I would like to see what the overall benefit is using this product on an everyday home user level. And if possible maybe a paragraph for us less technically gifted to understand in layman terms what it does. I understand that it speeds things up but am fuzzy on just what it does over and above a regular SSD that used for running the OS. In other words does it speed up the overall usage even using HDD as storage? Is it something that 'hot rods' the CPU? See what I mean.
I'll see if I can break down some of the advantages into simpler terms:
First up, the big difference is in the main 'cpu controller' of the drive. Most drives have a controller which will have between four and eight lanes to write data to the individual NAND chips. Obviously, the more lanes the controller has, the faster it can send out data. The one in this particular drive doesn't have four, it doesn't have eight, it has EIGHTEEN. This means it can dispatch more writes (more than 2x) over even the faster SATA eight channel controllers.
Next is NVMe vs SATA/AHCI. NVM Express is a reworking of the protocol on how the OS interacts with the drive. With a traditional AHCI setup, you have a single command queue which can hold 32 commands that are awaiting execution. With the NVMe, it has 65,000 queues which can each hold 65,000 commands awaiting execution. This means the drive queues will always remain full, and the drive will never be sitting 'idle' waiting. As fast as the CPU can fill the queues with commands and data, and face it, CPUs are operating at a far higher level than the drives, the drives will have data to read/write. This alleviates some of the idle time.
Last is that the NVMe drives use PCI-e lanes exclusively which are much faster for transfer than SATA. SATA has a maximum throughput of 6Gbits/second. PCI-e (v3.0) lanes have almost 8Gbits/sec throughput -per lane-. So, an NVMe drive which utilizes an x4 lane configuration has a throughput of around 32Gbits/sec, or around 4GBytes/sec throughput.
So - by putting a beast of a controller with a lot of channels, a big heatsink to keep it cool, on an x4 PCIe lane and using the latest low-latency protocols, they've put together a very fast drive.
As for it being useful for your typical user, heck, even a power-user, it's not really what you would ever need. I have a Samsung 830 SATA drive and it's two generations back and it's still stupidly quick.
