The Vertex 450 is the third SSD OCZ have released in the last eighteen months. The 450 features an updated version of the now somewhat proven Indilinx Barefoot controller which was first seen in the Vector just over 9 Months ago. The core performance figures for the Vertex 450 are disappointingly weaker, albeit marginally, than both the Vector (by 16%) and the Vertex 4 (by 11%). The Vertex 450 is currently retailing for more than the Vertex 4 and roughly the same as the better performing Vector so the 450 cannot be recommended at this time. That said the 450 is still amongst the top ten SSDs currently on the market and will be well worth consideration when prices drop after retailers have had a chance to build up stock. [Sep '13 SSDrivePro]

MORE DETAILS

The OCZ Vertex 460 replaces the Vertex 450. The main difference between the two is a change from Intel/Micron (IMFT) 20nm MLC NAND to Toshiba 19nm MLC NAND, a fitting move considering that Toshiba acquired OCZ shortly before the Vertex 460's release. Comparing the Vertex 460 and 450 shows that the two drives are broadly on a par in terms of performance. In terms of pricing the Vertex 460 is priced reasonably considering its age, I expect prices will drop rapidly as retailers build stocks of the relatively new drive. At current prices the 240GB Vertex 460 represents above average value for money but struggles to compete with its slightly more expensive sibling, the Vector 150. Comparing the 460 and 150 shows that Vector 150 leads in terms of effective speed by 10% but only costs 5% more than the 460. [Mar '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.
