Hello!
I am getting the parts together for a tower server build. I plan on running Jellyfin, maybe dive into arrs and nextcloud for 2 users total, wireguard only for external access as it’s not the main focus for now.
Situation: if I have access to refurb/used 4TB enterprise HDDs at the same price as 1.9ish TB enterprise SSDs.
I’d take lower capacity as it is not that big of a concern for me rn. I want to have somewhat redundant storage of my documents, photos, but otherwise it’s not gonna be a giant media vault overflowing with movies.
Question: In terms of noise, shipping concerns and longevity, would you go with SSDs instead of HDDs? Is it lower maintenance?
I can of course buy spinners later if I find flash only to be restricting in any way, and add to the rig as needed.
Speed would not be an issue in any case. This is for TrueNAS scale, so zfs. I am planning to buy 3-4 disks now, and add more if needed in 6 months time or later.
I am eager to hear others opininons on this. Thanks!
My home server is equipped with SSDs. There’s a couple of reasons for that. The 2 main ones are Speed and Energy Consumption.
My server is placed in a different room of the house, so I’m not bothered with noise, but if it was in in my office, noise would be another reason to get the SSDs.
The only upside to HDDs is probably the GiB/$ you get. Otherwise SSDs are just as good or better these days.
My tower server is put away behind a wooden door. It has 1 fan that’s inaudible because it’s large and it runs slow, and it has 5 HDDs. I can’t hear them spinning. All I can hear through the door is the clicking of the HDDs’ heads, and only when it’s quiet around.
I would go with HDDs again. Cheaper per TB and Ionger life.
Failure rates for sdd are better than hdd but generally not by a lot. I’ve read that hdds can have a higher “crib death” where new drives have a higher failure rate, but after like a year they are solid. Unless you’re buying thousands of drives you’re unlikely to notice though.
I’ve never heard of “noise” being an issue for an hdd - especially if you have it in any sort of enclosure. If you’re not sitting right next to it you shouldn’t notice.
The biggest differences are performance and cost. If you want speed go ssd. If you want cheap go hdd.
My desktop systems run ssd where performance really matters to me. I get hdds for my file server where I want bulk storage.
The noise is only an issue because of how small my appartment is. I can’t really isolate noise in here. I would think it also depends on which drives I get. I read that some are louder than others.
Ah - this is true it can depend on the drive. The biggest variation tends to be in the loudness of the ‘clicking’ as the head moves. Older SCSI drives were (in)famous for how loud that could be. For the most part it’s a light hum of the motor. In my systems the case fan’s are much louder though. I suppose it’s a personal preference.
It’s generally at the “whisper” level or lower. But thinking about it being in my living room I could see it potentially being an annoyance compared to a silent drive. Depending on where it is, how enclosed it is, etc.
I have very recently acquired 4x18TB Seagate Exos drives for a fresh server. I parked them in an old case I had lying around where i was barely able to secure them all with screws, and cooling was especially problematic. Noise was horrible. standby noise was already audbile in the entire room. and when writing data while parity calculations were running, you could hear it in the entire apartment. The noise travelled through the wooden floor into every other room.
I have now moved the server and the drives into the fractal define 7 case. the drives rest on specially made rubber bearings that came with the case. the sides are noise isolated. the system is running with 6 fans total, 3 of which are 120mm corsair fans repurposed, and 3 are 140mm from the define 7. the server is now close to noiseless. vibrations do not rattle the case as with the old one. the rubber bearings isolate most of the vibration anyways. all that is left is a bit of head clacking, which gets isolated away from the case sides.
long story short: the drives are only half the story. you need a proper enclosure that is noise isolated. the define 7 is comparatively huge, but it gives you immense room to grow and was truly a godsent regarding noise.
Thanks for the insights on the case and drives!
I have an old Silverstone case with about 6 of the old style 3,5" drive mounts and 3x5,25" bay. Originally I had a Samsung 1TB drive in it (which is still kicking around somehow pulling torrent drive duty) I remember it being louder in that case then in my new one. So I’ll have to test it out. If i can get my hands on some rubber bearings and if they help any at all.
I am not planning to go that big on storage for now tho. It sounds like serious work. I am doing this so I can be more comfortable. Aside from updates, I want to dial it in once and forget it unless I need to touch it.

There’s your first problem.
I have a bunch of WD HDDs (9) in my Fractal Design Define R7 case sitting on top of my desk, about 2ft away at ear level, and can barely hear them. If anything the hum of the fans is what I can hear most (though still quiet). I have a security camera NVR with a little 40mm fan 12ft away on top of a high shelf in my office and I can hear it over my server by quite a large margin.
Even if rebuilding it today, I’d go for HDDs as you can’t buy 12, 14, 18TB, etc SSDs for a couple hundred bucks and you won’t really gain any benefit using SSD over HDD as reading large movie files from a disk isn’t going to saturate the drive cache and you won’t be dealing with random seeking.
You said you might upgrade all the drives in the future but how (2nd NAS?) and what will you do with the old ones? 4x4TB is going to fill up pretty fast especially when you’re first starting out and eager to add new titles.
Failure rates for sdd are better than hdd
I’m curious on where did you find this. Maybe they have lower DOA rates and decreased chances to fail in the first year, but SSDs have a limited usage lifetime / limited writes, so even if they don’t fail quickly, they wear out over time and at first they have degraded performance, but finally succumb in 5 years or less, even when lightly used (as in as OS drives).
To avoid DOA / first year issues with HDDs, just have the patience to fully scan them before using with a good disk testing app.
Backblaze and other “bulk storage providers” tend to release reports every-now-and-then about the lifetime of their drives (it’s important for them to understand the costs). Here’s one such Backblaze Report.
At this point we can reasonably claim that SSDs are more reliable than HDDs, at least when used as boot drives in our environment.
Holy shit, I stand corrected, those graphs speak for themselves. Bookmarked for future stats.
LE: Well, there’s also the section about average age of failure in their newest report: 2 years and 7 months for HDDs, 14 months for SSDs.
The write cycles shouldn’t really be an issue for a home NAS because you’re not erasing and rewriting over and over. For commercial projects, where logs, security video, or rotating data needs to be stored and erased hundreds of thousands of times.
True, but it depends from person to person and it counts if you have a small or big drive, how often you watch and rotate your media, how large the media is. If you only have a 1TB SSD, and often download and watch blue-ray quality, 20 movies will fill it. It won’t be long until the same blocks get erased, no matter how much the SSDs firmware tries to spread the usage and avoid reusing the same blocks.
Anyway, my point is, aside from noise and lower power consumption advantages, I wouldn’t use SSDs for a NAS, I regard them as consumables. Speed isn’t really an issue in HDDs.
Would you suggest some good testing app? I just use crystal disk info to see the stats. Never ran a test as such.
I use Hard Disk Sentinel, it’s not free, but it also monitors drives in Windows so you have an early warning at the first sign of issues. Also logs historic data (writes, temperature, etc) and displays them as graphs.
even consumer SSDs have around 1500 TBW (Terrabytes written) per TB until warrenty excludes any failure
which means you could write for example every day for 10 years 400 GB on a 1 TB SSD
this is already a very low estimate, most SSDs do better
anyway OP mentioned enterprise SSDs which can write 1.0x or 2.0x it’s own size every day for 10 years
I’ve never heard of “noise” being an issue for an hdd - especially if you have it in any sort of enclosure. If you’re not sitting right next to it you shouldn’t notice.
No. I can’t stand the noise of HDDs.
My home server is a NUC inside an Akasa Turing fanless case with an 8TB Samsung 870 QVO SSD for my file shares. Works great and it’s completely silent.
It should go without saying that routine, off-site backups are an important element of server administration, regardless of drive type. Mine are completed monthly, and critical data (docs, keepass databases, etc.) is also synced across multiple devices using Syncthing.
I don’t plan to neglect backups. Currently I use Syncthing as well, but only between non-redundant storage locations, so I have duplicates. Like phone pushes photos to pc or laptop, those sync them between each other. Important docs that I can’t lose are also on all 3 devices.
And I plan to keep the local storage of mission critical data around on some clients at least. I just want to have a central, more robust, redundant system where one or 2 disks can fail without my data being gone or corrupted.
SSDs have no moving parts so they will make no noise and generally be more resilient than HDDs. They are really superior except when it comes to the price.
