Nor and NAND
Nor and NAND are both Flash technologies. Nor is developed by Intel. It is somewhat similar to memory and allows direct access to any memory unit through an address. The disadvantage is: low Density (Small capacity), low write and erase speeds. Nand is developed by Toshiba. It features high density (Large capacity) and fast write and erase speeds. However, it can only be accessed after address conversion through a specific IO Interface, some are similar to disks.

4. When using XFS, the default block size for PostgreSQL is 8KiB, but in the current Linux environment, running "Mount XFS" will eject the "feature not implemented" error, so the block size should be adjusted to 4KiB. An increase in the number of allocation groups means that more paral

It has become fashionable for computers to upgrade their solid-state drives to enhance their speed and nuclear performance. However, a variety of different computers, can upgrade SSDs, how to upgrade SSD to achieve the speed of nuclear performance, but the biggest problem of upgrading SSDs. In order to meet the needs of upgrading the SSD friends, this computer upgrade S

Ii. Install mSATA SSD solid state drive for T430
I bought a block Jixing LMT-128M3M 128G SSD mSATA SSD. The installation steps are also very simple.
Remove the battery of the laptop and unplug the power. Remove the cover of the memory stick and mSATA slot, and the mSATA slot
Can ssd be used as a redo disk? 1. ssd has write wear and tear, and the ssd write performance is not very good. ssd is only very good for random reading, because it does not need to be searched. Ssd is easy to damage. 2. index tablespace and temporary tablespace are good cho

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
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
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
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

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

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.
