To keep, or not MMPEK

[Harry Bloomfield]

I'm in the midst of sorting out my HP laptop, which died some while ago, due to HDD failure, plus some other issue, which resolved itself..

Original HDD was a WD Blue 1Tb + a M10 MEMPEK1J016GAH 16Gb SDD stick, it was reasonably fast. I got it going with an old slow Toshiba 1Gb, but I am now going to replace the Tosh, with an SDD sata III, 6Gb/s drive. The question is, should I keep the MEMPEK, or not, for best speed?

The SATA SSD is still going to be slower. At 6Gb/s, it's about 600MB/s max transfer speed, if the laptop and SSD can sustain that.
The Optane drive has a maximum transfer speed of 800MB/s.
Its use as a cache may not make a big difference, but it probably won't cause any harm. And it's not much use anywhere else, as Intel has killed off Optane memory.
You can always try first without it?
