SSD or mSATA for OS install

[Gurvesh23]

Hi Everyone,
i just purchased a dell XPS 15 9530 i7 16 GB with Win 8.1 pro installed,
that has
1 TB 5400prm HDD and
32 GB mSATA SSD installed

i plan to swap out both for
1. Samsung 850 Pro 1 TB 2.5-Inch SATA III Internal SSD
2. Samsung 850 EVO 1 TB mSATA 2-Inch SSD

i thought of buying the 2 TB SSD, but ...

which SSD should i use to install the OS (win 8.1) which i will upgrade to Win 10.

which will give me better performance after installing Samsung Magician.

thanks for your help.

mSATA should be the same as the SATA drive. They are both using the SATA controller. If it was a M.2 Drive then I would definatly say the M.2 drive as os but in this care it doesn't matter.

Higher density SSD tend to have better performance. You don't have to ask, look at their specifications. BUT, moving to a SSD from HD, you have already left Earth and gone to Alpha Centuri, now you are asking Alpha Centuri 1 or Alpha Centuri 2? Me, I don't care! Do whatever because of convenience, other factors blah-blah, either one is fast enough for whatever you want to do.

hahaha Alpha Centuri 1 would be the Samsung 950 NVMe SSD where as Alpha 2 would be like the Intel 750 lol

The thing is Most 250 GB + SSD's usually have the same read speed (500-550) and vary on write but as far as any of the samsung SSD's goes whether it be mSATA or SATA or even some of the M.2 SSD's most are the same of around 550 read and 520 write even on the 2Tb model. So it all depends. Do you want two different drives or just one big one?

it is like 700 USD for the two drives or 750 for a single 2TB. The ONLY thing that will be different is 2 vs 1. the specs are the same amongst all 3 of them.
