64GB USB Flash Drives External Data Storage Slim Thumb Mini Nano Micro Waterproof

Buono per qualità prezzo

Die Sticks sind die kleinsten mir bekannten. Lassen sich super ins Münzfach schmeissen ohne aufzutragen. Habe immer einen mit. Habe Ventoy darauf installiert und diverse Tools und iso Installationsimages. Die Sticks sind natürlich lahm. Zirka im Bereich 5-15MB/sec. Aber es sind keine Fälschungen. Habe schon 2x32GB und einmal 1x64GB und alle sind fehlerfrei und bieten volle Kapazität. Für meinen Einsatzzweck ideal.

Es muy pequeña, pasa desapercivida. Dejó de funcionar al mes, justo después de terminarse la ventana para devolución.

I wanted this for a wallet-sized flash drive. It works fine for what it is, and is authentic and functional, if slow flash (~3MB/s write ~25-30MB/s read). I think this is about as well as one can do if you just want to be carrying a flash chip+minimal USB contacts around. This device enumerates as VID 346D / PID 5678 "USB Disk 2.0" with a generic vendor name field. Write speeds are typical of a device with a small SLC cache and slower underlying MLC storage (~3MB/s overall including occasional bursts to USB 2.0 speeds of 20-25MB/s and slowdowns to ~1MB/s). Read speeds are ~USB2 (28.6MB/s for a full-drive read). The drive is ~of the stated capacity with typical loss to overhead (58.59GiB=61.44GB, received as EXFAT and formatted as NTFS here). Tests with F3probe/F3write/F3read indicate it's all usable. Build quality seems fine for what it is - it's a small chip-on-board type device with the expected level of thermal solution (i.e., virtually none - there is no room for a heatsink given the size). Given the write speeds it doesn't heat up appreciably during operation. It's very slow flash relative to modern devices, but anything USB3+ would probably just throttle anyway in this application. I would prefer a name-brand device but I think this is probably the realistic limit for this type of minimal device and it probably can't be done much better.
