While the speeds of graphics cards, memory, and CPUs continue to increase it seems solid state drive speeds have been bottlenecked for a while now.  With that we have seen storage start to move over to the PCI-Express bus as it is closer to the CPU and that brought with it the NVMe (Non-Volatile Memory Express) protocol.  NVMe drives are currently some of the fastest storage options out there for consumers and we took a look at our first NVMe product, the Intel 750, not that long ago.  Well now it is Toshiba's turn with their OCZ RD400.  Toshiba has turned OCZ into their "enthusiast brand" so new products will still hold the OCZ name, but they are indeed Toshiba products.  The OCZ RD400 has sequential read and write speeds up to 2600 MB/s and 1600 MB/s respectively.  Let's see what it is all about!
