SSD vs HDD

  Hello
  
  I am looking to add storage to my workstation, since I am running transient analyses with 300-400GB of data per run. My current specs are:
  
  Cpu: Intel Xeon CPU E5-1620 v3 " 3.50GHz
  RAM: 16GB DDR4 2133MHz
  Graphics: Geforce Quadro K620
  240 GB SSD
  Storage: 1TB 7200rpm HDD
  Windows 10 Pro
  
  At the moment the software writes all data directly to the 1TB drive. My question is will the replacement with a 3TB SSD be more beneficial compared to a 3TB HDD for saving and writing all data?
  
  Thanks in advance

  Hi Gate9er,
  
  If you are looking to improve solving time, you may get much more benefit from increasing your RAM.
  
  SSD is definitely better than HDD but is it worth the investment ? That's still open to discussion.
  
  I'm not exactly familiar with performance related, I will ask someone to chime in.
  
  Thanks,

  Hi Gate9er
  
  Are you keeping 3-400GB of data per run? I agree with Win - I'd look to put some of the money in RAM. I'd replace the current SSD with one big enough for all the current installed programs, one analysis, plus a buffer. So say 1TB SSD. Then the fastest 3-4 TB platter hard drive you can afford with the remaining money for storage of the solved models. Size/cost depending on how much of the solved models you want to save.
