eMMC and SSD storage share many things in common as they both adopt the technology of NAND flash memory for example, and you can find some laptops using either eMMC storage or SSD storage. Nonetheless, do you have a general concept of eMMC and SSD? If by chance, your computer or laptop storage needs expanding or altering, which storage drive are you going to invest money?

Here you go. To present you with the remarkable differences between eMMC and SSD storage, we reviewed eMMC vs. SSD in several critical aspects, such as storage components, capacity, price, speed, application, performance, etc.

eMMC vs. SSD FAQs:

1. What Is eMMC
2. What Is SSD
3. eMMC vs. SSD: Which Is Better
4. Can eMMC Be Upgraded
5. How to Replace eMMC with SSD

What Is eMMC

eMMC stands for embedded MultiMediaCard. If you got previous knowledge about Secure Digital (SD) devices, you should know that eMMC derives from MMC, while MMC is the precursor of SD devices. MMC still exists but we're supposed to hear of eMMC more often.

eMMC appearance

Technically speaking, eMMC consists of a controller and NAND flash memory, both of which are located in one integrated circuit. Since it's flash memory-based, it requires little to no power to retain data. Meanwhile, the "embedded" means that eMMC storage chips are directly soldered on a device's motherboard, just like fastened to a body part.

The eMMC is characterized by cheap, small, power-efficient, quiet and durable, so it is widely used on phones, tablet PCs or some budget laptops, notebooks or 2-in-1s.

What Is SSD

Whereas SSD, which refers to Solid-State Drive, is the other type of NAND flash memory product. Yet adopting the NAND flash memory, SSD and eMMC serve for quite different purposes, as the core technology is far from the same. 

SSD appearance

First of all, the key components make up an SSD include a flash controller, a number of NAND flash memory chips and a circuit board; second, it is functioning as removable/secondary storage in a hierarchy of computer storage by connecting via closure or SATA power cable.

Even SSD boasts itself smaller, thinner and lighter than a Hard-Disk Drive (HDD), it's still bigger than eMMC in volume size and heavier in weight. And most of all, it comes with a larger capacity. Therefore, SSDs are usually found in rich-featured laptops and desktop computers.

eMMC vs. SSD: Which Is Better

By viewing the broad introduction of each term, we know that eMMC and SSD flash memory storage are developed for particular markets. When it becomes to choosing one for your own storage device, you should be aware of three substantial differences, including speed, capacity, and price. And in point of fact, nothing compares to match your own demand.

emmc vs. ssd

1. Transmission Speed

SSD stands out from many storage drives including eMMC. It's de facto the fattest compared with HDD, fusion drive and other storage forms under the same specification.

The data transfer speed of eMMC has been improving all the time but almost reaches the upper limit due to the 1,4,8 bit bus width it defines. It doesn't have to say that eMMC is slow, but it is indeed lack of potential to be faster than 400MB/s, whereas SSD does.

eMMC data transfer speed:

  • eMMC 4.41 104MB/s
  • eMMC 4.5 200MB/s
  • eMMC 5.0 400MB/s

Higher-performance SSD data transfer speed:

Read speeds are ranging from 500MB/s to over 3,000MB/s
Write speeds vary from 300MB/s to over 3,000MB/s

2. Data Capacity

eMMC packages the NAND flash chip and control chip into one chip so as to simplify the memory design and further reduce the components. That's not hard to tell why it's mainly applied in mobile devices and compact notebooks. In accordance with the exclusive design, it is usually not that big enough for large size files or bulk storage.

eMMC capacity:

  • Popular capacity 32 GB and 64 GB
  • Available capacity 128GB and 256 GB

* Larger size over 128 GB are rarely seen these days
* eMMC supports a microSD card connection as an expandable storage

Since SSD is intended to replace the role of HDD by offering greater performance in boot time, and opening files or programs, it cannot lag too far behind regarding the storage capacity. Even less larger than that of HDD, the most common operational storage of SSD starts from 128GB.

SSD capacity:

Between 128 GB and 1 TB

3. Price

If you've read reviews on websites, you'll learn about one truth of the SSD value. Better performance but higher cost. It seems to be a unified label putting on a Solid-State Drive. So how costly is it? 

Roughly $0.20 per gigabyte. Taking the same amount of money, if you buy a 1TB SSD, it's enough to buy a 4TB HDD or even bigger.

By contrast, due to the unit price and the total capacity, the money you spend on an eMMC device would be dramatically dropped. It's undeniably inexpensive even for that of 128 GB and 256 GB.

Can eMMC Be Upgraded

According to all the primary perspectives by viewing eMMC vs. SSD, eMMC provides a budget laptop with a favorable price, which would be capable enough to let you surf the internet or watch some streaming videos. Is eMMC better than SSD now? The truth is eMMC doesn't have the firmware, multiple flash memory chips, high-quality hardware, and fast interface, it's restricted within the application on ultra-portable and consumer digital devices, perhaps will last for a long time.

Anyway, SSDs come with relatively bigger volumes and faster transmission speed, it's the exceptional choice for fully-featured laptops and desktops that provides the best user experience for booting the operating system, playing games, handling extremely large files or retaining a bulk storage.

What if eMMC has currently run out of your needs on your PC? Can you upgrade eMMC with SSD without making an effort? If that's what you want right now, go to find an accomplished disk cloning tool.

How to Replace eMMC with SSD

Once you set your mind to replace the eMMC storage with a Solid-State Drive, of which the price has been decreased year by year, do not hesitate to download EaseUS Partition Master on your laptop. It's a versatile disk & partition management tool that enables Windows 10/8.1/8/7/Vista/XP users to manage a variety of hard drives in every way.

Let it be HDD, SSD, eMMC, USB thumb drives, memory cards or whatever devices that can be correctly recognized by Windows operating system, you can take a full control of the storage by resizing/moving a partition, formatting, deleting, wiping data, migrating OS, copying/cloning a disk or partition, etc.

Now the point is, you're going to utilize the "Clone" feature to swap the present eMMC with an additional SSD. It won't take extra time and energy to get the whole process done as long as you follow the user guide carefully.

Step 1. Select the source disk.

  • Go to the "Clone" tab, click "Clone OS Disk" or "Click Data Disk". And then click "Next" to continue.
  • Select the source disk that you want to copy or clone. Then, select "Next".

Step 3. Select clone mode.

You can select "Autofit the disk", "Clone as the source" to customize your disk layout.

Step 4. Click "Start" to start cloning process.

To make full use of the SSD in the future and give upon the eMMC, remember to keep only one storage drive (the new SSD) on your laptop. Otherwise, one drive will be marked as offline automatically by Windows.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
