• Drive 80 is a high-quality 250GB Samsung 860 EVO SSD. Look at the five regional performance measurements shown. Every one of them is exactly 274.1 megabytes/second, plus or minus zero! This is at least four decimal digits of benchmark accuracy.
  
• Drive 81, the SanDisk X300 256GB MSATA, is almost as stable. It is slower and its performance is a bit less rock solid, but even so, each of the five regions is either 182.5 or 182.6. So we're measuring +/- 0.5 accuracy.
  
• But look at drive 82! Something is very wrong at the front of this drive. It's also a 256GB SATA SSD, but it's an off-brand “addlink” drive removed from a reconditioned Dell laptop. This drive reveals what most users of the benchmark have seen from their own highly used SSDs. The four regions at 25%, 50%, 75% and 100% are measuring 174.7 to 175.0, so still very stable. But the front of the drive is measuring only 46.2 mb/sec! When you watch this benchmark run (see the video below) you will see the progress bar stall while the SSD struggles to read some regions that are clearly having serious trouble. It ends up succeeding, but something is very wrong.
  
• Drives 83 and 84 are old “spinners” – Maxtor spinning hard drives. The benchmark reveals that hard drives are faster at their front and show successively slower performance as we move to the end of the drive. This is due to the inner tracks having a smaller circumference and therefore storing fewer bits.
  
• The other remarkably interesting thing to observe is the 25% region of the last drive, it's a brand new, never used, 2TB Seagate Barracuda that was taken out of its factory sealed bag and plugged in for the first time for this benchmark. During the benchmark, you can see the progress bar hiccup in the 25% region. Something is wrong there, and this brand new drive has never been used!
