    HI guys,

    I have to replace my prehistoric latitude d630 laptop from 2008, im trying to decide between a dell latitude or a lenovo thinkpad - They have same processor / spec etc.. except the following.

    The Dell has a normal SATA 500GB with 8GB DDR4 memory

    The Lenovo has a SSD 500GB with 8GB DDR3

    Obviously the DDR4 has a faster clock speed, but the SSD has a better read/write

    They both have i5 6th generation same clock speed, same graphics etc..

    The dell one is 200 quid more for the spec i need. Dell said they no longer let you configure the models for this and suggest i buy their one, then buy a SSD and swap them out myself.

    I will be using this mostly for visual studio development for web applications and just messing about on google etc..

    Can anyone help me decide please, i know some of the guys on here are excellent with this sorta stuff or suggest another like for like model maybe?

    here are the laptop profiles:

    It wont let me post the links..

    Thank you kindly,

    The SSD performance will be far far better than DDR4. Well, it will be far more noticeable. I would want the best spec possible, so I can see the draw of DDR4, but without an SSD I just wouldn't go for it.

    You will not be able to tell between DDR3 and DDR4. Performance difference between HDD and SSD - humongous.

    Definitely the SSD will have a bigger impact. I upgraded my SATA drive to SSD, and logon time went from +5 minutes to 22 seconds. Everything is so much faster since the SSD went in.

    Are you sure it's a 500GB SSD and not an SSHD? Still an improvement on a normal hard drive but not as fast as an SSD.

    In any case, if it's €200 more just for DDR4, forget it. You'd want to be doing serious crunching with your laptop around the clock to notice any difference.

    Good point, i just looked at it again and your right.
    it offers a choice of the following for the lenovo:

    SSHD 500GB5400 8GB Cache

    192GB Solid State Drive, SATA3

    the SSD is 22 EUR more. so its a case of working out my storage requirements, thanks for the advise guys you have been great help.

    I maintain a Y50 with one of those SSHDs, they're dire. Performance is all over the shop, a decent regular drive would be far better.
