CamelCamelCamel.
Normally $300/TB
Why is it so expensive tho? I assume it is TLC and has high endurance?
Not sure, OP would you be able to provide your thoughts? You seem well accustomed to SSDs based on your previous posts.
@h0dl: This is best used for high-production workflows or something that benefits from caching, like in a NAS. From LatestInTech:
With the fast-caching Red SN700, you can handle extensive workloads in high-intensity NAS environments. Its robust system responsiveness and exceptional I/O performance are perfect for multi-users. These elements are also ideal for multitasking apps and excellent for various tasks.
These include virtualisation to collaborative-editing, to intensive database storage with efficient caching. All of these are possible while lowering your TCO.
Its fast-caching power also delivers excellent system responsiveness and I/O performance, unlike other SATA SSDs.
Handle 24/7 NAS workload environments with up to 2000TBW supported by a 5-year warranty from the company. The SN700 has the highest endurance rating among NVMe SSDs on the market.
Be in control of the challenging projects in your SMB, including virtualisation and collaborative editing, plus intensive database storage/effective caching. All these are possible while decreasing TCO.
As a PCIe 3.0 NVMe drive, the SN700 can significantly improve I/O performance. Nowadays, NAS manufacturers are releasing more units with
NVMe M.2 slots for cache drives. As a result, having SSDs that can meet the demands of a 24/7 workload environment becomes more vital.
Even during smaller operations, people working together will tax NAS systems. But with NVMe caching, it can easily handle random workloads in multitasking/multi-user applications.
Simply put, it will allow SMBs to do more.
Be ready for any data explosion with the Red SN700. The SSD in our review is the 1TB variant, but WD offers higher capacities if you need additional storage.
The SSD is built and tested for compatibility with current NAS systems. It offers maximum flexibility to enhance your workflow.

The TLDR and non-marketing speak version of this is
And that's pretty much the reason why it's more expensive than most other consumer SSD's.
Higher endurance is only one factor. Another factor is it appears to use static SLC cache. The advantage of that is there is very little, if any, recovery / foldback write penalty so you get a more consistent result. The down side is you don't get much SLC goodies.
Basically, this SSD doesn't cheat like most SSDs do nowadays. However, it does use a PCIe gen 3 x4 controller and not the latest gen NAND technology.
For NAS, a more consistent performance is preferred. While some of the flagship PCIe gen 4 x4 SSDs generally out performs it, in worst case write situation, this SSD could outperform some of those SSDs.
Would most people end up using this as their normal desktop hard drive? I don’t see the same issues here as with a NAS HDD such as loud noises. But damn it’s still $120/TB though.
