first time
1: Hard disk selection:
The longer the maintenance time, the longer the better, the previously used 2.5-in-hard drive is very good, now changed the surname Hitachi recently trial
The WD new small scorpion hard drive 5400rpm is only 500 mA current demand, and it does not need to use it.
Add external power supply, very good effect, especially the noise level is extremely amazing, do not attach your ears on the box
Noise (even when it is exchanged), it is recommended.
2: Selection of boxes:
I used to recommend moving stars because of a piece of mobile star using Ali big chips under the next time.
Performance has been good, recently read the market, the move star has a little stealing, generally replaced the CS8818
Chip, or even GL811. The shape is more beautiful, but it is ... Everyone is choosing or choosing a chip.
Broadlocks follow: NEC> Ali> GL.

1. Why do you choose a hard drive hard drive box in the form of a brand mobile hard disk?
This is mainly considered cost-effective, and now the brand mobile hard disk is worthy, such as the patriot's storage king,
20, 30g is more than 1,000, 60g is two thousand. And choose your own DIY, generally 40g 600
You can buy more, you can buy 60g of 900.
2, why choose a notebook hard disk instead of a desktop hard drive?
As everyone knows, desktop hard drives are more cheaper than notebook hard drives, Seagate 80G desktop hard drive
More than dozens of money than Hitachi 40g, why not choose a desktop hard drive
Choose a notebook hard drive? Here is mainly two aspects:
First, mobility. The hard disk of the desktop is 3.5, the notebook is 2.5, this volume is a lot, and
And the hard disk box used by the typographic hard disk is also very thick, so the form of the desktop hard drive is more mobility
difference. But if you don't consider mobility, just say I want to buy a hard drive backup data, this is
This considers the desktop hard drive.
Second, USB is powered. The terminal of the desktop hard drive is generally large, and the maximum supply current of the USB port is 500
MAA, far from meeting the current $ 3.5-inch hard drive job. If the hard disk is less than the rated current
It is easy to make an error, or even damage, the manifestation is often lost data, or when it is formatted,
Display errors; or cannot be used on some motherboards. If this can only choose to use an external power supply
HDD Enclosure. Notebook hard drives generally do not have such problems, basically can be used directly on the desktop, even
The case where the power supply that appears on this website can also be solved by PS2 port.
3, why choose a low speed notebook hard drive instead of a high-speed notebook hard drive?
If the hard drive is used directly on this book, there is no doubt that should be 5400 rpm, and if you use it
Hard disks, 4200 rpm is already enough, there are three considerations here.
First, the rate of access is. The actual rate of USB2.0 should be <20m / s, under this premise, access data
The bottleneck is not on the hard disk, in fact, 4200 rpm and 5400 rpm have little effect on the access rate of the mobile hard disk.
Second, noise and heat generation. 4200rpm relatively relatively low noise low, huh, huh.
Third, the price. 40g or less of the laptop hard drive high speed and low speed price difference is not very big, but 60g
The above difference is relatively large, and it is generally possible to be a few tens of pieces to one or two hundred pieces.
4, what brand of notebook hard drive?
Personally recommended, huh, huh, huh
5, what brand of hard drive boxes?
Now there is a lot of false IBM, Sony's box, very cheap, 30, 40, can be bought,
I can't do it for two or three days, I will read the hard disk. Personally recommended to move around 2.0, 80, or some New
Man Mobile King, 120 (price is only for reference, huh, huh)
