Genuine Lenovo SD Flash Memory Card - ReadyBoost (4GB / Class 6)

Pros: Well, what is there to tell. It looks and feels like a genuine Lenovo card. It's solid.
I have tested it using a USB 2.0 cardreader with hddtune 2.55. The results are as follows:
HD Tune: Generic-Multi-Card Benchmark
Transfer Rate Minimum : 14.4 MB/sec
Transfer Rate Maximum : 14.8 MB/sec
Transfer Rate Average : 14.7 MB/sec
Access Time : 1.2 ms
Burst Rate : 11.4 MB/sec
CPU Usage : -1.0%
I've read that class 6 should score a minimum of 10.0 MB/sec, wich this card scores easily. So I'm happy.

Cons: The only con I can think of is the lack of a storage case. I probably have one from another card, but if you haven't, and the card is not in the device all the time, you'll need one.

Other: Fast card, just as advertised. I can recommend this to anyone looking for a SD card of 4Gb who also needs a speedy card

Pros: SD card comes with nice packaging and really looks like genuine Lenovo. Build quality is perfect and read/write speeds also for its price. ReadyBoost works fine on Windows 7. The packaging can be used as a storage case, it has simple open/close mechanism.

Cons: Here is nothing to say...

Other: I definitely recommend it!

Pros: - It's a SDHC card, class 6 (which means it's really fast) - Ideal for usage in cameras, etc - Even works as a ReadyBoost drive in computers with Windows Vista and a card reader.

Cons: - 4 gigabytes is surprisingly little nowadays. - It doesn't work with older devices not compatible with SDHC. :(

Other: If you need a SD memory card, get this. It's large enough for most things, and it's blazing fast!

Pros: Geuine SD Card Shipped with "box" Carte SD authentique Livré avec une "boite" et embalage

Cons: SLOW! My another Micro SD card is faster than this card. Can be better LENT! J'ai une autre carte micro SD qui coute moin che et qui va plus vite que celle si. Sa peux etre mieu...

Other: Buy it if you want a slow memory card but you can find an another card cheaper and faster on DX Achetez la si vous voulez une carte SD lente, mais vous pouvez trouver une autre carte sur DX plus rapide et pour moin cher.

Pros: Low price. It is probably ok to the price compared to other products.

Cons: It is SLOW! In my opinion this is not a class 6 card - probably not even a class 4. It can not be used for video recording on my EOS 550D. All my other cards (class 4 and 6) can do that without problems. It stops recording after a few seconds.

Other: It is probably ok for normal photography in a standard camera - but useless to me, as I need it for video.

Pros: not much to say here. it's a really great card for a really great price! fits right in my gps with maps and music to go. Awesome for my euro trip this summer!
fits most other cameras and such as well.

Cons: Nothing negative to say here.
it is what it is, for a great price. could come with a plastic housing, but not needed at all...

Other: unbeatable in my country.
get it if you need it. It's fast and cheap and for this price you can get a couple.

Pros: I have used this memory card for more than one year now and have had no issues with it whatsoever. Though I did not do any speed nor authenticity tests after receiving it, it certainly is snappier than the old 128MB SD card that were installed as internal system card in my Nokia N800 which this one was meant to replace.

Cons: None really, aside from the fact that 4GB does not hold for much these days. Which is the only reason I gave it 3/5. Also, the price is a little stiff for today. When I bought it one year ago it was just fine.

Other: Authentic or not, i do not believe one bought at any retail store for double the price would make any significant change to my experience.
