ATTO provides a wide range of storage connectivity solutions to help customers' better store, manage and deliver their data. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.įor over 30 years, ATTO Technology has been developing and delivering storage connectivity and infrastructure solutions for data-intensive computing environments. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes.
The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. XstreamCORE Fibre Channel intelligent Bridges.XstreamCORE Ethernet intelligent Bridges.
SiliconDisk™ RAM-based Storage Appliance.I'm told that some HDDs increase performance when this happens because of the way their controller logic works but I think this mostly applies to SSDs not mechanical drives. This is faster than 4k because there's more data read/written with less movement of the head.Ĥk: The same as above but instead of reading/writing the test data in 512KB 'chunks' it reads/writes in 4KB chunks.ĤkQD32: The same as 4K but there are more requests for the data sent to the HDD controller. This is fastest because the head doesn't have to move about a lot as all the sectors are adjacent.ĥ12k: CDM read/writes to random sectors on the drive, but it reads/writes 512KB of data at a random point, then moves to the next random point.
That is to say it starts writing on a sector and then writes the next part on the adjacent sector and so on. Sequential: Crystal disk mark (CDM) reads/writes whatever file size you choose when you start the test sequentially. I'm going to take a stab at it, but i'm no expert so if anyone really knows please feel free to correct me.
