Testbed and Methods
The Samsung 470 series being not the latest of SSD generations, we decided to use a rather old testbed for it. Replacing an HDD with an SSD in an old computer can make the latter much more responsive.
We used the following testing utilities:
- IOMeter 2003.02.15
- FC-Test 1.0
- PCMark Vantage
The testbed was configured as follows:
- ASUSTeK P5WDG2 WS Pro mainboard
- Intel Pentium 4 620 CPU
- IBM DTLA-307015 (15 GB) as a system hard disk
- Radeon X600 graphics card
- 2 GB DDR2-800 SDRAM
- Microsoft Windows 7 Ultimate
The following SSDs were benchmarked in this test session:
- OCZ Performance Agility 2 240GB SATA300, firmware 1.25
- OCZ Vertex 2 OCZSSD2-2VTX200G 200GB SATA300, firmware 1.28
- Intel X25-M SSDSA2M120G2GC 120GB SATA300, firmware 2CV102HD
- Samsung SSD 470 series MZ5PA256HMDR-01000 256GB SATA300, firmware AXM0601Q
We installed the OS’s generic drivers for the SSDs. We formatted the drives as one NTFS partition with the default cluster size. For FC-Test two 32GB partitions were created on the drives and formatted in NTFS with the default cluster size, too. The drives were connected to the mainboard’s SATA port and worked in AHCI mode.
IOMeter is sending a stream of read and write requests with a request queue depth of 4. The size of the requested data block is changed each minute so that we could see the dependence of the drive’s sequential read/write speed on the size of the processed data block. This test is indicative of the maximum speed the drive can deliver.
Sequential reading is a strong point of the Samsung 470 drive. Its seems to be good not only as a system disk for reading data from but also as an all-purpose disk for any applications.
