SATA Testing Products

Program Description Devices Tested Current Version
AHCCMDT AHCCMDT is a write/read with compare test for Serial ATA devices. AHCCMDT also randomly issues most other ATA commands including power managment and SATA Partial and Slumber. AHCCMDT supports write/read command sector counts of 1 to 65536 and logical sector sizes from 512 to 32768 bytes.

The full version of this DOS program is FREE.

AHCDEMO AHCDEMO is able to execute any ATA/ATAPI command, using the standard ATA/ATAPI command protocols, from keyboard input or script file input. Perform write/read tests with data compare using only a few simple commands. Script files support IF/ELSE logic, CALL/RETURN for subroutines, WHILE loops, built-in and user defined variables and much more. AHCDEMO supports most SATA specific features such as Partial/Slumber, COMRESET, and NCQ/FPDMA.

About Our Testing Products

System Requirements

NVMEQRWT, NVMETEST, AHCCMDT, AHCDEMO and AHCNCQT are DOS DPMI mode programs. ATACT and ATADEMO are DOS real mode programs. These are typically run from a DOS USB drive. We recommend FreeDos and using "Rufus" to install FreeDos on a USB drive.

Why DOS?

NOTE: Until recently DOS was the best choice for device testing as is described below. However, it has become very difficult to purchase new systems that support legacy BIOS that is required by FreeDOS. We recommend you consider the Linux(r) versions of NVMEQRWT and NVMETEST programs available from High Performance Storage.

We know that during testing there may be times when the test system must be re-booted many times. With DOS this is quick.

Under an OS like Windows or Linux it is not possible to issue some device commands or perform some testing activities. These programs running under DOS have virtually no restrictions on what can be tested.

When testing most engineers would rather not waste time using a mouse to click three or more times on GUI interface menus in order to perform some simple test set up or test procedure. These programs have user friendly keyboard interfaces and powerful scripting capabilities that don't require time wasting mouse clicking.

When using Windows or Linux it is nearly impossible to completely fill up the SATA NCQ command queue within a device due to the huge interrupt overhead in these OS's. Under DOS programs like AHCNCQT have no trouble queuing up 32 NCQ write/read commands within a SATA HDD or SSD.

Host Controllers Supported

NVME devices conforming to the NVM Express specifications are supported.

The ATA* and AHC* programs access the ATA controller and drive hardware directly. The AHC* programs require an AHCI host controller. The AHCI host controller specification is available at the Intel web site (www.intel.com).

The ATA* programs require ATA host controllers that use the traditional ATA programming interface are supported. See the T13 document INCITS 370-2004 (1510D): ATA Host Adapter Standards.

Software License

Our products have a worldwide license. The products may be used at any company site worldwide. There is no restriction of the number of systems (computers) that can be used to run the products.
