Hacking Taiwan-made Kingston cards

[4saken]

Yes, thats true. Japanese kingstons are no longer in production, so you'd only expect to find them in small stores/small online stores.

The Japanese Kingstons were Toshiba cards anyway.
So if you want one then go for a Toshiba or one of the other brands that are the same card ( Viking and Dane-Elec are two that i know of that are the same Toshiba card).

There are not many micro SD manufacturers so a lot are coming out of the same factory badged for different brands. Though i suppose the more popular the format gets , the more facories will make it.

I wonder if the Taiwan Kingston cards are coming out of the same factory that makes the Sandisc cards ? !!!

I just tested my two Kingston cards using the SD adapter and my laptop's SD slot.

Taiwan 1 GB: 4.3 MB/s write, 3 MB/s read
Japan 512 MB: 4.5 MB/s write, 3 MB/s read

I have no idea why writing is faster than reading on them. The results for both seem pretty slow to me. Maybe the adapter is limiting them or my laptop's SD slot sucks.

The read should definitely be faster. What did you use to test?

Don't lower capacities usually yield faster results? If so, that test is also accurate.

If not, continue

I used ATTO.

The number I reported it from the 1 MB chunk read/write. I compared its read speed result with HDTach's and they were almost exactly the same, so I used ATTO to get the write speed since I don't have the paid version of HDTach that has writing tests.

I'm going to try a regular SD card now to see if my laptop's SD slot is a limiting factor since those results seem odd to me.

Update:
I just tested my 2 GB Kingston SD (Japan) card and got very similar results to the microSD cards, so I'm assuming my laptop's SD slot is the limiting factor.

I have a 1 GB Kingston microSD that says it was made in Taiwan (back of microSD) and i got a write speed of 4.46 MB/sec and a read speed of 9.95 MB/sec. Total length of transfer was 4 MB

 

[lenselijer]

read speed is the same, but you also need to write down the ms of the test in hdtach.

japan= 0.6ms
taiwan= 1.7ms

I implore you guys to check your Kingston's for warranty:

I bought mine on the cheap from a local store, but a competing store was selling imports not covered under Kingston.

Hmmph, mine is apparently Made In Japan.

Random Access: 0.9ms.

Average Read: 4.5 mb/s.

Ouch. Time to get a better card reader.

Hey people! Post your MicroSD info in my info thread so we can get database going!

Where is this thread? I've got a couple of different microSDs which I can test
