Article Snippet: " The 1TB version of the P1 NVMe SSD definitely offers more performance versus the 500GB model, and can keep the write speeds up for even longer, thanks to more SLC buffer (12GB versus 5GB on the 500GB drive). The increased DDR3 buffer also seems to come into play but expect a visible speed drop when writing large files to the drive. If the drive is operated in mainstream, home computers you won’t observe this limitation, but in production workstations were data changes frequently, the TLC write speed limitation will become more evident.
