The WD Black SN850X has a superb consumer performance profile. As well as offering solid burst speeds of 5 GB/s, the SN850X also offers respectable out of cache performance. At current prices (1TB $90 USD, 2TB $145 USD and 4TB $290 USD) the WD Black SN850X is our top value pick at every capacity. [Jun '24 SSDrivePro]

MORE DETAILS

The Intel 320 SSD uses a proprietary Intel controller which predates Intel's adoption of Sandforce controllers for their consumer SSDs. The 320 is nearly three years old and consequently has a particularly poor performance profile. With peak and average sequential read/write speeds of 260/135 and 208/107 MB/s the 120GB Intel 320 is about half as fast as the current group leaders. Peak small file 4K read/write speeds clock in at 19/37 MB/s, again around half as fast as the current group leaders. Overall the 120GB Intel 320 has an effective speed of 214 MB/s. Although these speeds are only around half as fast as current SSDs, they are still twice as fast sequentially and 15x faster than the fastest mechanical drives. [Feb '14 SSDrivePro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
