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 7 Enterprise.
To test the performance of AMD's 240GB Radeon R7 SSD, I ran a series of benchmarks using CrystalDiskMark 3.0.3, HD Tach RW 3.0.4.0, ATTO Disk Benchmark 2.46, AS SSD, HD Tune Pro 4.61, Anvil's Storage Utilities and Iometer. For comparison, I've also included test results from the 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.
Like OCZ's Vector 150 SSD, the AMD Radeon R7 SSD is based on the Indilinx Barefoot 3 M00 controller platform. Looking at the screenshot above, you can see that, unlike SandForce controllers, 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.
 AMD Radeon R7 240GB |
 Samsung SSD 850 PRO 256GB |
According to AMD, the 240GB Radeon R7 is capable of reading at 550 MB/s and writing at 530 MB/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.
 AMD Radeon R7 240GB - All 0x00, 0Fill |
The Radeon R7 performed equally well when using highly compressible 0x00 (0 Fill) data. This time around, the drive was able to read at 469.2 MB/s and write at 485.5 MB/s.
HD Tach RW 3.0.4.0:
Next, I used HD Tach to test the Radeon R7's read, write and burst speeds as well as its seek times and CPU usage.
AMD Radeon R7 240GB
Looking at the screenshot above, you can see that the Radeon R7 had average read and write speeds of 300.8 MB/s and 305.6 MB/s respectively, as well as a burst speed of 338.7 MB/s.
ATTO Disk Benchmark 2.46:
I also used ATTO Disk Benchmark to test the Radeon R7'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.
 AMD Radeon R7 240GB |
 Samsung SSD 850 PRO 256GB |
When tested with ATTO, the Radeon R7's read speeds topped out at about 557 MB/s and its write speeds at 532 MB/s.
