1 GB SanDisk MicroSD TransFlash Memory Card (Bulk)

I bought this card from BlueProton. Small-block random writes were very slow, and this spec may possibly be important if you're running your OS from the actual card (Nook Color CM7 from SD, etc), but I was intending on just using it as a bootable Clockworkmod Recovery SD anyway. Benchmarks are below for the card, and were taken on an internal card reader that's connected via USB to my mobo, prior to having written any data to the card. It gets Class 4 performance (which measures only sequential write speed), if that's important to you. It did come with a small plastic case.-----------------------------------------------------------------------CrystalDiskMark 3.0.1 (C) 2007-2010 hiyohiyo Crystal Dew World : [...]-----------------------------------------------------------------------* MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 4.371 MB/s Sequential Write : 4.426 MB/s Random Read 512KB : 4.369 MB/s Random Write 512KB : 1.938 MB/s Random Read 4KB (QD=1) : 2.164 MB/s [ 528.2 IOPS] Random Write 4KB (QD=1) : 0.026 MB/s [ 6.2 IOPS] Random Read 4KB (QD=32) : 2.207 MB/s [ 538.8 IOPS] Random Write 4KB (QD=32) : 0.028 MB/s [ 6.7 IOPS] Test : 50 MB [J: 0.0% (0.0/941.7 MB)] (x5) Date : 2011/05/06 23:43:34 OS : Windows XP Professional SP3 [5.1 Build 2600] (x86)

Cingular sells this card online with its phones (like the LG CU500 I just bought) for $49.99 delivered. Digital Media Source, the Amazon Marketplace partner, sells the bulk version for $25 delivered. It comes quickly by first class mail and the delivered price is still half that of Cingular.Cingular apparently sells and recommends the actual SanDisk card with the CU500 because of many reports that other manufacturers' cards don't work with it. Personally, I think that this is either a manufactuing quality issue or a user-installation issue (not seating the card properly), because all MicroSD cards should meet the same standard. Nevertheless, Cingular sells and recommends the SanDisk card, and the Cingular user forums seem to have basically no complaints about the SanDisk product and random complaints ("My Kingston card didn't work" "Mine did." "Well, mine didn't" etc.) about cards from other manufacturers with regard to the CU500. Sandisk invented the concept of MicroSD and is a manufacturer with a reputation for the highest quality, so the big complaint on the forums about having to use the SanDisk card is that it is expensive.So SanDisk it is if I want a minimal hassle. But of course that $49 price from Cingular is frustrating when you can get a non-SanDisk 1GB card from a site like Newegg for $17. Enter the best of both worlds from Amazon: an actual no-kidding *official* SanDisk card for $25 delivered. Now that's worth my money. The only concern that one might have is that all you get in the little envelope from Digital Media Source is a little soft plastic container with the Sandisk card and an adapter in it. That's it. No instructions. No other information. Nada. However, given that Cingular provides detailed instructions online as to how to install the card in your particular phone (like my CU500), you don't need anything more. I am totally happy with my purchase, which arrived at my door in NYC 3 days after I ordered it (one day for the USPS to get it here, 2 days for Digital Media to send it). Highly recommended.

Got this little number to put in my cellphone (LG VX8300) and it works perfectly. Format the micro card in the phone, insert it into the SD adapter, slide the adapter into a reader, drag 'n drop pix & tunes into the appropriate folders, re-insert micro card in phone, and voila!You will want to be very careful using this micro card no matter where you buy it; it is tiny and not too rugged. Just exercise due caution and insert & eject it over a table or other surface. Once you have it inside whatever device it's going in, you're fine; on its own it is somewhat vulnerable.The "bulk" card works perfectly, probably having the exact same defective rate as retail packaging, only you pay about 40% less. At $9.59 from Blue Proton, this thing is a steal; a little less so after they tack on $7.20 in shipping (!!). However the total cost is still worth it, and BP's shipping (USPS First) was fast- it arrived on the fourth business day after the order.Highly recommend this product. However, be aware that the VX8300 can take up to a 2 GB card, so if you have lots of music, you may want to consider the larger capacity card instead.

Freakishly simple, effective and well designed. I got it for my LG AX8600 cellphone (Alltel's version of the LG VX8600), and after a bit of worry (the SanDisk MicroSD is not built like a tank) I finally took the plunge and stuck it in my phone. A neat click -- on my phone you remove it by pressing on it again so that it will eject -- plus a simple format process and the little MicroSD card was ready for photos, video or music. To load or delete files place the MicroSD into a transflash adapter, then put the transflash into a  SanDisk SDDR-103 MobileMate SD+ 5-in-1 Mobile Reader (SD/ MiniSD/ MMC/ RS-MMC/ TransFlash, Retail Package) , which you plug into your computer's USB slot. From there you drag and drop whichever files you choose (though my phone does not seem to see mp4s.) Overall a great package.
