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.

Intel SSD DC S3500 Enterprise Review

The Intel SSD DC S3500 is designed for data center applications such as in cloud computing, web hosting and other read-intensive environments, and the drive features an in-house controller, 20nm MLC NAND, and form factors at both 2.5" and 1.8". The DC S3500 is the latest SSD in Intel's new line while its sibling, the DC S3700 that we've also reviewed, is designed for the mainstream and high-performance enterprise market segments. These SATA 6Gb/s interfacing drives both take on the new four-digit naming convention Intel is incorporating to give more clarity and distinction to which drives belong to which category (consumer, pro, enterprise).

Toshiba PX02SM Series Enterprise SSD Review

Toshiba's PX02SM is a high performance enterprise-class SSD that features eMLC NAND with capacities up to 1.6TB as well as a new dual port SAS 12Gb/s interface. The PX02SM updates the Toshiba MKx001GRZB Enterprise SSD that we reviewed which was previously Toshiba's pinnacle enterprise SSD with 32nm SLC NAND and SAS 6Gb/s in a 2.5", 15mm form factor. This time however, the Toshiba PX02SM comes to market in a 2.5" form factor that has been slimmed down from 15mm to just 7mm (still 15mm for the 1.6TB model). Additionally, Toshiba has chosen to implement eMLC NAND, attaining comparable endurance and even greater cost-effectiveness, yielding lower prices for organizations' IT budgets.

OCZ Talos 2 R Enterprise SSD Review

The OCZ Talos 2 R is a 2.5" form factor enterprise-class SSD that ranges in raw capacity up to nearly 1TB and features a SAS interface with dual-port support as well as cost-effective MLC NAND. The Talos 2 R also features OCZ's Virtualized Controller Architecture (VCA) 2.0 that ties together a pair of SandForce flash controllers to deliver performance and capacity enhancements. This much makes the Talos 2 R similar to its sibling OCZ Talos 2 C that we recently reviewed. However, the Talos 2 R differentiates itself from the Talos 2 C by tacking on power fail protection to protect in-flight data from unexpected power loss, an upgraded controller and additional over-provisioning at 28% versus 7% on the Talos 2 C.

Micron P320h 2.5" PCIe Application Accelerator Review

In March of last year, Micron announced a new 2.5" form factor for their P320h application accelerator card. PCIe cards have been the de facto standard for any enterprise looking to drive maximum responsiveness from their storage. The form factor does suffer though from issues that don't bother traditional 2.5" and 3.5" form factors such as hot swapability. It's rarely practical to power down a server and remove it from a rack to service the storage inside. Thus, the 2.5" PCIe form factor enables the speed that the PCIe interface can deliver, with the serviceability that standard drives offer. Of course a new interface means little without server support, and as part of the announcement from Micron, Dell stepped up with server support for the new drives in many of their 12th Gen PowerEdge servers. The Dell servers, like our Dell PowerEdge R720 12G with Express Flash (Dell's branding of 2.5" PCIe), offers up to four 2.5" P320h drives accessible by standard access in the front of the server via a specialized backplane.

Seagate 600 Pro Enterprise SSD Review

The Seagate 600 Pro SSD is a 2.5-inch MLC NAND enterprise-class SSD in a 7mm form factor with a capacity up to 480GB that is designed for read-intensive applications. Due to its size, the 600 Pro easily fits almost any platform, maximizing capacity while minimizing its footprint. Seagate's primary focus during the engineering of this drive though was to build a drive to meet the growing demand within the enterprise for SSDs that offer enterprise-class endurance and adequate performance at a reasonable price-point. Organizations that need these types of drives include centers, cloud system builders, cloud service providers or virtualized enterprises. In these applications, the enterprise requires more endurance than they could get with a client SSD; it wants a drive upon which it can depend to be reliable over time, thus keeping data secure.

SMART Storage CloudSpeed 500 Enterprise SSD Review

The SMART Storage Systems CloudSpeed 500 is an entry enterprise SSD  with SATA interface designed to meet the needs read-intensive scenarios such as boot drive, workstations and certain embedded applications. The CloudSpeed 500 uses a SandForce controller paired with 24nm MLC NAND to deliver not just high throughput, but also high endurance. It can be difficult to differentiate with SandForce-based SSDs, as the build and firmware are rarely novel. With that in mind, Smart's hook with the CloudSpeed 500 is the endurance. Smart touts 15,000 PE cycles, which is more than some other SandForce-based offerings, and it does this all while preserving capacity with just 7% over-provisioning. The drive also offers power-fail protection to ensure in-flight data makes it to its destination during a power loss event.

OCZ Deneva 2 Enterprise SSD Review

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. 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. The Deneva 2 also comes in two different series to provides users flexibility in their choices. 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. Our test model is the OCZ Deneva 2 R eMLC NAND 200GB capacity drive. One more design note is that architecturally, the Deneva 2 comes in a 2.5" form factor, but OCZ can tailor it per application.

Micron M500 Enterprise SSD Review

The Micron M500 is part of the new SSD family created by Micron and Crucial geared toward personal storage applications with the Micron M500 slotted as an enterprise-class SSD that ranges in capacities up to a robust 960GB, uses 20nm MLC NAND, a Marvell controller, interfaces over SATA 6Gb/s, and features a slim 7mm drive height. The Micron-branded M500 is also targeted at Cloud and Web 2.0 segment. As we mention in our review of the near-identical consumer-oriented Crucial M500, the Micron brand is established and is known for its long-term reliability and its compatibility. Adding to that is the robust capacity and value offered by Micron. On that note, while Crucial's M500 offers top capacity in the consumer-market, there are existing enterprise SSDs that meet and exceed 1TB. Yet, what Micron brings to the table is affordability. While other drives might range up to $4,000, the Micron M500 960GB comes in low at less than a quarter of the price.
