Crucial P3 Plus 1TB
Score: 73/100Rankings
The Crucial P3 Plus 1TB is a budget-oriented PCIe 4.0 NVMe SSD that offers blazing sequential read speeds and a large pSLC cache for fast burst writes, delivering strong first-impression performance. Its DRAM-less design and limited random IOPS cause latency and throttling once the cache is depleted, making it less suitable for sustained heavy-write workloads. It is best for gamers and general users who want Gen4 speeds without a premium price.
The Fanxiang S101 1TB SATA SSD offers an affordable upgrade path for older laptops and desktops, delivering up to 550 MB/s read speeds with reliable TLC NAND. Its limitations include the SATA III bandwidth ceiling and lack of advanced features such as DRAM cache or hardware encryption. It is best suited for budget-conscious users needing a simple storage boost on legacy systems.

Professional reviewers consider the S101 a solid, low-cost option for users who need a simple SATA upgrade. While it delivers the expected speed gains over HDDs, its SATA III bandwidth and lack of premium features make it unsuitable for performance-critical workloads, and external use via USB shows markedly lower speeds.
Professional reviewers commend the P3 Plus for its impressive sequential throughput and aggressive pricing, especially the 64K write performance that outpaces many QLC competitors. However, they consistently point out its weak random IOPS, high latency, and the drawbacks of a DRAM-less architecture, which cause sustained write speeds to tumble once the cache is exhausted. Overall, they view it as a solid budget Gen4 option for bursty workloads but not a contender for performance-critical or heavy-write scenarios.
Everyday users love the noticeable speed boost in booting, app loading, and large file transfers, often describing the experience as "very snappy" and a "massive jump" from SATA or HDD setups. Recurring complaints focus on performance throttling after the cache fills, heat concerns without a heatsink, and disappointment with random small-file speed, especially for VDI or database-type tasks.
