This won’t work for every use-case, so adapt it to your personal needs.Hell, the 1TB drives I use in the guide were free with the HP S01 I recently bought. HDDs are cheaper per TB than SSDs by a huge margin.Reducing the responsibilities of your SSD cache will increase its performance.They are cheap and will prevent SSD wear. Smaller 10k/15k RPM HDDs in RAID0 are plenty fast for unpack directories.HDDs generally sequentially read/write much faster than GbE, meaning this is ideal for large files such as media.Also, there’s no point in writing certain files to a SSD cache if the performance will be the exact same writing to a HDD cache instead. Sure, there are high endurance SSDs (and I always recommend them), but they are often more expensive than “normal” SSDs. If you can limit writing to your SSD, it will last longer. SSD endurance is something that should be on everyone’s radar.I’m not suggesting ditch your SSD cache entirely, I haven’t done that on any of my servers.
Hey everyone, this will be a quick overview of how I use HDDs with multiple cache pools.
