12/11/2023 0 Comments Sequential take 5 firmwareThis is in contrast to the ATTO Benchmark used by LSI/ Sandforce and its partners when they market a given solid state drive. On the 4K 64 thread tests speeds were fairly similar with firmware v1.5 slightly edging out firmware v1.4 and nearly reaching 80K IOPS during writes (reads were just over 87K.) CrystalDiskMarkĬrystalDiskMark is another benchmark which gives non-compressible read/write numbers. 4K speeds saw reads slightly improve and writes slightly decrease. OCZ Vertex 4 v1.5 Firmware AS SSD BenchmarkĪS SSD saw sequential read speeds rise by about 13MB/s and sequential write speeds raise by 24MB/s. The result is perhaps one of the best workstation SSD benchmarks available today. AS SSD BenchmarkĪS SSD is a solid benchmark that does not write compressible data to drives. To this end, AS SSD benchmark, CrystalDiskMark, ATTO and HD Tune Pro all show different facets of performance. One should look at a few different tests to get an idea of how the drives perform in different scenarios. It is important, especially with SSDs not to take a single test result at face value. Corrected a corner case issue where the ‘Remaining Life’ SMART attribute could be reported incorrectly.Further improved compatibility with desktop and mobile ATA security features.Optimized idle garbage collection algorithms to extend the benefits of performance mode by enabling the feature across a greater percentage of the drive.Improved sequential file transfer performance for 128GB, 256GB and 512GB models.My how times have changed for solid state drive updates! OCZ Vertex 4 v1.5 I still remember burning CD-R media with a DOS image, a firmware update tool and a firmware package then hunting for the correct drive only after setting the controller and jumper correctly. OCZ has put some effort into making SSD firmware updates much easier than in the past. Also, installing the Intel RST 10.xx series drivers over the default Windows 7 drivers showed a nice performance gain so I do recommend it for solid state drive users on Intel chipsets. Power Supply: Supermicro 300w (included in the SC731i-300B)Īs with any modern SSD, set the controller to AHCI mode or RAID mode for best performance.Additional NICs: Intel Gigabit CT PCIe x1 network adapter.I am using a Sandy Bridge test bed here as the Cougar Point SATA 6.0gbps controller is perhaps the best 6.0gbps SATA controller on the market at the moment. Let’s look at some quick benchmarks below. The 4K low queue depth benchmarks seem to have been sacrificed for this speed enhancement though. As a quick spoiler, across benchmarks, there is an improvement with the new solid state drive firmware, although not as big as we saw with v1.3 to v1.4. Today we are looking at firmware v1.5 to see if there was a similar performance update. Keen readers will remember performance was increased significantly with firmware v1.4. The OCZ Vertex 4 line, including the Vertex 4 256GB recently received another firmware update.
