Additionally, the durability on the WD Black SN770 SSD is largely the same as the SN850, despite its lower performance, so you won’t be seeking out any additional workload out of the more efficient drive. Let’s get the SN770 SSD into the test machine and see how it performs.WD Black SN770 SSD Review – Testing & BenchmarksNow we know how the WD Black SN770 SSD is built, it’s time to put it through its paces. I used a midrange test machine and several different pieces of test benchmarking software (CrystalDisk, ATTO, AS SSD, AJA) to measure how this DRAMless SSD performed.Test Machine:Windows 10 Pro Desktop SystemIntel i5 11400 Rocket Lake – 6-Core 2.6/4.4Ghz16GB DDR4 2666MHz MemoryIntel B560M mATX MotherboardOS Storage, Seagate Firecuda 120 SSDTest SSD connected to Secondary PCIe Gen 4×4 M.2 SlotYou can hear more on how the test was conducted and those results in full in the video below:Using CrystalDisk, we got a good measure of the drive and verified that this PCIe Gen 3 x4 SSD was indeed using the 4×4 lane. Additionally, the temp averaged out around 45 degrees between each test being conducted.Another important area to note whilst the WD Black SN770 SSD was being tested was that the temperature of the controller increased notably during each sustained test. I used a standard $10 m.2 heatsink and even with a 1-minute cool-down between each test, the SSD reached the 60 degrees mark very quickly.The first range of tests were using ATTO Disk benchmark and three separate file sizes were used, 256MB, 1GB and

From its SMART sensors. CrystalDiskMark can also benchmark SSD drives. However, be aware that using CDM frequently may expedite your drive's failure as it writes a great deal of information to hard drives. The astute may notice that my drives are actually substantially underperforming. SSDLife: SSDLife does about a quarter of the work CrystalDisk does, however, it has the advantage of specialization, telling you exactly how much data has been written to your drive. AS SSD: AS SSD reigns as the king of benchmarks for solid state drives. If you elect to bench your drives, give AS SSD a try. As you might notice from the screenshot below, my write performance is abysmal for an SSD. Especially for a RAID array. Snake-oil SSD Optimizers Configuring your system for fewer writes will extend its lifespan. Fortunately, modern operating systems already optimize SSDs out-the-box. Windows 7 and 8 do virtually everything for you. On the other hand, Windows XP does not – and so a toolkit may provide some degree of benefit for XP. Unfortunately, many SSD optimizers will do quite a bit of damage to your drive. Avoid any “optimizer” claiming to defragment or erase empty space. Defragging an SSD will only cause a tremendous number of writes and won’t increase your drive’s speed. Conclusion I recommend the following: If you’re having issues with your SSD, consider benchmarking or using an analysis tool to determine the kind of issue. Slow writes generally imply a fault within either TRIM, firmware or garbage collection. If it does display such a fault, use an optimization toolkit to streamline the drive. If you use a notebook and are looking for additional optimization tips, check out Simon's roundup of the best five tips for improving notebook performance. Matt, on the other hand, recommends moving write-intensive operations to a standard platter-based drive. Does anyone else have any optimization toolkits, software or tips for SSDs?

4GB. Each test was conducted upto 64MB I/O and we recorded the sequential performance and the IO/s:ATTO Disk Benchmark Test #1256MB File PEAK Read Throughput = 4.91GB/s256MB File PEAK Write Throughput = 4.62GB/sATTO Disk Benchmark Test #21GB File PEAK Read Throughput = 4.88GB/s1GB File PEAK Write Throughput = 4.62GB/sATTO Disk Benchmark Test #34GB File PEAK Read Throughput = 4.88GB/s4GB File PEAK Write Throughput = 4.49GB/sThe next test of the WD Black SN770 SSD involved CrystalDisk Benchmark and I tested a 1GB, 4GB and 16GB File scale.CRYSTALDISK MARK 1GB TESTCRYSTALDISK MARK 4GB TESTCRYSTALDISK MARK 16GB TESTNext, I switched to AS SSD benchmark. A much more thorough test through, I used 1GB, 3GB and 5GB test files. Each test includes throughput benchmarks and IOPS that are respective to the larger file sizes (important, if you are reading this and trying to compare against the reported 4K IOPS from the manufacturer).AS SSD Benchmark Test #1AS SSD Benchmark Test #2AS SSD Benchmark Test #3Ordinarily, I would introduce tests like BlackMagic and AJA into the mix here, but even a short burst of testing on an NVMe like this would over saturate the cache memory on board. Nevertheless, in the short term we still could ascertain the reported performance on 1GB, 4GB and 16GB file testing was:4GB AJA File Test Results (Peak) = 4,357MB/s Read & 4,711MB/s Write16GB AJA File Test Results (Peak) = 4,364MB/s Read & 4,715MB/s Write16GB AJA File Test Results (Peak) = 4,715MB/s Read & 4,371MB/s WriteThe overall performance throughout all testing largely exceeded the reported maximum by WD themselves, which I was very impressed by. Sustained performance was unsurprisingly poorer as the borrowed system memory and controller became overworking in the larger and longer-running tests, but in shorter bursts, the drive clearly did what they said it can do and more. Let’s conclude today’s review and work out what we think of the WD Black SN770 SSD.WD Black SN770 SSD Review – Conclusion & VerdictYou can not really fault the WD Black SN850 SSD in terms of what Western Digital has said this drive can do, as it not only meets those expectations consistently but also exceeds it more often than not by a few degrees. The WD Black SN850 SSD is not going to challenge the current generation of 7K performing drives, but then it is not trying to. This is a mid-range SSD that serves as an entry point into PCIe 4 storage for many and in that tier of storage, the WD Black SN770 SSD unquestionably succeeds. That said, this SSD is at this price and at this power efficiency by design and the fact it took WD this long to release a 2nd entry into their PCIe4
