One problem for users who want to equip their old Mac with a third-party SSD (SSD) is that the OS X system does not turn on TRIM support for Third-party SSDs. TRIM is a system-level command that allows the operating system to communicate with solid-state drives to determine which of the SSD is pleasing and not used, and is ready for erasure and replication. If th

http://blog.csdn.net/killmice/article/details/42745937 The test tool FIO is read sequentially as an example, with the following commands: fio-name IOPS-RW = Read-bs = 4k-runtime = 60-iodepth 32-filename/dev/sda6-ioengin E Libaio-direct = 1 where rw = read for random reads, BS = 4k for each read 4k, filename specifies the corresponding partition, here I am/dev/sda6, direct = 1 means the cache through Linux Test SATA Hard Drive, SAS hard drive, SSD har

Recently has been engaged in the object detection play, before using the FASTER-RCNN, the accuracy of 73.2%, the effect is good, but the recognition speed is a bit short, I use the GPU is gtx980ti, recognition speed is about 15fps. Recently discovered SSD ( Single shot Multibox detector) This paper has a good effect and speed, I have experimented with it, the speed is indeed much faster than FASTER-RCNN. The following is a two-part introduction. The f

Let's look at the difference between SSD and traditional mechanical hard drives. The following figure can be seen, the traditional mechanical hard disk by the disc, magnetic head, rotating shaft, control motor and other parts, working disc rotation, magnetic head positioning in the disc at the designated location for reading and writing operations, in a sense and the structure of the old phonograph similar. The advantages of traditional hard disk are

In fact, the frozen phenomenon of solid-state hard disk is not concentrated on the SSD, but the whole problem related to the hard disk, many users think that the crash itself is the problem of solid-state hard disk, we in today's article also together to analyze what is the problem of the system crash. SSD freezes cotton How to do solid state hard disk use detailed Let's take a look at the crash prob

I finally installed UbuntuKylin13.04 on the SSD. It was very difficult! It is recommended that you install it using USB live. The speed is very fast. The actual measurement is 128 gb ssd + 8 GB memory. The installation is completed in about 8 minutes during online download. Step 1: Disable the ext4 log function Note: The system mount can not disable the log function, so you need to use the installation of t
