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

70 Mbps (Image credit: TeraBox)Test 1 - Sync speedFor our first test, we copied a 650 MB folder to the application directory, measuring how quickly the desktop client was able to sync the files to the cloud. The folder contained 22 files including MP3s, images, metadata files and a PDF. We didn't have much joy syncing data with the TeraBox cloud in our original tests in 2022. It took us several attempts to upload our 1GB test file, with progress coming to a halt on all but our ninth attempt. This final, successful upload was complete in under four minutes, which is very respectable when compared with other cloud drives, although we do have concerns over the service’s stability.We would typically expect a download to complete significantly quicker than an upload with our typical Internet connections, however this is where TeraBox’s speed throttling comes into play. Using our free account, the same 1GB was re-downloaded in under nine minutes. This would have been reasonable before the introduction of high-speed Internet connections; most other competitors manage the same download in less than half the time, with several sub-one-minute times.Our most recent tests in 2023 performed much better. Our data uploaded in just under 105 seconds. Our upload speed averaged 70Mbps but as before we were victims of TeraBox's throttling which slowed the upload below cloud storage competitors like Dropbox and OneDrive.(Image credit: TeraBox)Test 2 - File recoveryIn this test, we deleted the folder from the application directory, removing it from the device. After seeing whether the files were gone from the cloud drive, we looked to see if it was possible to recover them. As TeraBox only offers a cloud drive rather than local sync of files we decided to delete our test folder from the Files section of the client itself. As soon as we did a helpful pop up appeared informing us that deleted files would be stored for 10 days in the Recycle Bin but this could be extended to 30 days with a Premium subscription.Once we confirmed deletion, another pop up appeared pointing to the Recycle Bin
