Average Bench: 23.2% - 162nd / 614

Based on 1,900 user benchmarks.  Device: VID 0781 PID 5581 Models: SanDisk SanDisk Ultra, SanDisk Ultra

Sandisk had phenomenal success with the Sandisk Extreme which I reviewed nearly two years ago. The Extreme is still one of the best flash drives available. I had high hopes for the Ultra despite its marginally more budget orientation. Unfortunately the 16GB Ultra turned out to be a disappointment. With sequential read/write speeds of just 75/9 Mbps the Ultra lies in the bottom 25% of 16GB USB 3.0 flash drives. Small file (4K) read/write speeds clocked in at 8.35/0.08 MBps which is also in the bottom 25%. On the bright side the Ultra USB 3.0 isn't overpriced so it does represents reasonable value for money but I would happily spend a little more and get the record breaking 16GB Sandisk Extreme [Feb '14 USBFlashPro]

I feel cheated. There's only 58.9 GB showing. Surely in laws relating to Sales Description you should get 64Gb or slightler over. Can you legally advertise something at more than it is?

Berbat! kendiliğinden yazma korumasına geçti ve çıkmıyor, biçimlendirilemiyor, sadece okunabiliyor. 16 GB'ın sadece 9-10 GB'ını doldurduktan sonra kilit! Daha önce de 2 adet MP3 player'de bu sorunu yaşamıştım, ikisi de çöp oldu bu da çöp oluyor :(—Apr '15
