Which is better for a 240 256g SSD

When buying an SSD, you have to choose according to your needs.

1. Pursue compatibility and longevity: If it is an upgrade of the old book, compatibility is particularly important. Because there are quite a lot of compatibility problems with SSDs. For good compatibility and long life, choose Intel and Kingston.

Intel's 530 and 520 performance is very scum, the only advantage is that it has a long life and good compatibility, it is better for small businesses to use, and it is a bit slow for home use, it is best to choose 730, which is almost an overclocked version of enterprise-level S3500, the main control is over 50%, and the performance is directly chasing S3700, but it is much cheaper, very durable, and has both performance and compatibility.

Kingston's V300 series is the lowest level of reliable and long-life SSDs, less than 300 yuan.

2. The pursuit of cost performance: Solid-state drives have been used for a long time, and the speed is generally more severe, but some main control mechanisms are good, so they don't slow down much. The speed drop on the market is not obvious, and the following models have the best cost performance and reputation:

Puket M6S, SanDisk Extreme High-Speed Series 1st generation (2nd generation has changed to TLC, the speed is the same, the life is shorter), Samsung 850EVO, Micron M550 or or 128G, most of them are less than 400. Some are already close to 300.

Intel 730 Series 240G

Samsung 850Pro Series 256g

240G SSD To be honest, there is really no need to buy thousands, Intel Samsung just looks at faith, you can really start, and there are only three of them.

Pukot M6S series 256G

Critical MX200 Series 250G

Toshiba Q200EX series 240g

No matter how low it is, push SanDisk X110, which is invincible in cost performance, TB 256G

As can be seen from the above information, the storage capacity of hard disks is different.

The difference between a 240G SSD and a 256G SSD is that the meaning is different, and the memory is different.

First, the meaning is different: 240g manufacturers are calculated by 1m = 1000kb, and the computer system is calculated by 1m = 1024kb, and the actual capacity installed in the computer is. Similarly, a 256g solid-state installation on a computer has a capacity of .

Therefore, there is only a difference in capacity between the two, and there is no substantial difference in performance between the same particle solid, and it is recommended to install a solid state with a capacity of 256g.

Second, the memory is different: 240SSD: It is a storage capacity of 240G, but there is only memory. 256SSD: It is a storage capacity of 256G, but it only has memory.

Flash-based SSDs:

Flash-based solid-state drives (IDEflash disk, Serial ATA flash disk): use flash chips as the storage medium, which is also commonly known as SSD. Its appearance can be crafted in a variety of shapes, such as:

Laptop hard drives, micro hard drives, memory cards, USB flash drives, etc. The biggest advantage of this SSD is that it can be moved, and the data protection is not controlled by the power supply, it can be adapted to various environments, and it is suitable for individual users.

This capacity is not common in the mainstream market this year,Starting from the practical experience,Installing a win10 system will take up about 30-40G space,And virtual memory、Various caches also need to occupy space。 There will be little space left for program installation and file storage, and the cache will continue to grow in the future. Therefore, at present, a 128GB SSD is absolutely unavailable, and even the simplest office cannot be used comfortably.

GBThe capacity is relatively suitable for medium and light office users, daily office, ****, chat, etc., 256GB is basically enough. If there are too many files, you can also consider buying a network disk to cooperate with storage in the future. In short, for light office and normal users, there is absolutely no problem with a 256g SSD.

GB, this capacity is currently the most mainstream capacity specification, and I personally think that the cost performance is better. Whether it is office, entertainment, or game storage needs, it can basically be satisfied. The ** of about 500 is also relatively reasonable, and if you use it lightly, it will not cause too much waste of space.

Theoretically, the larger the space of the SSD, the faster the read and write speed, and putting all the games in the SSD can also speed up the read and write speed of the game. In addition, if you are a content creator and need to store a large number of **, ** and other materials and materials, you need more than 1t of hard disk space.

Whether it is a 256G SSD or a 500G HDD, there is no problem with normal use for 3 years.

The lifetime of an SSD is related to the number of times it is erased and written, i.e. p e. A 256G SSD needs to write a 256G file to be counted as a PE, and the TLC, which has the shortest lifespan, also has 1000 PE times, and it takes 10 years to exhaust its lifespan.

The service life of a hard disk is related to the wear and tear of the head. After the verification of the majority of computer users, a qualified mechanical hard disk can be used for more than 10 years, so there is no problem with a 500g mechanical hard disk for 3 years.

The differences between 256G solid-state and 500G HDDs are as follows:

1. Read/write speed.

Solid state drive: using flash memory as the storage medium, there are no mechanical parts, and the seek time is almost 0, so the read and write speed is relatively fast;

Mechanical hard disk: The internal mechanical parts rotate at high speed, there is a seek time, and the speed is slow.

2. Shockproof and drop resistance.

SSD: No mechanical parts, no impact on data in case of accidental vibration;

Mechanical hard disk: It requires high-speed operation of the robotic arm during work, which has poor stability, and is easy to be damaged and lose data in case of vibration.

3. Power consumption and noise are different.

SSDs: low power consumption and noise;

HDD: Because of the presence of mechanical parts, the power consumption and noise are higher than that of solid state.

4. Operating temperature range.

SSD: The chip has a wide operating temperature range (-40 to 85 degrees Celsius);

HDD: Can only work in the range of 5 to 55 degrees Celsius.

5. The weight and volume are different.

SSDs: small and lightweight;

Mechanical hard drives: very heavy and not easy to carry.

The difference in capacity is clear at a glance, and the difference in performance is much faster than that of 500g machinery.

If you use it normally, the capacity requirements are not too high. There aren't a lot of movies. The 256g solid state is highly recommended.

It's a lot faster. Three years later, the mechanical hard disks on computers were basically obsolete. It's all solid.

An SSD labeled 256GB is the same as an SSD labeled 240GB, there is no difference. The missing 16GB capacity does exist because all storage products, including SSDs, use binary storage.

Therefore, the capacity value is a power of 2. For example, 128GB GB (2 9), and because of this, the difference between the two adjacent capacities is doubled.

If the nominal capacity of an SSD is 2 times 10,000, then it is called a full capacity. If the nominal capacity of an SSD is not to the power of 2, such as 120GB, 240GB, 480GB, then it is called insufficient capacity, and the insufficient capacity of the SSD does not follow binary storage, but part of the capacity is allocated to the reserved space to improve performance.

The 256G capacity is basically MLC flash SSD, such as the Toshiba Q300 Pro is this category, and the flagship model with a 5-year warranty. TLC SSDs, on the other hand, generally need to reserve some additional OP space to optimize performance and durability, such as Toshiba A100 and Q300, which are cheap and enough for home use.

240 is the nominal 256, 256 is 1000m1g, 240 is 1024m1g
