Buying individual memory cards gets pricey fast, but the Lexar E-Series 32GB Micro SD Card 3-Pack gives you three memory cards for about the cost of a single brand-name card. All three are Class 10 UHS-I cards rated for read speeds up to 100MB/s. That supports smooth use across a variety of applications, such as a security camera, a dash cam, a cell phone, or a handheld gaming console. Each card includes full-size SD adapters, so it works with older cameras and laptop card readers.
Head over to Amazon to get the Lexar E-Series 32GB Micro SD Card 3-Pack for just $36, down from its usual price of $43. That’s a $7 discount and 16% off.
A micro SD card 3-pack with an abundance of extra storage space
Using three microSD cards is a good idea because many small items in the average house use a microSD card, and each one wants its own. If you’re going to put a card in your dash cam, your doorbell camera, and a Raspberry Pi, consider using a different card in each so you don’t have to keep moving a single card between them. A second card in a glove box doesn’t cost much but saves you from losing most of your data if a card fails while you’re traveling.
The Class 10 and UHS-I ratings mostly refer to sustained recording. Both require a minimum write speed of 10MB/s and sustain it for extended periods, allowing uninterrupted recording of 1080p video. Cards rated lower than these may skip frames or stop recording once the internal buffer fills. Anyone can agree how frustrating that is, especially when you’re about to view what happened. Loop recording constantly requires high write performance, so it’s reasonable to conclude that a lower-rated card will begin to fail prematurely.
Transferring data off a memory card after an event is typically time-consuming. With read speeds as high as 100MB/s, however, that same data transfers in minutes rather than hours. It’s also quicker to copy an entire memory card to your computer and faster to review video recordings from your doorbell camera.
The decision to produce each card as 32GB resulted from multiple factors. Many newer dash cams and older cameras limit support for larger cards to no more than 32GB. Other devices such as the Nintendo 3DS have similar limitations. It’s easy to see the importance of using a card compatible with the application, since a 256GB card is worthless if the hardware can’t mount anything larger than 32GB.
Each card includes a full-size SD adapter, so you can install the microSD card in a DSLR, a laptop card reader, or anything else built around the larger format. That way you don’t need to purchase additional adapters separately. More importantly, since those adapters are included, you can take a card originally purchased for a dash cam and use it with a different piece of equipment two years later. Lexar provides a limited lifetime warranty on each of the three cards in the package.
