Crucial P3 Plus 1TB
Score: 73/100Rankings

The SanDisk Extreme Portable SSD 1TB delivers high-performance NVMe speeds of up to 1,050 MB/s read and 1,000 MB/s write while offering IP65 water and dust resistance in a lightweight 52 g package. Its capacity is limited to 1 TB and it lacks the ultra-fast 2,000 MB/s class of newer models. Ideal for creators and mobile professionals needing fast, rugged portable storage.

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.

Professional reviewers commend the Extreme Portable SSD 1TB for its high sequential read speed, noting it delivers smoother playback when editing video files. They also appreciate its lightweight, bus-powered design and the inclusion of both USB-C and USB-A adapters, which together make it a solid choice for creators on the move.
Everyday users have limited publicly documented feedback, but the available comments emphasize appreciation for the drive's speed, portability, and cross-platform compatibility.

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.
“the speed of this SSD mainly when reading files will provide smoother playback”
