HD Tach RW Benchmark Results
EDITORS NOTE: Please read Solid State Drive (SSD) Benchmark Performance Testing to understand how the benchmarks used in this article should be interpreted.
HD Tach is a software program for Microsoft Windows that tests the sequential read, random access and interface burst speeds of the attached storage device. For the record. every single product tested was brand new and never used. HD Tach allows write-bandwidth tests only if no partition is present. Additionally, each and every product was tested five times with the highest and lowest results removed before having the average result displayed here. The graphical user interface (GUI) of the Windows-based benchmark tool HD Tach is very convenient. and allows the test product to be compared against others collected on your system or those registered into the Simpli Software database.
In the tests below, Benchmark Reviews utilizes the HD TachRW tool to compare the fastest collection of desktop drives and competing SSD's we can get our hands on. Using the JMB363 SATA controller on the Gigabyte GA-X48T-DQ6, HD Tach recorded a 127.8 MBps burst speed for the SATA-II Silicon Power SSD, which for Solid State Drives should not be a deciding factor due to the cache methods inherent to each memory controller architecture. There are times where this number will be extremely high, such as the 260+ MBps we recorded while testing the OCZ OCZSSD2-1S32G. The important numbers are the average read and write bandwidth speeds, which indicate the true performance level of the product. Our featured test item, the Silicon Power 32GB SLC SATA-II SSD SP032GBSSD750S25, performed at 120.6 MBps sustained read bandwidth and an impressive 87.9 MBps sustained write bandwidth.
The chart below illustrates the collected benchmark results for HD Tach RW on the JMicron SATA controller, with the read and write bandwidth results added together to determine placement. Without question, the MemoRight GT MR25.2-064S SSD enjoys a substantial lead over the entire field of storage products with an impressive 117.9 MBps read-from and 122.8 MBps write-to bandwidth speed (240.7 MBps collectively). In second place with a collective total of 233.0 MBps is the Mtron Pro 7500, which produced results only 3% behind the leader. After these two products, the collective bandwidth falls off.
Unlike the System Speed Test benchmarks that placed the OCZ CORE SSD near the lower portion of our charts, HD Tach positions the SATA-II Silicon Power SLC SSD in fourth place within our test results. Even still, the 120.6 read and 87.9 MBps write bandwidth only trails behind the top-position leader by only 15%.
Our chart indicates that the midrange portion begins with OCZ's SATA-II SSD, which trails a decent distance behind with 94.3 MBps read and 85.9 MBps write, followed by the Seagate 7200.11 HDD with 88.8 and 78.8 MBps respectively. Mtron's Pro 7000 and Samsung's SATA-II SSD (not charted) are trailed by the Crucial SATA-II SSD and Mtron MOBI 3000, which both feature great read speed paired with less-desirable write bandwidth.
At the bottom half of our chart is the Western Digital Raptor 74GB 3.5" WD740ADFD 10,000 RPM SATA Hard Disk Drive. Sustained speeds seem to taper out after the initial burst for this drive, which by no means is a slouch - but just not as high-bandwidth as the others in our test group. The Super Talent MasterDrive MX SATA-II SSD seems to also suffer from a very poor write bandwidth matched against very good read performance. Finally, the Silicon Power 64GB SATA SSD SP064GBSSD25SV10 offers the second worst performance out of an SSD we've ever seen, only to be under-performed by OCZ's original SSD product which arrived to market almost a year ago.
