static bags bouncing around hitting each other. Also, many of their customers complained of DOA drives (probably due to bad packaging).
The reason I'm obsessing about packaging is because I worked in the drive industry for 15 years and drive packaging and handling were key to quality and reliability.
Newegg knows how to ship these sensitive pieces of equipment. Well Done!
The WD drives themselves are quality units. I noticed in my Synology DS 1815+ that they run at a cool 80 degrees, but the Seagate 4TB NAS runs a little cooler at about 74 degrees. Both drive models have been running 24/7 for the past two weeks with no issues. I'm looking at populating my other 4 slots with WD 5TB drives once I start running low on space.

Cons: None

Other Thoughts: If you are ordering NAS drives and want assurance and peace of mind (in case you need to do a return) buy the membership (includes free shipping and returns). Don't skimp on this piece of insurance.
