Our Verdict

The Silicon Power A55 2TB offers the lowest $/GB among 2TB drives in this batch at $0.099/GB — $47.08 less than the Crucial BX500 2TB and $76.48 less than the WD Blue SA510 2TB. Sequential reads reach 550 MB/s and writes 500 MB/s; TBW endurance at 600 matches the WD Blue SA510. The critical caveat is buyer confidence: 120 Amazon reviews is the thinnest signal in this entire batch, by a wide margin. Silicon Power is a legitimate Taiwanese manufacturer with a long track record, but limited real-world feedback on this specific model means less certainty about consistent quality and RMA responsiveness. For primary drive use in a SATA-locked system, the WD Blue SA510 2TB ($273.55) with 11,973 reviews and a 5-year warranty is the significantly safer choice. For secondary bulk storage — game libraries, media archives, backups — where the drive is not the single point of failure, the A55 2TB's $197.07 price is a genuine advantage. Right buy for: secondary bulk storage in SATA-compatible desktop builds where cost is the priority and the low review count is an acceptable trade-off — not recommended as the sole primary drive until buyer confidence improves.
