Transcend 400X - speed confussions...???

2 unopened packs... the slower has a sticker under the shrinkwrap with the slower speeds...

still plenty of speeds....

their website says
- Data transfer rate: Read_90MB/sec (Max)*
Write_60MB/sec (Max)*


and then lower down on the site, it also says:
Transfer Speed:
Read 60 MByte/s, Write 30 MByte/s (8~16GB);
Read 90 MByte/s, Write 60 MByte/s (32~64GB)

1 speed rating, various meaning depending on size...

If you notice, the first spec lists (MAX). The other 2 listings break it down by different sized cards. I see nothing too deceptive but speed varying with size is not uncommon.

Well, yes, speed can vary with card size, but usually it's when you start using the last part of a large card that things slow down. What Transcend's selling is a 200x (write speed)/400x(read speed) card in the sub-16GB size and a 400x/600x if you get over 16 GB capacity cards. So either they're misrepresenting their smaller cards (based on write speed) or they're underplaying their bigger cards' performance (if you go by read speed). At the very least they're confusing their clientele.

Note that both of the pictured cards say 400x, and both are 16GB, yet one claims different r/w speeds than the other. Same capacity, same x rating, different claimed speeds. There is a clear discrepancy here. Maybe early units has a packaging typo. Maybe one's a counterfeit.

They probably both meet the 400x spec. Have to find the spec, first, to know.

x is the speed of first-gen CD-ROM's, roughly 150KB/s, so 400x would be 60000 KB/s.

Weird... lol Both are legit?
