Marvell 88SS9174 Performance
The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.34 version of the program, but the benchmark is still limited to non-linear samples up to 256MB. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.
Our basic bandwidth speed tests begin with the Crucial RealSSD-C300 connected to the integrated HighPoint Rocket 620LF PCI-Express SATA-III 6.0 Gbps adapter, as the ATTO Disk Benchmark tools performs file transfers ranging from 0.5 KB to 8192 KB. The 256GB CTFDDAC256MAG-1G1 model reveals an impressive 383 MBps maximum read speed that plateaus from 256-8192 KB file chunks, while the 227 MBps peak write bandwidth plateaus from 32-8192 KB. These results surpass the stated 355/215 MBps maximum given by Micron.
HD Tune is a low-level test that will not operate on a drive which contains a partition, so Benchmark Reviews uses DISKPART to prepare hardware and remove any partitions before conducting these tests. Random Access tests are divided into 512b, 4KB, 64KB, 1MB and random size test files sizes. The Random Access test measures the performance of random read or write operations. The amount of data which will be read varies from 512 bytes to 1 MB. Performance is reported in operations per second (IOPS), average access time, and average speed. Because it is our intent to compare one product against another, Benchmark Reviews has focused on random transfer size IOPS performance.
The Crucial RealSSD-C300's 4KB random IOPS performance in HD-Tune measured 7941 for read IO, and 2451 for write. In comparison, the 4KB read IOPS was ahead of Corsair's X256 SSD which scored 7444, and the Vertex Turbo's 7272. Alternatively, both the Vertex Turbo (17358 4KB write IOPS) and Corsair X256 (16244) SSDs are well ahead of the CTFDDAC256MAG-1G1 in terms of IOPS write-to performance.
In the tests below, Benchmark Reviews utilizes the HD TachRW tool to compare the fastest collection of desktop hard drives and competing SSD's we can get our hands on. Using the Intel ICH10R SATA controller on the Gigabyte GA-EX58-UD4P, HD Tach was used to benchmark the test SSD five times with the best results displayed below. It's important to note that HD Tach's Burst Speed result should be ignored for Solid State Drives due to the cache methods inherent to each memory controller architecture. There are times where this number will be extremely high, which is a result of the optimized cache used for SSD's.
The important numbers used for comparison are the sustained read and write bandwidth speeds, which indicate an approximate performance level of the product. Our featured test item, the Crucial RealSSD-C300 model CTFDDAC256MAG-1G1 MLC SSD, performed at an average 319.4 MBps best sustained average read speed and a best average sustained write bandwidth of 213.9 MBps in HD-Tach. Read speeds peak at 330 MBps, while writes peaked at 225 MBps.
The Crucial RealSSD-C300 offered up to 383/227 MBps read and writes speeds in ATTO Disk Benchmark trailed by 363/226 MBps in Crystal DiskMark, while Everest reported a 332/215 MBps linear bandwidth speed. Input/Output performance was modest in Iometer and HD-Tune, indicating that the CTFDDAC256MAG-1G1 model would perform extremely well for enthusiast consumers but not offer the high operational functionality needed in the Enterprise server sector.
Benchmark Reviews has tested the Crucial RealSSD-C300 6.0-Gbps SSD, and the performance results were leading-edge. Based on our benchmark tests of this SATA-III Marvell-based storage product, the CTFDDAC256MAG-1G1 model delivers a noteworthy 0.16 ms response time which assures a nearly-instant reactions when called upon, and showed absolutely no sign of data-write stuttering during our tests (although Everest linear write tests shows some moments where the buffer transitioned). Based on the high-performance Marvell 88SS9174-BJP2 SSD processor, the Crucial RealSSD-C300 delivers native TRIM garbage collection and Sanitary Erase support with impressive transfer speeds deserving of the SATA 6Gb/s interface.
Benchmark Reviews tested the 256GB Crucial RealSSD-C300 (CTFDDAC256MAG-1G1 model) for this article, which is sold by Crucial for $799 while NewEgg lists for $759. Alternatively, there's a 128GB version of the RealSSD-C300 available (CTFDDAC128MAG-1G1) directly from Crucial for $499 of from NewEgg for $479.
