![]() ![]() Samsung is the most expensive SATA drive we were testing, but it is the only one to come with a 5-year warranty which helps justify that cost increase. Out of the field, two drives stood out to me: the ADATA SU650 240GB and the Samsung 860 EVO 250GB. Since most client workloads are likely going to be bursty and short, the post-cache write speed of these drives is not necessarily a reason to write any of them off. With that said, in bursty and shorter workloads our drives all performed much more similar to each other than in the long-term write test. When subjecting our test drives to heavy write loads, the difference between our best SATA performer in the Samsung 860 EVO and the worst in the Teamgroup MS30 was an 8.5x increase in performance. My takeaway from this testing is that even amongst SATA drives, there can still be performance differentiation. ![]() Still, it managed to stay out of the company of the Teamgroup MS30 and the Toshiba BG3, both of which turned in abysmal performance after the cache ran out. The ADATA SU650 finally shows a bit of weakness here, coming in on the bottom half of our chart. Considering the vast disparity in the short-term performance between these two drives, the post-cache write speeds between the two drives are incredibly similar. When it comes to sustained write speed, the Samsung 970 EVO NVMe drive barely manages to eke out a win compared to its SATA predecessor in the 860 EVO. While I am filling the drive with data to the 85% mark with 10 simultaneous write threads, I monitor the drive for the write performance to dip to the lowest steady point and grab a screenshot. This is not necessarily a benchmark, so much as trying to catch the post-cache write speed of the drive. The Toshiba BG3 has difficulty with this test, with a high read score but an abysmal write score despite being NVMe in nature, proving that just because a drive is NVMe does not intrinsically mean higher performance than SATA in all scenarios. The Samsung 860 EVO, our most expensive drive, turns in another good performance by leading our SATA pack in read score and turning in the second-highest write score. Here the ADATA SU650 has a standout write score thanks to very good random write performance. ![]() Here is the summarized chart: SSD Roundup Anvil 8GB ChartĪnvil gives its results in the form of a read and write score that takes into account both sequential and random traffic patterns. This benchmark was run with the 8GB test size.ĭrive-specific results can be found here: ![]() Anvil’s Storage UtilitiesĪnvil’s Storage Utilities is a comprehensive benchmark that gives us a very in-depth look at the performance of drives tested. All of the SATA drives trail the NVMe drives as expected, though they get somewhat close to catching the Toshiba BG3 in sequential write performance. That holds true with write performance as well, with the possible exception of the PNY CS900. Overall, with all of the drives turning in read performance above 500 MB/s in this short benchmark, day-to-day read performance in non-intensive workloads with these SSDs should all be similar and acceptable. The ADATA SU650 overperforms a bit, the Samsung 860 EVO is right on its heels, and the PNY CS900 underperforms on its write performance. Here is the comparison chart for your reference: SSD Roundup CrystalDiskMark 8GB ChartĬrystalDiskMark performance between most of these drives is somewhat boring to look at, at least when only comparing the sequential read and write performance numbers as we include on our chart. ![]()
