mSATA + HDD vs mSATA + SSHD

Hey,

I have a Dell Inspiron 15r Special Edition 7520 and I want to increase the speed of my system, so I thought of buying a new and faster hard drive and perhaps a mSATA. Unfortunately, my Laptop has only SATA II. But now I'm stuck and don't know what combination I should choose?


I looked up different possible parts:
64 GB mSATA - 90$
128 GB mSATA - 120$

750 GB 7200RPM SATA 3Gb/s 16 MB Cache HDD - 70$
750 GB 7200RPM SATA 6Gb/s 32 MB Cache SSHD - 120$


So the main questions are:
Should I get a mSATA in combination with an HHD or in combination with an SSHD? If I get the SSHD, should I get the smaller mSATA or not?
Does it even make a speed difference with the SSHD when I run the Operating System on the mSATA?

 

120 GB SSD for OS and all programs, HDD for files and folders

 

So the SSHD does not speed up the system in combination with the mSATA?

I have more than 128 GB of applications. In this case will it be worth to invest in the SSHD or better not?

 

A full on SSD will give you much better speed than a SSD/HDD Hybrid. I'm a little confused...do you want to change to a single SSD/HDD Hybrid hard drive? You mention mSATA, but are you sure your Inspiron has the connectors? Here is some info regarding your model. If you have the right daughterboard and mSATA connectors, you can add a SSD as your boot/programs drive, and keep whatever HDD you currently have for files. Just get a SSD large enough to fit all your programs with some extra space left over (SSDs don't like to be full past a certain percentage). Prices have coma way down...check out Newegg or Amazon.

If you're asking about upgrading your current HDD to a SSD/HDD Hybrid, it will be faster than a conventional HDD, but not as dramatic as a full SSD + HDD.

If you haven't seen it, you might find this post helpful.

 

Thanks for the answer. I'm sorry, that I wasn't clear enough.
In my laptop, there is a free mSATA slot. The hard drive Dell built in this computer is slow (5600rpm), so I want to replace it. This hard drive slot has SATA II.

So now, I'm wondering, what hardware I can put in my laptop to get the highest performance. I don't want to go over 300$ with the price and I need 30GB space for windows, 70GB for often used applications and 140GB for games and not this often used applications.

So my idea was to set a 128GB mSATA in this laptop for windows and often used applications and additional the SSHD for the other applications and personal files.
But now, I'm not sure if the SSHD is worth it in this combination or should I better just get a HDD?

 

You have more programs than I imagined. You might consider waiting just a bit as the new, larger SSD just coming on the market that will shake up pricing. Or, decide which programs you need to speed up the most, get an SSD for those, and pick up a SSD/HDD Hybrid for what's left over

 

Thanks a lot!
