XPS One 2720: Upgrade to SSD and keep existing 1TB HDD?

Hi There,

I have a Dell XPS One 2720, which currently has a 1TB HDD (the standard that came with the unit - Seagate ST1000DM003-1CH162) SATA-III 6.0Gb/s.

I am keen to add a SSD to boot from to increase boot speed.

I have a couple quite a few questions.

1. Is it possible to add a new SSD and also retain the existing HDD (for additional storage).

2. If so, is it correct that I need an mSATA (rather than SATA III) SSD?

3. Also, is it correct that for some reason there is a limit of 256GB for installing an mSATA SSD?

4. Finally, does it matter if the mSATA SSD is 6GB/s or 3GB/s in terms of compatibility?

Would appreciate any help and advice as I am pretty new to this, and learning as I go along.

(NB I did search the forums, and found answers which appears to suggest this is possible, but just want to ensure I am buying the right thing before I shell out the cold hard cash(!) - and would also like bigger than 256GB SSD if possible. 

If it helps I am looking at this, if someone can advise if it is compatible?

Many thanks in advance

Thank you for reaching out to Dell Community Forum.

The maximum hard drives supported on XPS 2720 is as follows:

one 3.5-inch hard drive - 1TB, 2TB, 3TB and 4TB with 7200 rpm

one mSATA SSD -  256 GB with 3 Gb/s

You can retain the SATA hard drive along with the mSATA SSD drive.

RE: XPS One 2720: Upgrade to SSD and keep existing 1TB HDD?

I am trying to upgrade my SAMSUNG PM830 32GB msata drive that came w/my XPS 2720. (It will become the boot drive like op above.) I would like the biggest drive I can get. The advice you gave above indicates "one mSATA SSD -  256 GB with 3 Gb/s." However the specs from my original msata drive indicates that Host Interface "SATA Gen 3.0 – 6Gb/s." Does this mean I can get an SSD drive that has those specs and can I get something bigger than 256gb? (Dell motherboard Motherboard Dell Inc. 05R2TK) 

I'm not that computer literate. Not sure if I gave enough info to reply. Thanks.

It's better to ask a new question instead of continuing an old thread. You are limited to those upgrades. You cannot replace the 32 gb m-ssd cache drive with a ssd boot drive. Keep what you have now until you can replace the computer. All in ones are not suitable for major upgrading. 

See your manual--

I upgraded the original mSATA SSD installed on the motherboard with a 1TB Samsung

Samsung 840 EVO MZ-MTE1T0BW 1TB mSATA Internal SSD Single Unit Version
Sold by: DiscTech LLC

I worked fine.  But then I upgraded the original 2TB hard drive with a 4TB 

Seagate 4TB Barracuda Sata 6GB/s 128MB Cache 2.5-Inch 15mm Internal Bare/OEM Hard Drive (ST4000LM024)

System works fine but for some reason the BIOS recognized the 4TB hard drive including manufacturer etc, but when I reinstalled Windows I only get 2TB in File Explorer.
