The test system used in this review was an HP 8200 Elite. The computer came equipped with an Intel Core i5-2400 CPU, 4GB of DDR3 1333MHz memory, Seagate Barracuda 7200.12 ST3250312AS 250GB SATA 6 Gb/s hard drive, NVIDIA Quadro FX580 512MB PCIe graphics card and an Intel 82579-LM gigabit network card. For the operating system, I installed a fresh copy of Windows 8.1 Enterprise.
To test the performance of Crucial's 500GB BX100, I ran a series of benchmarks using CrystalDiskMark 3.0.1, HD Tach RW 3.0.4.0, ATTO Disk Benchmark 2.46, AS SSD, HD Tune Pro 5.00, Anvil's Storage Utilities and Iometer. For comparison, I've also included test results from the Samsung 850 EVO M.2, Samsung 850 EVO mSATA, AMD Radeon R7, Silicon Power Slim S80, Samsung SSD 850 EVO, OCZ ARC 100, SanDisk Ultra II, Crucial MX100, SanDisk Extreme Pro, Samsung SSD 850 PRO, Plextor PX-256M6S, Toshiba Q Series Pro, Plextor PX-256M6M, Samsung SSD 840 EVO mSATA, OCZ Vector 150, OCZ Vertex 450, Silicon Power Slim S55, Samsung SSD 840 EVO, Seagate 600 SSD, SanDisk Extreme II, Plextor PX-256M5M, OCZ Vector, Plextor PX-256M5Pro Xtreme, Samsung SSD 840 Pro and Samsung SSD 840.
As I mentioned earlier, the BX100 is based on Silicon Motion's SM2246EN controller chip. Looking at the screenshot above, you can see that it performs equally well with both incompressible (0%) and compressible (100%) data.
CrystalDiskMark 3.0.3:
First, I ran a few quick tests using CrystalDiskMark. This benchmark tool measures the performance of a storage device by testing its sequential read and write speeds as well as its random read and write speeds using blocks 512K and 4K in size.

 Silicon Power S80 480GB |
According to Crucial, the 500GB BX100 is capable of reading at 535MB/s and writing at 450MB/s when connected to a SATA 6 Gb/s port. While the drive performed well, it came up a bit short of these numbers in CrystalDiskMark's sequential read and write speed tests.

 Silicon Power S80 480GB - All 0x00, 0Fill |
The BX100 performed equally well when using highly compressible 0x00 (0 Fill) data. This time around, the drive was able to read at 518.0 MB/s and write at 432.6 MB/s.
HD Tach RW 3.0.4.0:
Next, I used HD Tach to test the BX100's read, write and burst speeds as well as its seek times and CPU usage.
Looking at the screenshot above, you can see that the BX100 had average read and write speeds of 401.2 MB/s and 327.0 MB/s respectively, as well as a burst speed of 413.3 MB/s.
ATTO Disk Benchmark 2.46:
I also used ATTO Disk Benchmark to test the BX100's sequential read and write speeds. The tests are run using blocks ranging in size from 0.5KB to 8192KB and the total length set to 256MB.

When tested with ATTO, the BX100's read speeds topped out at about 561 MB/s and its write speeds at 465 MB/s.
