After entering the NVMe SSD market with Crucial P1 in 2018 , Micron's expansion in these products has not been as fast as Chen Ba imagined. Even as a major manufacturer of AQV217 memory particles, Micron has only launched P2 and P5 this year. Two products aimed at different orientations are aimed at entry-level groups (P2) and applications such as editing, design, gaming and multitasking that require high-speed access (P5). Chen Ba also received the Crucial P5 test product before. Let's see if Crucial P5 can win favor with performance in the competitive SSD market.

The flash memory particles of Micron Crucical P5 1TB SSD use its own MW969 3D NAND particles, with two 512GB configuration.

The memory part uses Micron's own D9ZCM LPDDR4-4266 DRAM, and the 1TB version uses a 1GB capacity configuration.

The controller part adopts Micron's own DM01B2 controller, which provides 8 flash memory channels and PCIe 3.0 x4 NVMe interface support.

In addition, in the TBW lifetime write volume section, the Micron Crucial 1TB version has a lifetime total write volume of 600 TBW.

◆Micron Crucial P5 CrystalDiskMark test

Using CrystalDiskMark to test the actual access speed of Micron Crucial P5 SSD 1TB, the result of sequential reading is 3482.89 MB/s, and the product of sequential writing is 3256.09 MB/s. In the part of random write depth 1 in 4K small blocks, read The fetch speed is 53.56 MB/s and the write speed is 127.68 MB/s. The performance in this part is in line with Micron's official figures.

◆Micron Crucial P5 ATTO Disk BenchMark test

In the ATTO Disk BenchMark test, Micron Crucial P5 SSD 1TB has a reading performance of 3.05 GB/s in blocks above 64 KB (inclusive), and 3.23 GB/s when writing blocks above 4MB the high peak.

Read and write IO has the best performance in 4KB blocks.

◆Micron Crucial P5 AS SSD Benchmark test

In the AS SSD Benchmark section, the Micron Crucial P5 1TB SSD got a total score of 5242. Under the 1GB test file setting, the sequential read and write scores were: read 2899.89 MB/s, write 2648.24 MB/s. The results of the random access IO part are 377429 iops for read and 543060 iops for write in the 4K 64-Third part.

◆Micron Crucial P5 TxBench test

In the TxBench test, the Micron Crucial P5 SSD 1TB achieved a sequential read of 3454.528 MB/s and a write of 3217.439 MB/s, while the 4K random read and write QD1 achieved a read score of 52.762 mB/s and a write of 127.350 mB /s.

◆Comparison of test data of three PCIe 3.0 SSDs

In the horizontal evaluation part, Chen Pulled out the performance of the previous test Samsung 970 Pro and Kingston KC2500 1TB for comparison. The following are the test comparison results of the three SSDs:

◆Micron Crucial P5 SSD 1TB PCMark 10 actual performance test

Then use the storage device test items in PCMark 10 to test the Micron Crucial P5 SSD 1TB, including the Full SYSTEM Drive Benchmark of the whole system, the Data Drive Benchmark used as a data disk, and the Drive Performance Consistency test three of the read and write performance of a large amount of data. a test.

Taking Micron Crucial P5 SSD 1TB as the whole machine disk, it is tested with Full SYSTEM Drive Benchmark, the test score is 1944, the bandwidth is 313.77 MB/s, and the average access time is 87 ?s.

Using the Micron Crucial P5 SSD 1TB as a data access disk, the result of the test with the Data Drive Benchmark function, the score is 2418, the bandwidth is 368.14 MB/s, and the average access time is 66 µs.

In addition, in the Drive Performance Consistency test, which is used to measure the durability of a large number of, long-term, 2-3 full-disk reads and writes, the Micron Crucial P5 obtained a score of 736, a bandwidth of 177.20 MB/s, and an average storage capacity of 177.20 MB/s.

Chen Ba also compared the data of the previously tested Smasung 970 Pro and Kingston KC2500 SSDs in the Drive Performance Consistency test. The results are as follows:

In the endurance test of Micron Crucial P5 SSD, the decay rate is a little faster than the other two products, mainly because the temperature easily rises above 70 ℃ and the overheat protection mechanism is activated. It is recommended to use Micron Crucial P5 SSD. It is necessary to pay more attention to its heat dissipation method, and the installation of external heat sinks will be a better way to use it.

●Micron Crucial P5 1TB SSD test conclusion

For Micron, which has not entered the SSD field with its own brand for a long time, the cost-effective MX500 in SATA products has won many praises from consumers, and the P series of the NVMe product line has also achieved quite good performance in the P5 series this time. Not only large-capacity products above 1 TB have such a read and write speed, but also the 500GB-level version, which is one of the few products with high-speed read and write capabilities among small-capacity SSD products.

In addition, Micron Crucial P5 SSD has a number of functional protection designs that are difficult to see in other products. Although it has a low score in the endurance test of long-term continuous reading and writing, it provides a certain degree of data security protection. , For applications such as image creation, editing, and design where the security of work data is relatively important, the Micron Crucial P5 SSD may be a choice worth considering.
