HDDs are the backbone of my homelab since storage capacity is my top priority. With performance already constrained by gigabit Ethernet and WiFi, high-speed drives aren’t essential. HDDs can easily stream 8K video with bandwidth to spare while also handling tasks like running Elasticsearch without issue. In my opinion, HDDs are vastly underrated.
- shikharbhardwaj 2y agoI run a hybrid setup which has worked well for me: HDDs in the NAS for high-capacity, decent-speed persistent storage with ZFS for redundancy, low-capacity SSDs in the VM/container hosts for speed and reliability.
- cshores 2y agoSame, I run my containers and VMs off of 1TB of internal SSD storage within a Proxmox mini PC(with an additional 512gb internal SSD for booting Proxmox). Booting VMs off of SSD super quick so its the best of both worlds really.
- fmajid 2y agoYes, those workloads are mostly sequential I/O, that HDDs can still handle. Most of my usage is heavily parallel random I/O like software development and compiles. You also have the option of using ZFS with SSDs as L2ARC read-cache and ZIL write-cache to get potentially the best of both worlds, as long as your disk access patterns yield a decent cache hit rate.
- cshores 2y agoI do something similar as well for my primary storage pool appliance of 28TB available. It has 32GB of system ram so I push push as much in to ARC Cache as possible without the whole thing toppling over; roughly 85%. I only need it for an NFS end point. It's pretty zippy for frequently accessed files.
