Rank #1 in Best 32GB USB Flash Drive 2026: 8 Ranked, Read vs Write
SanDisk Ultra 32GB USB 3.0 Flash Drive (Black)
Price and rating as shown on Amazon when we collected them. Both change.
The SanDisk Ultra 32 GB is the drive at number one in this guide. It is also the most reviewed product in the list by a wide margin: 210,354 ratings on the Amazon listing, averaging 4.6 out of 5, and 77 of the 100 ratings in the breakdown sit at five stars. It costs £14.79.
The number worth reading twice is the one in the title. SanDisk prints "Up to 130 MB/s Read" on the product name, then the specification table further down the same page lists Read Speed as 100 Megabytes Per Second — a 30% gap between the headline figure and the drive's own data sheet, with nothing on the listing to explain it. Write speed does appear in the spec table, at 80 MB/s, and the title does not mention it at all: the same page therefore offers three different speeds for one product. Everything below is taken from the Amazon listing for this drive — title, bullets, specification table and customer reviews — and not from any testing we have carried out.

Questions people ask
Why does the listing say 130 MB/s when the specification table says 100 MB/s?
The product title for the SanDisk Ultra says "Up to 130 MB/s Read". The specification table on the same Amazon listing gives Read Speed as 100 Megabytes Per Second. Both figures appear on the same page and the listing does not explain the difference, so treat 130 MB/s as the headline claim and 100 MB/s as the figure SanDisk puts in the data sheet.
Does the SanDisk Ultra 32 GB state a write speed?
Yes. The specification table lists Write Speed as 80. The product title does not mention write speed at all, and the listing gives no unit alongside that 80, so it cannot be checked against the 100 MB/s read figure on the same table.
What connection does the SanDisk Ultra 32 GB use?
The listing describes it as USB 3.0 enabled and USB 2.0 compatible, up to 10x faster than standard USB 2.0. The specification table lists Hardware Interface as USB 3.0, while a separate field, Hardware Connectivity Technology, is listed as USB 3.0 Micro B.
Can I protect files on the SanDisk Ultra 32 GB?
Yes — the listing states it password-protects and encrypts private files with SanDisk SecureAccess software.
What capacities is the SanDisk Ultra sold in?
The listing states 16 GB, 32 GB, 64 GB, 128 GB and 256 GB capacities. This page covers the 32 GB version.
How long does a full-length movie take to transfer?
The listing claims a full-length movie transfers in less than 40 seconds. It does not say which capacity of file or which direction of transfer that refers to.
