Best Value & Lightest Weight
Crucial X9 Portable SSD
The Samsung T7 and Crucial X9 are both made by companies that manufacture their own NAND flash — Samsung and Micron respectively — which means neither is relying on a third party for the core component that determines drive performance and longevity. They reach near-identical sequential read speeds, but differ meaningfully on durability rating, write speed, design, and price. The Crucial X9 undercuts the T7 by $20–$30 on a 1TB drive; the T7 offers a stronger IP rating and hardware encryption. Here is the full breakdown.

Speed Performance
Sequential reads are identical at 1,050 MB/s on both drives when connected to a USB 3.2 Gen 2 port. Where the T7 has a meaningful advantage is sequential write: up to 1,000 MB/s vs the X9's ~900 MB/s. This 10% write advantage matters for workflows where you are pushing data onto the drive — backing up a camera card, writing a large video project, or cloning a system disk. For read-heavy workflows (reading footage, loading assets, transferring to a laptop) the drives are essentially identical.
Durability: IP65 vs IP55
This is an important distinction. The Samsung T7's IP65 rating means it is fully dust-tight (6) and protected against water jets from any direction (5). The Crucial X9's IP55 rating means it is partially dust-protected (5 — not fully sealed) and also water-jet protected from any direction (5). In practice, day-to-day use rarely exposes a drive to sustained dust or water jets, but if you work in genuinely dusty environments (construction, workshops, desert terrain) or wet conditions (marine, rain-heavy outdoor work), the T7's complete dust seal is a meaningful advantage.
Encryption: Hardware vs Software
The T7 uses hardware-level AES 256-bit encryption — the encryption chip is built into the controller and operates without software overhead. The X9 uses software AES 256-bit encryption that requires the Crucial Storage Executive software to enable. Hardware encryption is generally faster, more secure (the key never exists in system RAM), and works without drivers. For most users the difference is academic; for IT-managed environments handling sensitive data, hardware encryption is the professional standard.
Value per GB
The Crucial X9 saves approximately $20–$30 per 1TB drive compared to the Samsung T7. Over two or three drives (common for photographers and videographers who keep a drive per project or per client), this adds up to $60–$90 in savings. The X9 achieves this partly by using a plastic housing instead of metal and a simpler IP55 rating — cost-cutting that most users will never notice in daily use.
Pros & Cons

Frequently Asked Questions
Is the Crucial X9 as reliable as the Samsung T7?
Yes — Crucial (owned by Micron) manufactures its own NAND flash and has a strong track record in consumer and enterprise storage. The X9 uses 3D NAND from Micron's own fab. Both drives should deliver equivalent long-term reliability in normal use. Backing up data regardless of drive brand is always recommended.
What is the difference between IP55 and IP65 for everyday use?
For most people in most situations, both ratings provide adequate protection. IP55 means partial dust protection (can keep out dust at normal levels) and water jet protection. IP65 adds full dust-tight sealing. The real-world difference matters most in dry, dusty environments like workshops, construction sites, or desert locations where fine dust can infiltrate IP55-rated devices over time.
Can the Crucial X9 be used with a Mac without any special software?
Yes. The X9 works immediately on macOS without any software installation — just plug in and use. The encryption feature requires Crucial Storage Executive (Windows/Mac compatible). For basic file storage and transfer, no software is needed on either Windows or macOS.
Which drive is better for a photographer as a card offload drive on location?
The Samsung T7 is the better choice for location photography — faster write speeds (1,000 vs 900 MB/s) mean you offload card contents faster, and the IP65 rating handles the inevitable sand and rain exposure on outdoor shoots. The fingerprint scanner on the T7 Shield adds security for irreplaceable client images.
Do these drives work with tablets and phones?
Yes, via USB-C OTG. Both drives connect to Android tablets and phones with USB-C OTG support for file transfer. They also connect to iPad Pro and iPad Air models with USB-C ports. Speed depends on the device's USB controller — most modern flagship phones and iPad Pros support USB 3.x for fast transfers.
Is hardware encryption on the T7 actually meaningfully more secure than software encryption?
Hardware encryption is generally considered more secure because the encryption key is stored in the drive's controller — it never exists in system memory where it could be extracted by a software attack. Software encryption processes the key in RAM, creating a theoretical attack vector. For most personal use cases the risk difference is low; for enterprise security compliance (FIPS, GDPR, HIPAA data handling), hardware encryption is typically required or strongly preferred.
What happens if I lose my encrypted T7 or X9?
Without the password (or fingerprint on T7 Shield), the data on an encrypted drive is inaccessible. The drive can be wiped and reused, but the existing data cannot be recovered without the authentication credential. This is a feature, not a bug — it means a lost drive containing sensitive data cannot be accessed by whoever finds it.
Which drive handles 8K video editing better?
Both drives handle 4K ProRes and H.265 editing comfortably. For 8K RAW workflows (which can exceed 500 MB/s constant read), both drives approach their sequential read ceiling and may struggle with real-time playback of uncompressed 8K. In this scenario, Thunderbolt 3/4 NVMe solutions provide more headroom. For proxy-based 8K editing workflows both drives are fine.
