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.

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.

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.

アンドロイドスマホの記録媒体としては優秀

機能は全く問題ありません。が常にスマホのキーホルダーにつけているためか回転軸の止めがユルユルになってしまいます。対策は難しいと思いますがバージョンアップを期待します。

Handy and Versatile

This flash drive is a real Swiss Army knife! The dual option (USB-A and USB-C) is perfect for those like me who switch between different devices and environments. It’s super practical, compact, and very fast for transfers. A lifesaver for anyone needing versatility in their daily routine. No regrets with this purchase, and I strongly recommend it!

余計なモノがなく、容量と速度も妥当

キャップ式はキャップを無くすし、スライド式は段々引っかかりが甘くなる。その点、この回転式はベスト。しかも、厚みが最少でコンパクト。ただ、その分、本体が熱くなるとダイレクトにホットになって取り外しに注意が必要だ。容量辺りのコストや書き込み・読み出し速度も妥当だし、タイミングを変えて結局複数買ったり、他者に勧めている。ハードディスクほどの容量は要らず、常時使用もしない場合に最適。また、SSDは、速度は魅力だけれど長期の信頼性や、他者との共有を考えると、まだまだUSBメモリのニーズはある。ラベルが付けられないのと本体が熱くなるので、ストラップホールに何か付けて差別化するのがよさそう。

Not working

Working for about 2-3 minutes, after which it stops working and the stick is not available on Windows. Probably broken, this is why it's refurbished.

Works fine, delivery fast!

Very handy having both a usb and type c port. Has a short installation app for phones but great for that easy access when it has two ports to plug and play. Very compact! So small in fact that I have to clip it with a keychain so it doesn't disappear on me, but that's a compliment!
