I am planning to sync an archive node for research purposes and am preparing to buy the hardware. How does the read/write speed of the SSD affect the sync speed? Is 500 MB/S enough, or would an upgrade to a faster, more expensive SSD improve the sync speed?
And more generally: Where is usually the bottleneck for sync speed?
And on a related note, does it matter if the storage space is split accross multiple SSDs? Can geth/partiy handle this automatically?
