A Wider Trend: The FanXiang S660 is part of a larger trend in the SSD market. High-capacity SSDs at budget-friendly prices can sometimes struggle to deliver top-tier performance. Some of the fastest SSDs available, like the Samsung 980 Pro, tend to max out at 2TB capacity and offer exceptional read/write speeds of up to 7,000MB/s. In contrast, the FanXiang S660 4TB manages reads of 5,057MB/s, which is respectable. However, its write speeds, averaging around 406MB/s, may be considered subpar for an SSD.
Performance Realities: Serve the Home’s testing, conducted using CrystalDiskMark and ATTO benchmarking software, reinforced the performance disparity. The FanXiang S660 exhibited read speeds of 6,738MB/s but recorded dismal write speeds of just 365MB/s. To exacerbate matters, write speeds dropped even further to 180MB/s when the drive was filled to 85% of its capacity.
