We should have seen a discount promotion for Virpus merchants to launch SSD Linux/Windows VPS hosts in the summer last weekend. The user reputation of Virpus merchants was not very good before it was acquired, and does not support the refund policy. However, in order to experience its stability and performance, the old Left has bought a Linux ssd vps with 12.75 M

When asked whether traditional raid can be built on SSD, the first response should be "yes, but trim command support is required ". On the Internet, we can also see that many people use SSD to create raid, but basically it is configured as RAID 0 or raid 1. Few people will build RAID5. Why? The answer is very simple. If you configure parity-raid like RAID 5 on the basis of

SSD provides incredible performance for the storage system, which is 10 times higher than the fastest mechanical hard disk. However, because SSD write performance is affected by block erasure latency, SSD is usually used as a read device. However, this does not mean that SSD does not improve the write performance. In f

I haven't updated my blog for a long time. A while ago, I experienced my first job hopping, which is much harder than I thought. After all, it was the first job and it was quite sad to leave. The new job has just begun, and we hope everything will go well. This blog was written during May 1, and is officially posted today. It is a good habit to write a technical blog. I want to keep it! When I was in the previous job, I always wanted to try Flash/SSD

What is a solid state drive and how long is the SSD life?SSD refers to the use of flash memory chip composed of SSD SSD, is the use of flash flash memory particles as a storage unit, no longer using traditional mechanical storage methods, the use of simulated virtual hard disk access and sectors, etc., can also simply

Years later, the use of their spare time and intermittent will caffe SSD source read, although the middle due to work for a period of time, but finally completed successfully, SSD source reading is also this year's annual plan of the more important one of the content, completed or very fulfilling. after reading the code, one of the biggest experience is that before the paper a lot of confused my details now

As SSD How to use? How do you look at 4k alignment? 　　About as SSD software: As SSD is a professional SSD (SSD) transmission Speed Test tool, it can not only test the speed of solid-state hard disk reading, but also can detect

Focus on SSDs has been around for some time, the previous few years SSD capacity is small, more importantly, its limited life and expensive prices so that SSD can only be used as a storage area of the accelerated media exist, if anyone who want to use SSD as a disk array, the system is a bit too crazy. As a result, in previous years, both academia and industry ha

What is SSD? A Solid State Disk (Solid State Disk or Solid State Drive), also known as an electronic hard Disk or Solid State electronic Disk, is a hard Disk consisting of a control unit and a Solid State storage unit (DRAM or FLASH chip. The interface specifications, functions, and usage of SSD are the same as those of common hard disks, and the product shape and size are also the same as those of common h

PCIe SSD introduction and application (I), pciessd introduction and application SSD with SATA/SAS interfaces has been available for more than a decade and has been widely used in the personal consumption field. However, its performance still cannot fully meet the high throughput and low latency requirements of enterprise users, A few years ago, the world's first PCIe interface

Do you want to partition your SSD? Some people say that SSD is best not to partition, will affect the use of performance and life, is this so? On the SSD is good or not partition good, is a more interesting question, which will involve a lot of SSD related knowledge, the following small series to detailed introduction.

OSX: it may not be a good idea to enable the ssd trim function. A long time ago, since people started loading SSD to Mac machines and OSX began to support TRIM, people began to pay attention to enabling the TRIM function of OSX to optimize SSD performance, this is the slowest operation for SSD, especially when there ar

The use case is simple, I want to use both SSD disks and SATA disks within the same machine and ultimately create pools pointing to SSD or SATA disks. in order to achieve our goal, we need to modify the crush map. my example has 2 SATA disks and 2 SSD disks on each host and I have 3 hosts in total. To revoke strate, please refer to the following picture: I. Cr

From: http://yblog.org/archive/index.php/11734 The biggest difference between an SSD and a general traditional hard drive is that its memory-to-life ratio is limited, and the fast Memory (flash memory) in the same data area) SSD memory uses a special algorithm built in the control chip to evenly distribute data to the fast-moving memory chip in different regions. For Ubuntu Linux, my Acer 3750g laptop is Ub

Some time ago in developing a system that uses SSD for caching, a large amount of disk caching occurs when writing data at high speed. Too much disk caching is very dangerous if there is a problem with the machine if it is not written to disk in a timely manner, which can result in a lot of data loss, but if the data is brushed into the disk in real time, the write efficiency is too low. In order to understand the Linux system of this disk write chara

SSD solid-state hard drive How to optimize the use of solid-state hard drives more slowly how to do? Today, this article mainly with the introduction of SSD solid State hard drive optimization of some knowledge, mainly for some netizens often said they buy the solid-state hard disk speed is not fast, or feel that the SSD and traditional HDD hard drive gap betwe

From the advent of SSDs, to the present popularity, in fact, only a few years of time. During this time, SSD performance and capacity, especially the price, have undergone a great change. Have to say, now the capacity of SSD is getting bigger, the price is also getting cheaper. However, compared with the traditional HDD, there are some gaps in the capacity and price ratio, especially the large capacity is t
