maintain a long period of time and speed, SSD needs to be supported by trim, this allows SSD to erase the information that is marked on the fast-moving memory chip only during non-peak hours. This example is based on the ext4 operating system. In the case of ext4, after the division, the system cycle will actually erase
disks, and a lot of advantages, but things always have two sides, it also has some problems, written in the SSD data can not be directly updated, can only be overridden by sector overrides, before overwriting overrides need to erase first, And the erasure operation is not done on the sector, can only be done on the disk block, erase the block before you need to

Fnset will delete all the elements in the set, but fnvec will cause the program to crash.The reason is that when fnvec calls Vec. Erase (t), the elements behind t slide forward, and the iterator pointing to these elements is also affected. In fnset, if erase is called, the elements do
Lenovo ThinkPad E420 installed SSD to the CD-ROM drive bit, the BIOS can not find, PE to find SSD.

ATA Secure EraseThis procedure describes how to use the hdparm command to issue a Secure Erase ATA instruction to a target storage device. When a Secure Erase was issued against a SSD drive all its cells would be marked as empty, restoring it to factory default Write performance.DISCLAIMER: This would erase all your da
To the U.S. Mito software users to detailed analysis to share the use of the elimination of the pen tutorial.
Tutorial Sharing:
Well, the above information is a small series to the United States and Mito of this software users brought to the detailed use of the elimination of the pen to share the full content of the tutorial, you see the users here are now very clear about the use of the method, the elimination of the pen can erase the p
large, zoning is still very necessary. The advantage of SSD partitioning is that you can differentiate the system disk from the storage disk, and the reload system will not lose data from other disks. However, if the SSD is not partitioned, the reload system will be more cumbersome to consider backing up the data.
If the SSD capacity is small, and the computer
This release of update patch flash STORAGE Firmware update 1.1 is mainly for the 2012 section, there was earlier user feedback that some of the model on the unknown problems caused by the data saved in SSD was erased. If the consumer discovers the problem or cannot install the update on the machine, you can replace the SSD at the local Apple Store for free.
The security bulletin is as follows:
Apple has
large capacity of the mechanical hard disk drive to 4096 bytes (we say 4KB), and the computer file system (FAT, NTFS, etc.), Always used to operate hard disks in 512-byte sector units.While SSD read and write operation of different mechanical hard disk, SSD read and write the smallest unit called "page" (Common size of 4KB, depending on the specific particles), flash particles do not allow the same as a me

This is the weakness of the SSD, SSD for write performance is much lower than the read, may not be much faster than the physical disk.
Flash SSD is significantly slower when performing writes than when performing reads.

Let the SSD speed fly. Solid state HDD Optimization techniques Daquan
However, the other aspects of SSDs are obvious, so it has become the necessary hardware for most users installed. In terms of usage, SSD is slightly different from the traditional HDD, and it is necessary to go through a series of settings if the SSD is to really perform its performance. F
Simple Optimization of SSD hard drive on Ubuntu
1. Set the correct mounting option and enable TRIM.
After Linux is installed, this is very important.
To maintain long-term stability and speed, SSD needs to enable TRIM, which enables SSD to truly erase the materials marked on the chip during non-peak read/write times. T
Select the SSD attention and purchase skills sorted out to the small white user for reference, and Samsung 300e5k to replace the SSD process as an example for everyone real machine demo.
Before you decide to upgrade SSDs, you first need to evaluate whether your computer is suitable for SSD installation. Here need to explain, not that

Acquisition in 2009) was firstly presented and used in public manuscripts, This term describes in fact a multiple relationship between the target write value of the SSD and the actual write value, and the smaller the write amplification value, the more the solid life can be improved.To fully understand the write amplification, we need to understand the SSD's read-write mechanism first. We know that the SSD
Last night Apple released the official version of OS X 10.10.4. From the previous message, OS X El Capitan will start with a third party SSD TRIM support, but it looks like Apple will launch this feature ahead of time. Because OS X 10.10.4 has supported the TRIM on a third party SSD solid drive. Here's a little PC6 to tell you how to open the third party SSD TRIM
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
