SanDisk 64GB Ultra Dual Drive Go USB Type-C Flash Drive - SDDDC3-064G-G46

Q: I bought one 64gb and it has printed the same but it actually has 32gb when i looked into my windows system. why is it so?

Have you looked at how the flash drive is set up? There's an outside chance that it merely has 1 primary partition set up as 32gb and 'unallocated' space that is the other half of your storage. For this you'll need to look at the drive with Disk Management in Windows to see how partitions are configured.

Q: Is the usb-a connector backwards compatible with usb 2.0 ports?

Yes, it should be but without the same transfer speed as 3.0.

Q: How many pictures will the 256gb sandisk hold?

A 256 GB Flash Drive will hold roughly 150,000 pictures. Or, it will hold about 50,000 pictures and 35-40 hours of movies together. At least according to my math from investigating data about this.

SanDisk 64GB 3.2 USB-A USB-C Flash Drive (SDDDC3-064G-G46)

A fast and compact USB 3.2 flash drive.The plastic casing is an advantage for me, as it reduces the risk of short circuits.

使いやすいが紛失もしやすい

以前購入した128GBのメモリースティックが行方不明になってしまったので、改めて64GBの物を購入する事にした。ファイルの読み込みがスムーズで使いやすいものの、スティック本体が小さいので狭い所に落として気付かなくなる可能性がある。とにかく、その点は色々と気をつけたいところです。

記載通りの性能で欠点も特になく大満足

10年ぶりくらいにUSBメモリを買いました。自炊した漫画や動画を格納してiPhoneで開くのに、本体やクラウドストレージを大容量データで圧迫させたくなかったのが目的です。以前買ったときはシリコンパワーのUSB3.0 16GBで3000円くらいでしたが、今は1000円ちょっとでUSB3.1 64GBが買えるとはありがたいです。SanDisk製のフラッシュメモリなので信頼性も高そうです。iPhone 16ProにType-C側をぶっ刺して使ってますが、表記通り実測値でも読み150MB/s・書き100MB/s程度の速度が出てます。他のレビューにもあるとおり小さすぎて無くしそうですが、キーホルダー等に取り外しできるプラバックルで付けておくと良い感じです。Type-A側を使ってないのと落下等の衝撃はまだ未経験なので耐久性は不明です。総評としては非常に満足しています。あまりUSBメモリを買うことはないですが、今回も当たりの商品を購入できたと思います。

古いPCでも書き込み速い

みなさんがおっしゃる通りかなり高速な印象です古いPCでUSB2.0ですが手持ちのUSBメモリの数倍早い印象ですクリスタル何とかで測るとランダム書き込みが3MBぐらいでした手持ちのUSBだと0.07との表示でしたので驚きましたこれでUSB3.1とかUSB-Cとかだともっと高速なのでしょうかそれにしてもこれから使うのはこれ一択になりそうです

スマホケースとの干渉なし

USBメモリとしてはコンパクトで驚きました。type-Cの端子部分もスマホケースと干渉しないデザインとなっており非常に使いやすいです。まだ使用して間もないため、耐久性については不明です。クラウドがあまり好きではないのでスマホ、パソコン、このUSBメモリの3つに写真やデータを保存してバックアップをしております。
