Does SSD Need Power? [Internal and External SSD]

Does SSD Need Power?

SSD (Solid State Drive) is an electrical component in the computer that helps to store data in huge amounts. Like the RAM, the SSD is also a storage device designed with the latest technology to store data. Since the SSD is faster and the most preferred storage device by many, thus there are questions that most of us are curious about the whole functioning and does SSD need power to function.

The SSD is an electrical component. As previously stated, it is pretty obvious that the SSD will need power, but you may not be sure how exactly the SSD gets power. The SSD is of different types and installed as externally and internally. Each type of SSD is powered differently; you will find more about it in the article. Please keep reading to find out your answers about the SSD and its functioning with power.

Does SSD Need Power?

The obvious answer is yes. The SSD is a technology-based electrical component installed on your computer as a storage device. The SSD needs power for its function and is utilized accordingly. But does every SSD need power, and what happens to the data when the SSD loses power?

Most would worry about these normal questions, but you do not have to worry about them because you have come to the right place. So this article will give you answers.

As previously stated, different types of  SSDs are powered in different ways, and it could be the SATA cable connected to the motherboard or through a PCIe interface. Some commonly known SSDAs are SATA 2.4” SSD, SATA M.2 SSD, and the PCIe NVMe M.2 SSD. The three types of SSDs are powered in different ways.

The SATA 2.5” SSD stated first is powered through the SATA cable from the keyboard, while the NVMe M.2 SSD is powered through a PCIe interface. Still, the SATA M.2 SSD is quite different from the others because the M.2 SSDS is powered through the M.2 slots available on the keyboard itself.

Does External SSD Need Power?

The SSDS are mainly categorized into two depending on how they are installed. They are the Internal SSD and the External SSD. Besides the method used to install the SSDs, both types need power to work.

External SSD (Solid State Drive) is a portable type that requires less power than an internal SSD. External SSDs, as the name suggests, have to be powered through the output from the PC. A standard PC has 4 USB connectors, and the external SSD has to be powered through the USB connection available in your PC.

Does Internal SSD Need Power?

Unlike the external SSD, the Internal SSD is not portable; as the name implies, it is installed inside your computer. The Internal SSD is an inbuilt storage device in your computer. As previously mentioned, it could either be your external SSD or your Internal SSD; both types will need the power to store data. The commonly seen type SSD seen in the Internal SSD is the M.2 form, or the 2.5 form factored SSDs.

Does SSD Need the Power to Store Data?

In general, memory devices are categorized as volatile and non-volatile, which means the ability to store data when powered and lose its data when the power is disconnected. Volatile memory means the type can access data as long as the memory device is powered. But in this case, the SSD is a non-volatile storage device programmed using power, which means the SSD can store the data even when it is not powered.

The SSD is made of high-resistance flash memory cells and a longer period of storage time; However, the SSD can store its data without power; if the SSD isn’t powered frequently, the cells in the SSD will fade and lose their data, but since it can store data for a long period, without power it is nothing to worry about. And for obvious reasons, it is not recommended to leave an expensive SSD idle for too long.

But if you have ever given your thoughts on how long the SSD can store data without power, you will get your answers if you keep reading. The SSD can store data for more than a year if kept under 30 degrees Celsius. 

According to experts, if your SSD loses its data because you have left without power for years, you can retain the data in your SSD for at least 2 to 5 years without a power supply.

How to Retain Data from SSD  If Lost?

If the power is not supplied to the SSD for years, there are high chances you are going to lose it. However, as previously stated, you can retain the SSD data for 2 to 5 years at least. To retain the data from your SSD, you will have to use SSD data recovery software. You can retain your loss by using this third-party hard disk data recovery software.

How Much Power does an SSD Need?

An SSD does acquire much power because, unlike other storage devices, it does not have any moving parts in the device that needs the power to work. The amount needed for an SSD varies for each type as it depends on the type of SSD you are using.

On an average calculation, it could be determined that the SSD might consume 3.5 watts when using or idling. But if your SSD consumes less power, the SSD will consume less than 0.1 watts when not in use and an average of 2.5 watts when in use.


The SSD is an electrical component installed in your computer as a portable or onboard memory device. It is one of the most popular types because it is faster and holds a larger capacity for its size.

In the article, does SSD need power? It is concluded that it requires power because it is an electrical component, but as a non-volatile storage device, the SSD can still store data without power. We have also contemplated relating to how the SSD is powered for the different types of SSD, including how to retain data in the SSD when lost and how much power SSD needs.
