How these two compare
Sequential throughput
Patriot P300 1TB is rated 2100 MB/s read and 1650 MB/s write; Seagate BarraCuda Q5 1TB, 2400 MB/s read and 1700 MB/s write. These are peak sequential rates over PCIe — the speed you would see copying one large file. For boot, app launches and everyday feel, random access matters more than this headline figure.
Price
Patriot P300 1TB lists at $145.99, or $145.99 per TB; Seagate BarraCuda Q5 1TB at $179.99, or $179.99 per TB.
Endurance
The makers warrant 480 TBW on Patriot P300 1TB and 274 TBW on Seagate BarraCuda Q5 1TB — how much writing each is rated to take before the endurance clause lapses. Most desktop workloads never come close, so read the two against each other rather than as a limit you are likely to reach.
DRAM cache
Patriot P300 1TB is DRAM-less; the catalog does not state whether Seagate BarraCuda Q5 1TB carries a DRAM cache. A DRAM cache holds the drive's mapping table — the index of where each block physically sits — so the controller places and finds data without an extra flash lookup. A DRAM-less drive borrows a little system memory (HMB) or a slice of its own flash instead, and is likelier to slow once a long run of random writes outlasts its fast cache.
NAND and warranty
NAND: Patriot P300 1TB's NAND is not stated and Seagate BarraCuda Q5 1TB uses QLC. The tier is bits per cell — SLC, MLC, TLC and QLC from one to four — trading density against endurance and sustained-write speed: QLC is cheapest per gigabyte, TLC the mainstream balance, and the denser the cell the sooner sustained writes taper. On the cover: Patriot P300 1TB carries a 5-year warranty, Seagate BarraCuda Q5 1TB carries a 3-year warranty. The length is the maker's own vote of confidence, and on an SSD it tends to track the endurance rating — a longer warranty usually meaning more rated writes.
