OCZ RevoDrive Conclusion
IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete. Please do not base any purchase solely on our conclusion, as it represents our product rating specifically for the product tested which may differ from future versions. Benchmark Reviews begins our conclusion with a short summary for each of the areas that we rate.
Our performance rating considers how effective the 240GB OCZ RevoDrive X2 performs in operations against direct competing SSD storage solutions, especially the original RevoDrive. In our benchmark tests, the RevoDrive X2 delivered 831/688 MBps peak read and write speeds using ATTO Disk Benchmark. 831 MB/s measured in ATTO clearly exceeds the manufacturer's 740 MB/s specified maximum read speed, making this the fastest storage solution Benchmark Reviews has ever tested. Operational performance measured 112061 IOPS when tested with a queue depth of 32 using Iometer. Developers needing top-end operational speeds and functionality for their demanding applications can certainly expect as much from the OCZ RevoDrive X2 PCI-Express SSD. Linear speed tests with the AIDA64 Disk Benchmark produced a solid 756 MBps read speed, which is above spec, yet dirty NAND combined with lacking TRIM support still offered 629 MBps peak write speed when the drive was filled.
Benchmark Reviews also tested the OCZ RevoDrive X2 SSD against many of its closest competitors, including a SandForce RAID-0 SSD set, and the performance results were still very impressive. In fact, the OCZ RevoDrive X2 offered incredibly fast speeds compared to the other SSDs, including the SATA-based RAID-0 set of separate SandForce SF1200's. Operational performance tests place the RevoDrive X2 at the very top of our charts, well ahead of other single and RAID-0 SSDs. High-performance computer enthusiasts will enjoy the immediate response time that assures instant reactions when called upon. Based around the SandForce SF-1222TA3-SBH processor, DuraClass technology adds proprietary RAISE and DuraWrite features not available to other SSDs. The end result is a product that could last up to five times longer with less wear on NAND flash modules due to 7% over-provisioning.
SSDs are not prone to mechanical failure, but if any RevoDrive products happen to fail during the 3-year warranty period end-users may contact OCZ via the company website or extensive support forums. Fortunately, there's also a toll-free telephone number (800-459-1816) for free technical support and customer service questions. OCZ has been proven to be one of the best companies in the business when it comes to customer service, and replacement parts are often sent with priority delivery.
The OCZ RevoDrive X2 PCI-E SSD series offers a prolonged MLC NAND flash lifetime and delivers data redundancy thanks to the powerful SandForce SF-1222 solid state processor that has innovated the SSD industry. PCI-Express form factor or otherwise, SandForce SSDs have taken the storage market by storm. This helped products like OCZ's Vertex 2 SSD to dominate the high-performance PC hardware segment, and will likely lend support to the OCZ RevoDrive series for ultra-performance enthusiasts. SandForce-driven Solid State Drives are already extremely fast and offer SLC-level NAND durability at MLC cost, but combining two SF-1200 controllers onto a single-platform in RAID-0 delivers unprecedented operational I/O performance.
As of 19 November 2010, OCZ's 240GB RevoDrive X2 PCI-Express SSD series sells for $648.40 at Amazon / $679 at NewEgg with various capacities available. Considering that users get roughly twice the performance, there definitely a competitive argument to be made with regard to value. List below is the current OCZ product line of SandForce-driven SSDs:
OCZ isn't vying for the value play with their RevoDrive X2 series, and they don't need to. The OCZ Agility 2 and OCZ Vertex 2 SSDs offer outstanding value for their respective performance levels. What you get with RevoDrive is performance, raw full-throttle performance. The RevoDrive X2 SSD is a great fit for systems that require extreme-performance, or enthusiasts wanting the fastest speeds and best operational performance money can buy. While I'm hesitant to recommend any RAID-0 storage solution for business environments (even with routine backups), the SandForce-specific RAISE and DuraWrite features alleviate these concerns and make allow the RevoDrive series to fit-in well with any: virtual machine server, remote-access application server, high-transaction database server, and extreme-traffic web servers.
In conclusion, OCZ's RevoDrive X2 PCI-Express SSD offers two things not available in any other consumer SSD: bandwidth speeds well beyond SATA-6.0 GB/s capabilities, and absolutely incredible operational IOPS performance. As expected, these perks come at the expense of several coveted storage utilities: TRIM garbage collection, Native Command Queuing (NCQ), and Self-Monitoring Analysis and Reporting Technology (SMART) functionality. Until Silicon Image is able to incorporate these features into their driver so they'll pass through to the SSD, users will depend on SandForces' otherwise noteworthy NAND management to keep up these lightning-fast transfer speeds.
+ Delivers approximately 120,000 4K IOPS in Iometer
- SiI3124 RAID controller lacks NCQ, SMART, and TRIM pass-through
Final Score: 8.75 out of 10.
