The number that matters here is 150 megabytes per second — SanDisk's read rating for this drive — because it is the difference between a folder of photos copying while you read one email and copying while you make lunch. It is USB 3.0, it holds 128GB, and it costs less than the other high-capacity single drive in this guide. That combination is why it is our default recommendation.
In hand it is the nicest of the single drives here: a slim metal casing, almost nothing in weight, and an exposed plug with no cap to lose — which also means pocket lint finds its way in. We keep it in a small zip pocket rather than loose in a bag for exactly that reason. SanDisk's software adds password protection with 128-bit AES encryption, more than most drives at this level bother with.
What we do not do is treat any flash drive as the only copy of anything. A failed stick takes its files with it, and the metal shell here runs warm during a long write, which is normal for the category and no reason to worry. Two copies — one drive, one cloud folder — is the habit worth building around a drive you will actually carry.
Pros
- Reads up to 150 MB/s over USB 3.0
- 128GB in a slim metal body
- Password protection built into the software
- Cheaper than the other high-capacity single drive here
Cons
- Metal casing gets warm during long transfers
Our default pick for most people: 150 MB/s reads, 128GB, and a slim metal body that survives a bag, for less than the other high-capacity single drive here.
