Western Digital 500GB WD Black Performance Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, 64 MB Cache, 3.5" - WD5003AZEX

I am using this hard drive to play FLAC and WAV files on a KDlinks A400 media player. I consider myself to be something of an audiophile and I love good quality audio. The hard drive that I had been using prior to purchasing this WD Black was the Seagate Barracuda ST2000DM006 (A 2TB hard drive). The Seagate was solid and reliable for roughly two years and I had no complaints.The reason I decided to upgrade to the WD Black 6TB hard was because it was specifically made for multimedia and I wanted to ensure I was futureproof with regards to available hard drive space, so I decided to splurge on the WD Black.When I initially installed the hard drive in my A400, I was disappointed, because the sound was bright and shrill sounding. However, I heard all sorts of detail in my music that I never heard before and overall, the volume was louder as opposed to how the Seagate sounded, so I was a bit conflicted. I had to change the settings on my receiver (Pioneer SC-79) to try to remove that bright and shrill sound. There were a few factory settings on the receiver (Upsampling, Hi-bit32 are what I remember) that I had to turn off or to the lowest setting because they were processing the sound and making it sound artificial along with it sounding bright and shrill.These changes made it sound better, but it was still bright and shrill. I was really disappointed in the WD Black, but I remembered that some electronics require a break in (especially for audio purposes), so instead of giving up and returning the hard drive I figured I'd keep it and hope that it would break in.After about 90 days (not 90 days straight without shutting it off, but just playing it whenever I had time to listen to music or wanted music playing in the background), I noticed a magical thing.One morning, I sat down and turned it on and I noticed for a few hours that I did not get up because my music was sounding especially good. My music was extremely clear, the music had excellent detail (far more than the Seagate) and the volume was louder than the Seagate. The sound coming out of my speakers was something I was not prepared for (in a good way).I figured maybe I was just in some sort of a good mood and wanted to listen to music. Well, I made it a point to turn on my system for the next few days as time permitted and it sounded so much better (as opposed to Day 1) to the point of not wanting to get up and move on with my day.Another observation I noticed after the break-in is that the music has a "darker background". it's hard to describe what I mean but think about it like this. If you know what "white noise" is in the background, this hard drive seems to deliver less of that sort of sound. You hear more of the artist and instrumentation.It even made the difference between FLAC files and WAV files less pronounced. What I mean by this is that some albums I have ripped in both FLAC and WAV. WAV is the absolute best sound (between the two), but FLAC is close. it was far more noticeable on the Seagate drive, but less noticeable on this WD Black.In closing this review, if anyone is buying this for audio purposes, I suggest exercising some patience with the break in and if you are using a receiver, turn off anything that is processing the sound (similar to what I mentioned above). The audio output from this hard drive is pure. Read the owners manual and find any audio processing settings that are turned on as a default. There may be some things you leave on and you may also have to do some EQ adjustments, bass, treble, etc. but the result is well worth it. Exercise some patience with your receiver and you will be rewarded. As for my A400, there are some settings on that for optimal audio output that I'll be covering in my updated review on that whenever I get around to it. It is seriously a good piece for music.I did NOT expect anything special from a higher end hard drive other than available storage space, but I have been pleasantly surprised and I no longer regret my purchase as I did on Day 1. I highly recommend this hard drive for audio purposes. in fact, I cannot recommend it enough.Hope this helps with your purchase decision.

I needed a bigger HDD for the huge influx of 4K footage I'm working with. Got it in a cardboard box and a non-static/spill-proof metallic sleeve. Two plastic shock absorbers were located at the top and bottom of the drive.Date of manufacture was dated 20 FEB 2022. Looks like they're pushing in the new stuff now.Installation was easy, just crack open the PC case and slip it into the rack. I knew about the noisy reputation that WD Black Drive's had, so I ordered a couple of noise-isolating screws and rubber washer to help mitigate the impending cacophony. After slamming everything together, I shoved it all into the PC.Storage size and transfer rate is top-notch, I can both watch and edit 4K movies with no trouble at all. The only problem (which is honestly a non-issue for me, but maybe not for you) is the noise it makes. Every so often, maybe every 5-10 seconds the disk head moves and you can hear a slight "thunk". You get used to it after a while, and this IS a performance drive, so noise like that is to be expected. Might be a bit jarring to people who weren't around when your computer sounding like an old muscle car starting up was standard.When going through heavy loads, the HDD spins to a high speed, but thanks to those noise-isolating screws and washers, I barely hear it. And since I'm only using this drive for editing, when I'm not editing Windows automatically turns off the drive so the "thunking" isn't around unless the drive is on and in use. No "scratching" or similar noises have been heard from the drive yet, and I've been using it heavily since Day-1. Only Whirling of the disks and the every present "thunk".This will give you good storage and speed with the only trade-off being noise. Keep that in mind as you eye that "Add To Cart" button.

This drive has been great. I used a guide on the internet and this drive replaced the 2TB drive in an older Apple Time Capsule router. so I could continue automatic and easy backups with my computers getting ever-larger. With a couple laptops and a desktop I find the built-in Apple solution on their own router the easiest for backing up and it's been working wonders. I have 5x the space and better speed of backups. I also put a couple of folders on there for storage of files that I don't often access or want all the computers in the house to have access to.I'm a year in and the drive is responsive, seeks quickly, and data transfer is speedy when connected directly to the router and over the wifi network. I notice the noise but only when the drive initially kicks on and starts the backup process or accessing files after it's been idled. Sometimes during the backup it'll make a few misc. electronic working noises. This is nothing like the days of yore though and for a 10TB, 7200rpm drive I find it acceptable. This is a great solution to needing more space from the older equipment. WD has always been reputable and I'm glad I spent a little extra on this drive. If I ever go to a NAS or other directly connected storage devices I'd considering a couple of these for their performance. Hoping for longevity.
