Single SSD is Faster. A single SSD or a RAID 0 HDD setup, which is faster? This is probably the biggest question that most computer enthusiasts are wondering about. After quite a bit of research, I kept finding that the single SSD drive was quite a bit faster than the HDD raid 0 setup. Most benchmarks I found had the single SSD being somewhere around 25-50% faster than the RAID 0 HDDs.
If the CPU needs the same bit of data (a value from the same address), it will automatically look in cache first, which is much faster than RAM. As Arindam says, there is a hierarchy of cache in modern CPUs. There may also be normal (slow) RAM used as cache for hard drives, and also SSDs can be used as such.
