With the development of storage technology and the continuous improvement of main control performance, it is routine for high-end solid-state drives on the market to run at PCIe3.0x4 speed. Due to the limitation of protocol bandwidth, the speed of high-end solid-state drives is difficult to match the mainstream series. To widen the gap, if major storage manufacturers want to further improve hard drive performance and segment market categories, they can only wait for the birth of a new bus protocol.

When solid-state speed fell into a development bottleneck, the new PCIe.0 bus protocol was born. Motherboard and hard disk main control manufacturers have fully supported the new protocol. As the saying goes, everything is ready, all we need is Dongfeng, and major manufacturers are looking forward to it. The long-running hard drive speed competition has begun again, with Gen4 solid-state drives popping up like mushrooms after a spring rain. Aigo, a well-known brand that has been deeply involved in the storage market for many years, has also followed this racing trend and launched the aigoP7000 solid-state drive. The

PConline evaluation room also received this hard drive at the first time. The official claims that the sequential read and write speed of the 1TB version can reach 7000MB/s and 5500MB/s. In addition, there is also a larger capacity 2TB version to choose from, with the sequential read and write speed of Reaching 7000MB/s and 6850MB/s, the performance is very fast from the parameters, but what is the actual performance? Let’s take a look next. The hard drive received in the

evaluation room is a 1TB capacity version. On the front of the package, you can see that the hard drive supports lifetime maintenance and a 3-year warranty. However, when I checked the parameters on the e-commerce platform, I found that this hard drive has a 5-year warranty or a 700TBW write capacity. For consumers, the longer the warranty period, the more peace of mind they will feel. The back of the

package comes with a product description and product anti-counterfeiting logo. The hard drive body can be seen in the "small window" in the middle. The label on the

hard disk body is attached with the product SN code, barcode and certification mark. The

packaging box only contains the hard drive body and fixing screws, and does not come with a cooling vest. However, motherboards and M.2 armor are basically standard now, so you don’t have to worry too much about temperature issues. The

aigoP70001TB solid state drive has standard M.22280 specifications and uses a single-sided particle design, with four NAND particles + one DRAM cache particle. However, you can see that four NAND pads and one DRAM pad are reserved on the back. Therefore, the 2TB version should be designed using eight double-sided particles + two DRAM cache particles.

After peeling off the sticker, the hard drive main control, DRAM, and power management chip are right in front of you. The

aigoP70001TB solid-state drive uses Phison's flagship main control chip PS5018-E18. It will be produced in the 14th week of 2021. It is manufactured using the TSMC2nm process. It is equipped with a three-core Cortex-R5 CPU and supports the PCIeGen4x4 protocol (backwards compatible) and the NVMe1.4 specification. It supports up to 8TB capacity, and the DRAM controller supports DDR4 cache particles. The highest sequential read and write performance of the master can reach 7400MB/s and 7000MB/s. Compared with the first generation PCIe4.0 master PS5018-E16, the performance has been greatly improved. The power management chip next to the

main control is also from Phison, with the model number PS6108-22. Below the

master control is the DRAM cache, from SK Hynix , model H5AN8G6NCJ-RVKC, DDR41333Mhz, capacity 1GB. The

NAND particles are self-proclaimed particles by Phison. The particle number is IA7BG64AIA. However, the relevant information of the particles can be obtained using the Flash_ID software: TLC particles from Micron . Four NAND particles with a capacity of 256GB form a 1TB capacity. The test platform used in the

reading and writing performance test

evaluation is that the motherboard is ASUS ROGSTRIXZ590-AGAMINGWIFI, the CPU is i9-11900K, the memory is Zhiqi Royal Halberd RGBDDR4-4000C14, the system disk is Samsung 970EVOPLUS1TB, and the test disk is aigoP70001TB solid state drive. The test Thermal paste and heat dissipation vest are covered during the process.

First, take a look at the actual available space of this hard disk. You can see that the available space displayed in the system reaches 931.50GB, which is within the normal capacity range of a 1TB hard disk.

uses the hard disk health detection tool CrystalDiskInfo to view the hard disk information. We see that the firmware version of the aigoP70001TB solid state drive is EIFM21.2, the transmission mode is PCIe4.0x4, supports the NVMe1.4 standard, supports S.M.A.R.T, TRIM and VolatileWriteCache functions, and the standby temperature is 35 degrees.

When the disk is empty, use CrystalDiskMark test software to perform the default read and write speed test on the hard disk. In the 1GB test, the SeqQ8T1 sequential read speed was 7043.93MB/s, and the sequential write speed was 5482.72MB/s. In the 16GB test, the SeqQ8T1 sequential read speed was 7044.48MB/s, and the sequential write speed was 7044.48MB/s. 5319.84MB/s, the reading and writing performance is basically in line with the official nominal level.

used ASSSD software to conduct a 1GB read and write speed test. The 4K multi-threaded read IOPS score of the aigoP70001TB solid state drive was 506901, and the write IOPS score was 1234433. In the 10GB large file read and write test, the 4K multi-threaded read IOPS score was 325525. , the write IOPS score was 780524, and the hard drive performed amazingly in terms of writing speed.

uses TxBENCH to perform the SLCCache cache test on the hard disk. It can be seen that the write cache is out when about 100GB. The 100GB SLC cache is sufficient for daily use. The writing speed of

before leaving the cache exceeds 5500mB/s, and the speed has almost no fluctuation. After leaving the cache, the writing speed is first around 1100mB/s. When the writing volume reaches 775GB, the writing speed is between 650mB/s and 850mB/s. fluctuate between.

After a series of empty disk tests, we can see that the aigoP70001TB solid-state drive has been very fast in reading and writing performance due to its powerful main control strength. So what is the performance in half-disk state?

uses the CrystalDiskMark test software to conduct a speed test on the hard disk when the hard disk uses 51% of its capacity. In the 1GB read and write test, the SeqQ8T1 read speed was 6728.10MB/s and the write speed was 5314.34MB/s. In the 16GB read and write test, the SeqQ8T1 read speed was 7044.53MB/s and the write speed was 5309.11MB/s. s, there was no serious slowdown in half of the disk, and it maintained excellent reading and writing performance.

After a series of tests at room temperature of 25 degrees, the highest temperature area on the surface of the motherboard armor covered by the aigoP70001TB solid-state drive was 53 degrees. When the heat dissipation armor was used in addition, even in the state of continuous reading and writing, the hard drive did not Will cause the temperature to be too high and slow down.

Evaluation Summary

With the full popularity of the PCIe4.0 protocol, the read and write speed of solid-state drives has been raised to a new level. For example, the aigoP70001TB solid-state drive in this review is supported by the flagship Phison PS5018-E18 main control Next, the sequential read speed has reached 7000MB/s, and the sequential write speed has also reached nearly 5500MB/s. Both results have reached the PCIeGen4 speed level.

In addition, this hard drive also has a high-quality warranty of 5 years or 700TBW writing. With the help of a heat sink, it can also have good temperature control to ensure the stability of daily use. It is a great purchase for gamers or creators. A premium choice for capacity Gen4 SSDs.
