I need to replace a old dying 480 GB Intel S3500 drive in my ZFS array. I'm okay with my current performance and disk space. I'm not in a rush to upgrade. In the olden days before 2021 and Chia's arrival on the scene, I'd just pick up a couple more used S3500's for $50-75 a pop on eBay, but now...

XenServer 7.3: Changes to the Free Edition About four years ago XCP (Xen Cloud Platform) essentially the free version of Xenserver, was merged with "normal" Xenserver after it was opened sourced. This was awesome and pretty much all the Xenserver features were now free. Excellent for a hobbyist...

I'm thinking about getting a couple of 4 or 6 bay 2.5" to 5.25" mobile racks for my NAS to hold SSDs. All my 3.5" spinning rust lives in my DAS enclosure. I leaning towards Icydock's Express Cage over their Tough Armor line primarily because of price; but is there any reason I should splurge on...
