Crucial X10 Pro 4TB Portable SSD

Pros

• +4TB — the largest capacity here, one drive instead of juggling several smaller ones
• +Up to 2,100MB/s read and 2,000MB/s write on a 20Gbps host
• +IP55 dust-and-water resistance plus a drop rating in a compact aluminum body
• +Aluminum shell sheds heat well over long sustained writes, resisting throttling
• +Also sold in 1TB and 2TB if 4TB is more than the workflow needs

Cons

• −The 4TB model is the highest total outlay in this roundup
• −Full write speed needs a 20Gbps host
• −Overkill capacity for anyone who offloads and clears cards regularly
• −Costs more per terabyte than the standard X10 for the IP55 and write-spec gains
