Edward Stewart said:It’s the same story... the bottleneck is going to be the network rather than the drives themselves (1 Gbps is theoretically 125 MB/s, though in practice you're looking at 110-115 MB/s on a solid network setup with decent NICs and cabling).
Seagate IronWolf drives are a perfectly fine choice. You might consider a Toshiba N300 (instead of an X series), and since Western Digital seems to struggle a bit with their Red line lately, I'd suggest sticking with the Red Plus—that's what should count as the "real" Red series.
What's the intended role for this NAS? Are we talking about a dedicated backup solution or just a general file server?
I ask because RAID isn't actually a backup; it's just redundancy to ensure you don't face downtime if a single drive fails. If you truly want a backup strategy, you might want to aim for a 4-bay Synology or QNAP unit, allowing you to add another drive (or a pair) to automatically back up your "primary" RAID1 set. If budget is a concern, a 3-bay QNAP TS-328 would work well for a 2+1 configuration.
File server.
I get that RAID isn't backup, especially if it's sitting in the same office, but we don't need more than 4TB. Dropping two drives into RAID just so we don't lose everything if one dies isn't a massive investment. Sure, 4x4TB in a 3+1 setup would be better for redundancy (giving us 12TB), but we don't need that much space.
If we end up needing raw storage later, we can just slap a hard drive into one of the PCs; right now, we're strictly SSD.
If we need more capacity down the road, we can grab a 4-bay unit for the office and move this 2-bay one home to set up some kind of remote backup. I think Synology can handle that.
The network is basic, nothing fancy, but everything is hardwired—no WiFi. Speed isn't a huge deal; we're talking about moving a few GBs at a time. Whether it takes five seconds or a minute doesn't matter to us.
What's the real difference between Toshiba N300, X300, and IronWolf?
P.S.
Just double-checking—does that Synology model support RAID 1 without any weird fine print?
Does anyone know if there are recurring subscription fees, or is it just a one-time purchase?
Basically, I just need standard RAID 1 where one disk mirrors the other.
