How these two compare
Sequential throughput
fanxiang S880 2TB S880E states 7100 MB/s read and 6600 MB/s write; Sabrent Rocket 4 Plus 2TB states 7100 MB/s read and 6600 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.
Price
fanxiang S880 2TB S880E is $299.99 ($150.00 per TB); Sabrent Rocket 4 Plus 2TB is $569.46 ($284.73 per TB).
DRAM cache
On the cache question: the catalog does not state whether fanxiang S880 2TB S880E carries a DRAM cache, and Sabrent Rocket 4 Plus 2TB carries a DRAM cache. 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: fanxiang S880 2TB S880E uses TLC, and Sabrent Rocket 4 Plus 2TB uses TLC. 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: fanxiang S880 2TB S880E's controller is not stated and Sabrent Rocket 4 Plus 2TB uses the Phison PS5018-E18. 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. fanxiang S880 2TB S880E does not state one and Sabrent Rocket 4 Plus 2TB carries a 5-year warranty — the length the maker will stand behind the drive, and usually a proxy for the endurance it is rated to.
Which to buy
Against the other, fanxiang S880 2TB S880E is even or ahead on every tracked measure and behind on none, which is the one case where the choice needs no compromise.
