Pick the right IT-mode HBA for ZFS: LSI 9211-8i vs 9300-16i vs 9400 series. Flash firmware, avoid RAID controllers, navigate expanders and PCIe lanes.

Linux filesystem comparison: ext4 for safety, XFS for scale, ZFS for snapshots, Btrfs for flexibility. Pick the right tool for your workload.

ZFS tuning for flash: ARC sizing, recordsize, autotrim, sync modes, and SLOG advice, plus why defaults written for spinning disks waste an NVMe pool.

RAID-Z isn't just RAID 5 with a new name. Variable stripe widths, no write hole, and dRAID's distributed spares change the rebuild math entirely.

Run PostgreSQL 18 on ZFS for atomic snapshots, lz4 compression, and silent corruption detection. Tuning guide, backup automation scripts, and the real pitfalls.

Three popular NAS operating systems compared: TrueNAS Scale's ZFS, OMV's flexibility, and Unraid's mixed-disk magic. Which is right for your home lab?

Native ZFS dataset encryption vs LUKS under your pool, which layer to encrypt at, performance trade-offs, key management, and raw send/recv.

sanoid manages ZFS snapshot policies automatically, syncoid replicates them over SSH to remote pools, together they're the lowest-effort offsite backup strategy for any ZFS user.

Pipe ZFS incremental snapshots through WireGuard to a friend's NAS or a remote VPS. Encrypted in transit and at rest, no rsync.net bill or vendor lock-in.

ZFS is the paranoid fortress of filesystems. Btrfs is the scrappy upstart built into your kernel. Here's which one belongs in your home lab.
