As an electronic expert, according to my own experience in purchasing and using, I sorted out five high-cost products that I have used SSD myself and recommended them to you: Samsung SSD 750 EVO, Toshiba Q300, OCZ) Trion, Inch Armored Warrior Series and Kingston UV400.
Look at the relevant information with me ~
I. Samsung SSD 750 EVO 250G

Third, The Hungry Shark (OCZ) Trio
Effect rating star: ★★★★? ★
Reference price: 599 yuan
Recommended reason:
Solid-state hard disks are updated quickly, and various brands and models are constantly being refurbished. Today, I recommend an OCZ Trion 150 made by hungry sharks. This SSD adopts Toshiba 15nm TLC flash memory chip, which optimizes the firmware of the main control chip, enables the latest visual design of the product appearance, and is more vivid and stereoscopic, in line with the recent market trend of e-sports and DIY upgrade. Now the price in JD.COM is 599 yuan.
OCZ Trion 150 240GB SSD is equipped with independent cache, and 6.25% secondary OP redundant cache is reserved to improve service life and performance. So this SSD is equipped with a flash memory with a capacity of 256GB, and the available flash memory capacity is 240GB. OCZ Trion 150 240GB SSD is a 2.5-inch standard with a thickness of 7mm, which supports the Trim garbage collection mechanism. Support SATA3.0 6Gbps rate interface (compatible with SATA2.0 interface), suitable for upgrading ultrabooks, thin notebooks and desktop computers!
4. Yingchi Armored Warrior Series?
Effect rating star: ★★★★? ★
Reference price: 499 yuan
Recommended reason:
Inch Armor Warrior Series 240G 2.5 inch SATA 3SSD JD.COM price 499 yuan >> Buy link.
Galaxy insists on and advocates the industry's sincere "three-year replacement" service. If the user's SSD fails, it can "wait" to replace it. This is Galaxy's emphasis on users and confidence in its own products. Infineon SSD has a very good performance in durability test. In the ultra-long test of 150 days, a single disk has written a huge amount of data of 9 14T, which passed the power-off test perfectly, equivalent to the normal use of ordinary users for more than 450 years.
Five, Kingston UV400
Effect rating star: ★★★★? ★
Reference price: 5 19 yuan.
Recommended reason:
20 16, more and more SSD manufacturers choose to use TLC flash memory. Although the theoretical life is not as good as MLC, TLC flash SSD is becoming the choice of more and more people because of its low price, especially MLC's incomparable advantages for large-capacity products of 240GB and above.
Kingston launched a new SSDNow UV400 series SSD for the entry-level consumer market, with a standard 2.5-inch specification of 7 mm thickness, Marvell 88SS 1074 main control chip, four channels, TLC flash memory, idle power consumption of 0.59W, average 0.672W, maximum 0.693W, maximum reading time of 2.72W, and writing and storage temperature of-40℃ ~ 85.
Tips:
1. Don't use Disk Utility to "organize" the SSD. Solid state hard disk is different from mechanical hard disk. When reading and writing mechanical hard disk, too many fragments will affect the performance and need to be sorted. Solid state drives are not, and defragmentation is not effective for solid state drives.
2. Don't use performance testing tools too much. The performance of SSD is much stronger than that of mechanical HDD. It is common for players to run tests and take screenshots. This will cause greater read and write losses to SSD and accelerate the speed of performance degradation.
3. Pay attention to turn on "Trim". The role of Trim is to optimize SSD reasonably and reduce the speed of its performance degradation.
4. Select high-performance power mode. Energy-saving not only saves power, but also begins to decline in performance, which also has such an impact on solid-state hard disks.
