How to buy a solid state drive

Solid-State drives (SSD) are now not new, the popularity of these years is very fast, solid-state hard disk is composed of erasable storage particles of the new form of storage products, can be used in desktops, notebooks, due to changes in storage media, greatly enhance the storage speed.

But there are still many users in the face of solid-state hard disk doubt or puzzled, because of various reasons still reluctant to buy solid-state hard drive, this time I will answer for you some of the small knowledge of solid-state hard disk, to help you understand, select, use solid-state drives.

(I) Why buy solid-state drives?

Why write this paragraph? Because many users are still skeptical about using solid-state drives. I believe that, in addition to the price of expensive, solid-state hard disk relative to the mechanical hard drive is not any inferior. This content is written to reassure users who are still skeptical of solid-state drives, and if you already know and are determined to buy a solid-state drive, you can ignore it.

Physical structure of solid-state drives: storage and control of chips on a piece of PCB solder, no mechanical parts.

The first question before buying a solid-state drive must be: What is a solid-state drive better than a mechanical hard drive? Solid-state hard disk because of the different physical structure, it is simply more than mechanical hard disk is too much: its small size, light weight, fast, low fever, strong, seismic resistance, a wide range of temperature, performance attenuation low.

In fact, the current market of solid-state drives, if not a failure, the normal use of ordinary individuals can be used for more than five years. We often encounter a problem is: The computer is more and more slow, this is the structure of the mechanical hard disk caused by the use of Motor drive disk rotation, by the rocker ARM control probe read/write, this form of work lead to a long time due to mechanical wear, aging and reduce the speed of operation. Solid-State drives, which read the data on the storage medium directly through the circuit, do not reduce the speed because of the increased use time until the storage unit physical erase number reaches the limit and is completely damaged.

Q: Solid state hard disk is better than mechanical hard drive?

A: Fast, small and durable.

Q: Is the solid-state drive just powering on?

A: Not so, in addition to the short boot time, solid-state drives in the running, installation of various applications (including software, games, etc.) faster than the mechanical hard drive. To put it simply, you can feel the change in the solid-state drive all the while using the computer.

Q: What is the solid state drive faster than a mechanical hard drive?

A: In the continuous read-write rate, SSD is a mechanical hard disk 3~5 times, random Read and write rate, up to 7 times times. Combined, the daily use can be at least 3 times times faster. For example, to extract a large compressed paper file, mechanical hard drive if it takes half an hour, the solid-state drive may take less than 10 minutes, read the game, the mechanical hard drive needs more than 1 minutes, solid-state hard disk only need 20 seconds. These experiences are not understood when you are not using a solid-state drive, but once used, 99% of users say it is hard to endure the speed of a mechanical hard drive.

Q: What are the drawbacks of solid-state drives?

A: It's expensive, but there's nothing else. At present, the mechanical hard drive is probably 2tb=500 yuan, about 0.25 yuan/gb, while the SSD is probably 256gb=700 yuan, about 2.73 Yuan/GB, the unit price of solid-state hard disk is about 10 times times that of mechanical hard disk.

Q: Solid-state hard disk reliability is not relatively poor?

A: There is a foreign website to do storage products reworks statistics, the results show that the failure rate of solid state hard disk is lower than the mechanical hard drive. There are no 100% problems with the electronic products, but now the technology has been very mature, said the solid state hard disk is unreliable, easy to go without problem, is groundless.

(II) How to use solid-state drives?

In addition to the solid state of the hard drive itself is not known, there are many people are the use of solid-state hard disk is puzzled. "What, to use the SATA III interface?" To turn on 4K alignment and set AHCI mode? I'm going to be fine. ”

In fact, about the need to set up solid-state drives, has been a long time ago the problem, the 08 after the basic computer has been with the original SATA III interface, the default to open AHCI mode, regardless of Mac OS X or Windows 7/8/10 in the installation will be 4K alignment. That is to say, today's hardware and software have been all ready for solid-state drives, you just need to install the use on the line. Of course, if you are the extreme users of the 1% who are determined to install solid-state drives with XP or older operating systems and antique old PCs, please go to Baidu for more help, but this article is limited and cannot be given detailed answers.

Q: What is the use of solid-state hard drives?

A: For today's 99% of computers, it will be fitted with a mechanical hard drive. The premise is 5 years of production of Pc,win 7 and more operating systems.

Q: Is there anything else to be aware of using solid-state drives?

A: No, really.

(III) How to select a solid-state drive?

In recent years, solid-state hard disk development, large and small, the introduction of solid-state hard disk manufacturers have more than hundred, the current domestic market, the common brand has dozens of. Each brand, then, has several models and capacities, which are tricky to pick. So, how do we choose?

First of all, please allow the author of the current domestic market mainstream solid state hard disk for a general rating ranking:

Q: What brand of solid state hard disk is good?

A: I personally think that the current solid-state hard disk brand classification is as follows:

Top Brands:

Samsung, Intel

Recommended Model:

Samsung 850 EVO 120GB SATA Interface Solid State drive Jingdong price 369 yuan

Professional Brand:

Kingston, OCZ, Rui da, Pukot

Recommended Model:

Kingston V300 120GB SATA Interface Solid-state hard drive price 359 RMB

OCZ ARC 240GB SATA Interface Solid State drive Jingdong price 629 yuan

Reliable (factory) Brand: Flash di/Toshiba/Granville/Creative/Golden gram/Kingspec/Lite/Shadow etc.

Samsung and Intel are the most trusted solid-state hard drive brands on the market

The reason for this ranking is as follows: first, we want to understand the components of the SSD, a solid-state hard drive from hardware to software including: memory chips, controllers, firmware and software. In addition, there are after-sales service, brand protection and other factors included in the product. Buying a solid state drive is important in all of these areas. Therefore, combined with hardware and software resources/technology, enterprise scale, market channels, after-sales service and many other factors, the author of the above rankings.
