Power Measuring several SSDs (Crucial, Kingston, Apacer)

I was curious if the widely used Crucial BX 500 did also "fail" as 480 GB model. And actually it shows the same picture as the 240 GB model: Fine consumption on standby, read values "ok" but high on write - with the same high bandwidth from approx. 1 Watts to 3.3 Watts.

Another two Patriot Burst 240 did also show the same results as the first Patriot Burst 240 measurement.

And the Kingston A400 960 was the first "1 TB class" SSD I measured. It did show the same great values like the 480 model did.

In addition to even more SSDs I made also the first measurement of an M.2 SSD (SATA, of course). Values were the same as for 2.5" SSD.

Apacer AS340 240 GB

240 GB means actually 468862128 sectors.

  • Idle 0.6 W
  • Read 0.76 W
  • Write 1.25 W, max 3.3 W
  • Read all sectors: 10m15.074s (372 MiB/s)
  • Write all sectors: 50m43.854s (75 MiB/s)

Method

Measuring environment is explained in power measuring ADATA SU800. The calculation of speed as logged in latest measurements was simply done by taking the time for reading and writing the whole SSD in relation to its size.
