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.
In the tests below, Benchmark Reviews utilizes the HD TachRW tool to compare the Silicon Power 64GB SATA Solid State Drive against the fastest collection of desktop drives and competing SSD's we can get our hands on.
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.
HD Tach recorded a 136.0 MBps burst speed for the OCZSSD2-1C64G, which for Solid State Drives should be ignored due to the memory controller architecture. There are times where this number will be extremely high, such as the 260+ MBps we recorded while testing the OCZ SATA-II 32GB 2.5" SSD 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 OCZ Core Series SATA II SSD, performed at 118.7 MBps sustained read bandwidth and 73.8 MBps sustained write bandwidth.
The chart below illustrates the collected benchmark results for HD Tach RW, 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 and 122.8 MBps write bandwidth speed. Unlike the System Speed Test benchmarks that placed the OCZ CORE SSD near the lower portion of our charts, HD Tach positions the OCZSSD2-1C64G second only to a $2000 SSD.
The OCZ SATA-II 64GB 2.5" SSD OCZSSD2-1S64G 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 are trailed by the Crucial SATA-II SSD and Mtron MOBI 3000, which both feature great read speed paired with pathetic 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.
