Genuine Class 4 SanDisk 32 GB microSDHC card from Everything But Stromboli
By D. Harris
I purchased two of these memory cards from seller "Everything But Stromboli" via Amazon.com. Both were genuine SanDisk cards and appeared to be new as promised. Some sellers are selling fake SanDisk cards so be cautious to make sure that the seller you choose is not cheating you with a cheaper substitute.

I ran a thorough analysis on my cards and all 31,914,983,424 bytes of each card were "verified" with zero errors (it took slightly over 6 hours per card for this test!!!). The formatted capacity in a Motorola Droid X phone was 29.66 GB (which is normal for a 32 GB card---the formatted capacity is normally a little less than the unformatted capacity). Note: You should always format your card in your phone (NOT your computer) before you start using it. This is true even if your card came preformatted.

I tested the write speed of the cards and they were around 5.4 MB/s (megabytes per second) which exceeds the 4 MB/s minimum for a Class 4 card. SanDisk has a reputation for rating the speed of its cards conservatively and this is definitely the case here. By the way, I have a couple of "Class 2" SanDisk cards that are even faster than these Class 4 cards.

Further testing revealed that a Droid X (running Android 2.2.1) takes longer to mount a 32 GB card than a smaller card. Evidently the larger the capacity of the card, the longer it takes the phone to "prep" the card for mounting. This is probably because the FAT (file allocation table) is larger. I think this is normal and buyers should expect this from a larger card. The delay is noticeable when the phone is turned on and when the phone is connected to a computer via a USB cable in "Mass Storage" mode.

I also noticed that my computer seemed to sometimes have trouble mounting the card via USB cable while it was in the phone ("Mass Storage" mode). I think this may be a result of the Droid X taking a little longer to mount/unmount such a large card---perhaps the computer times out while waiting for the phone to unmount the card. A simple solution was to toggle the phone's USB mode to "Charge only" and then back to "Mass Storage" while still connected to the USB port of the computer. By the way, there was never any problem mounting the card when it was removed from the phone and connected directly to the computer via a microSDHC-to-USB adapter. However, I prefer NOT to remove a memory card from a phone unless it is necessary because they are fragile and easily damaged.

These are great memory cards and I'm very happy with my transaction with Everything But Stromboli on Amazon.com.

Kind regards, D.Harris

SanDisk 32GB MicroSDHC High Speed Class 4 Card with MicroSD to SD Adapter Sold by: Everything But Stromboli Ltd.
By Chris Midgley
The MicroSD card was not in the original package and the SD Adapter was missing. I ended up returning the product since it is not what it claims to be. I don't know if the memory was new, but it was not in the SanDisk packaging, just a click plastic case. I would avoid buying anything from "Everything But Stromboli Ltd."

WARNING USED AND NO SD ADAPTOR
By P. Paulding
It came in a plastic zip lock, not oem, once the oem package is open,it's used.. I did not pay for used memory, I also paid express shipping because I needed it in a hurry.
I also paid for the sd adaptor so I can transfer to/from pc.
the only thing I got was the express shipping.
I did not run any test on speeds, because I don't care, I am furious that this came like this and don't want it and don't trust it for my data.
