On Ubuntu, read speed was acceptable (200 MB/s+), but write speed dropped to around 80 MB/s.</p> <p>The fix was to adjust mount options in <code>/etc/fstab</code>.</p> <div class="highlight"><div class="chroma"> <table class="lntable"><tr><td class="lntd"> <pre tabindex="0" class="chroma"><code><span class="lnt">1 </span></code></pre></td> <td class="lntd"> <pre tabindex="0" class="chroma"><code class="language-fallback" data-lang="fallback"><span class="line"><span class="cl">/dev/disk/by-uuid/xxxxxxxxxx /mnt/WD_16T_01 ntfs-3g defaults,lazytime,uid=1000,dmask=007,fmask=117,big_writes,nofail,auto 0 0 </span></span></code></pre></td></tr></table> </div> </div><p>After this change, read/write speed returned to around 250 MB/s+.</p>
