WD Red Plus 6TB NAS Hard Disk Drive - 5640 RPM Class SATA 6Gb/s, CMR, 128MB Cache, 3.5 Inch - WD60EFZX - OEM

Pros: As I said in my previous review of this drive, it's extremely quiet and vibration-free. Quietest drive I've ever seen.

Cons: None.

Overall Review: I wrote in my previous review that I would buy a second one of these drives, and I did. I now have two of these in a Synology DS212j NAS, and it's dead quiet. So quiet, in fact, that I have to look at the LED indicators to see if the drives are spinning. Love them.

Pros: - IntelliPower - 64MB cache - 3 year Warranty - Great price for Server-grade drive

Cons: None so far.

Overall Review: I bought three of these WD Red 1TB drives for a RAID5 configuration after months of research and waiting for the best prices. I have primarily used Desktop Seagate drives in my Home Server that acts as an HTTP/FTP/NAS/Squid/Dansguardian running CentOS and mdadm for over three years; some even with s.m.a.r.t. errors and bad sectors. The performance was terrible ( obviously, I do ask a lot from my servers ) and I decided it was time to upgrade. I pulled these puppies from their fairly well packaged boxes, let them adjust to ambient room temperature, and took pictures of the serial numbers. I immediately registered them with WD warranty website. After they had adjusted, I ran WD's bootdisk and did full scan's on each drive. It took about 8hrs for three drives. No problems at all. I already had a consumer drive running CentOS in my four port SATA so I installed the three RED's and built my RAID5 with mdadm and XFS filesystem. I chose XFS because it has customisations that are great for software RAID's, and performance was rated highly running on Linux. After that was complete, I set up samba and started backing up my data. At first my speeds were not so great, around 20MB/s. So I did some homework and found these options in my smb.conf that DOUBLED my speed: socket options = SO_RCVBUF=131072 SO_SNDBUF=131072 TCP_NODELAY WOW! Now we're cookin'! I get anywhere from 40-46MB/s write speed, and the same read speed over 1Gbps lan. Also, I compared my two servers side-by-side (same makes and models running same CentOS 6.3 and samba) and as I watched the drive led's during transfers from the old server to the new one, I noticed how much more the old drives had to work ( reads/writes ) compared to these RED's. My speculation the reason they didn't have to work as hard is the RED's have 64MB cache, spin at slower speeds with IntelliPower (about 5900rpm), and have less agressive head parking. It was pretty neat to watch my old drives work like dogs, and these new RED's didn't even break a sweat! I'm happy with their performance, the three year warranty, but I will have to update after three years on their durability. As of right now, I am a very happy customer! ~ J.S.

Pros: Low power, runs cool, relatively fast.

Cons: After 76 hours of use, one drive failed a SMART long self-test with a read error. WD advance return wants to pre-charge $260 for one of these drives, returned when the failed drive is received.

Overall Review: Both drives were made in Malaysia. Both were wiped with zeros and had no problems, then were put in a mirror.

Overall Review: I bought this drive due to the price and the warranty which I thought was a good buy. After a month linux kernel was reporting read errors to the drive. I pulled the drive and placed it in a separate workstation, using onboard sata, I wanted to verify the controller or cables on the server was not generating the errors. After receiving the same errors I ran a smart test, smart long test threw errors and was not able to finish due to read errors. I thought okay fine western digital should send me a replacement drive, this has been a nightmare, first western digital would not approve an advance rma, second I have shipped my drive to them and they are just sitting on it, not sending any replacement drives. This is a huge issue for anyone using these disks in a NAS, depending on your use case if another drive fails data lost is a real possibility. As it stands western digital is just holding my drive and refuses to issue a replacement.

Pros: Supports TLER Good for Raid Newer HDD design Price

Cons: I bought two of these for a Raid0 setup. One was flawless out of the box...up and running. The second? Not so much. The SATA power port was mangled. Oddly, the packaging was flawless...not a single dent. This can only mean one thing: someone wasn't checking the HDD's as they were being placed in their OEM boxes nor as they were being placed in the Newegg shipping box.

Overall Review: CS was very good help considering. Sent me a return shipping label (UPS ground...I was hoping for overnight or advanced replacement) and Overnight shipping for the new one once the old makes it past the review process. However, this still sucks because I received the HDD's as 2 for a purpose...RAID0. You can't RAID unless you have both. It will be over a week now for me waiting to complete this build because someone at WD AND Newegg didn't check the product before sending it out.

Pros: This should be a perfectly good drive. I have two predecessor drives, WD40EFRX, still going strong with more than 10,000 hours each.

Cons: I bought it in October, 2021, and installed it in my Debian Linux system, and set it up as a RAID (mdadm) drive. Yesterday, 69 days into the life of the drive, over the course of several hours it registered a number of uncorrectable data errors. I removed the drive from the RAID array. I then made sure the drive was in warranty. It was. I then tried to file for an RMA. This failed with a cryptic error message. I got on a chat with a WD agent. He suggested I try another browser. Same failure. He suggested that the address I had provided for my credit card was incorrect. It was not. He finally agreed to escalate the issue. He wanted me to provide a photo of the hard drive with serial number. Since I had already gotten (and provided) the serial number and other data with SmartMonTools, I thought that was a bit much. WD does not supply test software for Linux. SmartMonTools reads the SMART data from the drive just fine, but there is no guarantee that it is interpreting the data correctly. Seagate does provide software for Linux, but (not having a Seagate drive) I haven't tested it.

Overall Review: Not impressed with either the longevity of the product or the customer support.

Pros: CMR is good, capacity for price is great, low noise level is good.

Cons: 33% DOA rate is disheartening

Overall Review: Expanding my Qnap NAS's capacity into a RAID5 and I purchased (3) 4TB Red's to go with a 4th that I had previously purchased. When I powered it on, 1 of the new drives showed 0TB, so I tried relocating it to another bay and same thing. Returned it to Newegg for a refund and I bought another one, which worked fine.

Pros: Using 4 of these Hard Drives in a Synology NAS. Run great and extremely quiet. Fast read/write. Great for the price

Cons: None at the moment....they weren't free :)
