Now the price of 7400MB/s high-speed 4T has reached 999? Let’s talk about the price first. In the past year, even in the past six months, the price of solid-state drives has collapsed. The major flash memory manufacturers have desperately cut prices to clear their inventory.
It is true that domestic production puts too much pressure on them. Since the beginning of this year, the flash memory particles of domestic Yangtze River Storage have risen. Most of the domestic solid-state drives I mentioned here use the particles of Yangtze River Storage, which directly leads to a significant reduction in the price of domestic solid-state drives.
At the same time, a stampede happened, and foreign brands that used to be superior had to lower their prices. It's very simple, and they couldn't sell without lowering their prices.
For example, Samsung's high-speed solid-state 980 series, the price of 1TB capacity is now 439 yuan, and the price of the 980Pro top model is 549 yuan.
In October of 22, I just bought a desktop computer. At that time, I used Samsung’s high-speed solid-state hard drive. I remember very clearly that the price of 1T was about 720 yuan. And now less than a year the price has been nearly halved.
In the past, the high-speed solid-state hard disk was expensive, but now the 4T has directly reached the price range of 999 yuan.
Now the product prices are uneven. When you buy it, you must feel confused at first. With so many brands and such chaotic prices, how do you buy them?
This article will teach you how to choose and not step on the pit, because the price is cheap now, we mainly target high-end products, high-speed solid-state drives with a read and write speed of 7000MB/s, the specification is M.2, and the interface is PCIe 4.0.
This article has a lot of content, shopping guide, novice installation, actual measurement and so on. It is recommended to read it, it will be wonderful at the end, if you like it, please like and collect it.
The balance between brand and cost performance is shown in the picture above. This is a comparison between the current mainstream brands and domestic brands. It can be found that the current product speed is very fast, reaching a reading speed of more than 7000MB/s. Now the product price is very high. Low, more than 400 yuan for imported ones, and close to 300 yuan for domestic ones.
For other key information, follow me to analyze. 1TB SSD comparison:

Let's make a purchase recommendation first, and the domestic solid-state hard drive is the first choice. At present, there are 4TB solid-state hard drives available for purchase in China, and the speed is very good. Extremely cost-effective, recommend non-cache solid-state hard drives for daily office desktops, thin and light notebooks for capacity expansion, I recommend this one I bought first, the mobile speed storage Panther 4TB, the price is only 999 yuan, the price is very competitive.
Performance introduction: The price of this solid-state hard drive with a 4TB capacity has reached 999 yuan. This should be the first solid-state hard drive whose price has dropped to this price range. It adopts Maxio 1602U master control and domestic Changjiang TLC particle chip.
While others are 8000TBW, this one has obvious advantages when it comes to 9000TBW. The surface of the particles is encapsulated by shifting speed. Five-year warranty. There is no independent cache, but the cache space is about 32%, and the cache performance can reach more than 2600MB/s. You can see the actual measurement below.
Practical use: This is very suitable for the expansion of thin and light notebooks, business notebooks, or desktop hard drives with limited space, and PS5 expansion.
In addition, users of ultra-thin notebooks should pay attention when purchasing, and it is recommended to use Panther series solid-state drives for capacity expansion.
Because the panther series are single-sided particles, the cheetah series are double-sided particles. Particle introduction: Domestically produced TLC particle chips, graphene on the surface dissipates heat, and the temperature drops by at least 10°C.
Extreme performance, independent caching solid-state drive is recommended. If it is a gaming notebook or a gaming desktop, there is an extreme performance requirement for the transfer of a large number of small files, or if I do video editing, the files are often several gigabytes or more than ten gigabytes, it is recommended Buy a solid-state drive with competitive independent cache.
Or if I am doing video editing, the file size is often several G or over ten G. It is recommended to buy a competitive solid-state hard drive with independent cache, which has fast transmission speed, large write volume, and stability.
I bought this Cheetah 2TB with Changjiang granules, and 4TB with Magnesium or Changjiang granules mixed. It adopts Yingren master control, domestic Changjiang TLC particle chip, and the writing capacity is 9000TBW.
The 4TB independent cache has 4GB, and the price will be much more expensive, but it brings top performance.
Here is also some background knowledge, so you know how to choose. The recent dive of solid-state prices by solid-state storage particle manufacturers is mainly due to three reasons. Samsung and other major manufacturers have stockpiled goods since last year, and domestic manufacturers are mainly due to the rise of Yangtze River Storage, and then this time it happens to hit 618 again.
于是大家就感受到了一次固态硬盘价格的雪崩。 去年升级固态硬盘的小伙伴， 估计和我一样哭晕在厕所。目前市场上主流颗粒厂商是这几个， 如果想要选购固态硬盘， 那么你买的产品基本都是来自这六家公司的颗粒。
六大固态存储颗粒厂商分别是和他们2022年在全球固态存储颗粒的市场占有率， 这些数据来自网络。
其中排在末尾的就是来着中国的长江存储。 最近几年特别是高速存储颗粒方面， 长存的颗粒已经具有一定的市场号召力。
但是国产颗粒还是有随时被贸易制裁的风险， 所以建议大家有条件多支持国产产品， 这样才有机会以更低的价格购买到更快更好的产品。
另外固态还看下主控， 一线大厂预算足选择三星的主控。
如果是追求性价比， 可以考虑国产联芸主控。
寿命长， 写入量大， 基本可以达到进口产品的90%的性能， 但价格可能一半都不到。
品牌如何选择现在固态市场大跳水，各家厂商内卷严重，价格都降了许多，一些传统大厂， 和国产新兴产品品牌都非常不错， 用着放心，质保基本都是三年五年起， 能够走完你的电脑的完整生命周期， 不用担心数据出现问题。
目前市面上有这些品牌都是不错的。
固态硬盘品牌一线品牌：三星，西部数据二线品牌：镁光，海力士，铠侠，致态，金士顿三线品牌：移速存储，爱国者，梵想，金百达，微星
容量如何选择既然市场都跳水了，价格都降了，目前能够选择的有1TB到4TB之间， 512GB的就不要看了。
我建议，和我一样直接上4TB最好，性价比很高，后期也够用。 不然电脑没有多余的固态插口到时候也很麻烦。
你要升级等于过去的没用了， 白白浪费钱。 还一个就是这个价位固态颗粒目前是一个底部位置， 后续降价空间不会很大。虽然说普通办公的话512G也是足够的，但现在这个价格还是建议1TB起。
这么比起来， 我那个Mac电脑才256GB起， 真的是看不下去了。固态存储一般是容量越大， 速度越快， 能够支持的写入量TBW也越大。
固态容量越小就越影响性能发挥，所以尽量秉承着能买大就买大的原则。
固态硬盘接口和尺寸选择常见的固态硬盘接口有SATA接口、M.2接口和PCI接口。目前大部分比较常见的产品，使用的都是M.2接口和SATA接口。
固态的尺寸： 一般现在买的M.2的固态硬盘， 尺寸都是2280， 也就是宽22mm，长80mm。SATA硬盘通常是2.5寸，一个小盒子， 这个很容易区分。
举个例子， 这个是东芝的一个产品规划， 也可以看到M.2 2280的接口，大概在整个产品线中的什么位置。
M. 2接口：速度快，性价比高，传输效率高，接口少。 台式机小主板可能就一个插口， 标准板子可能有两个插口。 笔记本一般一个， 有些游戏本支持两个扩容。 而且， M.2接口只有M key接口类型才是高速的，另外的B key和B&M Key接口速度和SATA接口没差多少。
SATA接口：速度慢，但是便携性好拓展性好，更安全。
小结如果是第一次组装，或者是给现在的机器扩容， 先看下自己电脑设备上的接口。 根据自己电脑或者其他设备上的接口选择相对应的固态类型，买错了就会出现接口插不上去， 不能使用的情况，或者是能插上去但是读写速度降了下来， 白白浪费钱。
PCIe 3.0和PCIe 4.0选择哪个？先回答， PCIe4.0和m.2的区别。 PCIe4.0和M.2是两个完全不同的东西。
M.2上面说了这是一种接口。 而PCIe4.0是一种数据传输协议， 高速串行计算机扩展总线标准。PCIe后面跟的数字， 表示几代的协议。
代的数值越高， 表示所支持的传输速率和带宽更高。
目前， 建议大家购买PCIe4.0协议的固态， 理论峰值可以达到8000MB/s的读取速度。PCIe3.0理论峰值可以达到4000MB/s的读取速度。
PCIe5.0理论峰值可以达到16000MB/s的读取速度。而前面说的SATA接口， 理论峰值仅仅为600MB/s。 虽然说， 现实中的速度还是得看固态硬盘自己的实际电脑配置情况， 但峰值就是一个分水岭。
举个例子， 无论是PCIe 3.0还是PCIe 4.0， 都可以安装在电脑上M.2接口。 安装在电脑上后， 必须是要有其他硬件的相互支持。 比如， 如果主板仅支持PCIe 3.0，但是你安装了PCIe 4.0的固态，有的固态会向下兼容，自动降速，还能使用。
反之， 就不行。另外， 虽然说PCIe5.0的速度更快， 但现在价格太高， 而且能够支持的主板，CPU相应都更加贵， 成本上划不来。小结在固态硬盘都是M.2接口的情况下， 建议购买PCIe 4.0接口。
PCIe 3.0便宜，性价比高，发热低。PCIe 4.0速度快，发热高，台式机预算够无脑入PCIe 4.0，笔记本则根据电脑支持哪种传输规格， 电脑散热和性能来选择。
如何安装M.2固态硬盘？ 新手教程先将主板上固态位的螺丝取下来，一般都会有。
然后倾斜固态硬盘， 并且对准接口凹槽位置推进去。 一定要注意接口凹槽， 固态接口位置形状位置全部一致， 不要插反了。
然后轻轻把固态放下，把尾部的豁口对准螺丝柱的位置，然后装上螺丝即可，不用拧的太紧。要保持固态和主板是平行的状态，这样是正确安装的状态， 其他都是不行的， 安装错误不要开机， 不然容易对固态造成伤害！
读写速度， 4TB无缓存固态硬盘测试在TxBENCH下的速度测试， 读速高达7163MB/s, 写入速度达到6682MB/s, 和我现在的MacBook Pro 14的笔记本相比都要更快。 MBP的速度也仅仅达到5000MB/s左右。
我们在AIDA64下的硬盘读取测试速度， 全程6200MB/s非常稳定。
连续读写速度连续读写速度决定大文件的读写速度，一般用作文件传输，备份，拷贝等。一般产品宣传中写的读写速度就是这个，也叫做缓内读写速度，缓内读写速度降速后就变成了缓外读写速度。
目前这个级别的存储颗粒都可以达到7400MB/s的速度， 日常电脑使用， 感受会觉的非常非常快。 缓内速度可以到5320MB/s。
4K随机读写速度随机读写速度决定了一些小文件的读写速度，一般影响系统的载入，用作系统盘的话一定要快！打游戏也是，不然跟不上队友。日常使用的固态的速度，随机读写在现实中的差别并不是特别大。
这个在固态硬盘里面主要看缓存， 有些配置了缓存的4K随机读写速度会更快。比如下面这款。CrystalDiskMarkCrystalDiskMark(硬盘检测工具)， 这个是一个经常使用的硬盘性能测试工具。
一般可以测试最大顺序读写速度、深度队列读写速度、4K小文件随机读写速度等参数。选择标准设置即可。
CDM测试结果：
● 有缓固态在整体性能上还是优于无缓固态。 一分钱确实一分货！
● 无缓固态性价比高，差距没有那么大， 价格优势明显。
小Tips传输大文件连续读写速度很重要， 小文件多随机读写速度重要。
日常使用普通版本高速固态即可， 如果打游戏多买带缓存的高速固态硬盘。
一般1TB固态带缓存1GB， 2TB固态带缓存2GB， 依次类推。 我这里4TB带缓存和不带缓存差价400多元， 差距还是很多的， 所以选购的时候主要看自己用途。
温度因为本次测试是在台式机上进行，散热是表面贴的石墨烯贴纸， 在测试过程中， 室温26℃，多次测试， 实际测试硬盘表面温度最热的时候， 温度也不会超过50℃， 可以看出温度控制确实不错， 日常使用毫无压力。
PS5固态扩容现在的PS5一直都是标配的容量， 大概650GB左右。
我购买了几年的会员， 最近一直有活动， 下载了几个之前限量的游戏， 但很快问题就来了， 装几个游戏就要删除。 只能装了这个游戏， 就要删除那个游戏， 这个操作就那个就很烦。
我刚买的时候PS5的PCIe 4.0规格的固态硬盘1TB的要1000多， 现在无脑直接上4TB， 绝对的不容错过的扩容好时机， 确实真香体验了。
PS5扩容需要注意
● PS5只能使用M.2接口PCIe4.0速率的固态硬盘。
● 固态硬盘要求顺序读取与写入速度都超过5500MB/s，以前因为贵会有顾虑， 现在基本不用考虑了， 直接上高速的固态硬盘。
● It is recommended to add a heat sink for the PS5 solid-state drive. When purchasing, you can directly consider a solid-state drive with a heat sink, and the price will be slightly higher. If the budget is insufficient, you can install TB yourself or buy a heat sink and install it yourself, usually around 20 yuan. After installation, the width should not exceed 25mm, and the total thickness should not exceed 11.25mm.
● There is also graphene heat dissipation now. For example, the three solid-state models I chose are graphene stickers for heat dissipation.
The SSDs I selected earlier have a sequential read speed of 7450MB/s and a sequential write speed of 6500MB/s, and there is no problem with performance data.
2 minutes PS5 expansion hard drive installation steps Open the cover, place it at this angle, with the optical drive seat facing you, lift the upper left corner of your left hand slightly upwards, hold the cover with your right hand and pull it to the right, it is easy to take it off. If you don't know how to leave a message in the comment area, I will teach you.
Open the hard disk cover, install the hard disk, I don't have a heat sink;
Close the cover, turn on the computer, and format the hard disk. Here, the speed of the 4TB hard drive tested by PS5 is 6536MB/s, which is far higher than the speed of the original PS5 hard drive. PS5 requires 5000MB/s, which can fully meet your needs for any game.
Enter the storage settings, set to install the game in the hard disk, or move the game installed in the fuselage before.
Now there is 4TB of space, the game is playing smoothly, and there is no space anxiety. And I can give full play to the rights of purchasing a PS membership. I have installed 100 games and can play slowly.
To sum up, this article basically sorts out all the knowledge points for purchasing solid-state drives. It is large and comprehensive, and it is also easy to understand. If you still have any questions about purchasing solid-state drives, just leave me a message in the comment area, and I will answer. Now the price is really good, and there will be a big promotion later, it is recommended to start without thinking, now it is a god price from time to time. For example, this 4TB solid-state hard drive has been flashed to 999 yuan, so let’s just squat at 20:00 on the 6th.
If you have game needs and have requirements for extreme performance, then choose a product with cache, which is also very cost-effective. It is very cost-effective to start now, and it provides a long-term warranty, and the quality is enough to make people feel at ease.
