XPG SPECTRIX S40G: 256GB vs. 512GB vs. 1TB vs. 2TB vs. 4TB

The XPG SPECTRIX S40G RGB PCIe Gen3x4 M.2 2280 Solid State Drive is available in five different capacities as you will be able to choose between 256GB, 512GB, 1TB, 2TB and 4TB. In addition to the amount of space provided, these storage drives offer different performance speeds. You can find out what the differences are in this comparison guide between these five SSDs.

Quick Summary

The 1TB, 2TB and 4TB XPG SPECTRIX S40G SSDs are the best preforming out of this group with the fastest maximum sequential reads, maximum sequential writes and maximum random writes. The 512GB version is slightly faster at maximum random reads although it lags behind the bigger capacities at CDM (QD64-T1) sequential writes. The 256GB XPG SPECTRIX S40G is generally the worst preforming out of these storage drives.
