5 out of 5 eggsSo far so good.

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

Pros: They have been on 24/7 without issue for 1 month now. Lots of storage.

Cons: None

Other Thoughts: I have these in RAID 1 for my FREENAS server, they are dedicated to PLEX. They have been on 24/7 for over a month now and seem to work as advertised.

I have the older 2TB reds in RAID 1 as well that have been going strong for almost 2 years 24/7. RED drives rock!

4 out of 5 eggsGreat Drive, Wish Warranty was better

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

Pros: -As most WD products I've onwed, I can honestly say this is the only brand driver that I trust.

Cons: -Either I'm spoiled by the WD Black 5 year warranty, or I feel it showed a bit of greed when WD offered the Red Pro with 5 year warranty.
I mean, after all, if WD Red is the NAS flagship equivalent of a WD Black in a desktop environment, then the same warranty should have conferred. Making us pay extra for 'WD Red Pro' when the only difference between Red and Red Pro is the warranty length, is a deplorable money grab, yet all too expected in today's corporations. Would it really kill you rise above the corporate status quo Western Digital?

After all, your products are great... what's there to lose that could possibly be worth more than the tremendous boost in Brand Perception and serious respect from your customers?

3 out of 5 eggs1 DOA, 4 just OK

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

Pros: Low heat. Low noise. 2 year warranty gives peace of mind against all the reports of failures in these reviews. Reasonable speeds for the price.

Cons: Just my luck, like so many others before me, I got a dud !!!

Well, 4 out of 5 working seems to be acceptable for today's quality assurance people when they release stuff from production, so I guess I should just shut the hell up and suck it up.

RMA underway.

5 out of 5 eggsCheap NAS Drives

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

Pros: 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.

5 out of 5 eggsSo far so good

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

Pros: The two units I purchased worked and continue to work fine for the past 4 months. I have them installed in a ReadyNAS 516 along with two additional 4TB Red drives I purchased elsewhere. I am pleased with the performance and so far no reliability problems. NAS runs 10 hours/day, shuts down overnight.

Cons: none so far

5 out of 5 eggsWorks as advertised

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

Pros: stable, good speed and no errors yet

Cons: none

Other Thoughts: Once formatted with a GPT partition and added to my media server, I was able to dump 2TB to it and it's been running without issue since

3 out of 5 eggsThey all work

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

Pros: Reasonably priced low-power drives with good performance.

Cons: Shipping accuracy

Other Thoughts: Given the comments here, I ordered drives from two vendors in hopes of sampling different lots for a 7-drive NAS build. All of the drives were run through burn-in and WD Lifeguard tests. Six of the seven passed with no errors of any kind. The seventh (Newegg) drive turned out to be 2TB instead of the ordered 4TB and was not tested. I am still hoping to resolve the issue with this drive despite two unanswered attempts so far. Perhaps Christmas is clogging the pipes.

5 out of 5 eggsAwesome drives.

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

Pros: I bought 5 of these last christmas to add to a synology nas. They have all worked flawlessly so far. Still no reallocated sectors on any of the drives. I just ordered 5 more of the 4tb reds to add to a Unraid nas that i'm building. I'm pretty much sold on WD red drives and will be buying even more in the future. Just wish the 6tb reds would come down in price.

Cons: None

1 out of 5 eggsDO NOT BUY FROM NEWEGG

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

Pros: There is nothing wrong with the drive. It works extremely well.

Cons: The problem is with newegg. They are distributing an old version of this drive with and old firmware that is not upgradable. When calling and emailing support, no one at newegg even knew what a firmware was. The told me to call WD if you can believe that. WD has had their NASware 3.0 out for quite a while. This drive has the old 2.0.

Other Thoughts: This is a problem with installing on RAID arrays that have the newer NASware 3.0.
