All SSD for 15-bs158sa?

[Iain_B]

Hi, I'm shortly getting a 1Tb M.2 SSD (with a 2.5-inch adapter).  I am currently using a 250Gb M.2 SSD with the 1Tb HDD.

I'm wondering whether to go completely SSD, and keep the current 250 Gb M.2 and exchange the HDD for the new 1Tb SSD (with adapter) - i.e. all SSD;

OR

exchange the current 250 Gb M.2 for the new 1Tb SSD, and use this as the working drive, keeping the 1Tb HDD for backup, overflow, etc.

Would there be a significant saving on battery by going all SSD (first option)?

Or would there be an insignificant difference with keeping the HDD (second option)?  I do have, and sometimes use, 'hdparm'. 

Thanks.

PS. I have also upgraded to 8 Gb RAM.

That is up to your decison and your budget. We all know SSD is much faster than mechanical HDD and saving a bit of power when moving data. People have been talking about DIM (Data In Memory) for ages but with very higher cost therefore up to this point some large organizations still rely on SSD (also called Flash cards on some).

• For the first option: you have very fast storage devices with minimum work required,
• For the second option: you have more storage space but you need a lot more works and NOT sure the 1TB M.2 SSD would work or not.

Just my 2 cents.

Good - that's confirmed what I was starting to think.  2Tb is probably over-kill.  So I shall remove the current 1Tb HDD and replace that with the 1Tb SSD.  As you say, that will give me an efficient system, plus a little extra battery power saved.  And I shall use the current 1Tb HDD as an external drive for backups, etc.

1.25Tb on board, all SSD, should be good. 

Thanks
