Toshiba PX02SS Enterprise SSD Review

The Toshiba PX02SS is a 2.5-inch enterprise SSD designed for transaction-intensive workloads including OLTP database applications and features a dual-port 12Gb/s SAS3 interface. The PX02SS and is available in 100GB, 200GB, 400GB, and 800GB capacities and offers notable write endurance among its class due to an overprovisioned Toshiba 24nm eMLC architecture. The Toshiba PX02SS is specified for 5.48PB total bytes written for the 100GB edition up to 43.8PB TBW for the 800GB SSD.

Toshiba PX02SM Series SAS3 Enterprise SSD Review

The Toshiba PX02SM is an enterprise SSD which utilizes a dual port 12Gb/s SAS interface and eMLC NAND and achieved promising results in our early review of the drive. The PX02SM was the first 12Gb/s SAS SSD on the market, predating access to SAS3 adapters that could allow the StorageReview Enterprise Test Lab to measure its maximum performance with sequential workloads. With the addition of a Supermicro SuperStorage Server AR24NV SAS3 platform to the lab, we can revisit the PX02SM and put it through its paces without HBA bottlenecks from the host or custom configurations.

HGST Ultrastar SSD800MM SAS3 Enterprise SSD Review

When we originally reviewed the HGST Ultrastar SSD800MM, at the time we were limited to showing SAS 6Gb/s performance in our primary enterprise testing platforms. Though we did run a synthetic data performance data at 12Gb/s using a custom cable harness, it didn't follow our standard protocol of testing on enterprise-ready platforms and hardware. The results represented more of a technology preview than an actual performance review. Now with the Supermicro SuperStorage Server AR24NV SAS3 certified platform, we’ll be able to capture real world results of this and future SAS3 drives.

OCZ ZD-XL SQL Accelerator Review

The OCZ ZD-XL SQL Accelerator is a duty-specific combination of hardware and software designed explicitly, as the name implies, to accelerate SQL databases. ZD-XL leverages an OCZ Z-Drive R4 RM series PCIe application accelerator as the flash storage layer combined with a host application to either accelerate a SQL volume on hard drives or accelerate a SQL database by placing it in flash. Its biggest differentiator though is a third option; if the situation calls for it ZD-XL can do both - accelerate a SQL volume on the flash card and cache large databases that reside on HDDs.

SanDisk Optimus Eco 400GB SAS SSD Review

The Optimus Eco uses SanDisk’s Guardian Technology Platform to improve the performance characteristics for 19nm multi-level cell (MLC) flash in order to suit read-intensive application workloads in capacities of 400GB, 800GB, 1.6TB, and 2TB. The Guardian Technology Platform was part of SanDisk’s recent acquisition of SMART Storage Systems, which also put the platform to good use last year in our review of the Optimus SAS Enterprise SSD. The Optimus Eco represents a different use profile and different NAND than the Optimus but still achieves solid results across our benchmarks, flexibility that helps explain the appeal that SMART’s MLC technology and engineering resources have for SanDisk.

Micron P420m Enterprise PCIe SSD Review

The Micron P420m is an enterprise application accelerator that ranges up to 1.4TB in total capacity that leverages the PCIe interface and is uniquely offered in both a half-height, half-length (HHHL) and 2.5" form factors. Micron has opted for 25nm MLC NAND for the P420m to meet not only mainstream market requirements for performance and reliability, but also to provide a more cost-effective and higher capacity offering than their P320h which is paired with SLC NAND. The other core difference between the P420m and the P320h is that Micron has added capacitors to protect in-flight data in the event of an unplanned loss of power. The additional data protection feature keeps the card powered long enough to flush all writes to the NAND, giving enterprises one more layer of data protection. The HHHL card interfaces via PCIe Gen2 x8 to achieve sequential read performance up to 3.3GB/s with writes up to 630MB/s and random reads up to 750,000 IOPS and 95,000 IOPS for write activity. The 2.5" interfaces over PCIe Gen2 x4 for up to 1.8GB/s and 430,000 IOPS, respectively.

SMART Storage CloudSpeed 1000E Enterprise SSD Review

The SMART Storage Systems (a SanDisk company) CloudSpeed 1000 is a 7mm 2.5" enterprise SSD engineered for server and cloud computing environments. The drive offers a 6Gb/s SATA interface, capacities from 100GB to 960GB, and utilizes 19nm MLC NAND with specialized features designed to offer high endurance. The CloudSpeed 1000 from Smart comes in two variations, the 1000 and 1000E, to meet the varying needs of organizations that require either maximum capacity or greater levels of endurance. The CloudSpeed 1000 ships in capacities of 120GB, 240GB, 480GB and 960GB, while the CloudSpeed 1000E arrives in 100GB, 200GB, 400GB and 800GB models. That extra over-provisioning on the 1000E model yields 7,680TBW, with the 1000 at 3,070TBW.

Huawei Tecal ES3000 Application Accelerator Review

The Huawei Tecal ES3000 is a family of full-height half-length enterprise application accelerators that leverage MLC NAND in capacities up to 2.4TB and PCIe interface (2.0 x8). On the surface the Huawei cards sound similar to many other products on the market, but a deeper look reveals a unique triple controller design that joins two PCBs together to form an impressive offering. On the top end of the performance scale this means 3.2GB/s max read bandwidth and 2.8GB/s write. From a latency angle, all thee capacities can drive 49µs and write latency of 8µs. The cards have a number of additional features as well including enhanced error checking, power fail protection and mechanisms to drive enhanced endurance over the course of their life.

Fusion-io ioDrive2 MLC Application Accelerator Review (1.2TB)

The Fusion-io ioDrive2 MLC application accelerator comes in capacities up to 1.2TB in a half-height half-length (HHHL) form factor (or 3TB in FHHL) and is highlighted by exceedingly low read and write access latencies. While we've previously reviewed the ioDrive2 flagship Duo SLC, which is great for the most demanding applications, the ioDrive2 single drive with MLC is designed for more "pedestrian" workloads. Pedestrian in ioMemory language though means applications like databases that can accept read latencies of 68µs, compared to the 47µs latency found in the higher-end SLC ioDrive2. Of course offering the drive with MLC NAND brings with it benefits like reduced cost, and the MLC iteration also comes in higher capacities. The ioDrive2 single MLC comes in at a maximum 1.2TB capacity in HHHL or 3TB in FHHL, while the SLC Duo tops out at 600GB and 1.2TB respectively (though the Duo featured with MLC maxes at 1.2TB HHHL and 2.4TB FHHL capacities).

HGST Ultrastar SSD800MM Enterprise SSD Review

The HGST Ultrastar SSD800MM enterprise SSD is the second 12Gb/s SAS interface SSD available on the market and features co-developed Intel/HGST controllers and 25nm MLC NAND. The SSD800MM, which as the name indicates offers up to 800GB of capacity, fits into a new family of drives presented by HGST. The other SSDs in the series are the SSD800MH and SSD1000MR, and the whole line has been designed with the most demanding applications in mind such as big data analytics, high-frequency trading, online banking and cloud computing. On top of that, the SSD800MM is designed to be energy efficient with an option to select between 9W or 11W of power consumption to leverage energy efficiency or performance.
