Transcend 32 GB microSDHC Flash Memory Card TS32GUSDHC4E [Amazon Frustration-Free Packaging]

(This is the original review - please read all the way to the bottom for an update)

Bought this micro SD card about 6 months for my smartphone. Stopped working all of a sudden. Tried it on my laptop and was not even recognized. Fortunately had all original packaing so very easily went to Transcend's website to get an RMA form. Shipped the product with the form, a few days later I get a package back. Well: they sent me the memory back with a little sticker pointing to a MICRO SCRATCH ON THE PLASTIC, BARELY VISIBLE WITH THE NAKED EYE. They sent a form letter with a check mark next to "physical damage to product" and a parapgraph quoting their warranty. I couldn't believe it. I was not even awre there was a superficial scratch evidnetly from normal wear and tear until they sent this thing back to me. I literally had to get my wife's reading glasses to find this. Then I decided to take a picture of it with a MACRO lense so I can show everyone here what it is but can't... Read more

For price, warranty, speed, and dependability, look no further. This is the best of the bunch. To be fair, it is not perfect. There are pros and cons.
.
PROS
1. The unit comes with an SD adapter. As a result, it is usable for many electronic devices.
2. The speed is fast for a Class 4.
.
The write speed range is between 2.8-5.3 mb/s. Most of the write activity is at 4.0 mb/s.
.
The read/data transfer rate is between 13 and 25 mb/s. Most of the transfer activity concentrates at 19 mb/s.
.
I use this storage device in my Sansa MP3 Player. I can not tell the difference in speed between the built-in 8 gb. internal memory or the Transcend 32 gb. In fact, I prefer the recordings on the latter. The music sounds better.
.
3. It is the only product with a lifetime limited warranty. So, the material and construction have to be high quality. . . . Transcend is not stupid. Too many defects and short life make the product unprofitable to... Read more

I bought this Transcend 32GB MicroSD card for use in my 7" Galaxy Tab. It's a class 4 speed, which means that it has to have a read/write speed that is at least 4MB/s sustained. I clocked mine at around 4.5MB/s to 5MB/s which is consistent with their claims. It's been working well in my Galaxy Tab and I really can't complain. I've had great luck with Transcend brand memory cards in the past. They are cheap, reliable, and high quality cards. I don't think I've ever had one fail on me yet. I like that this card comes with an included adapter that lets you use this as an SDHC card too. This means that you can use it in Micro-SD and regular SDHC devices.

Here is some more information about SDHC cards and speed classes. This excerpt is taken from my own review of the 8GB Transcend SDHC card.
