Expert reviews and ratings 80 The X9 Pro is one of the fastest SSDs around, and its diminutive size combined with rugged design makes it a great choice to use on the road. The 2TB and 4TB models are a better value than their immediate rivals, and you get transfers going up to 1,050MB/s. The lack of password protection is irksome, but if you don't need the feature, there are considerable savings to be had. By AndroidCentral on July 09, 2024 90 If you want elegant, fast and supremely compatible portable storage, Crucial's X9 Pro portable SSD delivers all. By TweakTown on December 11, 2023 80 Although we could hit the advertised maximum Sequential speeds with our testing, Crucial's X9 Pro is still a quick, very compact external SSD with the added bonus of hardware encryption and password protection. By KitGuru on October 24, 2023 90 The Crucial X9 Pro is a tiny, near-perfect external SSD with a sturdy, ruggedized frame, hardware-based encryption, a long warranty, and up to 4TB of capacity. By PCMag on September 14, 2023 90 If you are looking for a very fast, compact, and durable external drive, the Crucial X9 Pro and Crucial X10 Pro are excellent choices. They are attractively priced, and I found no faults with their design or use. By GearDiary on August 31, 2023 90 Marrying good looks, great performance, and affordability, the X9 Pro is one of the top 10Gbps USB SSDs on the market. By PCWorld on August 22, 2023 88 Micron's latest Crucial X9 Pro is an easy recommendation. It has everything you'd want from a portable SSD, including fast performance, a compact and rugged design, built-in encryption, and lots of storage space. Additionally, its pricing is reasonable. By Dong Knows Tech on August 07, 2023 80 For US customers, the aggressive pricing of the X9 Pro and its extra features make it a no-brainer. But for those in the EU or the UK, the older X8 and X6 remain a much better deal if you dont need encryption. Those that are looking for something quicker should consider the X10 Pro instead. By TechAdvisor on August 04, 2023 Both the Crucial X9 Pro and the X10 Pro share the same housing and shape except for their colors so it isnt a surprise that I have a lot of the same aesthetic-focused things on both pros and cons lists. The new design that Crucial came up with is surprisingly compact, especially compared to their X8. By LanOC on August 30, 2023 The Crucial X9 Pro has class-leading performance specifications, and the claimed numbers are backed up by our evaluation. There are certain scenarios where true top-tier SSD performance (such as high IOPS for random access scenarios) may be needed across a wide variety of use-cases. For such requirements, bridge-based PSSDs with a DRAM-equipped internal drive can perform better even within the 1 GBps-class interface limitations. By Nutesla on August 19, 2023Load More Reviews
