Crucial BX500 Alternative Drive Comparisons
ADATA SU800 1TB 2.5-Inch SATA SSD
The ADATA SU800 expands storage to 1TB, giving you more than four times the room of the 240GB Crucial BX500. It includes an onboard DRAM cache buffer, which the BX500 lacks, helping sustain data traffic during heavy operations. Maximum sequential read speeds reach up to 560 MB/s, edging past the BX500 rating of up to 540MB/s. At 1.6 ounces, the SU800 is lighter than the 2.12-ounce Crucial drive, though slightly thicker at 0.28 inches compared to 0.27 inches. You give up the Micron brand ecosystem. Pick the SU800 if you need substantial space and dedicated DRAM caching for demanding SATA workloads.
INLAND Pro 120GB 2.5-Inch SATA SSD
The INLAND Pro provides 120GB of capacity, cutting the Crucial BX500 volume of 240GB in half. Its sequential read speed reaches up to 520MB/s, trailing the 540MB/s capability of the BX500. Both use 3D NAND and standard SATA III interfaces. The INLAND Pro measures 0.28 inches in height, making it barely thicker than the 0.27-inch Crucial enclosure. You give up storage capacity and slight read throughput compared to the original baseline drive. Choose the INLAND Pro if you only require a small, essential operating system drive for a basic setup and do not need extra room for local user files.
Addlink S20 512GB 2.5-Inch SATA SSD
The Addlink S20 offers 512GB of space, more than doubling the 240GB capacity found on the Crucial BX500. It integrates dedicated SLC caching to handle daily file transactions smoothly across SATA III connections. Both models share a 3-year limited warranty and standard 2.5-inch mounting form factors. The S20 enclosure stands 0.28 inches high, whereas the BX500 is 0.27 inches. You sacrifice the proven Micron manufacturing name attached to Crucial hardware. Pick the Addlink S20 if you plan to upgrade a desktop, laptop, or PS4 console where extra storage headroom and built-in SLC cache provide clear practical benefits over 240GB.
Silicon Power A55 1TB 2.5-Inch SATA SSD
The Silicon Power A55 delivers 1TB of capacity, providing over four times the storage space of the 240GB Crucial BX500. It features SLC caching technology to sustain write responsiveness, whereas the baseline BX500 relies on standard 3D NAND operations. At 1.76 ounces, the A55 is lighter than the 2.12-ounce Crucial unit, although its 0.28-inch profile is slightly thicker than the 0.27-inch BX500. You surrender Micron-specific branding. Choose the Silicon Power A55 if you need a high-capacity 1TB SATA drive for larger file collections or game installations rather than a basic operating system boot drive.
Crucial BX500 240GB 2.5-Inch SATA SSD
This version of the Crucial BX500 carries model number CT240BX500SSD1, directly mirroring the core hardware specifications of the CT240BX500SSD1Z original. You get identical 240GB capacity, 3D NAND architecture, and maximum sequential read speeds up to 540MB/s. Both share the same physical dimensions: 0.27 inches thin and 2.12 ounces in weight. Because internal components and SATA III capabilities match completely, you give up nothing in performance or physical fit. Choose this model when sourcing parts if you want identical Crucial BX500 specifications and speed characteristics under an alternative official product packaging code.
TEAMGROUP GX2 512GB SATA III 2.5-Inch SSD
The TEAMGROUP GX2 supplies 512GB of TLC 3D NAND storage, offering more than twice the capacity of the 240GB Crucial BX500. It features built-in DevSleep support, engineered to conserve laptop battery power by dropping consumption during standby states. At 1.76 ounces, it is lighter than the 2.12-ounce Crucial drive, though slightly taller at 0.28 inches versus 0.27 inches. You trade away the Micron-specific pedigree of the BX500. Pick the GX2 if you are updating a notebook computer where doubling storage space and lowering standby power draw take precedence over basic 240GB baseline drives.
