Posted 17th Sep
Product Description
Kingston’s A400 solid-state drive dramatically improves the responsiveness of your existing system with incredible boot, loading and transfer times compared to mechanical hard drives. Powered by a latest-gen controller for read and write speeds of up to 500 MB/s and 450 MB/s¹, this SSD is 10x faster than a traditional hard drive² for higher performance, ultra-responsive multi-tasking and an overall faster system. Also more reliable and durable than a hard drive, A400 is built with Flash memory. There are no moving parts, making it less likely to fail than a mechanical hard drive. It is also cooler and quieter and its shock and vibration resistance makes it ideal for notebooks and other mobile computing devices.

A400 is available in multiple drive form factors and capacities from 120 GB–1.92 TB² to give you all the space you need for applications, videos, photos and other important documents. You can also replace your hard drive or a smaller SSD with a drive big enough to hold all your files. This SSD is designed for use in desktop and notebook computer workloads and is not intended for server environments. 1.Some of the listed capacity on a flash storage device is used for formatting and other functions and thus is not available for data storage.

As such, the actual available capacity for data storage is less than what is listed on the products. 2.Based on out-of-box performance using a SATA Rev. 3.0 motherboard. Speed may vary due to host hardware, software and usage. IOMETER Random 4k Random Read/Write is based on 8 GB partition.

Good price but not a '3D Nand; FWIW

Can I ask what you think 3D NAND actualy is please?

Not an expert but it's supposed to be faster i/o . It's called 3D because the memory chips are stacked on top of each other in three dimensions. Previously they weren't so 2D It may be faster because the signal paths are shorter.

So you are not aware that pretty much all NAND on modern SSD's are stacked chips, and hence how you achieve the low price?

That and the increase in the number of voltage states per cell, from two with SLC, to four with MLC, eight with TLC (this drive) and sixteen with QLC.

It's worth noting that the performance of a SATA SSD is such that you'd have to try really hard to limit the performance due to the NAND, it will be more likely the controller and the lack of DRAM that will effect it.

Not much point asking if you knew the answer really

I asked if you knew what it was as you sated something as a fact, and there is always an oppotutiy every day to learn at least one thing new, which I hope you did.

What I said was that this one wasn't 3D NAND: it isn't
You asked what 3D NAND was I said it was stacked. It is
I compared it to 2D Nand which is not vertically stacked in the same way as 3D, (if it is stacked at all)
I prefixed my comments by saying I was not an expert.
If you are actually interested in giving information why not just give it rather than trying to ask trick questions, and being so patronising?

Apologies if though I was being patronising that was not the intent.

The really old 120/240GB 2017/18 versions of the A400 used planar TLC NAND, but Kingston don't operate a locked BoM policy and have since changed the NAND on the larger drives 480/960GB to 3D NAND, but that doesn't impact the performance as they are still using a budget controller and no DRAM.
