Hello everyone on forums!
Few days ago, I bought:
- Extreme pro microsd card 8GB, Product Code SDSDQXP-008G-X46,
2. Extreme pro microsd card 16GB Product Code SDSDQXP-016G-X46 and
3. SanDisk 64GB Cruzer Extreme USB 3.0 Flash Pen Drive Product Code SDCZ80-064G-G46.
They are from more than decent UK retailer based on reviews, packaging was immaculate and I would say they are genuine Sandisk products. Even coupon code for some software was included which I haven’t checked, I would guess that false products neglect things like this. I do oppose advice seen on these forums to search for high priced Sandisk products, would that really be some warranty?!
Anyway, I’m here because all three are slower than stated. Some people on Amazon reviews claim that they achieved highest speed.
Microsd cards passed h2testw_1.4 test with speeds 64 MBps
USB stick passed h2testw_1.4 test with speeds 59 MBps
Large file copy in Windows 8.1 speeds: 55 MBps read, 75 MBps write, USB stick 55 MBps read& write. So its pretty far from 245 MBps advertised and microsd cards aren’t perfect either. On same USB 3.0 port 2.5" 5400 rpm HDD goes up to 80 MBps which is great.
So, they are some doubts and my subjective experience in using them on my tablet, smartphone and PC is unsatisfactory.
Please share some insights…
