作者: anon893    時間: 2012-6-3 04:48


Sorry to hear.
Just remember this: modern C6 cards are NOTHING near the older ones some years ago in terms of speed performance
Back then C10 classification was not established yet, so C6 had the highest and best speed performance available
Those C6 cards, despite expensive, were a gem, and may have similar performance as that of a modern C10 card... maybe only a tad slower in write speed, but can still achieve 16-18MB/s write depending on brand (eg. Transcend C6 8GB)

So you still have that PQI C6 8G?
Can you do us some benchmarking results on that?

Something is not right...
How come Verb c10 card is below C10 write standard
Maybe your card reader is getting old
Anyway try another reader and connect reader directly to USB2 port (not hub), then try again

BTW your PQI card speed performance is similar to Toshiba MIJ white c6 2GB sold some years ago (~20r/16w)

作者: anon893    時間: 2012-6-11 05:33


Actually yschin is totally right
R19/W11 for a recent C10 card is only marginal performance, performance similar to Transcend C10 Ultimate

Just look at Toshiba, white C10 still MIJ and can still retain ~R23/W20 performance... that's what a C10 card should be

Yes please...
Try testing card under USB2 connection
Also try testing from another card reader

BTW whith motherboard are you using?  Which controller?
Try listing the conditions inside ATTO description

@thomasckau
This Transcend is no good, only R19/W11 meagre performance, even worse than C6 cards sold few years back (~R20/W18)
Pay a bit more for Toshiba white C10 for more assurance... (at least that's how I tell people)

作者: anon893    時間: 2012-6-14 05:43


Actually you have to identify the USB controller and motherboard model etc. first, then manually type them into the description box

Other testing conditions may also be included in the description
eg. Does the HP notebook have an internal card reader which you used to do the test?  Or did you attach a separate card reader (also which model)?

Looks like performance under USB2 is quite good and stable, but since you used a notebook for the benchmark, results may be slower I think
Try doing this benchmark test on a desktop PC if possible
