OCZ Vertex 4 SSD Revisited: 128GB and New Firmware
6 September 2012
Conclusion: To put it succinctly, the 128GB Vertex 4 delivered somewhat of a mixed bag of performance results. In some tests it bested the field, while in others it couldn't keep pace. Like the previous Vertex 4s, the 128GB version didn’t do very well in SANDRA, a couple of the HD Tune tests, or the ATTO write test, but it shined like a jewel in most of the CrystalDiskMark tests and the Default IOMeter test, while it held its own in PCMark 7.
Pros: Excellent price and value, 5-year warranty, Much better sequential reads with firmware update
Cons: Weak write performance in some tests, Larger-capacity V4s offer same value, better performance
Summary: Flagship solid state drives from OCZ – Vertex 4 – underwent yet another spec modification caused by the release of the new firmware version 1.5. Therefore, we decided to retest the “updated” Vertex 4 SSDs and try to figure out the reasons behind the notorious performance drop after filling up more than half of the available space.
OCZ Vertex 4 256 GB and 512 GB Solid State Drives Review
29 May 2012
Summary: About a month ago OCZ launched a completely new family of high-performance SSDs based around the proprietary Indilinx Everest 2 controller, and very recently they released new firmware version 1.4 for it, which was supposed to increase its speed even more. Will this make Vertex 4 the fastest consumer grade SSD with SATA 6 Gbps interface? Let’s find out!
Conclusion: The Indilinx Everest 2 controller is a real competitor to SandForce and Marvell, but for the everyday user, we see no compelling reasons to overlook the tried and trusted for something new and unproven.
Summary: In questi giorni ci è giunta notizia, inizialmente ufficiosa, poi confermata direttamente da OCZ, che i controller Everest ed Everest 2 utilizzati sulle linee di prodotti Octane, Petrol e Vertex 4 non sono effettivamente prodotti da OCZ come tutti pensavamo; si tratta, infatti, di controller prodotti da Marvell rimarchiati da OCZ e dotati di firmware sviluppato da Indilinx.
