[M] Silicon Power P34A80 PCIe 3x4 M.2 2280 1TB SSD Review
 

The 1TB version of the P34A80 SSD does not disappoint at all and in many cases, we have seen even higher read speeds than its 512GB version counterpart. The caching is improved thanks to the double capacity of RAM and well optimized firmware and after the SLC portion gets filled up, we can expect write speeds hovering around 1GB/s. One extra fact to consider is that this product is offered with no less than 5 years warranty, quite enough for a consumer-oriented SSD!
