text: user7427: Trying to download run data of Run accession SRR2155174. Here's the link: https://trace.ncbi.nlm.nih.gov/Traces/sra/?run=SRR2155174
  Please go to the link and go to the "Data Access" tab. Hereunder header "Name" you can find two links:
  https://sra-downloadb.be-md.ncbi.nlm.nih.gov/sos1/sra-pub-run-5/SRR2155174/SRR2155174.1
  https://sra-downloadb.st-va.ncbi.nlm.nih.gov/sos2/sra-pub-run-6/SRR2155174/SRR2155174.1
  Do these two links download the same data or they are for different purposes?
  Thanks
  
  user7439: It seems just like two different mirrors contains the same SRA archive. If you still doubt, you can download both (its have relatively small size) and compare their md5sum.
