In previous article, I mentioned RGB VS YCbCr but in this article, I have mentioned difference between eMMC and SSD storage.
Storage type and capacity are essential considerations when purchasing a device. It will not be surprising if you are split between choosing an Embedded Multimedia Card (eMMC) or a Solid State Drive (SSD).
Both storage types are different, and it isn't easy to choose one over the other if you don't know how they differ.
Fortunately, here is a piece that pits eMMC and SSD against each other, giving you a detailed explanation of both and comparing their features. The information you will get here will help you know which one you need and why you need it. Read on!
What Is eMMC?
Embedded Multi-Media Card (eMMC) is a solid storage device that is embedded or fixed to the circuit board of its host. It is a solid storage device because it has no moving parts that reduce its speed or cause it to heat up.
eMMC is permanently attached to the circuit board of its host device - not removable, which makes it perfect primary storage for phones, tablets, and some computers. It uses NAND flash memory, a component that allows it to retain data without requiring power.
Since it has NAND flash memory, it operates very fast. However, it is not upgradeable because it attaches to the host device's motherboard. You get an SD card slot to expand the storage to compensate for this.
Pros Of eMMC
Here are some of the advantages of eMMC:
- It is much smaller than other types of flash memory because it does not require a separate controller chip.
- Because of its size, it is suitable for smaller devices.
- It is less expensive and reduces the cost of its host device.
- It has no movable parts.
- It offers SD card slots for expansion.
Cons Of eMMC
The disadvantages of eMMC include:
- It is slower than other types of flash memory.
- It is for low-end or budget devices.
- It may not be compatible with all devices.
- It offers a maximum storage size of 128GB.
- It delivers transfer speeds of up to 400MB per second.
- It is permanently soldered to the motherboard of its host, making it hard to replace.
What Is an SSD?
A solid State Drive (SSD) is a solid storage device like eMMC. However, it is not embedded in its host's motherboard but is attached to the motherboard with a ribbon cable. This ribbon cable connects the SSD and motherboard via a SATA, mSATA, or PCIe interface.
It is detachable from the host device and upgradeable since it is not permanently attached like eMMC.
Pros Of SSD
Below are some features of SSD you would enjoy:
- It is faster than other types of flash memory.
- It is less likely to suffer from data corruption or physical damage.
- It offers as much as 1TB of storage space.
- It is for high-end devices.
- It is not permanently attached to its host's motherboard, making it easy to remove and replace.
- Its storage space is upgradeable.
- It offers data transfer speeds of more than 3GB per second.
Cons Of SSD
- Here are some of the drawbacks of SSD:
- It is typically more expensive than eMMC.
- It can be affected by extreme temperatures.
- It is not suitable for smaller devices because of its size.
- It consumes slightly more power than eMMC.
Features Comparison For eMMC And SSD
The table below compares the features of eMMC and SSD:
Flash memory is embedded in the host device's motherboard.
A solid-state device is connected to the host device's motherboard by ribbon cables.
Type of storage
Temporary storage for portable devices.
Permanent storage medium.
Portable devices and low-end laptops.
Computers and laptops.
are Faster for storage and retrieval of small files.
Slower for the storage and retrieval of small files.
Slower for the storage and retrieval of large files.
Faster for the storage and retrieval of large files.
A maximum speed of 400MB per second.
A maximum speed of between 200MB per second and 1500MB per second.
Choosing between eMMC and SSD should base on the type of device. For example, it is not advisable to purchase a computer that uses eMMC unless you are ready to work with its likely slow speed.
