Product Details
The WD_BLACK SN770 is a PCIe 4×4 drive that uses the NVMe 1.4 protocol over the PCIe 4.0 bus. It comes in an M.2 2280 single-sided form factor and has a capacity of 1TB. It uses 112-layer TLC NAND flash and a homegrown WD controller that does not have a DRAM cache, but instead uses the host memory buffer (HMB) feature to access the system memory as a cache. This helps reduce the cost and power consumption of the SSD, while maintaining high performance.
The WD_BLACK SN770 has a rated sequential read speed of up to 5,150 MB/s and a rated sequential write speed of up to 4,900 MB/s. It also has a rated random read speed of up to 800,000 IOPS and a rated random write speed of up to 700,000 IOPS. It has a terabytes written (TBW) rating of 600 TBW and a mean time between failures (MTBF) rating of 1.75 million hours. It comes with a 5-year limited warranty and a free downloadable WD_BLACK Dashboard software that allows you to monitor the SSD’s health, performance, and temperature.
Features and Benefits

As you can see from the table, the WD_BLACK SN770 has a moderate price and a balanced performance among the four products. It has the highest sequential read speed and the second-highest sequential write speed, but it lacks a DRAM cache and AES encryption. The ADATA XPG Atom 50 is the cheapest and has a similar design to the WD_BLACK SN770, but it has slightly lower speeds and a higher TBW rating. The WD_BLACK SN850X is the most expensive and has the highest speeds, but it also lacks AES encryption and has the same TBW rating as the WD_BLACK SN770. The Samsung 980 PRO is the second-most expensive and has the highest random speeds and AES encryption, but it has lower sequential speeds and the same TBW rating as the WD_BLACK SN770 and the WD_BLACK SN850X.
Representative Product Reviews
To give you a better idea of what other users think of the WD_BLACK SN770, we have selected and rewritten some representative product reviews from different sources. Here are some positive and negative reviews of the SSD:
– Positive Review: “I bought this SSD to upgrade my gaming laptop and I am very impressed with the performance. It is much faster than the original SSD that came with the laptop and it runs very cool and quiet. The installation was easy and the WD_BLACK Dashboard software is very useful to monitor the SSD’s status and update the firmware. I highly recommend this SSD to anyone who wants to boost their gaming experience.”
– Positive Review: “This SSD is amazing. It delivers blazing fast speeds and high performance for gaming and content creation. It is also very affordable for a PCIe 4.0 drive and has a 5-year warranty. It works flawlessly with my AMD Ryzen system and supports the DirectStorage API for faster game loading. It is also very sleek and elegant with a black PCB and a black label. It is one of the best SSDs I have ever used.”
– Negative Review: “I was excited to get this SSD for my PlayStation 5, but I was disappointed to find out that it is not compatible with the console. The sequential read speed is below the recommended 5,500 MB/s and the PS5 does not support the HMB feature. I wish WD would make it clear that this SSD is not meant for the PS5. I had to return it and get another SSD that works with the console.”
– Negative Review: “This SSD is fast, but it has some drawbacks. It does not have a DRAM cache, which can affect the performance and endurance of the SSD. It also does not have AES encryption, which can be a security issue for some users. It also does not come with a heat sink or a heat spreader, which can cause the SSD to overheat and throttle under heavy load. I think WD should include these features in their next generation of SSDs.”
