I'm using a Direct-Attached Storage (DAS) system with five drives, plus an additional external drive in its own enclosure. I'm looking for a utility or software that can help me monitor and assess the health of these drives so that I can be proactive about replacing any that might fail in the future. What are your recommendations?

You might want to check out S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology). If you're on Linux, the tool smartctl can help you read the S.M.A.R.T. data from your drives. It's a reliable way to get a sense of their status.
If you want to keep tabs on your drives, consider using DriveDX. It does a pretty good job of estimating drive health. I've had a drive that reported average health for years, but it hasn't failed yet. Just make sure you have a solid backup plan in place, like the 3-2-1 strategy, and you should be fine just waiting until a drive actually fails.
I recommend SpinRite if you're looking to diagnose your drives. It's been around for a while and can effectively identify issues before they lead to failure.
I have a Synology NAS, and it relies on S.M.A.R.T. too. However, I had a Seagate Ironwolf drive fail unexpectedly the other week with no warnings at all. Luckily, I had my backups in place, and redundancy saved the day. So while monitoring is helpful, don't forget to prioritize backups.
If you even have a hint that a drive might be failing, just swap it out. Storage is so cheap nowadays that it's better to be safe than sorry!
Honestly, S.M.A.R.T. is all you really need. It provides enough data to keep an eye on your drives. Also, if you’re using NVMe drives, they provide a whole lot of data now thanks to updates in management tools. It's super helpful but not always necessary to dig too deep.
Yeah, I've noticed NVME drives give a ton of info. Just making sure your backups are good is crucial!
