SSD solid-state hard disk capacity faster? Theoretically speaking, the larger the solid-state hard disk capacity, the better the IPOs performance, the faster the random read and write speed. In layman's terms, because solid-state drives are made up of multiple storage chips, the larger the capacity, the more chips there are, and the faster each chip reads and writes, but the faster a plurality of chips read and write together. However, it is worth m

The SSD (Solid state disk or Solid Drive) is also known as a solid-state drive, a new generation of hard disk products that use flash pellets as storage components. SSD hard disk has the characteristics of high speed and security, but it is hindered by its wide application because of its expensive and limited capacity. However, with the continuous downward flash product prices,

No solid-state drive, fast CPU, and then a powerful graphics card, are useless, because of the "barrel principle", the bottleneck is here ah. Today's SSD prices have fallen a lot, I remember last year I bought a 120G SSD is nearly 600 yuan, and now only need less than 400. The way I introduced the SSD and transfer system is simple (and very safe), but still need

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

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

similar structure, u disk can be used as a solid-state hard disk? Now u disk prices continue to slide, the 8GB u disk most also sell to fifty or sixty Yuan, 16GB USB drive is more than 100 blocks full of streets, this and thousands of dollars of solid state drives, compared to the formation of a very large contrast. From a structural point of view, U disk and SSD have many similar places. First of all, as stored data tools, they use flash as a storag

Failure phenomenon: SSD solid-state hard disk has been gradually recognized, we serve the user community has also been the use of solid-state hard disk users, but not too much knowledge of solid-state drives, so we need to use the solid-state hard disk testing, and will detect information feedback user current status. Solution: We like to use Hdtune to look at the smart information of the hard drive when we test HDD. In the

SSD speed slows down cause analysis: Because the format of the hard disk is not right, SSD hard drive to give full play to its stable speed performance, it needs to carry out 4K on it, but many people have installed the system and many software, do not want to destroy the data on the 4 K for its difficulty. There are already such tools on the Internet, but often only on their non system disk, the main disk
