Are these any good? I want to buy 150x (class 6) cards and these are the cheapest (and only available above 2gb) on Amazon, but prior to seeing them there I haven't heard of the brand before. Are they reputable or should I pay extra for a brand like sandisk?

I have two Transcend 4GB 150x SD cards. They work extremely well, pics get stored in record time.

My cards are regular SD cards, not SDHC. The class designation applies to SDHC cards only. So you must be looking at another type than those which I have.

Ah ok. But I'm not sure if the impression I have is correct... doesn't the "SDHC" format simply allow cards to go up to 32gb in size? Or does it make a difference to the performance of the card itself?

Amazon have Transcend 150x SD and class 6 SDHC with only a few £ difference in price, so I'm slightly confused as to whether there is an advantage to buying either one?

class 6 SDHC is not as fast as 150x in and SD card.

SDHC classes:
Class 2 = 2 MB/s
Class 4 = 4 MB/s
Class 6 = 6 MB/s

With regular SD, it is something times x: 20x, 40x, 150x, etc. That x is 150 kilobytes per second, the same as a single spin CD-ROM drive. So 150x should be about 22 MB per second.

From my understanding, SD and SDHC are different technologies. I can only comment good things about my SD 150X Transcend. My local photo center only lists SD on the kiosk, so thats why I went with only the SD card.

Only buy memory cards from reputable chain stores.

Just a note that the Transcend 4gb card I bought was faulty and corrupted photos after the first few shots stored on the card. I returned it and went with a Sandisk Ultra II and have had no problems since.

I have 2 133x 1GB Transcend cards and 2 150x 2GB cards. All 4 work have flawlessly so far.

Thanks for the comments. I still don't understand though if there is a difference between SD and SDHC in terms of performance. I know SD uses FAT16 file system and SDHC uses FAT32, but does anyone have any idea what this means in real money, except the allowance to go up to 32gb in capacity?

I don't see how Class 6 SDHC could be that much slower than 150x SD when they are such a similar price. I'm thinking I might just buy the fastest 2gb card in every brand I can so if one breaks I won't loose confidence in the others!

Also, can anyone tell me what speed the Ultra II and Extreme III sandisk cards are? I guessed that Extreme III were 150x, which is what I want. But I might be wrong.

Thanks

My Transcend 4GB 150X shows up FAT32 on my computer. Costco has the best price on them (in Canada).

[Kaimarx]

Extreme III's are rated at 20 mb/sec (about 150x) so going on the above calculation that would mean the ultra II's are around 133x.

Although i dont own one personally almost everyone i know who takes digital photos swear by the transcend cards. Might have to score me one too seeing as there alot cheaper than the Sandisks.

[silverbullet]

Sandisk Ultra II SD cards are 66x cards. Half the (theoretical) speed of the Extreme III.

I'm using a Transcend 2GB 150x SD card for nearly two years and I'm planing to buy another one.

[pixelpruner]

sweet thanks for all the comments. the only thing drawing me to paying the extra £5 ($10) for the sandisk cards is the data recovery software. Anyway, I'll buy without worrying about the transcends being dodgy cards and this whole SD/SDHC thing. Cheers.

se above for the answer. Add on that an SD reader will not read an SDHC card unless it is also an SDHC reader. SDHC is different technology than SD.

Not to mention that although there are 4GB SD cards, the SD standard only goes up to 2gb. what can read and write to them is hit or miss.

My personal take is buy multiple cheap 150x 2gb sd cards. THey work fast in all my card readers, my camera likes them, and if any one goes bad, it takes a smaller chunk of your pictures with it (especially in RAW).

Buying transcend 150x from a reputable vendor seems to be the way to go.

Nice, thanks for that summary raz-0. I have ordered multiple 2gb 150x sd cards. lets hope I now have enough to last me my holiday!
