Which laptop should I choose? (+ what is the difference between SSD and Mobility SSD?)

[Pershing]

Hey guys!

I'm looking to buy one of the new 2015 xps 13 models. There are two I am looking at.

One has:...i7-5600u and 256GB SSD.
The other: i7-5500u and 512GB MOBILITY SSD

All other specs are the same apart from the wireless but.. will get to that later.

So, my question is - what is the difference between the SSDs apart from the size? What is a mobility SSD? I've looked around online but can't seem to find anything. Is it simply that the 256GB is a 2.5" standard SSD and the mobility SSD is mSata? I thought mSata stood for mini sata though.

And, which laptop should I go for? The slightly faster cpu is always nice to have but the other one is double the storage space. However, if the faster cpus ssd is a standard 2.5" then I have a spare 512GB 2.5" ssd here anyway so can upgrade it as soon as it arrives in which case that would be better (and £50 cheaper!)

The other difference as I said is the wifi. The i7-5600u model comes with 'Intel(R) Dual Band Wireless-AC 7265 2x2 + Bluetooth 4.0' and the i7-5500u comes with 'DW 1560 + BT4.0 [802.11ac + Bluetooth 4.0, Dual Band 2.4&5 GHz, 2x2]' - and according to the dell site, the i7-5600us wireless connection is the 'better' one since its highlighted in the compare screen.

Thanks !

SSD is SSD. I don't know why the word "mobility" was used.

The i7-5600u is only 200MHz faster than the i7-5500u. Unless you are doing something that is really CPU intensive you will not really notice the difference. I would simply choose the i7-5500u and the 512GB SSD version. The Dell XPS 13 ultrabooks uses mSATA format SSDs.

There are currently 3 different formats for SSD drives. None are compatible with each other since the connections are different.

#1 - SATA III - This is a standard 2.5" form factor that is also used by laptop hard drives.

#2 - mSATA - This is mini-SATA and it is basically a circuit board with SSD RAM modules and a controller. It is smaller than the SATA III form factor with a different connector. Ideal for ultrabooks where size and weight matters. Actually, this seems to a SATA III format SSD without the case which allows it to fit inside a smaller space. The holes allows you to screw the mSATA into place so that it does not move.

#3 - M.2 - This is the newest form factor for SSDs and is even smaller than mSATA SSDs; much harder to buy as well since not many etailer carries this format yet.

Hello everyone,

I'm also thinking about buying the new XPS 13 and I'm having the same question as well whether to buy the 256GB or the 512GB version.


1) So there's no difference e.g. according to speed performance between these two SSDs?

2) Is there any difference between Dells own wifi chip used in the 512GB version (Dell Wireless 1560 + Bluetooth 4.0 (802.11ac, 2x2, Dualband, 2,4 GHz and 5 GHz, Bluetooth 4.0) and Intel's AC 7265 in the 256GB one? Don't want to have lower wifi speed in order to have more ssd space...


Thanks in advance! )
