32GB Micro SD Card, Full HD Video for Wireless Security Camera,Tablets, Security Bullet Cameras for Storage, Laptops, Desktop Computers, TMEZON

Based on my speed testing detailed below, this micro SDHC card has a WRITE speed hovering around 30MB/S and should provide good HD videos if compatible with your device. The product advertising webpage says, Write speed: up to 15MB/s, but the SDHC card I received actually did WRITES at twice the speed indicated on the webpage, much to my delight. The delivered card exactly matches the image on the product advertising webpage and has clear minimum write speed classifications: C10 and U1 (see below for meanings). All micro SDHC 32GB cards are the same, right? Not so. I compared 3 cards which came with recording devices I ordered from Amazon and 3 cards I ordered for evaluation as possible replacements or backups. These micro SD cards are tiny, can easily be lost, can wear out over time or experience failures. Background Info: Micro SD are used in cell phones, dash cams, cameras, security systems, etc. They can hold a lot of data as well as recording with HD quality. SDHC stands for Secured Digital High Capacity – up to 32GB. SDXC = Extended Capacity – up to 2TB. SDHC can function at different read/write speeds and here is where one SDHC 32GB is not necessarily as good as another, even if they look and are marked identically. There is Rated Speed (r/w), Speed Class Ratings (Cn), Ultra High Speed Ratings (Un) and Video Speed Class (Vn). E-device manuals identify supported speed ratings needed. The Class (Cn) specifies the minimum write speed the card will support. They can and usually write faster. Quality SDHC cards should be marked with the storage capacity, and Cn, UHS, or Vn and other markings I am not concerned with here. If the card is not stamped with either the Cn, Un or Vn code, you will have to test it or skip it. C2 = 2MB/S C4 = 4MB/S C6 XX V6 = 6MB/S C10 U1 V10 = 10MB/S XXX U3 V30 = 30MB/S XXX XX V60 = 60MB/S XXX XX V90 = 90MB/S Note: You need C10/U1/V10 as a minimum for 1080p – 4k video (HD quality). IF YOU ARE STILL WITH ME, HERE IS WHAT I DISCOVERED WITH THE 6 SDHC 32GB CARDS I TESTED. Firstly, I did HD video recordings on them and I could not tell any difference in the quality of the recordings – no stutter – no jerking. Perhaps a professional photographer could. The reason is because all 6 had write speeds of 20MB/S or better and 10MB/S is sufficient for good HD video. Secondly, I found the following MB/S write speeds: 20, 22, 24, 30 (marked C10 U1), 34, and a screaming 50. All 6 were marked 32GB but 5 had no other markings, all 6 were identified by Windows as SDHC, only 1 had speed markings. CONCLUSION: When it comes to micro SDHC cards, you cannot tell a book by it’s cover when it comes to the most important feature – write speed.

Good SD card. Works as expected. No issues so far. Using it on a tablet.

Bought this for my video doorbell, works great.

Picture quality for my dashcam recordings is great! 32GB is the max for my dashcam storage so this works perfectly. I recommend this memory card for any dashcam or camera.

using this on my solar PTZ camera and so far it is playing back the recordings, so 2 thumbs up.

Worked perfectly in my security camera for onboard storage. Formatted with no issues and speed tests also show good write performance for a single video stream from the camera. Read performance was also better than expected seeing as this is a slower card, but great for its intended application.

i can only use 27.5gb of 32gb.

Works in my bluetooth headphones, smartphone, speakers, mp3 player, tablet and trail camera. I used a card reader and could access the files on my computer. I havent had any issues with it, but it hasnt been used every day. Ill update this review if anything changes my mind on this product.

I have not had any issues with this card. I use it in my dash cam and it works flawlessly.

This card is working out fine, I put it in a inexpensive camcorder that I bought for my kids to make videos with.
