Micro SD Card - clevertech74 - 2014-03-21
Hello
Does the iNew v3 support Micro SDHC Cards or just Micro SD ?
Thanks.
RE: Micro SD Card - linr76 - 2014-03-21
supports SDHC (4-32GB)
HC = high capacity
probably would even support XC, but the 128GB cards are still very expensive.
SD = 8MB -> 2GB
HC = 4GB -> 32GB
XC = 64GB - 2TB

Thanks a lot mate !
Very well explained

your welcome ;)
i am a camera nutter, so i have to now that stuff....
back in the days when the cameras had CF cards was real fun, so many different things to keep in mind...
btw, if you want a fairly fast card and its mainly not for taking video then a class 6 is more than enough.
if you are operating with lots of small files a class 4 actually is better (better random read/write speed, but slower when writing larger data)
so class 6 is usually a good compromise, as mostly you will have mp3s, pictures and such which usually are a few MB in size.
good cards are Samsung, Transcend, Sandisk, Kingston (in that order, but that is my personal preference ymmv)

Thanks mate, very good information !
Now i know the different options
Many Thanks for your help.

Massively helpful to have an expert in the house. Does a Class 10 have specific usage-optimizations / usage-limitations as you've described above for the class 4/6, or is it all-around superior at simply a higher cost?
RE: Micro SD Card - nikstar - 2014-03-21
Also 64gb cards are working on iNew.
RE: Micro SD Card - linr76 - 2014-03-21
ok so here is the deal with sd cards:
the class is MB/s sequential r/w
cards with high sequential r/w have low random speed.
usage "optimization":
if you plan on using the card for apps (app2sd or such) then its better to go for a class 4 as it has the highest random r/w
if you want to copy big data chunks fast (eg take a lot of video or work with high resolution pictures as in DSLR cameras) the class 10 is best.
class 6 is slower in seq. r/w than class 10, but faster in random r/w (but still slower than class 4 random r/w)
so you can see it really depends on what you will use it for.
thats why i said class 6 is a good compromise.
RE: Micro SD Card - WuddaWaste - 2014-03-22
As a data junkie, I want to hug the ever living heck out of this whole thread. Thanks so much, linr76!!!
Now I'm debating ditching my Class 10 and buying a Class 6. Engineering tradeoffs are so hard to decide on! Why can't money just solve all problems?
RE: Micro SD Card - linr76 - 2014-03-22
glad to be of help.
there was also a huge thread about this on x..d..a.. where people also posted their benchmarks for different cards, different classes and so on.
if you want to see what you would gain when changing to class 6 i would suggest taking a look around.
generally speaking, class 6 and 10 both share the technology that speeds up sequential r/w but slows down random.
whenever you want to read or write data, the area of the data will be initialized, which produces a small overhead for random access.
but for high volume data transfer this trick speads up the r/w operation drastically.
actually it was invented for the DSLRs, since with larger sensors and more MP the older style cards were not fast enough (if you shoot raw format you can end up with images 30-50MB large). Video is even worse, since for 1080p/30fps you need to store 30x 2MP pictures per second.
there are also cameras which can do 1080p/60fps....
for professional DSLRs still Compact Flash is in use as they are generally faster than SD.
Nikon also uses XQD cards, those work with PCI-e 3.0, with speeds up to 1000Mb/s (they are not cheap... lol)
