Acquiring Hardware would be an interesting problem.
However, there are quite a lot of SSDs out there. Instead of SK Hynix I might go with Samsung, or maybe try a stick of WD, Kingston, Sandisk or Toshiba.
As I said, there are lots of variables and even the same company may produce sticks with drastic different power consumption/ratings, let alone different ones.
Speaking of power …
WD Green SN350 have 3.5W max and 5-25mW sleep/idle.
WD Blue SN550 have 3.5W max and 5-30mW sleep/idle.
WD Blue SN750 have 4W max and 5-30mW sleep/idle.
WD PC SN730 have 6.27W max and 3.5-30mW sleep/idle.
WD Black SN750 SE have … hm. They don’t tell you.
WD Black SN750 have 9.24W max and 3.5-70mW sleep/idle.
WD Black SN850 they don’t tell you …
WD Black Call of Duty®: Black Ops Cold War Special Edition SN850 shuld just be a regular SN850. Again, they don’t tell you.
WD PC SN810 have no details.
WD IX SN530 have 5.5W max and 3.5W average.
WD CL SN520 have 5.8W peak, 2.5-25mW sleep/idle.
WD Red SN700 have 9.24W peak, 3.5-70mW sleep/idle.
WD PC SN530 have … hm. 75mW active, 5-20mW sleep/idle.
Samsung is … hm.
Listed by amount of power consumed, in increasing order:
(ugh my pentium 6405U is struggling to render the webpage)
980 PCIe 3 (4.3W average)
970 Pro (5.2W, 8.5W burst)
970 Evo Plus (5.8W, 9W burst)
970 Evo (5.7W, 10W burst)
no data on 980 pro. All drives are either 500GB version or 512GB version.
All the 970 have 30mW idle, 980 PCIe3 have 45mW.
A 860 SATA 500GB have 2.5W write, 4.0W burst and … no data on idle. So yeah. there you go.
Kingston’s DC1000B here have 1.90W idle, 1.81W read and 5.47W write.
Their NV1 here have 5mW Idle (wtf), 1.1W Read and 3.3W Write.
And the Fury here have 5mW Idle, 2.7W Read and 4.1W Write.
My thought is that the DC series are crunching numbers because they are self-encrypting (among other things)
Note that the “max” power is the absolute maximum (10us) and happens during, say, drive bootup/refresh (perhaps charging up internal capacitor/grid for clearing blocks). Normal write is about half of that, and normal read is about 1/4 of that.
Also note that WD have a “sleep” power consumption and an “idle” power consumption. These have to do with different sleep states (S3/S4 respectively). You can assume it’s the high number when the system is on and the low number when the system is sleeping.
Further note is that a faster drive (e.g. Samsung 970 Pro) will be able to finish read/write operations faster (or don’t have to work as hard) than a slower drive (e.g. WD Green SN350) and therefore enter sleep/idle early, affecting total power consumption.
