I am the fastest hard drive! — Two 7200-rpm 500G hard drives modified by hard disk RAID enclosures

The landlord hasn't written an article for a long time because it is lazy and recently bought a bit of swift goods to share it. It is an article written by the shoe. But the landlord is also an electronics enthusiast. Small Geek.

What I shared today is my article on using two 7200-rpm 500G hard drives to go through hard disk RAID boxes.

Good show behind!

Reasons to purchase

The landlord is a student and counts as half a loss. Because I particularly like electronic products, I often buy and buy! . Why don't you say these things, because this thing is indeed degenerate. Two months ago, the landlord prepared his birthday. You know, then I think right away I should buy some stuff and fill up the electronic products that I don't have. Then I think of mobile hard disk, there are several U disk. And I don't have a mobile hard drive, nor should it be normal. But recently encountered some things that must be bought. It is not the big sister who lost anything but the teacher's criticism!

Everyone is the picture first. It seems that there is a lot of nonsense. Everybody may want to ask what has been criticized with the mobile hard drive what "hair" relationship, in fact, this is the landlord holds the Department of computer staff, the Department of Department usually engage in activities to take pictures, ah, after the photo is processed, I sent the teacher to delete Well, not much memory is used to save these. After the sudden teacher asked me to ask, was the event still there? I said that after the deletion, I was beaten.

I think, you do not give me U disk, there are so many photos saved, and now the risk of network disk is so big, but also speed limit, you know a hundred X cloud, the most horrible today upload something tomorrow may be the network disk going offline! For those who take the school wages, they will not care about buying wages for this. (300 yuan)

Then the reason is to want to buy a finished mobile hard drive but you know GeeK is a hardware madman, 500G 5400 turn brand mobile hard disk at least 300 base price. And it will cost me a month's salary, I bought a hard disk box plus 500G 7200 rpm hard drive finished only 290 yuan is of course this is a good deal.

This can reflect the aunt worth the spirit!

Not long after you bought it, you know, put photos and put some A software to put some lossless music, learning materials and teaching videos to help the teacher (top secret). The remaining capacity is very urgent!

One method I thought of was that RIAD 0 has increased speed in hard disk expansion. The best of both worlds. Think of this because my computer hard drive is such a combination! However, the speed is more like catching chickens, knowing that this speed is not as expensive as buying an SSD. So I lost my home so much!

Understand that people are laughing next to how a SATA2 a SATA3? I do not know how he handled it! God pointing!

The first hard drive I bought at the time was HGST HTS725050A7E630 when it was bought at 260. The old hard drive box had been sold out at a low price! Hard disk box is 30 yuan

After less than two months of purchase, it was found that the capacity was not enough to be expanded. Why do you think about why I didn't buy 1TB? Of course there was no red ticket. Is there any article here? And the single-disk 500G power consumption is lower than the dual-disk 1TB power consumption, which is the most stable and stable. 1TB is generally a dual disk without a single disk stability! The brand behind the expansion was not HGST, but bought a WD black disk. Why not continue to buy HGST, the most important price.

I bought two abnormal noises in the past two months, and after the loud noises, my heart was cold and I thought that the hard disk was broken!

HGST's after-sales service is too much trouble and there are no physical sales. Only where you go to buy, where to go after the sale!

Then I chose a WD black disk, one is faster and after sale is quite good! The main dog east has a discount coupon and does not buy it, and the price is lower than usual. The main reason is that the seller will interest-free in three phases!

It should be said that the RAID 0 hard disk box! This I have considered for several days, choose to choose to go or choose the Arcasian 2.5" SATA dual hard disk array hard disk box USB3.0 model is DT-S2. Why choose him and choose in the dog east, because of the reasons, A few points before buying it!

Full metal shell

The same thing is cheaper than the Tmall, and the activities of the dog, 159 less than 8 yuan and 6 interest-free period.

Many hard drives with the same price are not fixed (200 yuan supports the RAID 0 price file), and they are not screwed. This is not reliable. This has 4 screws fixed to ensure the stability of the hard disk! Do not drop, shake.

Use a combination of feelings

Xiao Bai must ask why I did not tear down, and that two pieces of waste SSD buy a bracket combination RAID 0 speed so you can quickly go to heaven!

My answer is that due to interface problems, the speed of the dual solid-state hard drive can't finish, wasting!

Technical analysis: The theoretical bandwidth of the USB3.1 GEN1 architecture is not 10GB/s. The fastest theory of USB3.0 is only half the 5GB speed. The theoretical value of the fastest bandwidth of SATA 3 is 6GB. This is too much loss.

Although Tmall has to go TYPE-C hard disk box. But he does not seem to have a fixed screw, more like that array box!

The most appropriate USB3.0 is the most appropriate one is a high-speed SSD or two 7200-rpm mechanical hard disk so that you can use the USB3.0 performance as much as possible!

Finally, the last speed-loading software reflects B. The test system is Microsoft!

to sum up

advantage

The speed is soaring, see almost all the above formats can run!

Shortcomings

The disadvantage of RAID 0 is that the read and write speeds are improved. However, fragmented files do not increase in speed.

And this hard disk box does not understand the problem of using software testing 4K data test does not come out?
