After the university's use of the old Acer 5740dg retired, at home as parents watch movies, but because the notebook's original Western Digital 320G space is about to be exhausted, and after years of use, it also inevitably produced some bad sectors.
Now face a few problems:
1, has been sent to all my mobile hard disk brother, 2, do not want to tolerate the hard disk usb2.0 so painful transmission speed, usb3.0 want to use but the laptop does not interface, 3, CD-ROM drive has never been used to buy computers, comprehensive Considered, so I plan to cut off the optical drive, buy a "drive hard drive bay" to install a new hard drive. There are several major considerations in this regard: First, to achieve expansion of the hard disk, two, you can think high-speed data backup also supports hot-swappable, three, with two hard disk groups soft Raid then you can double the speed of disk read and write. Think of it and do it.
after:Preparation + Must-haves:
1, a notebook (this is not no good, here is Acer 5740DG),
2, a new 500G blue disk (Interface mainly look at the computer, this is a broken notebook is SATA, then bought Western Digital 7200, 350, now dropped to more than 200),
3, the hard drive drive bay one ( this must be asked the next shop, whether to support their own notebook, according to the choice of notebook models, or bought can not be used, the optical drive drive bay bracket should be the largest Think pad series, a search a lot ),
4, screwdriver, personal feeling can always use it, the notebook will always change, the screwdriver is always in use
As shown below
2, began to remove the computer, 5740DG's hard disk panel has 5 screws, removed one by one
3, you can see the original 320G hard drive, take a look at the top of the hard disk should be a wireless module, the hard disk next to a small piece of the 3G module is said to be a reserved slot, temporarily regardless, where you can see the optical drive without a screw lock With the direct drive, 88
Hard disk tray, new 500G hard disk, and the introduction of the optical drive to take a photo
After the hard disk tray fits in with the new 500G hard disk, the old hard disk and the optical drive that was launched will take another photo
4, because the hard disk tray is not the original goods, so there will be some in and out of size, the more anxious, the more is no way to put the optical drive interface right, engage in a half-day to find a successful person in the forum, and finally fumbled to the law, Its strong insertion, the picture was provided by the racingpht of the zol Acer forum
5, according to the above figure, the left is to see the interface, the right is the drive position of the screw, but with the zol Acer Forum racingpht difference is that I was facing the left side of the optical drive tray circuit board lightly clicked, Easy to get.
6, finally the drive bay and notebook fit together, Khan, but, a boot and then encountered problems, my laptop BIOS version 1.09 version is too low, does not support the APAPI mode of the second hard drive, system self-test will not go, Had to unplug the cradle, quickly download the latest 1.28 from the Acer official website, easy brushing, re-enter the bios you can see the second hard disk
7, here is the hardware part of the Bahrain, and now began to engage in software, the principle of soft RAID is simply to use more than WIN200 system comes with the disk management tool, the two or more of the composition of the dynamic disk with a district volume, It can achieve the effect of increasing the hard disk read/write speed to (the lowest speed among these hard disks) multiplied by n. After my hard disk partition, the final effect C, D, E is a simple volume of the original 320G, F, G, H is a new 500G simple volume, the last I disk is a stripe with two hard disk groups. Under the speed test
8, first HD Tune benchmark read test, 320G test results here with 500G, in line with the 5400 speed mechanical hard drive standard, but because HD Tune is a single-threaded speed measurement software, and affected by temperature and vibration, etc., so The result can only be used as a reference.
9, the next is the ATTO read and write speed test, first the original 320G E disk test read and write, large files to read and write are basically maintained at 65MB / sec or more, normal
Then is the newly added 500G hard drive in the F drive partition, it is estimated that the Western Digital has read the firmware to upgrade the disk, 500G read and write files actually have 80MB/second, faster than the original 320G 15MB/second, not bad
Last but not least, the exciting moment came when the two-disk hard drive, with a floppy disk and I drive, was really good at reading and writing speeds. The speed was basically 110MB/sec, basically reaching the 320G speed multiplied by 2 and spreading flowers.
At this point, the expansion of the hard disk + RAID is completed, and some games and frequently used documents are put into the striped volume. It is indeed felt that the speed is improved. However, since the striped volume cannot be recognized by the system boot installation program or GHOST restore program, the operation is performed. The system still cannot be mounted on the striped volume. This results in disk reads and writes for most system operations that can only be performed at the original speed. There is no change in the WIN7 rating.
So the next upgrade goal will be positioned as:Use a small-capacity SSD as a system disk, run WIN7 with a common SSD on the market with a read/write speed of up to 250MB/sec, and add a second hard drive to increase the WIN7 score to 7 points or more. Saliva overflowing. Very good, next time
