OCZ Vertex 4 - 512GB SSD Review & BenchMarks
OCZ is famous for its speedy SSds and capacity with reliability as well.With the launch of 512 GB Vertex 4, we can say SSDs are going to Replace HDDs very soon with more reliability, speed and life time.
support for 6Gbps SATA III on the Vertex 4, but beyond that there’s also a new model of controller: the Everest 2. It touts random average random read speeds of 95,000 IOPS and random write speeds of 85,000 IOPS (4KB, with 32-bit queue depth), both significant improvements over what OCZ offered on the same-capacity Vertex 3 (40,000 IOPS in both cases). There are gains in sequential speeds as well, though they’re less dramatic: Reads have risen from 530MBps to 535MBps and writes from 450MBps to 475MBps.
Additional features include the presence of Ndurance 2.0, a suite of NAND management features that offer reduced write amplification without compression, advanced multilevel ECC, and adaptive Redundant NAND Array technology. The Vertex 4 is also equipped with automatic encryption (with support for AES-256) and an advanced ECC engine up to 128 bits per kilobyte). OCZ also protects the drive with a five-year warranty—two more years than you got with the Vertex 3. The 512GB Vertex 4 has approximately 447GB free once it's formatted; this amounts to a price per gigabyte of about $1.47.

Vertex 4’s strong suit was in sequential writes and treatment of data compression. Its 418.6MBps result in this part of the AS SSD Benchmark is the highest we’ve seen on any drive to date, and the same was true on CrystalDiskMark (453.9MBps). (It was just barely beat out on standard 4KB writes in CrystalDiskMark by the 256GB version of the Vertex 4, which rated 99.4MBps as opposed to 95.4, and in their QD32 version by the 256GB Plextor PX-256M3, which rated 264MBps as opposed to 254.4MBps.) In SiSoftware Sandra 2012 it also attained the highest Physical Disks and sequential write scores we’ve yet seen (457MBps and 434.8MBps respectively).
OCZ plan on maintaining support for the original Everest, while Everest 2 will be released to aggressively target the demanding enthusiast user. OCZ are releasing 128GB, 256GB and 512GB Vertex 3.
And like other Indilinx-controller drives (such as the Octane), the Vertex 4 maintained consistent performance across every compression level when measured using the tool in the AS SSD Benchmark; this wasn't true of the Vertex 3.
