Avoid the problems of unreliable BIOS and OS device driver stacks - use NVMEQRWT, NVMETEST, AHCCMDT, AHCDEMO, AHCNCQT, ATACT or ATADEMO and perform some real testing of your NVME or ATA/ATAPI products.
Try out the free demo/eval versions of NVMEQRWT, NVMETEST, AHCCMDT, AHCDEMO, AHCNCQT, ATACT and ATADEMO!
Read our { EXECUTIVE SUMMARY } and learn why you should be using our products to test your NVME, ATA (HDD or SSD) or ATAPI device.
ATA-ATAPI.COM develops and sells test software for NVME, ATA and ATAPI devices. ATA-ATAPI.COM DOES NOT manufacture or sell hardware of any kind. ATA-ATAPI.COM DOES NOT provide technical support for any hardware products. ATA-ATAPI.COM DOES NOT provide firmware or OS driver updates for any hardware products.| Program | Description | Devices Tested | Current Version |
| NVMEQRWT | NVMEQRWT is a random and sequential read/write command test using up to 15 read/write queues
and up to 32 commands per queue.
VERSION 2A0 WAS SENT TO ALL CUSTOMERS IN MAY 2017. Go to the How To Order page. CLICK HERE for more information and free/demo download. |
An x86 PCI bus system with at least 1GB of memory, at least one NVME controller. | 2A0 May 2017 |
| NVMETEST | NVMETEST is able to execute all mandatory NVME commands
and Vendor Unique commands
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.
VERSION 2A1 WAS SENT TO ALL CUSTOMERS IN MAY 2017. Go to the How To Order page. CLICK HERE for more information and free/demo download. |
An x86 PCI bus system with at least 1GB of memory, at least one NVME controller. | 2A1 May 2017 |
| 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.
VERSION 3A1 WAS SENT TO ALL CUSTOMERS IN 2016. Go to the How To Order page. CLICK HERE for more information and free/demo version download. |
An x86 PCI bus system with at least 1GB of memory, at least one AHCI SATA host controller. Intel AHCI host controllers are recommended. | 3A1 March 2016 |
| 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.
VERSION 3A4 WAS SENT TO ALL CUSTOMERS IN MAY 2017. Go to the How To Order page. CLICK HERE for more information and free/demo download. |
An x86 PCI bus system with at least 1GB of memory, at least one AHCI SATA host controller. Intel AHCI host controllers are recommended. | 3A4 May 2017 |
| AHCNCQT | AHCNCQT is a write/read with compare test for Serial ATA NCQ (FPDMA) commands.
The goal of AHCNCQT is to maintain a full queue of 32 NCQ (FPDMA) commands
in a device. AHCNCQT supports write/read command sector counts of 1 to 65536 and
logical sector sizes from 512 to 32768 bytes.
VERSION 3A2 WAS SENT TO ALL CUSTOMERS IN MAY 2017. Go to the How To Order page. CLICK HERE for more information and free/demo download. |
An x86 PCI bus system with at least 1GB of memory, at least one AHCI SATA host controller that supports NCQ (FPDMA). Intel AHCI host controllers are recommended. | 3A2 May 2017 |
| Program | Description | Devices Tested | Current Version |
| ATACT | ATACT is a basic write/read with compare test. But ATACT
also uses most of the ATA commands, such as power management.
THE LAST UPDATE TO THIS PROGRAM WAS IN 2012. Note: If you are testing SATA then you really should be using AHCCMDT. Go to the How To Order page. CLICK HERE for more information and free/demo download. |
One ATA or two ATA or one ATA and one ATAPI, both devices must be on the same ATA channel, devices may be PATA or SATA, -or- one PCMCIA PC Card ATA or CompactFlash (CF). |
5A0 March 2012 |
| ATADEMO | ATADEMO 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.

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.
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.
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.
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.
There is no specific NVME driver. Because the NVME interface is so simple the NVME functions used by NVMEQRWT and NVMETEST are integrated directly into these program.

If you need help creating an AHCI driver send us an email with your question(s) and we will try to help you.
