how to wipe ssd

Although Samsung introduced the fix last October, it was reported last month that some of the Samsung 840 EVO SSDs face the problem of reading off the old data after it has been brushed into the new firmware. In view of this, Samsung issued the following statement in the afternoon of Friday: "In October, Samsung launched a 840 EVO SSD firmware tool that only fixes old data read-off, but a small percentage of users said they would encounter the same pr

With the popularity of SSD drive, its superior IO performance has been replaced by more and more traditional SATA and SAS disk, there are three kinds of common application scenarios: 1) Replace the hard disk of MySQL database, the community does not have the MySQL version optimized for SSD, even so, Direct upgrade of SSD drives can also bring about 8 times times

Recently, I bought two SSD hard disks and mounted them to the database. I put the virtual memory and temp tablespace and a controlfile on them. I hope to improve the efficiency of the database by taking advantage of the fast I/O feature of the SSD hard disk. after two weeks of running in the test environment, I moved to the formal environment. At noon today (3rd days), I received a call from my colleagues w

When a traditional outward scaling method becomes popular for MySQL, let's see what we have to expand (cheap memory? Quick storage? Better power supply efficiency ?) It will become very interesting. There are indeed many options here-I may encounter a customer using the Fushion-IO card every week. However, I saw an interesting option for them-they chose to buy an SSD and they could still read many pages per second (at this time, I would rather choose

When we run the SSD TensorFlow version, the following issues occur, and the command I run is: dataset_dir=voc2012/ output_dir=tfrecords python tf_convert_data.py \ --dataset_name=pascalvoc \ --dataset_dir=${dataset_dir} \ --output_name=voc_2012_train \ --output_dir=${output_dir} Through Baidu is not found GitHub above the issues above the answer, I am here to solve the problem to write out, hoping to help you play

Because of work, sometimes two computers are needed to work, and most people engaged in development are those pursuing computer performance, so the laptop is naturally not light, not to mention the two. I have been suffering from two computers for more than half a year, and finally made up my mind to install a system into a mobile SSD, carrying a non-hard drive computer and adding two mobile SSDS to reduce the burden. After one day's exploration, many

Linux SSD optimization policy 1. do not use a file system with logs. If you have the ability, consider a file system that supports ssd, such as ubifs. If not, use ext2 www.2cto.com 2. disable noatime nodiratime of the file system, because the access time will increase ssd write, there is no need to modify/etc/fstab, for example, change/dev/hda9/data ext2 defaults

Considering many algorithms including YOLO SSD, this series of onestage methods can not solve the problem of small target detection, after thinking that the problem is different from the feature map and the big target of small target.A paper solves this problem, that is, the RSSD algorithm R is the meaning of the rainbow means that multiple feature maps are fused as a classification standard.Paper: Enhancement of
