This article covers Crucial(クルーシャル) X10 外付け SSD 8TB USB3.2.

Overview

The Crucial X10 Portable SSD is a high-performance external drive from Micron's consumer brand, offering up to 8TB of storage in a compact, rugged form factor. With sequential read speeds reaching 2,100MB/s over USB 3.2 Gen 2×2, it's one of the fastest portable SSDs on the market. The drive features IP65 dust and water resistance, making it suitable for outdoor and field use. It connects via USB-C and works with Windows, Mac, Android, iPad, and even iPhone 15 series. The exclusive bundle includes a 3-month Mylio Photo+ subscription for photo management.

Compatibility Guide

The X10 uses a USB-C interface and supports USB 3.2 Gen 2×2 (20Gbps). It comes with a USB-C cable and is compatible with any device that has a USB-C port. Supported operating systems include Windows, macOS, Android, iPadOS, and Linux. It also works with game consoles like PS4, Xbox One, and PS5 (for storage only). For older PCs with only USB-A ports, a USB-C to USB-A adapter is required. To achieve the full 2,100MB/s read speed, the host device must support USB 3.2 Gen 2×2; most current laptops and desktops only support USB 3.2 Gen 2 (10Gbps), which will cap speeds at around 1,000MB/s.

Product Info

Released in 2025, the Crucial X10 Portable SSD sits at the high end of the portable storage market. It offers 8TB capacity in a pocket-sized enclosure, with read speeds up to 2,100MB/s. The drive is IP65 rated for dust and water resistance, and comes with a 5-year warranty through authorized resellers. The exclusive version includes a Mylio Photo+ subscription code. Market positioning is clearly for professionals and power users who need fast, large-capacity, and rugged external storage.

Best Use Cases

Creative Professionals & Photographers: The 8TB capacity can hold massive RAW photo libraries and 4K/8K video projects. Fast read speeds enable smooth editing directly from the drive. The bundled Mylio Photo+ trial helps organize media. However, write endurance (TBW) is not specified, so heavy daily write workloads may be a concern. Gamers: Expand your game library on PC, PS4, Xbox One, or use as cold storage for PS5 games. PC gamers will benefit from fast loading times. Note that PS5 games cannot be played directly from USB storage. Field Workers & Outdoor Enthusiasts: IP65 rating protects against dust and water splashes, making it ideal for on-site data collection, photography in harsh environments, or carrying sensitive data in rugged conditions. Backup Solution: Use with Time Machine or Windows Backup for large-scale backups. The 8TB capacity can handle multiple system backups. Not recommended for always-on NAS use.

Things to Consider

The X10 is read-speed optimized; write speeds are not officially published, and may be significantly lower than read speeds. The lack of a published TBW rating makes it difficult to assess long-term endurance for write-intensive tasks. To achieve maximum speed, your host device must support USB 3.2 Gen 2×2, which is still uncommon on many laptops and desktops. At around ¥158,000 for the 8TB model, it's a premium investment compared to HDDs or lower-capacity SSDs. If you don't need 8TB, consider the 4TB or 2TB variants for better value. ## FAQ
Q: Can I use this directly with an iPhone 15 Pro? A: Yes, it works with iPhone 15 series via USB-C. You can access files through the Files app for photo and video backup. However, continuous heavy writes may require external power due to iPhone's limited power output. Q: Can I play PS5 games directly from this drive? A: No, PS5 games can only be stored on USB external drives, not played directly. You must copy them to the internal SSD to play. PS4 games can be played directly from the external drive. Q: What is the write speed? A: Crucial has not published official write speed figures. Based on typical performance of similar drives, expect write speeds around half the read speed, but actual performance varies by workload and host hardware. Check independent reviews for real-world numbers.
