Last October, Apple updated the latest Mac Mini, the new Mac Mini is still a very attractive device for some consumers seeking micro-desktop devices, but its 5400-turn mechanical hard drive has been a lot of user spit slots in SSD-SSD king today, The disadvantage of a mechanical hard drive restricts the user experience of Mac Mini, but don't worry. Today, the small series to bring you a netizen to provide 2

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

Transferred from: http://lanbing510.info/2017/08/28/YOLO-SSD.html Prior to the emergence of deep learning, the traditional target detection method is probably divided into regional selection (sliding window), feature extraction (SIFT, hog, etc.), classifier (SVM, adaboost, etc.) three parts, the main problems have two aspects: on the one hand, sliding window selection strategy is not targeted, time complexity, window redundancy On the other hand, the characteristics of manual design are poor. S

In a variety of test mix scenarios, the combination of 10 (combination 10:SSD * 2, RAID 0, Xfs,wb,nobarrier,noop) has the highest overall performance, so it is the benchmark, and the comparison of other schemes, the following table is the comparison of the combinations and combinations 10:650) this.width=650; "Src=" http://dp.imysql.com:8080/files/upload_yejr_imysql/SAS_VS_SSD_MySQL_OLTP%E5%AF%B9%E6% Af%94%e6%b5%8b%e8%af%95%e8%a1%a8-20120907.png "styl

does not mean that the hard disk can not be used, but performance will be reduced, there is noise, such as driving a car, the mechanical structure will appear aging, so need maintenance, but mechanical hard disk use for 5-10 years completely no problem, or even more. Solid-state hard disk life standard is generally written or written capacity, the calculation of capacity units are not intuitive, including 4 K, 8K of random write capacity, usually in TB, PB units to calculate, the general profe
