Sabrent Rocket Q 1TB vs Western Digital WD Green SN350 1TB
At least one of these has no price the site currently tracks, so what follows weighs specifications alone.

How these two compare
Sequential throughput
Sabrent Rocket Q 1TB states 3200 MB/s read and 2000 MB/s write; Western Digital WD Green SN350 1TB states 3200 MB/s read and 2500 MB/s write, both over PCIe. Sequential numbers like these describe large sustained transfers; the responsiveness you notice day to day tracks random access more closely than the peak figures do.
DRAM cache
On the cache question: Sabrent Rocket Q 1TB carries a DRAM cache, and Western Digital WD Green SN350 1TB is DRAM-less. The DRAM keeps the flash-translation table close, sparing a lookup on nearly every access; a drive without it leans on host memory or its own flash, which usually shows as slower sustained random writes rather than in the headline sequential numbers.
NAND, controller and warranty
On the flash itself: Sabrent Rocket Q 1TB uses QLC, and Western Digital WD Green SN350 1TB uses QLC. NAND tiers count bits per cell — more bits pack more capacity into the same silicon but shorten write endurance and slow sustained writes, which is why QLC sits below TLC on lasting performance even when the sequential numbers match. Controller: Sabrent Rocket Q 1TB uses the Phison E12S and Western Digital WD Green SN350 1TB uses the WD Polaris MP16. The controller runs wear-levelling, error correction and the mapping table, so it shapes sustained and random behaviour as much as the flash does — though the model name alone predicts little without testing. Sabrent Rocket Q 1TB carries a 5-year warranty and Western Digital WD Green SN350 1TB does not state one — the length the maker will stand behind the drive, and usually a proxy for the endurance it is rated to.
Which to buy
The site holds no current price for at least one of these, so it cannot call the buy on cost. Judge them on the specifications above — at the same capacity and interface, two drives usually part on things like the DRAM cache, the NAND tier, endurance and warranty, so weigh whichever of those the sections above report.
