ADATA XPG Gammix S70 PCIe 4.0 2TB Review
Cache
We test the cache by using a random data file generator and just writing endless data to the disk until it’s full, whilst monitoring the transfer speed. Like so many drives before it as long as you’re writing around 10GB it’ll be blisteringly fast, but once you pass 100GB in a single write things start to slow down. Curiously the XPG actually speeds up initially before dropping down.
