"5 out of 5 eggsGreat for cameras, not for phones.
Pros: First, I have to say I am coming back to write a review because of Wintec's support! I've been emailing them back and forth, and today, 2 days after my last email, they called me out of the blue to get more details - and to pass me straight to the tech. Impressive.
(back on topic) After reading the other reviews here, I put this card through the ringer from day one for about a solid week. Using
www.iozone.org, I really loaded it up to beat on it for 2 hours at a time.
It passed any and all tests, hands down.
Rated as a Class 10 for 10 MB/s substained write speeds, I averaged ~18 MB/s with this card, sometimes peaking to 24 MB/s. PASS
Also, read was much higher than expected.
Seek time, not so much (see cons).
Cons: Windows Phone 7 has the highest requirements in the industry for microSDHC cards. Specifically, it seems cards with a random seek time of 8 ms or faster is about the only cards that works in Windows Phone 7 (aka WP7).
This is not one of those cards. And you'll be hard pressed to find a microSDHC card that advertises as such, as they are pretty much a shoot in the barrel.
This card measured a very low 18 ms on random seek time. When installing this card in my WP7 device, as expected, random reboots happened and applications crashed, as well as sever delays in launching applications.
Sticking in the stock Sandisk Class 4 card worked fine. I ended up purchasing a Sandisk 32 GB Class 2 card and and it measured 7 ms, with a WRITE that matched the OEM Class 4 card of 6.8 MB/s. That card works perfectly in my WP7. This Wintect card, did not.
This card is not suited for mobile phones because mobile phones require near-instant lookups to random data.
Other Thoughts: Buy this card for cameras that need very fast write speeds. It will exceed your expectations (or at least any card you own).
Do NOT buy this card for your mobile phone (Android, WP7, WinMo, etc)."
will work great in cameras, ok in tablets and maybe not so well in smartphones
