MicroSD Card VS SD Card

Similarity

Firstly, SD and microSD cards share the same standards. To be specific, SD cards include SDHC, SDXC, and SDUC, while microSD cards contain microSDHC, microSDXC, and microSDUC. The standards of each SD memory card and their corresponding capacities are listed in the table below.

Tips:

1. The capacities of microSD card types are identical to their full-sized (SD) cards.

2. To find the difference between SDHC and SDXC, simply read this post.

Type Capacity
SD 2GB (maximum)
SDHC/microSDHC 2GB to 32GB
SDXC/microSDXC 32GB to 2TB
SDUC/microSDUC 2TB to 128TB

Secondly, both SD and microSD cards work in the same way. Thirdly, the two cards are affordable, available in a variety of storage sizes, and can transfer data quickly.

Difference

The form factor is the biggest difference between SD cards and microSD cards. Compared with SD, microSD is more versatile because it often comes with an SD adaptor which allows you to use microSD cards in hardware devices that only support SD cards.

To use a microSD card in a device that takes standard SD cards, you need to slide the microSD card into the adapter’s card slot and then insert the adapter into your device. If you use a microSD card on the computer, you can use a USB plug-in adapter if the PC doesn’t have a standard SD card slot.

Tips:

The adapter looks almost identical to a standard SD card.

However, you can’t use an SD card on devices that require microSD because it’s too large to fit inside the microSD card slot. Though there are SD-to-microSD adapters, they usually are sold separately and could be less secure in certain devices.

All the standard SD cards come with a tiny locking toggle that enables/disables you to write or delete data on the card. Differently, miniSD and microSD cards don’t have that. Besides, microSD has a smaller dimension than standard SD cards.

MicroSD vs SD: what’s the difference? The table below shows you the answer.

MicroSD vs SD Card: Which One to Select

SD vs microSD: which one to pick? Well, microSD cards are preferred by many users. Why? As mentioned earlier, microSD cards are more versatile as they are sold with an SD adapter. With that adapter, you can insert the microSD card into regular SD card slots.

For devices with the microSD slot, you can directly insert the microSD card into them without the adapter. Besides, the microSD usually costs less than a regular SD card of the same brand and specs because of its smaller size.

Though SD cards are unlikely to be phased out very soon, they may become inconvenient over time if PCs and newer devices prefer the microSD slot. Using a microSD card to transfer data to and from a phone is fast and convenient. MicroSD vs SD card: which one to choose? It depends on your device.

Here are some recommendations for microSD/SD cards. According to your needs, pick one randomly.

Format/Partition SD/MicroSD Card Before Using It

Generally speaking, you can’t directly use a new SD/microSD card. Instead, you should format or partition the card first before using it. Moreover, you are required to format the memory card in a certain format before using it on some devices. To manage your microSD/SD card, you need a disk managing tool like Disk Management (DM) and MiniTool Partition Wizard. Here are the steps to format and partition SD/microSD cards on the two tools.

Tips:

Before starting the process, plug the SD/microSD card into your Windows PC.

Option 1: Use Disk Management

Disk Management is an embedded utility in Windows PCs, allowing you to create/format/extend/shrink/delete partitions, initialize disk drives, change drive letters and paths, convert to MBR, etc.

Step 1: Right-click on the Windows icon and then click Disk Management in the Start menu.

Step 2: Right-click on the SD/microSD card and click Format. If the memory card is not partitioned, you should partition it first. To do that, right-click on the card, click New Simple Volume, and then follow the on-screen instructions to finish the process.

click on the Format option

Step 3: In the next window, set partition parameters like volume label, file system, and allocation unit size based on your needs. Then click OK to save changes. If you are prompted with a warning window, click Yes to confirm the operation.

Tips:

click OK

However, Disk Management may prompt you with errors like console view is not up-to-date, system reserved partition not showing, format option greyed out, extend partition grayed out, and other issues. In this case, you can try Disk Management alternatives.

MiniTool Partition Wizard is an ideal replacement because it includes almost all the features of Disk Management. Besides, it boasts some features that can’t be found in DM such as Surface Test, Disk Benchmark, Space Analyzer, Data Recovery, and so on.

Option 2: Use MiniTool Partition Wizard

With this powerful partition manager, you can manage hard drives, USB flash drives, SD/microSD cards with ease. For instance, you are able to perform an SD card speed test, surface test, disk benchmark, and other operations on these storage devices.

Here’s the tutorial on how to use MiniTool Partition Wizard to format a microSD/SD card.

Step 1: Download and install MiniTool Partition Wizard on your computer, and then launch the program to enter its main interface.
