This HP 256GB mx330 Class 10 U3 microSDXC Flash Memory Card is awesome. I used it to do a backup of all of my files, important home and car stuff, all my music which is a gigantic collection and everything else and I still have room. It is tiny and lives in my purse un case something happens like a fire and I need access to anything.Also this can be inserted in your Nintendo switch to make it way more functional.

Once I got the package open it was very easy to use. I had a camera that would accept the larger memory card in the adapter. I was able to take pictures with it easily. It worked well with my card reader. It was easily plug and play.I received this product to try for free from the Walmart Spark reviewer program in exchange for my honest review. The opinions in this review are 100% my own.

The HP Micro SDXC mx330 with adaptor is a perfect companion if you are both a stills photographer and a videographer. Being an SDXC format means that capacities are more than 32GB (up to 2GB). I chose the 128 GB variant which would be sufficient for my needs.Also, I preferred the micro format too since the HP mx330 includes an adaptor. This way the sdxc card can be versatile in the sense that aside from my camera I can use it on my business laptop which does not have a regular sd card slot but a micro sd card slot and for Android phones too.This card also has a transfer rate of 100 mb/s which for my needs is sufficient transfer rates for HD video and even up to 4K.

But having 128 GB takes the cake as I can use my camera as a videocam or if I decide to use this as extra storage for my laptop by mounting it. I would no longer need to break open my laptop to include an SSD. And for the most part the speed would suffice. Of course there are much faster SDXC cards out there but for the average user 100 MB/s would suffice.Do note that this micro sdxc card is made by PNY for HP. Don’t know PNY? Well PNY is a leading manufacturer of SD cards. So be assured this is a quality product. I have included also a picture of this together with my camera which is capable of taking 4K videos. Definitely, I would recommend this for others.
I am happy to have this! These things are so tiny I was worried I was going to lose it before I got it to my camera hah. I use it for my Baby monitor (which is actually a WiFi security camera). It doesn’t have cloud or other recording UNLESS you use a micro SD card. I can now go back and see what time she woke up (she’s quiet when she wakes). It’s big enough that I’ve been able to record at least a weeks worth of footage (24 hours a day) so it’s plenty big enough for me. It’s nice to have this option to view the playback on my camera! It was a little hard to insert into the camera (not the cards fault, it’s just a tiny slot in the back so I had to use the edge of a spoon to “click” it into place). Overall very happy with the quality, packaging, and size of the card.
I received The HP mx330 U3 microSDXC Flash Memory Card, 128 GB. I've been using the card on my Samsung phone and it works great! The card inserts and removes easily, no sticking. And this card is fast, very good quality! I mostly use my card so that I can store massive amounts of photos and videos, and not have to deal with deleting anything to make space. This card is so much better than using the 32GB and 64GB cards I've used in the past. Best memory card I've had. It should definitely meet, if not exceed your expectations like it did mine. I definitely recommend this HP Memory Card.
I just received the "HP mx330 U3 microSDXC Flash Memory Card, 128-512GB" from the Walmart sparks program. This little SD card is exactly what I have been needing! I have soo many photos on my phone and need the extra storage space for all of them instead of constantly having to connect my phone to my computer and transfer them over. I got the 128GB SD card and this should be able to hold tons of pictures,music, or documents for a long time. I was using a 2GB SD card and it filled up often enough to annoy me. With this 128GB SD card I definitely won't have to worry about dumping photos every so often. It comes as a two piece set. A micro SD card and the adapter both come in this little package. This SD card is compatible with smartphones, cameras and some tablets. I ... MoreI just received the "HP mx330 U3 microSDXC Flash Memory Card, 128-512GB" from the Walmart sparks program.

I also really like that it comes with the adapter because I can go from using it in my phone to plugging it into my camera or laptop when needed.
I have been looking to get a bigger memory card for my phone but couldn't decide on what to get. I was debating on getting the Sandesk or Samsung since I have a samsung phone but both were very pricey and then I found this little guy.. I think the HP Memory Card works the same as the other more expensive cards. I do trust HP as they are well known to make great quality products. I moved all my pictures, documents etc without trouble and I have been using thos for almost 3 weeks now without issue..Definitely worth the buy!! And oh...shipping was very very fast..buy it!! You wont regret!
So far, I have enjoyed using this microSDXC card! The quality of this card is really nice. Also, it's durable! That may sound weird for an SD card, but it really is durable and withstand a lot. This card is super easy to use too. All you have to do is put the micro card into the adapter, if you want to use it for older devices that only use the regular SD card. Then, you put the memory card into your device and VOILA! I personally only use the microSD card because the devices I am using it for only use that kind. I use this in my gaming device, and it works really well! I am so happy to have more storage on my device!This card is versatile too! You can use it in cameras, phones, tablets and some gaming devices! It can read up to 100 mb per second too, so it's fast ... MoreSo far, I have enjoyed using this microSDXC card!

So, if you have an action camera, this would be perfect for you!All in all, I highly recommend this microSD card to everyone! You get a ton of storage with it, and it is versatile too. It's just an all around great way to get extra storage! Give it a shot, you won't regret it!
I like this SD card. It works really good. It was very easy to use. Just put it in my device. And it worked right away. I was able to do it in less than Five minutes. And removing it from my device was easy too. The adapter fit right into my computer so that I was able to load my pictures on it so easily. And it was easy to use it to remove pictures to my laptop also. And I was able to print out some of the pictures and the quality was very nice.I like how much I can save on it. It is One Hundred Twenty Eight GB of storage. The SD card has up to One Hundred MB per second read speed, But writing speed is lower. And it is rated U3 for 4K Ultra HD video recording.One thing I do not like is that the adapter does not have a case to store it in. I prefer to have a ... MoreI like this SD card.

I prefer to have a case so that the adapter does not get any damage to it. But the adapter does seem durable. I do not think that it would break very easily.It says on the package that you can use it in any tablet, cell phone, or camera that has an SDHC/SDXC card slot with the included adapter. But I did check online to see if my phone was compatible since it has the capacity to save so much on it. And that my phone would be able to handle the speed that it uses.
