Possibly, but the drive alone does not tell you whether your whole PC’s electricity bill will change noticeably. An SSD may use less power than a rotational hard drive, but the actual cost of looping YouTube depends on the complete computer and playback conditions. To find your system’s cost, measure its wall power while it plays and use your own electricity rate.
Why a drive’s power use is not the PC’s electricity cost
Microsoft’s Windows Server hardware power considerations says SSDs are more power efficient than rotational drives. That is a general direction, not a quantified result for a consumer PC looping YouTube: it does not say how many watts an SSD saves in that situation or how much the bill would fall.
The drive is only one part of the system. The processor, graphics hardware, display, browser, network connection and playback workload also contribute to electricity use. A drive-level specification therefore cannot be treated as the PC’s total draw or as a reliable estimate of a bill difference.
What published SSD figures can—and cannot—tell you
SanDisk Support publishes generic theoretical ranges for internal SSD power use. The figures below are not measurements of particular SanDisk products, do not compare an SSD with an HDD, and do not represent a whole PC playing YouTube. SanDisk says it does not publish power-consumption information for its own products and presents the figures as general expectations in its SSD power-consumption guidance (published October 23, 2024; updated May 31, 2026).

| Drive category or activity | Generic figure published by SanDisk Support | What it describes |
|---|---|---|
| 2.5-inch SATA SSD, idle | 0.30–2 W | Generic theoretical idle range, not a YouTube playback or whole-PC measurement. |
| M.2 SATA SSD, idle | 0.40–2 W | Generic theoretical idle range, not a YouTube playback or whole-PC measurement. |
| M.2 NVMe Gen 4.0 SSD, idle | 1–3 W | Generic theoretical idle range, not a YouTube playback or whole-PC measurement. |
| Internal SSD, reading or writing | Can reach 6–10 W, depending on form factor and operation | Generic possible active-use power, not a matched HDD comparison. |
Idle and read/write figures describe different drive activity. Neither establishes how much a particular drive contributes while the rest of a particular PC plays a video. The cited figures also provide no matching HDD values, so they cannot be used to calculate an SSD-versus-HDD saving.
Playback conditions can affect the comparison
YouTube says playback quality can depend on connection speed, player or screen size, the quality of the uploaded video and browser support. On a computer, you can manually select video quality. Its video-quality guidance explains these factors.
Rank #2
- 5-in-1 Connectivity: Equipped with a 4K HDMI port, a 5 Gbps USB-C data port, two 5 Gbps USB-A ports, and a USB C 100W PD-IN port. Note: The USB C 100W PD-IN port supports only charging and does not support data transfer devices such as headphones or speakers.
- Powerful Pass-Through Charging: Supports up to 85W pass-through charging so you can power up your laptop while you use the hub. Note: Pass-through charging requires a charger (not included). Note: To achieve full power for iPad, we recommend using a 45W wall charger.
- Transfer Files in Seconds: Move files to and from your laptop at speeds of up to 5 Gbps via the USB-C and USB-A data ports. Note: The USB C 5Gbps Data port does not support video output.
- HD Display: Connect to the HDMI port to stream or mirror content to an external monitor in resolutions of up to 4K@30Hz. Note: The USB-C ports do not support video output.
- What You Get: Anker 332 USB-C Hub (5-in-1), welcome guide, our worry-free 18-month warranty, and friendly customer service.
YouTube’s system requirements also notes that some movies, shows and live streams need more processing power, and recommends higher sustained connection speeds at higher resolutions. If you compare two drives or two PCs under different playback conditions, a difference in measured power cannot automatically be attributed to the storage drive.
Measure the cost for your own setup
For a useful estimate, measure the complete PC at the wall during representative playback. A plug-in power meter can measure the whole system; the sources cited here do not establish a particular meter model or its accuracy. Keep the test conditions consistent, and use your actual electricity price per kilowatt-hour.

- Choose representative playback. Use the YouTube video, resolution and browser you normally use. Keep the display and other connected equipment in the same configuration.
- Measure whole-system power. Record the PC’s average wall power during the loop, rather than relying on the drive’s specification alone. Allow playback to settle before recording a representative period.
- Convert watts and hours to energy. Calculate kWh as average watts × hours ÷ 1,000.
- Apply your electricity rate. Multiply the resulting kWh by your own price per kWh. For a daily or yearly estimate, use the hours you actually expect the PC to run over that period.
- For a drive comparison, change only the drive if possible. Use the same PC, video, resolution, browser and display configuration, and repeat the measurement. Treat the result as specific to that system and test—not a universal SSD saving.
If you compare separate computers instead, their other hardware and settings may differ too. In that case, the result is a comparison of those complete systems, not an isolated HDD-versus-SSD test.
Should you buy a 2.5-inch SATA SSD just to lower this bill?
The available figures do not establish a whole-PC saving, an annual amount or a payback period for this use. A 2.5-inch SATA SSD may be a relevant storage upgrade for other reasons, but the evidence here does not justify buying one solely to cut the electricity cost of looping YouTube. Measure your system first if electricity cost is the deciding factor.
