Solid state drives continue to get faster, with PCIe 4.0 variants leading the pack nowadays. Of course, most PCs don't have PCIe 4.0 support, so these ultra-fast drives are reserved for enthusiasts and those with brand new computers. If you have such a cutting-edge PC, you will probably want to get a PCIe 4.0 SSD to maximize your performance. True, it is largely for bragging rights and benchmarks, but you might as well go for the best if the difference in price isn't totally obscene.
Today, KIOXIA unveils its latest solid state drive. Called "BG5," it uses PCIe 4.0 x4 to achieve up to 3,500 MB/s read and 2,900 MB/s write. Yeah, this DRAM-less SSD is actually a bit slow compared to other PCIe 4.0 drives, but it does have a very cool feature -- it is being offered in the M.2 2230 form factor. This means it will fit inside Microsoft's all-new Surface Pro 8.
