这是怎么回事这些写入速度？
纵向电场提高了写入速度及擦除速度。
The longitudinal component of the electric field increase the write speed and provdies erasure.
选择一个写入速度。
这意味着虽然它的读取速度远远快于标准HDD，但是写入速度则没有变化。
This means that while the read speed is much faster than a standard HDD, the write speed is about the same.
这在理论上应该增加的读取和写入速度的硬盘驱动器在所有情况下。
This theoretically should increase the read and write speeds of the hard drive in all scenarios.
选择一个写入速度。高的速度耗时少，但是如果产生问题，请选择一个较低的速度。
Select a write speed. Higher speeds take less time, but if they cause errors, select a lower speed.
在这种情况下，写入以磁盘速度进行，这很糟糕。
在这种情况下，写入过程以内存速度而不是磁盘速度进行，这是好的方面。
In this case, your writing process continues at memory speed, not disk speed, which is good.
正如上文讨论的一样，使用写入后缓存，事务在数据写入缓存时完成，这样速度更快。
As discussed earlier, with a write-behind cache, the transaction completes when the data is written to the cache, which is fast.
因此，write - behind缓存在访问所有写入数据以及所有缓存命中读取时都能提供内存速度，而且还有一些其他好处，我们将在下文介绍。
Thus, a write-behind cache gives you memory speed for accessing data on all writes, and for all cache-hit reads, and has other benefits that you will see later.
速度是MongoDB的另外一个优势，主要是由于它处理写入的方式：它们存储在内存中，然后通过后台线程写入磁盘。
Speed is another advantage of MongoDB, mainly due to how it handles writes: they are stored in memory and later, via a background thread, written to disk.
现在，如果告诉您程序将支持300万并发用户，必须以极高的速度写入，而且必须支持Nepali语言，您的评估是否会发生变化？
Now, if I told you that the program will support 3 million simultaneous users, must be written on the summit of Mt. Everest, and will have to support the Nepali language, does your estimate change?
研究者还在解决光盘能以多快的速度来写入的问题，并且说商业生产至少要等到五年以后。
The researchers are still working out the speed at which the discs can be written on, and say that commercial production is at least five years off.
持续地对磁盘进行写入操作可能会极大地降低程序的性能，导致其运行速度缓慢。
Continuous writing to a disk can largely degrade the performance of a program, causing it to run slowly.
持久化的消息则会把消息写入磁盘，即便系统发生故障也可找回消息，但相应的处理速度较慢。
Persistent messages are written to disk and are therefore recoverable in the event of a system failure, but are correspondingly slow.
WDS25硬盘与发烧级别的VelociRaptor产品有几分类似，不过前者的读写速度更快，其读取/写入寻道时间分别只有3.6ms和4.2ms。
Superficially, the WD S25 appears similarly to the VelociRaptor, but it has much faster read and write seek times at 3.6 ms and 4.2 ms respectively.
speed：执行测试以便查看数据以多快的速度读取并写入数据库。
Speed: Perform tests to see how fast data can be read and written to the database.
如果客户端在没有进行任何缓存的情况下直接写入远程文件，那么网络速度和网络拥堵会影响吞吐量。
If a client writes to a remote file directly without any client side buffering, the network speed and the congestion in the network impacts throughput considerably.
把对文件的修改汇成日志条目顺序地写入磁盘，既加速了写文件的速度，又加速了崩溃恢复的速度。
A log structured file system writes all modifications to disk sequentially in a log like structure, thereby speeding up both file writing and crash recovery.
一旦写入总线时钟初始化程序，在继续工程其它部分之前，也许想检验总线是否以期望的速度运行。
Once you write the bus-clock-initialization routine, you may want to verify that the bus is running at the speed you intend before moving on to the rest of the project.
通过对硬盘主轴马达的反电动势与马达转速之间关系的分析，提出一种利用马达的反电动势信号跟踪马达转动速度变化，产生系统伺服写入时钟信号的方法。
By analyzing relation between BEMF of the hard disk spindle motor and the rotate speed. This paper presents a new method of following the motor rotate speed by PLL to lock BEMF.
