[Testing] Solid State Drive for the Kingston KC400 corporate segment with a capacity of 512 gigabytes
Hi, Giktayms! I continue a pleasant tradition: in January after the CES 2016 exhibition there was an announcement of the Kingston KC 400 drive, and literally one and a half months later, a post about testing this SSD disk was published on the GeekTimes blog. For familiarization with the novelty I ask for cat.
Kingston SSD packaging is quite traditional and does not contain additional expensive decorative elements. A cardboard blister with a transparent plastic insert does not contain anything extra and additional, even a plastic frame to increase the height of the disc to 9.5 mm.

Kingston KC400 is built on an eight-channel Phison PS3110-S10-X controller. This is the most advanced option from the current range of the manufacturer. Option familiar to most modern SSD Kingston.
The memory is recruited by 16 MLC chips under the Kingston label with the FD32808UCT1-DE label, with a capacity of 32 gigabytes each. Thus, the total disk capacity is 512 gigabytes, of which not the entire volume is available to the user, but only 477 gigabytes, the rest is reserved for the backup area.
The 128 MB cache is organized by the Nanya NT5CC128M16FP-DI microcircuit.
Official disk specifications assume the speed of work with sequential reading / writing at 550/530 MB / s; when working with random 4K blocks, up to 86000/88000 IOPS.
The TBW parameter, which determines the maximum amount of information that can be written to a disk, is set at 150 terabytes for a disk with a capacity of 128 gigabytes, for disks 256, 512 and 1024 gigabytes, it is 300, 800 and 1600 terabytes, respectively.
The testing method is quite simple:
Before the tests, a volume of information twice the disk capacity is recorded on the disk, after each test a pause of half an hour is made for the TRIM command to work correctly.
Synthetic test to assess the correctness of the speeds declared by the manufacturer. Actually, most of the data indicated on SSD drives of different manufacturers is obtained using the ATTO Disk Benchmark.
This test allows you to evaluate the drive in four modes: linear read / write, read / write blocks in 4K, linear read / write at a queue depth of 32 commands, read / write blocks in 4K at a queue depth of 32 commands.
The most advanced of the tests. I will conduct several test options:
In the test package PC Mark 8 there is an opportunity to conduct performance recovery tests with long-term load.
The package operation scheme is as follows:
First, the disk (unformatted, without partitions) is filled twice in blocks of 128 KB each.
Then the degradation phase follows:
The disk is filled with random blocks of different sizes from 4 KB to 1 MB. Since the blocks are not aligned, disk performance drops dramatically.
The first tests begin 10 minutes after the disk is filled with random blocks.
After passing the test, the filling process is repeated. Before each new test a pause is made that is five minutes longer than the previous one, that is, 15 minutes, 20 minutes, and so on. This is repeated eight times.
After this, tests of the stable phase begin. The script is repeated five times, a pause of 5 minutes is made between runs without additional load being applied.
This is followed by the performance recovery phase, when a five-minute pause is made between the scripts to complete the disk cleanup.
The package is testing several applications, I chose Adobe Photoshop (heavy script).
I give four graphics: average access time, read speed, write speed, total disk speed.
It is very clearly seen how the recording speed and access time is restored as the disc “rests”.
Kingston KC400 confidently shows itself in most tests, which certainly leaves a pleasant impression. Significant indicators on recording volumes allow us to consider this solid-state drive as a reliable basis for systems with frequent use of write operations.
The average price of Yandex.Market for a model with a capacity of 512 gigabytes at the time of publication is 15,136 rubles .
