The eMLC 24nm NAND helps to increase the endurance and long-term viability of the SSD, while giving a substantial cost benefit over SLC-based SSDs.Īs seen in our Deneva 2 R sample, this version includes power-fail capacitors to allow data in flight to be written to NAND in the event power on the host system is lost. This gives the SSD a total capacity of 256GB, with 200GB usable which has been over-provisioned for users. The 200GB OCZ Deneva 2 R model utilizes a SandForce SF-2582 controller and 16 NAND die in 16GB NAND packages. The remaining feature on the drive is its standard SATA power and data connectors on the front. The drive comes in a 2.5" form factor, and the spec sheet dimensions place it near 9.5mm for standard applications. On the bottom of the drive is the Deneva 2 R’s barcode sticker with drive information.Īs with other SSDs, the side profile presents the screw holes that enable the drive to be mounted. The top-side sticker labels the drive with OCZ Deneva 2 branding on a blue backdrop and also provides white space for the drive to be user-labeled.
The OCZ Deneva 2 R has a much different appearance than the OCZ Talos 2 SAS model we reviewed, with a full label covering the top and a metallic gray casing for the body.
The R series includes a similar feature set to the C series but with a couple of additional features including power loss data protection and over-provisioning. The over-provisioning is geared more toward heavier write scenarios and is noticeable when users check capacity differences between the C and R models. The Deneva 2 also comes in two different series to provides users flexibility in their choices. Our test model incorporates eMLC NAND to offer users more write cycles than standard MLC, and simultaneously it provides economics closer to MLC than the more expensive SLC. But having the SSD utility installed is a great way to monitor the OCZ RD400 (specially it’s health and temperature) or keep it up to date.The OCZ Deneva 2 is an enterprise-class SSD that interfaces over SATA 6GB/s and has several different models utilizing an array of NAND.
It is not required that you install this utility before you can use the RD400. You may or may not need to install the SSD Utility. The SSD Utility also alerts you if the drive is not functioning properly or its temperature is getting too high. This option is for advanced users, but for most users we should be fine with its default state. You can also set or change the over provisioning of the SSD. If you are in doubt whether your SSD is functioning well or not, you can use the tuner to see how your SSD performs.
It helps you to monitor the drive’s health, temperature, update the drive’s firmware and other information. The OCZ SSD Utility offers a number of information regarding your storage drive. The package doesn’t include any CD installer, and you will have to download this utility from OCZ’s site. Toshiba is offering a free SSD utility so that you can monitor your OCZ SSD and keep it up to date.
