It will also influence what RAID card and case you choose later in this guide. You need to decide if you’re using SAS-6G (6Gb/s transfer speed) or SAS-12G (12Gb/s transfer speed) as they vary considerably in price. I’ll show you how to get brand-new SAS drives on the cheap. I will be using enterprise-class SAS hard drives rather than desktop-class SATA drives because SAS ( Serial Attached SCSI) is faster, more reliable, and built for RAID arrays (see HP’s take on SAS vs SATA). See this comparison of Hardware vs Software RAID. In my early days, I used software/BIOS RAID for my workstation and had endless troubles with disks falling off the array with disastrous results, so I don’t recommend software RAID. Add to that a nice big cache and battery backup, and it’s a no-brainer. For a home/office server, hardware RAID is so far ahead of software RAID it’s almost incomparable. I’m using a dedicated hardware RAID card in this tutorial rather than the motherboard BIOS to configure software RAID. That being said, I am always here to help and if you have any questions about the gear I link to, please email or comment before purchasing. You will need at least some experience building PCs and understand technical terms to complete this guide. You can buy expensive off the shelf systems with or without included hard drives, but they’re not a patch on the system I will show you today plus, it’s way more fun building your own NAS server!Īdvisory: This is an intermediate level tutorial. Having your own home or office NAS server is a great way to back up files, stream movies/audio, and share files on your local network.
