How to install XP on Lenovo ThinkPad E40 The following describes how to install XP in E40: 1. Change the SATA mode to compatibility. Restart XP before it is officially installed. Press F1 to enter the bios, select Config → SATA → mode, and change from ahci to compatibility. In this way, the XP installer has been cheated, make it think that your SATA hard disk is

is a two-dimensional array [don't tangle, in order to make it easier for me to convert it to JSON], where type has only two values of 1 and 2,Now you need to move the type=1 element into the $new array, type=2 to the $old array. Is there any way besides using the loop? Attach JSON: [{"id": "Ten", "Type": "1", "CPU": "Intel Xeon e3-1241v3", "Cores": "4", "Ram": "+", "hard_drive": "1TB SATA", "Port_speed": " 100Mbps "," Transfer ":" 20TB "," IPMI_KVM ":

Ceph environment setup (2)1. There are three layout hosts: node1, node2, and node3. Each host has three osdks, as shown in figure. osd1, and 8 are SSD disks, 4 is the SATA disk. Each of the three hosts has a Monitor and an MDS. We use osd1, 3, and 4 to create a pool named ssd, in the form of three copies, osd0, and 2, 4 to build a Pool named sata, in the form of Erasure code, k = 2, m = 1, that is, use two

SAS (Serial Attached SCSI) is a new generation of SCSI technology, which is the same as the popular Serial ATA (SATA) hard drive. It uses Serial technology to achieve higher transmission speeds, and improve the internal space by shortening the connection line. SAS is a new interface developed after the parallel SCSI interface. This interface is designed to improve the efficiency, availability, and scalability of the storage system and provide compatib

of the computer. So we say, now the bottleneck of computer hardware is the traditional mechanical hard disk. That being the case, we can see that improving the performance of the hard drive can improve our experience of using the computer, so SSD turned out. SSD because of its storage medium and principle and traditional mechanical hard disk is completely different, so greatly improve the read and write speed and greatly improve the random read and write performance, this is a leap for the com

ObjectiveHello everybody, welcome to watch the article of the small fish. In the previous issue, we briefly explained the simple differences and pros and cons of HDD (mechanical disk) and SSD (SSD), but this is just a small opening in the future. I will give you more knowledge and interesting facts about solid state. In this issue, we talk about the interface of the story, a lot of people will ask, interface is not two kinds of it? SATA and m.2 interf

I. Category of disks Disks can be divided into ATA (IDE), SATA, SCSI, SAS, and FC disks by interface type. According to the disk chip composition, it is divided into SSD and HDD. Because the mechanical hard disk is still the mainstream configuration, we call SAS, FC and SATA both refer to the mechanical hard disk. The following is a brief introduction to Baidu Encyclopedia: ATA,The full name is AdvancedTech

How do I differentiate the solid-state drives of the M.2 interface? M.2 is Intel led the development of a new generation of interface standards, with a smaller size, faster interface features, the current main specifications are the following, mainly the length is not the same. The image below is a two-m.2 SSD: The short one is the Shadow Armor War m.2 128GB Long is the Shadow Armor War m.2 256GB These two are m.2 interface, how to distinguish which is the PCI-E SSD

SSD, SAS, SATA Real-time SSD is best; SAS io is faster; SATA is the cheapest and should be used as a storage server (low frequency of access) The following major sectors are excerpted from the network: MLC SSD and SLC SSD SSD (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

Recently I changed a new computer, and the company required to use the XP system for the project, but the blue screen is displayed every installation. Go to the Internet and check whether you want to change the hard disk mode in the BIOS to switch ahci to the IDE mode, and then install it. However, in the days to come, I found that it was difficult to handle the problem. I had to go to the network and check if I had to install the ahci driver, then I changed the hard disk mode to ahci, but I tri

NGFF (Next Generation Form Factor), as the name suggests, is the standard of Form Factor. It is tied with NGFF for 2.5 "instead of PCIe. (In addition, NGFF has now been renamed M.2. We 'd better keep pace with the times and change it to M.2 .)PCIe is a bus standard, tied with SATA.NVMe is a new transmission standard for hard disks and replaces the current AHCI.Why do people always associate NGFF/M.2 with PCIe/NVMe? This is because the SSD in The M.2 shape supports the PCIe bus first in

SAS interface technology can be backward-compatible with SATA. Specifically, the compatibility of the two is mainly embodied in the physical layer and the protocol layer compatibility. In the physical layer, the SAS interface and SATA interface are fully compatible, SATA hard disk can be directly used in the SAS environment, from the interface standard,

applications of solid-state hard disk generally have different interfaces. Solid-state hard disk compared with traditional mechanical hard disk, interface specifications are more easily confused by the initial users, the following is described below: 　　Mainstream common--sata interface SATA interface is no longer a new technology, since 2001 SATA 1.0 to the cu

The hard disk interface is a connecting part between the hard disk and the host system, which transmits data between the hard disk cache and the host memory. The different hard disk interface determines the connection speed between the hard disk and the computer, in the whole system, the quality of the hard disk interface directly affects the program running speed and performance. General classification and large class classification From the overall point of view, the hard disk interface is d
