What Buyers Say
While generally praised for its speed and compact, durable design, some users have reported concerning issues with drive corruption after less than a year of use. The inclusion of hardware encryption and broad device compatibility are frequently highlighted as positives.
“Man, this thing was super fast for my video edits, but then it just died on me after less than a year, giving me I/O errors. Seriously bummed out, thought Crucial was better than this.”

Frequently Asked Questions
Does it work with iPhone?
Yes, it is specifically mentioned as 'iPhone 15 ready' for saving pro resolution photos.
Is it bus-powered?
Yes, portable SSDs like this are typically bus-powered, meaning they draw power directly from the connected device via the USB cable.
What kind of cable does it come with?
It includes a USB-C to USB-C cable. A USB-C to USB-A adapter is available separately or in a bundle.
Does it get hot during use?
While not explicitly mentioned as a common complaint in the provided snippets, portable SSDs can generate heat during prolonged, heavy transfers.
Is the password protection hardware or software based?
It features 256-bit AES hardware encryption for data security.
What is the actual real-world speed?
Crucial rates it for up to 1050MB/s sequential read and write, measured on a high-performance desktop. Actual performance can vary based on your system and workload.
Buying Guide
When picking a portable SSD, you need to think about how fast you need to move files and how tough it needs to be. Don't just look at the biggest number for speed; make sure your computer actually has a port that can handle it, like USB 3.2 Gen 2 for 10Gbps. If you're taking it outside, check for water and dust resistance ratings like IP55.
Read/Write Speed (e.g., 1050MB/s)
This is how fast files move to and from the drive. Think of it like a highway: a higher number means more lanes and a higher speed limit, so your large video files or photo libraries transfer much quicker than on a slower drive.
IP55 Water and Dust Resistance
This rating tells you how well the drive can handle splashes and dust. IP55 means it's protected against dust ingress and low-pressure water jets from any direction, making it suitable for outdoor use but not for submersion.
256-bit AES Hardware Encryption
This is like a built-in, super-strong lock for your data. If someone gets their hands on your drive, they can't access your files without the password, because the encryption is handled by the drive itself, not just software on your computer.
USB-C Interface (USB 3.2 Gen 2)
This is the type of connection the drive uses. USB-C is reversible and common on newer devices, while USB 3.2 Gen 2 is the specific standard that allows for speeds up to 10Gbps (which translates to the 1050MB/s speed).
Alternatives
If you need even faster transfers for uncompressed 8K video editing, look for drives with USB 3.2 Gen 2x2 (20Gbps) or Thunderbolt 3/4 (40Gbps) interfaces, but be aware these require compatible ports on your computer.
