ATACT - 一個隨機位置和隨機數據讀/寫測試ATA硬碟,但它也發出了其他"標準"ATA命令,包括電源管理命令。ATACT易於安裝和使用。該程式能夠測試一個或兩個ATA硬碟,並且可以運行很長一段時間。不同於大多數的錯誤,包括類型的信息,通常只使用ATA bus analyzer,但ATACT卻能夠提供更詳細的錯誤報告。
Note:如果你正在測試SATA設備,你真的應該使用AHCCMDT。
ATACT使用所有的ATA強制命令和一些可選的命令(如果設備支持)來測試,ATACT預計完全支持ATA-x和ATA/ATAPI-x設備標準,包括 大量數據轉換、改變為CHS幾何形狀和sectors per multiple block、啟用/禁用、讀/寫、緩存和具有未被破壞數據的不尋常命令列。
支援48位元的LBA命令,使在PIO和DMA模式下數據傳輸速度高達65536sectors。ATACT支援廣泛的PCI Bus Mastering ATA主機適配器,和所有的PCMCIA PC Card ATA I/O 和內存接口模式。
ATACT已被更新為可支援Serial ATA (SATA)設備。SATA似乎有很多的問題但ATACT似乎可以找到更多,這些問題出現超時錯誤、數據損壞錯誤等。如果你正在測試SATA ATA設備,你一定會需要STACT!
ATACT使用Hale Landis驅動低的ATADRVR標準ATA/ATAPI。ATACT是一個商業產品,你或你的公司必須購買一個Ccopy的程式。因為試用版的功能較少,僅適用於評估程式使用。
試用版限制了以下功能:
運行時間限制不得超過60分鐘
設備大小限制為4000000(4M)sectors
沒有電源管理命令被執行
任何設備錯誤中,有限的訊息顯示在日誌文件中
NOTE: ATACT是舊版的Parallel ATA (PATA)和CompactFlash (CF)測試應用程式。如果你是要測試Serial ATA (SATA)設備,你需要使用AHCCMDT。ATACT 第5A0版"可能"會是ATACT的最後一個更新版本。

I/O Inefficiencies that Rob Performance
There are 2 severe I/O inefficiencies that cause performance and reliability problems.
First, is caused by the behavior of the Windows file system. It will tend to break up writes into separate storage I/Os and send each I/O packet down to the storage layer separately and this causes I/O characteristics that are much smaller, more fractured, more random than they need to be.
Second is storage IO contention, also known as the I/O Blender Effect, which happens when you have multiple systems all sharing the same storage resource, such as multiple VMs all sending small, random I/Os down through the same hypervisor.
Your performance is penalized twice by these storage I/O inefficiencies causing systems to process workloads about 50% slower than they should.
DymaxIO dynamically accelerates data for maximum I/O performance. By solving I/O inefficiencies at the source, DymaxIO
Proactive and Efficient Server Performance Optimization
DymaxIO contains thin file system drivers, that installs (no reboot required) on Windows VMs or physical servers and performs optimizations inline automatically while running transparently in the background with near-zero overhead to the server. What little CPU cycles are needed to run at lowest priority so as not to interfere with server operations in the event that CPU cycles are needed by other applications or processes.
DymaxIO contains a suite of patented technologies that optimize the Windows Storage I/O subsystem so that applications can get to and from the storage layer much faster and process a lot more data.
Some organizations may react to performance challenges by throwing expensive new hardware at the problem. Overbuying and overprovisioning for more IOPS or data throughput might mask the underlying problem for a while, but it does not solve the root cause of performance issues. The quickest, most inexpensive, and least disruptive approach to more performance is simply installing DymaxIO fast data software on all of your Windows systems and watching performance problems disappear.

The audio latency problem
Windows is not a real-time operating system. All requests to the operating system are delivered on a best effort basis. There are no guarantees whatsoever that requests are delivered within a certain time frame, which are the characteristics of a real-time operating system. That is not a problem for most devices and tasks but this is bad news for audio applications (which are considered soft real-time) because they need to deliver data to the subsystem and the hardware in buffers several times per second. If one or more buffers miss their deadlines and are not delivered in time it has audible consequences which are recognized as dropouts, clicks and pops.
About DPCs and ISRs
The Windows thread dispatcher (also known as scheduler) which is part of the kernel executes threads based on a priority scheme. Threads with higher priority will be given a longer execution time (also known as quantum or time slice) than threads with a lower priority. However the kernel also knows other types of units of execution known as interrupt service routines (ISRs). Devices connected to the system may interrupt on a connected CPU and cause their interrupt service routines to execute. An interrupt can occur on the same processor that an audio program is running on. Any thread that was running on the processor on which an interrupt occurred will be temporarily halted regardless of its priority. The interrupt service routine (ISR) is executed and may schedule a DPC (Deferred Procedure Call) to offload an amount of work. The DPC will most likely run immediately on the same processor which means the audio application will halt until both the ISR and the DPC routines have finished execution. That is because ISRs and DPCs run at elevated IRQL which means they cannot become preempted by the thread dispatcher (scheduler). Therefore to guarantee responsiveness of the system, ISR and DPC routines should execute as fast as possible. Guidelines say that they should not spend more than 100 µs of execution time however this is often not reached due to hardware factors beyond the control of the driver developer. If execution time gets too high, the audio program may be unable to deliver audio buffers to the hardware in a timely manner.
About hard pagefaults
Windows uses a concept of virtual memory which relies on the page translation system provided by the CPU. Whenever a memory address is requested which is not available in physical memory (not resident), an INT 14 will occur. The OS provided INT 14 handler will decide how to proceed next. If the page in which the address...
