Lenovo Ideapad z470 Review - Part 4: hard drive benchmarks

< Back to part 3: 3d benchmarks

OK welcome to part 3 of my review. Hard drive benchmarks. I'm limiting it to synthetic benchmarks. We are comparing my desktop's hard drive, a WDC black 1 terabyte model WDC WD1002FAEX-00Y9A0 with the laptop's 750 gig WDC drive model WDC WD7500BPVT-24HXZT1.

For all the results, the first result or picture will be the desktop's hard drive, followed by the laptop.



1. Passmark performance test 7 build 1025 (Disk test only, copied from part 2 of the review)

  • desktop: disk = 735.6
  • laptop : disk = 623.5


2. Atto disk benchmark v 2.46








3. Crystal disk mark 64 bit v 3.0.1

  Test : 1000 MB [C: 76.3% (186.3/244.0 GB)] (x5) 
  4. HDTune pro v5 trial



Well pretty much all the tests show the desktop's HD to be faster, but they are quite close. Perfectly acceptable performance for a 2.5 vs 3.5 hard drive.

OK that's it. I'm planning a part 5: wifi file transfer benchmarks
