The oldest NVMe SSD I have at home is a Samsung 950 Pro (the 256 GB version!) which I bought in late 2015 IIRC (and put on a ASUS Z170-A mobo, that already had a NVMe slot) and which has been in use that whole time (but mostly light desktop use): Percentage Used: 27% Data Units Read: 48,801,760 [24.9 TB] Data Units Written: 84,590,914 [43.3 TB] Power Cycles: 228 <-- only 228 power cycles in 11 years, that's about 17 days uptime every time I think Power On Hours: 37,153 <-- not sure about this one, this comes out at about 9 hours / day of uptime And after 11 years it's still going strong! Now it's not on my main computer anymore: I'm rocking a WD-SN850X (recommended here on HN when it came out) but the old Samsung 950 Pro is on the desktop computer my wife uses daily (and she WFH). [...]
well, let's just say I'm very glad I got it in June and ordered additional 2x32gb of ddr5-6000 on 31 August for $171, and an 8TB WD Black SN850X around the same time for $629. [...]
I have an MBP M4 Pro and a WD Black SN850x in an external TB5 enclosure and I easily get 6-7 GB/s
I self-host private git, notes, audio, photos and syncthing - basically everything I don't want to store in the cloud. Hardware is an old Fujitsu D3417-B, XEON 1225, 64GB ECC and a single 2TB WD SN850x. [...] Hosted are Gitea Immich Audiobookshelf Navidrome Flatnotes Syncthing and some other minor services. A Windows vm with USB passthrough is used for ripping audio CDs [1], which are then auto converted from flac to mp3 / m4b and integrated into audio services and syncing my iPod Nano 7g (yeah, I'm old). [...] Additionally Photos and documents via restic on an external Tasmota 500GB drive. [...]
I have two Framework 13 DIY, top of the line (Ryzen AI 9 HX 370, 96 GB of RAM, 2TB WD BLACK SN850X). [...] First of all, now I feel confident I can easily tinker with my laptop, open it and replace any components. [...] Some months ago my previous Lenovo X1 Carbon stopped charging and I was scared as hell. Sure, I have everything in version control and cloud drives blah blah blah but if it doesn't charge, it's dead. Sure, I can extract the NVMe (is it easy at all?) and rsync the data (for a faster recovery) but is that easy, feasible, can I do it on the go (X1 stopped charging while I was on a trip). [...] This is priceless. Other than this, build quality is higher than expected, and several other people said exactly the same when I showed my unit. [...] Nothing, it's my laptop and will be the next one. (Actually the next one may be cheaper, as I may only need to replace the motherboard, we will see)
[...] One very nice thing: the Samsung Pro 990 4TB has the exact same space (down to the byte) as the WDBLACK SN850X 4TB, so they can be replaced without any issues. [...]
[...] I use it as a "desktop" though and not as a laptop (as in: it's on my desk hooked to a monitor, never on my laps). [...] I don't know if it's the RAM on the 7700X or the WD-SN850X SSD or Linux but everything is simply quicker, snappier, faster on the 7700X than on the M1. [...]
I recently bought an n100 and within a matter of days got buyer's remorse and impulse-purchased an n305 to go right beside it, which is currently sitting with a wildly overpriced 48 GB stick installed and 2TB SN850X, it's an absolute joy perfwise and the absence of heat it generates. The only thing I'd reserve judgement on is the tendency to throttle. I haven't got far enough to characterize it, but it's not clear how much value those extra cores will add over the n100 with TDP settings tweaked down in the BIOS, and if leaving the n305 to run at max TDP, heat/noise/cost/temperature-related instability may start to become an issue, especially when packing other hot components like a decent SSD into the tiny cases they come in.
I use the following config: Fujitsu D3417-A Xeon 1225v5 64GB ECC RAM WD SN850x NVMe 2TB PicoPSU 160W with Bojiadafast Adapter All in all it costs about 200 bucks (Fujitsu Celsius W550), draws 10W Idle and has enough performance for a home server. [...] Docker containers I use: immich - photo backup flatnotes - my personal notes kavita - ebooks navidrome - music audiobookshelf - audio books jellyfin - video pihole - adblock stirling pdf - pdf editing Backup happens to an external usb drive with one small zfs bash script and a tasmota shelly plug (Switch on the shelly plug, wait until it is available, run incremental zfs sync: zfs send --raw -RI "$BACKUPFROMSNAPSHOT" "$BACKUPUNTILSNAPSHOT" | pv | zfs recv -Fdu "$DSTPOOL" To keep it save I also backup to my parents house regularly and the most important files via restic to an old Dell T20 as well as burn it on a blu-ray.

[...] It all feels so fiddly and sluggish while still being "not that cheap". [...] Paying 43 bucks for the whole thing - now asking myself if it is worth saving a few bucks and living with 100Mbit network speed, instead of spending 150 bucks and having 2.5Gig. There are so many (also "used") alternatives out there: - Fujitsu Futro S920 (used < 75, 10W) - FriendlyElec NanoPI R6C (< 150, 2W, - FriendlyElec Nas Kit (< 150, 5W, - Dell T20 / T30 (used < 100, 25W) - Fujitsu Celsius W570 (used < 100, 15W) My personal NAS / Homeserver: Fujitsu D3417-B Intel Xeon 1225v5 64GB ECC RAM WD SN850x 2TB NVMe Pico PSU 120 More expensive, but reliable, powerful and drawing <10W Idle.
[...] Installed WD Black SN850X 4 TB (WDS400T2X0E) on my Framework Chromebook. I’ve been using it for a month and a half now. [...]
[...] Since there are very different requirements, this might be interesting for many homeserver / NAS builders. For me personally I found my ideal price-performance config to be the following hardware: Board: Fujitsu D3417-B2 CPU: Intel Xeon 1225 V5 (better the also compatible 1275v6, but its way more expensive) RAM: 64GB ECC RAM (4x16GB) SSD: WD SN850x 2TB (consumer SSD) Case: Fractal Design Define Mini C Cooling: Big block no name, passively cooled by case fan Power: Pico PSU 120W + 120W Leicke power supply Remote Administration via Intel AMT + MeshCommander using a DP Dummy Plug I bought this config used VERY CHEAP and I am running Proxmox - it draws 9.3W idle (without HDDs). [...] Alternatively you could go for the following changes, but these might be even harder to get for a reasonable price: Boards: GIGABYTE C246N-WU2 (ITX), Gigabyte C246-WU4 (mATX), Fujitsu D3517-B (mATX), Fujitsu D3644 (mATX) Power: Corsair RM550x (2021 Version) Cheap used Workstations that are good servers are Dell T30 or Fujitsu Celsius W550. [...]
[...] I use it since before burntsushi (who's here on HN btw)'s ripgrep was shipped with Debian stable! [...] A NVMe PCIe 4.0 SSD (I'm using a WD SN850X which someone here recommended to me when I assembled my PC) is that fast and ripgrep too.
[...] I'm now using an OWC Envoy Express Thunderbolt 3 enclosure with a 4 TB WD Black SN850X and have no issues whatsoever. [...]

My current config: Fujitsu D3417-B12 Intel Xeon 1225 64GB ecc WD SN850x 2TB mATX case Pico PSU 150 For backup I use a 2TB enterprise HDD and ZFS send For snapshotting i use zfs-auto-snapshot So really nothing recommendable for buying today. [...] well too old or no longer available and the new stuff is either to pricey, lacks features (ECC and 2.5G mainly) or to power hungry. [...]
