how many amps or watts does a samsung ssd use

[HypersleepyNaputunia]

this is in a laptop
and samsung desired is 970 evo + 1tb probably nvme

like my hdd uses 5v 0.5 amps
so it uses 2.5 watts

Depends on the Model. Interface and size will affect it. Should tell you in it's spec sheet

That's not exactly true. A Drives power is dynamic. HDDs can use upwards of 10-15 watts or so upon power on and anytime is has to do a full speed spin-up. It can also vary from model to model.

HDDs also use both 5V and 12V.

All consumer SSDs use much less power overall in comparison.

SSDs use less power and have no moving parts. Making them ideal drives for Laptops, Tablets and as an External.

we use solar power and it is winter time
laptop is a 15 watt ryzen so saving 1.5 watt gives an extra hour of on time during day

Then all your Laptops should have an SSD not a HDD. Use HDD as an external backup drive.

They should already have come with SDDs anyways. As Laptops for the past 6 years or so come with M2 SSD inside, not HDD

The cpu itself wont use a lot of power, unless you are going to use it at 100%

[Bad 💀 Motha]

Yes you could easily limit the CPU power.

is going with a smaller nvme capacity more efficient

a little but not noticeable

[Bad 💀 Motha]

No. They are generally the same power wise. Most sata ssd are just an mSATA ssd inside

Info on the 970 evo
AVERAGE POWER CONSUMPTION
(System Level)3)

250GB: Average 5.4 W Maximum 9.0 W
500GB: Average 5.7 W Maximum 10.0 W
1,000GB, 2,000GB: Average 6.0 W Maximum 10.0 W
(Burst mode)

Yup, not much difference power wise from a mechical hdd.

ok thank you looks like my 500 gb laptop hdd is going to be more efficient for some reason 2.6 watts
unless there is hidden power use in there

the main difference i think is because a SSD uses more power when writing data to the nand chips and just sips a little when reading.

[Bad 💀 Motha]

HDDs tend to use more power overall because of their mechanical parts.
SSDs only reach close to their max power during long period of heavy writes.

2.5 watts for any HDD is most likely when it is idle. They tend to use upwards of 8-15 watts during reads, writes and whenever the arm is moving around, which is most of the time. SSDs can reach a high peak, but what it takes to do that, most users on their daily usage would not be doing the kind of work with their PC that would have an SSD be doing that. As it takes mere seconds to write a couple TB worth to most SSDs, it would take many minutes for even a performance HDD to do that. So when you factor in power vs time, the HDD is always going to use more juice to do the same work cause it will always take a HDD longer.
