Differences first. Select a topic for its graphic, sources and conditions.
Decimal storage capacity: 1 TB = 1,000 GB. Formatting and system use reduce available space.
Check the connection before the capacity. M.2 NVMe modules and 2.5-inch SATA drives are not interchangeable. Check the host’s protocol, slot or bay, power connection and clearance. Rated speeds use different test systems; we do not turn them into a speed score or overall winner.
16 verified differences, most decision-relevant first. 7 are also drawn in Visual facts above. Missing information stays separate.
