The OCZ Vertex 3.20 SSD replaces the Agility 4 in OCZ’s mainstream consumer-class SSD line. The OCZ Vertex 3.20 derives its name from the use 20nm MLC flash compared to the previous 25nm of the original. Still utilizing a SandForce 2281 controller, the OCZ Vertex 3.20 SSD comes in 120GB and 240 GB capacities with sequential read and write speeds of 550 MB/s and 520 MB/s respectively. Compared to the previous Vertex 3 SSD which had an idle power consumption of 1.65W and active power consumption of 3W, the Vertex 3.20 uses a mere 0.55W on idle and 2.1W while in use. For users concerned about reliability, the OCZ Vertex 3.20 his endurance rated for 20GB/day of host writes for 5 years under typical client workloads and has a MTBF of 2 million hours. As with the Vertex 3 SSD, the Vertex 3.20 supports TRIM (OS dependent) and features SandForce DuraWrite architecture technology which extends flash rated endurance. The OCZ Vertex 3.20 SSD is covered by a 3-year warranty including toll-free tech support and firmware updates.
When it comes to SSD line-ups, its safe to say that OCZ has got virtually every inch of ground covered with budget, performance and all round value drives with the Octane, Vertex 3 & 4 and recently the Vector series of drives. At the same time of covering all price points, OCZ have proven reliability and a huge following of users, but now that the SSD has become more mainstream and the number of users that are adopting the faster technology grows, the market is become heavily inundated with new models meaning that for some the choice is too great and for those vendors that have been in the SSD sector for a while now, their now older models are not getting the same attention that they used to.
OCZ's Vertex line of drives in my option are some of the best selling drives out there and now that they have been around for a good couple of years and then they were one of the pioneers of using MLC NAND flash to store data on their drives, pairing it with one of the most successful controllers of the SSD world - the SandForce SF-2281. Believe it or not, this is the second re-release of the Vertex 3 and this time round OCZ have made the point of making it clear about the update to the drive.
When the Vertex 3 was first released it included 34nm MLC NAND and following the move to 25nm NAND without much of an announcement from OCZ, there was a lot of upset from the consumers with some buying the 34nm drives without a clue that 25nm were also available with some improvements to the performance. Moving forward to now, OCZ are yet again shrinking the size of technology on their drives and we now are seeing 20nm NAND - that's almost half the original Vertex 3 of two years ago. Not wanting to make the same mistake twice however, OCZ this time round are making it well known that they have updated this drive and this includes a slight tweak to the name to reflect the 20nm NAND - hence Vertex 3.20.
Late last year when I reviewed OCZ’s Agility 4 SSD, their Vertex series was still the highest performing model they offered. The Vertex offered both speed and IOPS that managed to just slightly outdo the Agility series. In what feels like a short time since that review, OCZ’s SSD lineup has re-worked considerably; putting the Vertex as their middle end drive, dropping out the Agility 4 all together, and introducing a new Vector line as the king of the hill high performer.
The key difference this time around, however, is the selection of MLC NAND. As the name indicates, the Vertex 3.20 uses 20nm MLC NAND compared to the larger 25nm / 34nm variants found on the original Vertex 3. It's part of a market-wide push for smaller flash across the board. That aside, everything else under the hood remains virtually the same although LSI now owns SandForce.
What does OCZ's 20nm flash IC die shrink bring to the table? Let's put it to the benchmarks.
The latest SSD from OCZ is the Vertex 3.20, a revised model of the winning Vertex 3, which now features 20nm NAND flash along with a proven SandForce SF-2281 controller. Considering that the Vertex 3 price has been also dropped, both SSDs fight for the same price point and deliver comparable performances.
Recently, OCZ began simplifying its SSD product line quite significantly in order to make the decision-making process easier for consumers. This was also encouraged by the fact that even budget models today offer some great performance. OCZ’s Vertex 3.20 targets that market, replacing the Agility and Vertex 3. Is it a worthy successor?
OCZ Technology have been at the forefront of Solid State designs now for many years. They released their Vertex 3 drives which featured the Sandforce 2281 controller back in 2011. This was a popular drive among the enthusiast audience as it offered excellent performance characteristics at a competitive price point. The Vertex 3.20 is a re-engineering of the original design, now incorporating 20nm Synchronous Multi Level Cell (MLC) NAND flash. OCZ’s goal is to deliver higher performance in 2013, while driving down the price.
Nachdem Hersteller OCZ Technology bereits 2011 mit den Vertex 3 Laufwerken neue Solid State Drives inkl. SATA3-Schnittstelle und SandForce SF-2281 Controller vorstellte und damit große Erfolge feierte, legt man diese Produktfamilie nun neu auf! Die namentlich als OCZ Vertex 3.20 geführte Frischzellenkur, setzt weiterhin auf den bewährten SandForce-Controller, bedient sich jedoch moderner 20 nm NAND-Flashspeicher (zuvor 25 nm), was durch den Namenszusatz ".20" entsprechend kenntlich gemacht wird. Das Ziel dieser Entwicklungen ist eine SSD für den Entry-Level-Bereich, bei der man den Fokus auf Preis/Leistung und nicht auf maximale Performance, wie bei anderen Produktfamilien im Portfolio, legt. Hierfür bietet man mit Vertex 4 und Vector nach wie vor entsprechende High-End-Drives, basierend auf neuster Controller-Technologie von Indilinx, an. Mit den 3.20er-Laufwerken trägt OCZ auch einem Trend Rechnung, auf den wir auf den folgenden Seiten näher eingehen möchten. Wir habe n uns die OCZ Vertex 3.20 mit 120 GB für einen ausführlichen Praxistest eingeladen, um die Kombination aus SF-2281 und 20 nm NAND-Speicher auf Herz und Nieren prüfen zu können. Wie immer wünschen wir Ihnen viel Spaß beim Lesen des Artikels!
