It's true, Von only uses SSD NVMe and SSD storage.
With new technology being introduced yearly, it may be confusing as to what’s what. Here is a break-down between the different storage drives available:
- SSD NVMe is, more or less, 2x – 7x times faster than SSD.
- A pure (or 100%) SSD consists of no platter / mechanical hard disk drives.
- SSD-Cache features both mechanical hard disk drives and a single solid state drive in RAID 10 array.
- A mechanical hard disk drive (HDD) is your traditional, standard super cheap storage.
Sorted from most performance to least, and often most expensive to least is SSD NVMe, SSD, SSD-Cache than HDD.
Don't let all the fancy hipster names and synonyms confuse you. There are, in reality, only a couple different types of hard drives (HDDs).
SSD cache is fast, but it isn't faster, nor performs better than a server with SSD drives. There are millions of servers in data centers using antiquated technology, so being creative and recycling hardware is smart. People can get great value if performance is not a top priority.
Some random, but perhaps interesting notes:
- Rumor has it SSD is not as reliable and may fail more often than traditional HDDs.
- SSD cache will use regular hard drives to store inactive data, while SSD is only used to store frequently accessed data.
- Using RAID array is smart, you can have more reliable storage (failure rate is lower in RAID array)
- If you require ALOT of storage space, consider a provider offering SSD-cached instead of HDD.
