The 128GB Vertex 450 has a reasonable but somewhat unusual performance profile. The main weakness is its sequential write speed which is only 282 MB/s peak. This implies that the 128GB version has fewer NAND modules than both its larger 256GB sibling and several other leading 128GB models. Other SSDs, including some 128GB models can consistently achieve sequential write speeds in the 500 MB/s range. A handicap of this magnitude on a key performance metric would normally relegate an SSD to the lower divisions but the Vertex 450 offsets its poor sequential write speed with a record breaking 4K write speed of 158 MB/s which is the highest I have ever seen on any SSD. Overall the Vertex 450 has an average, but quirky, performance profile and is reasonably priced however there are both faster and cheaper alternatives available on the SSD leaderboard.  [Feb '14 SSDrivePro]

The Intel 535 SSD was quietly released in April 2015, very few review samples were distributed and the release went largely unnoticed. The 535 sports the same basic specs as its predecessor, the 530. The 20nm NAND in the 530 has been replaced with marginally slower 16nm NAND and both drives use the same five year old SandForce 2281 controller. Comparing performance between 240GB 530 and 535 shows that the two drives share the same performance profile which is severely hampered by a particularly weak incompressible write speed, something the SandForce controller is notorious for. Overall the 240GB 535 scores an effective speed of 71.5% which puts it amongst the slowest handful of new SSDs on the market. There are other drives on the market that use newer technology and represent far value for money. [Aug '15 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
