4TB WD Red Plus NAS Internal Hard Drive HDD - 5400 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" -WD40EFPX

The WD 1TB WDBMMA0010HNC-NRSN drive kit fully met my expectations. I bought this drive to make a RAID1 pair. The drive performed well in my home-built FreeNAS server and provided better network storage performance than expected without any glitches or issues. When compared with 750GB WD Black drives in the same server the RED drives appeared to give slightly better perforance in NAS. Maybe the NAS specific firmware isn't just marketing. For more, read on... I wanted to build a NAS server for windows sharing, iSCSI, and nfs sharing. I had an old 1U "pizza box" server with a core 2 dual CPU and 4GB of ram available plus SATA II (300MBPS) channels. I got one of the WDBMMA0010HNC-NRSN WD-red drives through the vine programs and I bought a second through Amazon to build this NAS server. This drive is the retail package. It came in a nice box with 4 screws for mounting and a little bit of very fine printed material which I didn't bother to read. If a "bare drive" is fine and you don't care about packaging you might want to consider another listing for the 1TB WD Red drives which may be at a lower price for essentially the same thing. The software I used to drive the NAS is the excellent (especially at the price) FreeNAS server. It installs on a USB stick of at least 2GB. My old box had several USB 2.1 ports, so no problem. I configured the drives in a RAID 1 mirrored array using software RAID (instead of the FRAID (fake raid) built into the motherboard chip set. I first built the server with the WD Red drives first and ran some casual tests with windows shares and iSCSI. Using windows network or iSCSI I could saturate my Gigabit Ethernet with no problem. Performance was not an issue. They ran great and I had no complaints over several days of use. This isn't too surprising as many NAS boxes use little Intel Atom processors. Next I did a comparison by replacing the WD Red drives with WD Black 750GB drives I had on the shelf. I didn't see much difference but I felt that copies of lots of small/medium files completed more quickly with the Red drives. Maybe the caching algorithm of drive was just better tuned for NAS on the Red drives. A plus is the Time Limited Error Recovery (TLER) which is an important part of drives that are designed for RAID deployment. And having a drive that is designed to be on 24X7 is great. I've switched back to the WD Red drives in my home-built NAS and I'll update this review as I live with the drives and report if there are any problems or notable excellence that stands out. Hope this bit of experience helps someone. Update: Dec 3, 2013 I have recently gotten a Buffalo LinkStation 420 2TB 2-DriveNAS Personal Cloud Storage and Media Server In comparing my home built FreeNAS system (on old core duo hardware) with two of these drives to the LinkStation with 2 Toshiba drives was interesting. The FreeNAS system with the WD NAS drives (both systems with RAID1) ran about 50% faster than the LinkStation. You can check my review on the LinkStation for more information about my comparison. The LinkStation might be a better option to get diskless for a very low price use these drives inside it. The small footprint and low power make it an attractive option. Bottom-line it seems there may be something to the NAS specific firmware of these drives.

Good drive. Poor shipping. The drive itself works fine. However the shipping was terrible. I ordered two 4T drives and a NAS. It took 2 weeks to arrive then one of those drives was damaged and in operable. I returned it and order another. The replacement came 3 weeks later. Just in original packaging with no over box or padding. Lucky this one worked but could have been damaged easily the way it was shipped. Definitely not what i expected from an Amazon retailer.

I rebuilt a failing TrueNAS server using four of these in a RAIDZ1. I'm using 2.5Gbps and the drives are plenty fast for a couple of file shares and as storage for a small home Proxmox cluster. They run cool and consistent between 22 and 31 degrees Celsius with minimal direct cooling. Do yourself a favor and label the drives with the SNs so you can easily identify a drive when one fails. I bought these to replace 6 year old WD Reds so they should be reliable and good for the price.

Been using this in my home synology nas for the last year and it’s been really good. No issues, great drives.

Reliability: I’ve been using the WD60EFRX 6TB drives in my QNAP TS-453A for just shy of 10 years, and honestly? I completely forgot they were still the original drives. That’s how quietly and reliably they’ve been doing their job—like the NAS equivalent of a dependable old friend who never calls attention to themselves but always shows up on time. They’ve been spinning 24/7 in a RAID 5 array, handling backups, media, and day-to-day tasks without a hiccup. Not a single SMART warning, not a whimper of protest, and no weird noises—just smooth, silent duty like clockwork. I only realized how old they were when I started planning my upgrade, and it hit me: these things have been running since before streaming 4K was even a thing. Western Digital nailed it with this one. If I could buy them a retirement watch, I would. But since I’m replacing them with the newer WD Red 10TB (WD101EFBX), I figured the least I could do is write a glowing eulogy—I mean, review.

I have a home NAS that is filled with WD RED drives. I wanted to expand the capacity, so I was replacing a 1TB drive, with this 4TB drive. Unfortunately, even with much time spend with support, I could not get my Synology NAS to recognize this drive. The belief was that the drive was not working. So I returned it (and purchased again. that drive did work as expected, right away). So I did just happen to receive a flawed drive. Would I purchase again: Yes Would I recommend to others: Yes

Good

Llegó bien embalado y funciona perfectamente, apenas hace ruido. Instalado en un pc de escritorio como disco de almacenamiento masivo.

Arrive well and fast. Performance wise is also is typically of WD quality.

Schijf gekocht voor de nieuwe NAS. Snel geleverd maar ik schrok van de verpakking: een kartonnen enveloppe met een enkele laag bubbel theater plastic om de schijf die verder enkel in een anti statische zak zat. Het pakket komt door de brievenbus en valt een meter lager op de vloer. Uitgebreid getest en gelukkig geen defecten gevonden. Dit is wel iets waar Amazon beter over moet nadenken.

This one has just replaced an old one which has been used constantly in my home media server since 2017. Nothing more than a confirmation of longevity of the old unit. I would expect the same from this one.
