1. SizeThe M.2 standard allows modules with widths of 12, 16, 22 and MM, lengths of 16, 26, 30, 38, 42, 60, 80, and MM. Commercially available m.2 modules are available in sizes of 30, 42, 60, 80 and MM respectively.eg:2242 22mm Width 42mm length2260 22mm Width 60mm length2280 22mm width 80mm long common　　　　2.

The company's ERP system has a large amount of data, with 40 GB of data and 90 + concurrent users and 1000 + connections. The original IO performance cannot meet users' operation response requirements, and report query is slow, all the indexes have been done, and the index is re-built once a week, but the problem still cannot be solved. To this end, the company purchased the dell poweredge R720xd server, which supports two arrays and 24 hard disks, dual-CPU, 64 GB memory, more awesome. We have c

How to adjust the boot sequence of SSD after installing solid state hard disk in computer 1, after the computer restart, point del into the motherboard interface, go to boot, you can see the start of the sequence of display; 2, the problem is not seen in the startup preferences of solid-state drives, and then enter hard disk Drive BBS priorities; 3, in the choice of the inside can see solid state hard drive and mechanical hard dri

To the introduction of solid-state drives, compared to the old mechanical hard drive, SSD solid state hard disk is said to be the same as the rocket speed, the installation of solid state hard drive after the Win7 system, whether the boot or operation has a quality upgrade, but many friends may not know, the use of solid-state drives there are some need to know the optimization methods, Allows your solid-state drives to perform optimally in Win7 syste

No solid-state drive, fast CPU, and then a powerful graphics card, are useless, because of the "barrel principle", the bottleneck is here ah. Today's SSD prices have fallen a lot, I remember last year I bought a 120G SSD is nearly 600 yuan, and now only need less than 400. The way I introduced the SSD and transfer system is simple (and very safe), but still need

One problem for users who want to equip their old Mac with a third-party SSD (SSD) is that the OS X system does not turn on TRIM support for Third-party SSDs. TRIM is a system-level command that allows the operating system to communicate with solid-state drives to determine which of the SSD is pleasing and not used, and is ready for erasure and replication. If th

http://blog.csdn.net/killmice/article/details/42745937 The test tool FIO is read sequentially as an example, with the following commands: fio-name IOPS-RW = Read-bs = 4k-runtime = 60-iodepth 32-filename/dev/sda6-ioengin E Libaio-direct = 1 where rw = read for random reads, BS = 4k for each read 4k, filename specifies the corresponding partition, here I am/dev/sda6, direct = 1 means the cache through Linux Test SATA Hard Drive, SAS hard drive, SSD har

Recently has been engaged in the object detection play, before using the FASTER-RCNN, the accuracy of 73.2%, the effect is good, but the recognition speed is a bit short, I use the GPU is gtx980ti, recognition speed is about 15fps. Recently discovered SSD ( Single shot Multibox detector) This paper has a good effect and speed, I have experimented with it, the speed is indeed much faster than FASTER-RCNN. The following is a two-part introduction. The f

There will be a workaround for the hard drive)Bo main dry tears, inadvertently saw MASHCI-AHCI not open, somewhere, feel this may be the cause of the problem. Naïve thought to change the registry, Biso Open AHCI mode is OK. Never thought the blue screen a support one, can not open the machine how to break. The landlord naïve believe that the Internet

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 MB of memory for the Seattle data center for t

The advent of solid-state drives, just let the computer really into the rapid development of the era, the previous computer no matter how good configuration is always mechanical hard drive drag, because slow speed lead to low performance, startup software, etc., now has a solid state disk when the system disk and cache disk, you can solve this problem slightly. The difference between solid-state hard drives and ordinary hard drives: solid-state drives are the last of the five major computer har

The upgrade cost reached $45000000 and was the biggest transformation investment since Linode was founded (11). SSD StorageThe SSD array storage system used in Linode is not a popular hybrid hard disk at present, and it uses the server-level SSD hard disk with battery back-up power. The price is very expensive. 40Gbps NetworkEach Linode host server uses a Gbps

In fact, the frozen phenomenon of solid-state hard disk is not concentrated on the SSD, but the whole problem related to the hard disk, many users think that the crash itself is the problem of solid-state hard disk, we in today's article also together to analyze what is the problem of the system crash.

First, you have to have enough memory to accommodate Windows XP, and now the memory is not expensive, 2 GB is enough. I directly used 4 GB, 32-bit system can use m
