Crucial X9 Pro 1 TB: what it offers
Crucial X9 Pro 1 TB
Reads and writes up to 1050 MB/s over USB 3.2 Gen 2, has IP55 certification (resistant to splashes and dust), and ships with an included USB-C cable plus a USB-A adapter. Its anodized aluminum body with a rubber base protects it from everyday bumps. According to user reviews it is reliable and silent, and the activity LED helps you know when a transfer is in progress.
Pros
- Symmetric read and write speeds up to 1050 MB/s
- IP55 certification: resists splashes and dust
- Compact aluminum body (65 × 50 mm) with integrated USB-C cable
- Compatible with PC, Mac, PlayStation, and Xbox
- 5-year warranty
Cons
- No removable rubber sleeve (the Kingston XS2000 includes one)
- Hardware encryption requires manual activation in Windows or macOS
Speed and practical use
The X9 Pro uses USB 3.2 Gen 2 (10 Gbps), which in practice reaches about 1050 MB/s for both read and write. Copying 100 GB takes roughly 1 minute and 40 seconds, compared with 3-4 minutes on more basic 500 MB/s models.
The design is understated: an aluminum body without frills, an indicator LED, and a small loop to hang it from a carabiner or keychain. It weighs 47 grams and is only slightly larger than a credit card, though noticeably thicker.
For frequent transfers of large files (RAW photography, 4K video, project backups), the jump from a 5400 RPM portable hard drive to any SSD in this generation is far more noticeable than the jump between mid-range and high-end SSDs.
The faster alternative: Kingston XS2000 1 TB
Kingston XS2000 1 TB
The XS2000 uses USB 3.2 Gen 2×2 (20 Gbps) and reaches up to 2000 MB/s read and write, double the Crucial. It comes with a removable rubber sleeve and IP55 as well. The trade-off: to use all that speed your computer needs a USB 3.2 Gen 2×2 port, which is less common than standard Gen 2. On a normal Gen 2 port, the XS2000 performs the same as the X9 Pro.
Pros
- Up to 2000 MB/s with a compatible USB 3.2 Gen 2×2 port
- Removable rubber sleeve included for extra protection
- IP55 same as the Crucial
- Generally lower price than the X9 Pro
Cons
- Requires a Gen 2×2 port for maximum speed; on Gen 2 it performs the same as the X9 Pro
- 3-year warranty vs 5 years on the Crucial
What to buy
The Crucial X9 Pro is the strongest option for most people: its 1050 MB/s covers any typical task, the 5-year warranty adds peace of mind, and the aluminum body is very compact. If your laptop or PC has a USB 3.2 Gen 2×2 port and you will frequently transfer very large files, the Kingston XS2000 unlocks double the speed at a price that is usually somewhat lower.
Frequently asked questions
Does the Crucial X9 Pro work with PlayStation and Xbox?
Yes, it is certified as compatible with PlayStation 4, PlayStation 5, and Xbox Series X/S for external game storage. It also works with Android, though real-world speed depends on the phone's port.
What is the difference between USB 3.2 Gen 2 and Gen 2×2?
Gen 2 offers up to 10 Gbps and Gen 2×2 up to 20 Gbps of theoretical bandwidth. In practice, Gen 2 reaches about 1050 MB/s and Gen 2×2 can exceed 2000 MB/s. Most current laptops include Gen 2, but very few have Gen 2×2.
Does hardware encryption work on Mac?
Yes. The X9 Pro is compatible with FileVault on macOS and BitLocker on Windows. Encryption is not active by default: you need to enable it from the corresponding operating system utility.
Is it worth paying more for the 2 TB version?
If you expect to exceed 80% of the capacity, such as when backing up a laptop with lots of content or extensive video projects, the 2 TB version is better value than buying two 1 TB units.
