What is the difference between pure SSD vs SSD cache? I am viewing a VPS offer and they offering both features but I am not sure which is better. I see SSD cache seem cheaper a bit and it can help my site to load faster? I would like to hear your advice which option should I select. Thanks

Pure SSD is already a "marketing" word, because a provider use SSD storage or do not use SSD storage.
SSD cache is cheaper because it use several hard drives with some SSD to cache content.

For example, 2x3TB of SAS disks (faster than SATA, but really slower than SSD) and 2x800GB SSD cache.
With price of SSD nowadays, it doesn't make sense to use something else than SSD for web hosting.

I thought it was normal VPS SSD and everyone often use it. But for a few providers, they added "Pure" to make their VPS a higher level :D

It is cheaper but it is faster? because I see they used "cache" in this term.

For example, 2x3TB of SAS disks (faster than SATA, but really slower than SSD) and 2x800GB SSD cache.

Agreed, always SSD for web hosting!

All the cache does is take a list of frequently accessed files and move them to the SSD drives, so these few files are delivered faster. For example, most index (index.php, index.html, etc) files will be moved to the cache as they are most often accessed file as the homepage is loaded more often on a website then any other pages.

So this makes the initial load of the website be faster, but internal pages be a little slower.
