No Zuo no die, which is not upgraded to Yosemite, and then found that trim activated in mavericks is not working here, and prompts that trim enable is not suitable for this version. Then, the tragedy began. I found an old post and changed the kernel file according to the command. It was not suitable for Yosemite. Then I restarted the file and couldn't get in... A prohibited logo is everywhere, so it's cool. I haven't even done mavericks's USB flash drive installation disk yet. I can't even drop

In a variety of test mix scenarios, the combination of 10 (combination 10:SSD * 2, RAID 0, Xfs,wb,nobarrier,noop) has the highest overall performance, so it is the benchmark, and the comparison of other schemes, the following table is the comparison of the combinations and combinations 10:650) this.width=650; "Src=" http://dp.imysql.com:8080/files/upload_yejr_imysql/SAS_VS_SSD_MySQL_OLTP%E5%AF%B9%E6% Af%94%e6%b5%8b%e8%af%95%e8%a1%a8-20120907.png "styl

My Ubuntu12.10 is installed on Samsung's 64 GB ssd, so it is necessary to optimize it and give full play to the ssd's best performance. As for ssd's 4 K alignment, do not worry about it in ubuntu11.10 or later versions, because it has been aligned during formatting, we recommend that you manually partition the data by dividing it into one EFI boot partition. mb is enough, and then distribute the remaining data to/file systems using ext4, the Internet

Leave a mark on your own for Future reminders. 1) Restoring the USB flash disk using the system created by alien sprawn on a mechanical hard disk cannot be used in SSD. Because SSD does not have a recovery partition, you can only use a random System Recovery disc; 2) it is best to use a mechanical hard drive to guide the system before installing the SSD, and

The Windows 8 Index is a low-level service in Windows that specializes in providing fast searching for files, documents, and e-mail. In addition to creating a set of indexed data on the hard disk for the first run, Indexing Service starts every time a file changes or a new file is added, which is why many friends are complaining that their computer often finds the main reason for the hard drive (and there are other other things that can drive the hard drives). Reason Analysis:

"Ideas for solving problems" When the hard disk appears unable to format, partition, the general method is to initialize the operation. For mechanical hard disk generally using the method of low lattice, but now SSD hard disk and traditional mechanical hard drive is different, low lattice on solid-state hard disk meaningless. Because the low lattice refers to the rewriting of the disk interleaving factor, that is, the disk on the magnetic, solid-stat

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

Consumers familiar with the hardware may know that in many DIY hardware, the speed of hard disk performance in the system performance has a greater impact. Among them, the size of disk disc and the speed of seek time is the most important impact on the performance of hard disk, but the introduction of SSD has been the hard drive of the various parameters of the "brain behind." SSD due to the use of flash me

In March of this year, we introduced SSD-based Elastic Block-level storage for Amazon EC2 instances. After a few months of release, this new method of choice, known as general-purpose storage (SSD), has accounted for 90% of the newly created EBS volumes, we learned from customers' feedback that they like this consistent performance very much (pre-configured storage is 3 iops per GB) and increased to 3000 io

In Linux, check whether it is a solid state drive (SSD). Recently, we are preparing to test it. we need to check which machines are attached with an ssd hard drive. Google has seen many methods, but they are all in the dark, I don't know how to determine. Ssd hard drive seems to use the scsi interface, so it is determined by the drive letter name... in Linux, che

If you are using or preparing to buy SSD, you will certainly have some understanding of it. Now because the structure of solid-state hard disk and mechanical hard drive are fundamentally different, solid-state drives to achieve real performance needs of the trim instructions and other special means. But most people do not know, or are not aware of, in addition to some newer solid-state hard drives, partitioning and formatting for solid-state drives a
