Capacity and Interface
4TB is the capacity that makes the X10 Pro stand out — enough room for a very large active project library, a complete game library and substantial archives in a single portable drive. The interface is USB 3.2 Gen 2×2, the fastest USB-C tier widely available outside of USB4 and Thunderbolt. On a Gen 2×2 host the X10 Pro delivers up to 2,100 MB/s read and 2,000 MB/s write. As with all Gen 2×2 drives, Macs and consoles cap at Gen 2 and the X10 Pro runs at about 1,050 MB/s on those hosts. For a comparison of USB standards, see our USB 3.2 vs USB4 explained guide.
Speed and Real-World Performance
The X10 Pro is rated at the same speed as the X10 — up to 2,100 MB/s read and 2,000 MB/s write — but the larger capacity and higher-grade NAND give it a real advantage in sustained writes. Moving very large project archives, multi-hundred-gigabyte game backups or large camera offloads is markedly faster than on a Gen 2 drive, often half the time of a SanDisk Extreme or Samsung T7. The aluminium chassis acts as a passive heatsink, which helps keep sustained performance up during long copies. On Mac and console it falls back to Gen 2 speeds and is no faster than the X9.
The 4TB capacity also delivers a quieter benefit: more NAND chips in parallel give more channels for the controller to write across simultaneously, which is part of why higher-capacity SSDs typically sustain their full speed longer than lower-capacity models in the same line. For very long camera-card offloads or full-project backups, the 4TB X10 Pro holds rated speed end-to-end where smaller drives might drop into post-SLC-cache direct-to-TLC writes.
Durability, Form Factor and Portability
The X10 Pro is built more premium than the X9 and X10. The chassis is a forged aluminium body that doubles as a heatsink, with a textured-grip insert. Crucial rates it for 2 m drop protection. It is not IP-rated for dust or water, so for fieldwork an IP-rated alternative is a better fit. It remains genuinely pocketable despite the 4TB capacity. For ruggedised alternatives at similar speeds, see our best rugged portable SSDs guide.
Compatibility: PC, Mac, Console, Mobile
The X10 Pro is fully backward-compatible with Gen 2 and slower USB hosts, and on Gen 2×2 PC hosts it runs at full speed. On Mac, PS5 and Xbox Series X|S it caps at Gen 2 speeds. On PS5 the X10 Pro is excellent as PS5 cold storage — 4TB is enough for a very large PS5 library — and plays PS4 games directly. On Xbox Series X|S the drive plays Xbox One games and stores Series X|S games. The hardware AES 256-bit encryption is a plus for users with sensitive project data. For console-specific advice, see our best PS5 expansion SSD guide and best Xbox Series X|S storage guide guides.
For working professionals carrying client data, the AES 256-bit hardware encryption is set up through Crucial’s Storage Executive software on Windows. Once configured, the encryption operates transparently — the drive prompts for the password on every plug-in. The hardware nature of the encryption is the key detail: there is no host-CPU overhead, no speed penalty, and the encryption holds even if the drive is removed from its host and connected to another machine. That is meaningfully better protection than relying on the host OS’s file-level encryption alone.
Who Is the Crucial X10 Pro 4TB For?
The X10 Pro 4TB is for the buyer who needs both serious capacity and Gen 2×2 speed in a portable. PC video editors with large 4K or 8K project libraries, content creators with deep media archives, gamers with huge multi-platform libraries, and professionals who back up many machines onto one drive will all benefit. The 4TB capacity is the key differentiator — most rivals top out at 2TB. It is less ideal for buyers who do not need 4TB (the cheaper 2TB X10 is the right step down) and for Mac and console users who will not see the full speed. The X10 Pro is also a strong choice for users who want to consolidate from multiple smaller portable drives into a single high-capacity drive — fewer cables, fewer items to lose, and a single point of backup management.
Pros and Cons
Pros: 4TB flagship capacity in a pocketable drive; up to 2,100 MB/s read and 2,000 MB/s write on Gen 2×2; aluminium chassis aids cooling; hardware AES 256-bit encryption; 2 m drop protection.
Cons: Premium price; full speed only on Gen 2×2 hosts; falls back to Gen 2 speeds on Mac, PS5 and Xbox; not IP-rated for dust or water.
Is the Crucial X10 Pro 4TB Worth It?
At around $507 the Crucial X10 Pro 4TB is a strong choice for the buyer who genuinely needs both 4TB of portable storage and Gen 2×2 speeds in a single drive. The 2TB X10 covers the speed-focused buyer at a lower price. For everyday users, the Gen 2 X9 is the sensible default. For PC creators and professionals at the demanding end of the portable-SSD market, the X10 Pro 4TB earns its place. For more flagship internal NVMe options, see our best internal NVMe SSDs for gaming guide. The combination of aluminium chassis, hardware encryption and Crucial’s warranty also makes the X10 Pro a more dependable long-term tool than many similarly priced rivals.
Frequently Asked Questions
Why choose the 4TB X10 Pro over the 2TB X10?
Mainly capacity. Both drives use the same Gen 2×2 interface and have similar rated speeds — the X10 Pro adds 4TB capacity, an aluminium chassis and AES 256-bit hardware encryption.
Is the X10 Pro fast enough for 8K video editing?
On a Gen 2×2 PC host, yes. Up to 2,100 MB/s read and 2,000 MB/s write comfortably supports 8K timelines off the drive. On Mac and consoles it falls back to Gen 2 speeds.
Does the X10 Pro have hardware encryption?
Yes. It supports hardware AES 256-bit encryption managed through Crucial’s Storage Executive software.
Is the X10 Pro a good PS5 expansion option?
It is excellent as PS5 cold storage at 4TB and plays PS4 games directly. PS5 games can be kept on it but only run from the console’s internal SSD or a Sony-approved internal M.2 NVMe expansion drive.
