CrystalDiskMark is a HDD benchmark utility for your hard drive that enables you to measure sequential and random read/write speeds.
Here are some key features of “CrystalDiskMark”:
· Sequential reads/writes
· Random 4KB/512KB reads/writes
The blistering read and write performance continues here. This test doesn’t show the drop in speeds with a used SSD. This is one of the reasons the synthetic tests do not represent a real world scenario and why we test with real world files later in this article. But compare the 4K read and write performance of a SSD to HDD. The read performance is almost 22 times faster while the write performance is nearly 4.5 times faster. This gain in performance in seen booting of Windows as a SSD will load the small sized files a lot faster than a HDD.
