Crucial BX500 1TB vs TeamGroup CX2 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
Crucial BX500 1TB reads at 540 MB/s and writes at 500 MB/s; TeamGroup CX2 1TB reads at 540 MB/s and writes at 490 MB/s. Both ride the SATA bus, which caps sequential transfer near 550 MB/s in either direction — the ceiling every SATA drive works against — so what more decisively separates them is sustained and random behaviour, the DRAM cache, and endurance.
Endurance
Crucial BX500 1TB is rated for 360 TBW and TeamGroup CX2 1TB for 200 TBW — the total the maker warrants you can write over the drive's life. A typical desktop writes only a few terabytes a year, so either rating is many years of headroom; the figure matters mainly as a relative signal of how hard each is built to be driven.
DRAM cache
On the cache question: Crucial BX500 1TB is DRAM-less, and TeamGroup CX2 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: Crucial BX500 1TB uses TLC, and TeamGroup CX2 1TB 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: Crucial BX500 1TB uses the Silicon Motion SM2259XT and TeamGroup CX2 1TB's controller is not stated. 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. Crucial BX500 1TB carries a 3-year warranty and TeamGroup CX2 1TB carries a 3-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
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.
