Kingston is rapidly updating the range of SSD drives, quickly introducing fresh controllers and NAND memory. It is brilliant in the segment of budget models, where no serious requirements are imposed on the drive in terms of speed and endurance. An update has arrived – the NV1 model. Let’s see it in action.

Appearance & Design features
Kingston has completely switched to cardboard blisters with a plastic insert. The decision is justified, especially in the public sector: why spend an already small budget on the packaging. A well-formed plastic is strong enough to protect the electronics from mechanical damage.
Unpacked SSD Standard: M.2 2280 format
The microcircuits are soldered only on the front side of the board, so the total thickness of the SSD is just over 2 mm. No wonder the manufacturer positions it for mobile devices, where space for a drive is limited.
There are five microcircuits under the sticker: a controller and four with NAND memory.
Controller marking PS5013-E13-31. This is an inexpensive solution from Phison for budget NVMe drives. It is not equipped with a buffer but uses part of the RAM for storing service information (HBM technology, Host Memory Buffer). Since the controller “communicates” with the processor via four PCI Express 3.0 lanes, the interface bandwidth is enough to provide decent performance – up to 2500/2100 MB/s (streaming read and write, respectively). It is noteworthy that Kingston itself claims 2100/1700 MB/s for the terabyte version of NV1. Reassurance? If so, then this is even for the best. There is no longer a need to chase peaks in the user sector. Stable performance and low cost are the keys to success.
The controller works with 3D memory. The NV1 contains 4 microcircuits with a total volume of 1 TB. A little more than 931 “honest” gigabytes are available to the user.
General data on the drive and supported technologies can be viewed in two screenshots:
The CrystalDiskMark benchmark shows the manufacturer’s stated numbers: streaming read and write 2008 and 1753 MB/s, respectively. The drive also copes well with random reads and writes.
A more “down-to-earth” estimate of the speed of AS SSD drives show the numbers much lower: 1765 and 1435 MB/s, and the speed for random read operations of a 4K block falls below 50 at all. 498 MB/s with small files up to 921 MB/s with large files.
The controller’s abilities under significant loads are well shown by the test utility from the AIDA64 program. With streaming reading, everything is perfect: stable 2765 MB/s with a single drawdown of up to 2374. This is even more than the controller manufacturer claims. With recording, not everything is so rosy: up to 27% of the volume (a little over 250 GB) 1600 MB/sec, after a failure to a couple of dozen, when the controller is no longer able to write data and deal with their “structuring simultaneously.” However, you need to consider that the model is budgetary, and there will be no real tasks on an ordinary PC or laptop.
Random read and write graphs are not bad: 763 and 209 MB/s, respectively. These are averaged readings. In reality, when recording, the controller periodically briefly gave up to 937 MB/s but quickly returned to “somewhere around fifty.” The reasons are the same as with linear recording: the controller is not suited for such tasks.
The drive heats less than 40 degrees during operation with a passive radiator. This is an excellent indicator, especially considering that the temperature jumped by only 3 degrees during active recording – from 36 to 39 Celsius. Under normal “household” load, it can be used without a radiator at all.
Let’s sum up
Kingston NV1 is one of the few fast and relatively inexpensive storage media installed in devices without serious heat dissipation systems. It is well suited for thin laptops, “carriers,” nettops, small-sized SoC-based systems (for example, a pocket file server on RasberryPI). The price for the terabyte version is $150, which is quite a bit (for comparison: some 970 EVO of the same volume will cost one and a half times more).
- Low heat dissipation and power consumption;
- Hardware encryption AES 256;
- Large area of ”fast” streaming recording.
- Random write speed.
