DENEVA 2 C SERIES D2CSTK251A20-0240

Since so much information is collected in each test run, we chart each drive individually, with Save Write, Journal Write, Merge Read, and Merge Write latency plotted against one another. Comparing max latency in our Web Server test, the Deneva 2 R had maximum latency measuring around In traditional synthetic benchmarks, the 24nm-based Deneva 2 comes in towards the bottom of the pack, trailing the Kingston E which offers a similar SandForce-build, but has opted to stick with more expensive 34nm-NAND. Comparing average total latency from each mainstream-enterprise SSD, the OCZ Deneva 2 performed up towards the top of the pack, although trailed the leader in this group by a wide margin. Average latency from the Deneva 2 R in our File Server preconditioning test measured strongly at 8. As we look at max latency in our 4k test, the Deneva 2 R had slightly better performance than the Kingston E with read activity measuring Veeam Announces FY Results.

Comparing latency standard deviation in our Web Server preconditioning test, the Deneva 2 R performed near the bottom of the pack as it neared steady-state. While synthetic tests will continue to be an important part of our reviews, we plan on expanding our application tests to cover a wide range of areas, including VDI performance, VM load generation, expanded database performance tests, and many other areas. The Kingston E performed very similarly to the OCZ Deneva 2, although each latency group measured slightly higher over the course of the test. Average latency in our Web Server preconditioning test leveled off around ms as the drive neared steady-state, staying higher than the Intel and Micron drives, but competitive with the Kingston. Our Enterprise Synthetic Workload Analysis includes four profiles based on real-world tasks. In traditional synthetic benchmarks, the 24nm-based Deneva 2 comes in towards the bottom of the pack, trailing the Kingston E which offers a similar SandForce-build, but has opted to stick with more expensive 34nm-NAND.

The remaining feature on the drive is its standard SATA power and data connectors on the front. Comparing latency standard deviation in our Web Server preconditioning test, the Deneva 2 R performed near the bottom of the pack as it neared steady-state.

The initial peak speeds were class-leading, though after the first couple of hours the Deneva 2 R lost its edge. Our Enterprise Synthetic Workload Analysis includes four seeries based on real-world tasks. As 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.

With the overall average latency chart showing how well each drive performed over the course of the hours of testing, its also helpful to see how well the drive performed over the entire testing period.

OCZ Deneva 2 C (GB, “, MLC Async) Overview – CNET

These numbers are quite impressive given the class. In these tests, we span workload intensity from 2 threads and 2 queue up to 16 threads and 16 queue. The Kingston E performed very similarly to the OCZ Deneva 2, although each latency group measured slightly higher over the course of the test.

Measuring the internal latencys seen by the MarkLogic software, we record both total average latency, as well as interval latency for each SSD. While traditional benchmarks might paint a bleak outlook, in our new application-level testing, the Deneva 2 ranked fairly well. The Deneva 2 competes in a tough market with heavyweights that include the new Intel DC S as well as the Micron Pm that compete in the same price category.

One more design note is that architecturally, the Deneva 2 comes in a 2. Home Lab Horror Stories. We also included two legacy mixed workloads, the traditional File Server and Webserver, each offering a wide mix of transfer sizes. Average latency in our Web Server preconditioning test leveled off around ms as the drive neared steady-state, staying higher than the Intel and Micron drives, but competitive with the Kingston.

As for performance figures on the Deneva 2 R, OCZ claims that it doubles speed compared to the previous generation. Flash performance varies throughout the preconditioning phase of each storage device. Veeam Announces FY Results.

The Intel model came in at the top, with the Deneva 2 staying at the bottom. As with other SSDs, the side profile presents the screw holes that enable the drive to be mounted.

The Deneva d2cstk251aa20-0240 R measured between ms in steady-state.

Deneva 2 GB Internal Solid State Drive – Retail Pack – video dailymotion

The Intel S ranked at the top of the pack with the peak measured latency measuring around 25ms, made up in bulk by the Journal Writes. While most enterprise SSD vendors show an array of products ranging from read-intensive entry-enterprise environments to high-performance mixed workload SAS use cases, OCZ’s plan is more fluid. Write latency was more comparable to the Kingston at They offer up essentially any NAND variety mixed in with optional power-fail protection and over provisioning R series.

Since so much information is collected in each test run, we chart each drive individually, with Save Write, Journal Write, Merge Read, and Merge Write latency plotted against one another. When we compared max latency between the GB SSDs, the Deneva 2 R had max response times ranging between ms in steady-state, which placed it in the middle of the pack.

In this section, the Deneva 2 R offered the highest burst speeds, yet as it arrived at steady-state, it was at the bottom of the four SSDs with the Kingston. Veeam Introduces Instance Licensing. We measured peaks as high as ms, with many peaks measuring between ms. 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.

Switching focus to latency consistency in our File Server preconditioning test, the Deneva 2 R tested well with the Kingston, and then it slipped toward the bottom middle of the pack as it neared steady-state.

As we look at max latency in our 4k test, the Deneva 2 R had slightly better performance than the Kingston E with read activity measuring While this kind of model could be construed as a complicated offering since there are so many configurations, the reality is that OCZ is attempting to offer products that can be customized for specific application requirements.

The drive comes in a 2. However, OCZ has an answer there as well; their standard issue C series Deneva 2 can be purchased in single units at retail. In the enterprise market there is a huge difference between how products perform on paper and how they perform in a production environment. Apricorn Aegis Secure Key 3z Review. The next workload is our File Server profile, which covers a wide range of transfer sizes spanning from b to K.

The Deneva 2 also comes in two different series to provides users flexibility in their choices. Comparing average total latency from each mainstream-enterprise SSD, the OCZ Deneva 2 performed up towards the top of the pack, although trailed the leader in this group by a wide margin.

In lowest overall average latency, it tested well at second place d2cstk251aa20-0240 the Intel S, but ahead of the Kingston E and Micron Pm. DigitalOcean Launches Managed Databases.

OCZ Deneva 2 C (240GB, 2.5″, MLC Async)

Cisco Announces 2Q19 Earnings. Nearing steady-state in our File Server preconditioning test, the Deneva 2 R had max latency ranging from 60 to 80ms in burst, and then it jumped up to the range nearing steady-state.

The over-provisioning is geared more toward heavier write scenarios and is noticeable when users check capacity differences between the C and R models.
