Final Words & Conclusion

Final Words & Conclusion 

The ZADAK SSD TWSG4S is a good NVMe drive. You get a high-end Phison PS5018-E18-41 controller. This is a TLC NAND product, which shows in some areas (long sustained writes). No radiator was applied originally because you can use the graphene thermal pad or the (included in the bundle) radiator. The ZADAK SSD TWSG4S should be an excellent choice for typical office users or gamers (like Zadak is aiming for); it should also be suitable for some heavy users (not literally, of course). It is the company’s best and first high-end M.2 NVMe SSD with PCI-Express 4.0 capability. The overall performance is high and always close to the available top SSD. This can be seen in synthetic tests and, more importantly, in simulating actual use. The black PCB includes Micron’s 176-layer NAND Flash TLC. It is a high-performance SSD with TLC writing, high endurance, and a 5-year guarantee. 

Do we need 5000+ MB/sec storage units?

It is a higher-end performance product, often synthetically measured, and you’d need serious workloads to get the best out of it. It is usually bought by the guys that purchase a GeForce RTX 4080/4090 or Radeon RX 6950 XT combined with some Core i9 or Ryzen 9 series processor.  Your PC isn’t going to boot faster as your OS is the bottleneck; your PC games might load a fraction of a second faster, and your application load up just as quickly as an NVMe SSD with reads/writes in the 2 GB/sec marker. In retrospect, however, we have new technologies like DirectStorage. It will allow the graphics card to load textures directly from the SSD bypassing the processor, freeing up processor cycles for other tasks, and speeding up texture load times. In this way, if they have a fast M.2 disk, they will be in the game in less than 5 seconds, even on large maps, a little time compared to the loading times we are used to today. That technology should be released for Windows 11 (and 10, but this one is not the optimal one for this technique) 

Endurance

Endurance is the number of times NAND cells can be written before they die and are mapped out; any data present on that cell is re-written to a healthy one. Bigger volume sizes mean more NAND cells; more NAND cells thus increase endurance. ZADAK SSD TWSG4S offers 100 TBW (Terabyte Written) for a 2 TB unit, which we’ve reviewed, 350 TBW for the 512 GB, and 700 TBW for the 1 TB version. So how long does a 1400 TBW storage unit last? If you are an extreme user, you might write 50 GB per day (normal users likely won’t even write that per week), but based on that value, 50GB x 365 days = 18.25 TB per year written. So that’s almost 77 years of usage. Additionally - the reviewed drive has MTBF (Mean Time Between Failures) of up to 1,600,000 Hours which is theoretically ~180 years. That’s long.

Thermals

The ZADAK SSD TWSG4S has both the graphite thermal pad and the radiator provided in a bundle (so you can choose what suits you better), which undoubtedly helps keep the temperature under control. There’s no throttling under an extreme workload. 

Performance

The ZADAK SSD TWSG4S is fast. We don’t have any negative observations about the unit. It performs as it should.

Conclusion

The ZADAK SSD TWSG4S is an M.2 2280 NVMe SSD that utilizes a Phison PS5018-E18-41 controller with a 176-layer 3D TLC NAND NAND flash to support capacities of up to 2TB. The MSRP is 265.99 USD. The SSD features a PCIe Gen 4 NVMe interface for compatibility with PCs. To keep the NVMe 1.4 standard, you do not need to install additional drivers; only ensure that your operating system is up to date. After that, install and format the SSD, and you’re good to go. ZADAK warranties the storage unit for five years / or the claimed TBW value (1,600,000 hours). Three storage capacities are available: 512 GB, 1TB, and 2 TB. We believe you will not notice the real-world effect and difference between a 3GB/sec and a 7GB/sec (and even 10 GB/s) SSD anytime soon, but DirectStorage is getting quickly supported, and that’s where it will matter. If an application loads in a fraction of a second, it will be quicker in that fraction of a second. Other than that somewhat personal remark, all lights are green, TLC, high endurance, and have a warranty (5 years). The provided graphene thermopad/radiator makes this SSD run relatively cold, and there’s no thermal throttling. For the best performance, you need a compatible Ryzen and a B550/X570/B650/X670 motherboard if you’re on the “red side.” If you like “the blue,” s – the 11^th-13th gen and Z590/Z690/Z790 boards should be chosen. ZADAK TWSG4S 2TB is a great product; the performance is top-notch, and the temperatures using the provided heatsink are too. If you want an excellent performance, you can choose that drive, which is why we’re giving it an “Approved” award.
