OCZ Vertex 4 (512GB)
Our initial glance of how OCZ would proceed a high-capacity solid-state expostulate (SSD) marketplace following a acquisition of controller developer Indilinx in Mar 2011 came with a 512GB Octane late final year. But that expostulate was a new model, so how would a pierce from SandForce hardware impact OCZ’s existent SSD lines? We’re saying that now with a recover of a Vertex 4 series, that introduces Indilinx controllers into OCZ’s renouned and high-performing consumer line. Judging by both a 256GB version and this 512GB chronicle (which is labelled during $699 list), a formula are a tentative—but not total—success.
Of march you’ll find support for 6Gbps SATA III on a Vertex 4, nonetheless over that there’s also a new indication of controller: a Everest 2. It touts pointless normal pointless review speeds of 95,000 IOPS and pointless write speeds of 85,000 IOPS (4KB, with 32-bit reserve depth), both poignant improvements over what OCZ offering on a same-capacity Vertex 3 (40,000 IOPS in both cases). There are gains in consecutive speeds as well, nonetheless they’re reduction dramatic: Reads have risen from 530MBps to 535MBps and writes from 450MBps to 475MBps.
Additional facilities embody a participation of Ndurance 2.0, a apartment of NAND government facilities that offer reduced write loudness yet compression, modernized multilevel ECC, and adaptive Redundant NAND Array technology. The Vertex 4 is also versed with involuntary encryption (with support for AES-256) and an modernized ECC engine adult to 128 pieces per kilobyte). OCZ also protects a expostulate with a five-year warranty—two some-more years than we got with a Vertex 3. The 512GB Vertex 4 has approximately 447GB giveaway once it’s formatted; this amounts to a cost per gigabyte of about $1.47.
You can design all these changes to interpret to some opening boost, nonetheless not as most as we competence design or we competence see from a Octane. Compared with a 480GB Vertex 3, a Vertex 4’s pointless speeds were considerable as totalled on a AS SSD Benchmark: 7,515 IOPS contra 6,155 with 4KB reads and 21,592 contra 5,057 on 4KB writes. With a series of threads upped to 64, a Vertex 4’s 70,546 IOPS leapt over a Vertex 3’s 55,868 on reads, and a 65,815 on writes towered over a Vertex 3’s 38,096. The drives 512-byte review formula were allied (16,370 IOPS for a Vertex 3, 16,697 for a Vertex 4), nonetheless a newer drive’s 26,555 on writes catapulted past a Vertex 3’s 4,554. Its outcome in SiSoftware Sandra 2012’s Random Write exam (419.7MBps) is also well above a nearest aspirant (the 256GB Vertex 4, with 346.3MBps).
Otherwise, a Vertex 4’s clever fit was in consecutive writes and diagnosis of information compression. Its 418.6MBps outcome in this partial of a AS SSD Benchmark is a top we’ve seen on any expostulate to date, and a same was loyal on CrystalDiskMark (453.9MBps). (It was only hardly kick out on customary 4KB writes in CrystalDiskMark by a 256GB chronicle of a Vertex 4, that rated 99.4MBps as opposite to 95.4, and in their QD32 chronicle by a 256GB Plextor PX-256M3, that rated 264MBps as opposite to 254.4MBps.) In SiSoftware Sandra 2012 it also achieved a top Physical Disks and consecutive write scores we’ve nonetheless seen (457MBps and 434.8MBps respectively). And like other Indilinx-controller drives (such as a Octane), a Vertex 4 confirmed unchanging opening opposite each application turn when totalled regulating a apparatus in a AS SSD Benchmark; this wasn’t loyal of a Vertex 3.
But if we direct aloft review speeds, this Vertex 4 competence not be a best for you. The Octane and a 480GB Vertex 3 were distant improved during consecutive reads in a AS SSD Benchmark (503.3MBps and 491.9MBps respectively, opposite 429.3MBps) and on CrystalDiskMark (481Mbps and 499MBps contra 465.3MBps), and achieved a aloft Physical Disks review measure (523.3MBps and 512MBps contra 429.7MBps) in Sandra; went toe to toe (and infrequently further) via a ATTO Disk Benchmark; and a Vertex 3 even did improved than possibly expostulate in a Futuremark PCMark 7 delegate storage exam (5,430 contra 5,147 for the 512GB model and 5,225 for a 256GB one).
There’s no doubt that a 512GB OCZ Vertex 4 is a good expostulate overall, nonetheless it’s not going to be a fantastic one for each user. For bland computing, a optimizations for pointless opening will be helpful; and for consecutive essay of files, quite during aloft reserve depths, it’s tough to kick right now. But consecutive reads are a opposite story, and if we know we count on those regularly, a Vertex 3 is expected a improved choice during a moment, even nonetheless it lists for somewhat some-more ($769). The Vertex 4 shows that OCZ’s matrimony to Indilinx is not yet a benefits, even if not everybody is guaranteed to see them.
