Average Bench: 76.3% (381st of 956)

Based on 1,206 user benchmarks.  Model: ADATA SP920SS

The ADATA SP920 shares the same controller (Marvel 88SS9189), and for capacities over 256GB the same NAND configuration as the excellent Crucial M550. The lower capacity SP920 drives however have fewer NAND channels than the M550. Comparing the 512GB M550 and SP920 shows that the drives have comparable performance but at the 256GB and 128GB capacities the M550 has a significantly faster sequential write speed. The 256GB SP920 does have an average effective speed and it is priced below average so overall it represents reasonably good value for money. That said, there are both faster and cheaper SSDs available in the now both heavily saturated and extremely competitive SSD market. [May '15 SSDrivePro]
