Western Digital 18TB WD Red Pro NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, CMR, 512 MB Cache, 3.5" - WD181KFGX

This is an excellent NAS hard drive with 8 TB of storage, specifically designed for home or small business NAS systems. Its stable performance, low noise level, and good energy efficiency make it ideal for backups, multimedia storage, or RAID configurations. Many users highlight its reliability and ample capacity for large amounts of data. Some mention that it can be a bit noisy during intense data transfers, but overall, it offers great value for money and reliable 24/7 operation.

So, here it is: the Western Digital 18TB WD Red Pro NAS Internal Hard Drive — aka the “Big Boy” of data storage. What can I say? It’s a hard drive. It’s quite big. Like, “I could bench press this if I really wanted to” big. But please don’t — it’s expensive. 18 terabytes of space means I could theoretically store every embarrassing photo, weird Spotify playlist, and downloaded PDF I’ve ever made. The digital equivalent of a hoarder’s dream garage. Installation was straightforward: slot it in, screw it down, pray to the tech gods it spins up on the first try. Spoiler alert: it did. No strange noises, no smoke, just pure, reliable mechanical magic. Pros: So much space, I could hoard cat videos for decades. Designed for NAS, which means it’s the responsible adult of hard drives — steady, dependable, and ready to work overtime. Quiet enough that I almost forget it’s humming away, plotting how to store my entire digital life. Cons: It’s heavy. Not “drop on your foot” heavy, but “maybe I should use two hands” heavy. No flashy lights or cool holograms, just good old-fashioned spinning platters. Does not come with a personal assistant to organize your files or delete your bad decisions. Final Verdict: ⭐️⭐️⭐️⭐️⭐️ – 5 stars. It stores data. It’s big. It doesn’t complain. Honestly, what more do you want from a hard drive?

I ordered the 26TB Western Digital Red Pro NAS internal hard drive, and it exceeded expectations right from the start. It arrived fast, was packaged securely, and installed without any issues. Once up and running, the drive performed exactly as expected—quiet, cool, and incredibly reliable. Transfer speeds are smooth, and it integrated seamlessly into my NAS setup. For large storage needs, backups, or expanding a home server, this drive is a powerhouse. If you’re looking for top-tier performance, huge capacity, and dependable WD Red Pro quality, this 26TB model is a fantastic choice. Would absolutely purchase again.

Works well, just very noisey on boot, coming out of sleep and when reading. Didn't notice my 8TB, but this one I definitely notice every time it's in use.

As someone who uses my NAS daily, I know how important it is to have a stable and reliable option for storage. I have been using these for years without issue. Great options for storage sizes and relatively quiet for a hard drive

I use this in an external hard drive caddy - one of the things that looks like a toaster an connects to the computer by USB 3. It works well and is as fast as can be expected for a drive of this specification in an extern caddy. The thing about hard drives is that your chances of getting a good one that will work well for years are huge. There is a trifling small chance you will get a dud that will fail after not much use. Happily, in this case I got a good one.

A nice addition to my NAS. Have a set that has been running continuously for over a year and a second set for several months now. If I had to complain about something, it would be that they seem a little on the loud side. The NAS is in the back room, so it is no bother. These WD Red drives are good for the price. The speed is good, storage capacity is ample. I expect many years of performance out of these drives.

Drive is/was DOA. Neither my NAS nor my PC would recognize it. My NAS didn't see it at all. My windows PC saw it as anew drive, but when I tried to initialize it I got "The request failed due to a fatal device hardware error". I know bad drives can happen, and not overly worried about this. I've scheduled a return and have already ordered the same drive again as it most closely matches the 12 other slightly older version WD 8 TB drives I have in my NAS already. This is to replace the 13th, which is having issues. I will update this review after getting and testing the new drive, assuming it works properly. But for now, I need to note the bad drive. Update: The replacement drive showed up fine on both my PC, and my NAS (which is what this drive was intended for all along.) Only had it a couple days so can't forecast long term health, but at least it can be used. I've updated from 1 to 3 stars for now. The annoyance of the delay and the 50% success rate means I don't feel comfortable rating it any higher. I may raise it later after more sustained use. As noted above, my NAS is entirely WD 8gb drives, and I've been very happy with them now for a long time. So overall I rate WD highly. Just not this particular experience.

I bought a pair of 10 TB drives and have used them in my NAS for more than 3 years now. Touch wood it is been a great experience.

Excelente duración, poco ruido .

Ho voluto provare la versione PRO , che ha una rotazione superiore rispetto al solito . Per quel che riguarda il prodotto in generale non ho nulla da dire .. gli hdd WD Red sono una sicurezza. Devo però esprimere un giudizio negativo sulla rumorosità , dovuta alla rotazione superiore . Ho il Nas sotto il mobile TV chiuso e nonostante tutto si percepisce il ronzio continuo del hdd....è parecchio fastidioso . Penso che in futuro acquisterò un Seagate che gira a 5900 per vedere se risolvo il problema rumorosità.

Ho acquistato questo hard disk per archiviare film e giochi. Certo non è veloce come un SSD, ma rispetto agli altri dischi meccanici ha 256MB di cache che lo velocizza parecchio. Il rumore è contenuto e non scalda. Western Digital è una marca seria e affidabile. Anche se l'uso consigliato è come elemento di unità RAID, quindi situazioni dove c'è una lettura/scrittura continua, io preferisco usarlo per effettuare miei backup e per parcheggiare collezioni di dischi audio, film, concerti, insomma come memorizzazione dati a lungo termine. Quello che mi ha fatto scegliere questo disco? La possibilità di avere in un'unica unità tutto quello che mi serve a un prezzo per Giga molto conveniente. Ricordatevi che UN SOLO disco non e' un backup, dovrete avere almeno DUE copie di quello che non volete assolutamente perdere (e possibilmente non nello stesso posto fisico). Ne comprerò presto un altro. PRO: GRANDISSIMO, NON C'E' (ANCORA) UN SSD COSI' GRANDE, NON E' TROPPO LENTO, E' CONVENIENTE CONTRO: NON E' UN SSD, COME DISCO PRINCIPALE CONVIENE USARE UN PIU' PICCOLO SSD
