SanDisk 64GB Ultra USB Flash Drive USB 3.0 sits on our memory cards & storage shelf, where the ranking comes from what buyers actually said rather than from what the box says. From the seller's own listing: 32 - 113 degrees F (0 - 45 degrees C). Storage temperature: 50 degrees - 158 degrees F (-10 degrees - 70 degrees C). Protects and encrypts private files with SanDisk SecureAccess software. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.6 out of 5 across 210,423 ratings. How that compares with the rest of the shelf is below.
The typical memory cards & storage product on our shelf scores 4.6 out of 5, measured across 50 rated products. This one comes in at 4.6. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.
That score rests on 210,423 ratings. The median for this shelf is 12,973. A score built on that many opinions is hard to shift and hard to game, which is why we weight review volume rather than ranking on stars alone.
On money, this sits in the bottom third of a shelf running from £6.99 to £185, with the midpoint around £21.84. Cheap with a middling rating is a fair trade if the specifics suit you, and it is the usual reason to pick something at this end of the shelf.
