Toshiba PX03SN Enterprise SSD Review (800GB)

The PX03SN is Toshiba's latest option for customers looking to take advantage of the rapidly evolving light enterprise SSD niche. The PX03SN a read-intensive enterprise SSD that leverages 19nm Toshiba MLC NAND for duties which require enterprise read performance such as host server storage and caching where write operations would total less than the PX03SN’s rated one full drive write per day. The PX03SN is available in capacities from 200GB to 1.6TB and uses a 7mm 2.5-inch form factor with a SAS 12Gb/s interface.

Micron M500DC Enterprise SSD Review

Micron today announced the availability of its new M500DC Enterprise SSD, a light-enterprise SSD designed and manufactured entirely in-house by Micron at a price point designed to make flash easier to adopt. Like its M500 cousin, the M500DC is built with Micron’s 20nm MLC flash and is offered with a SATA interface. The big change is the new M500DC increases the endurance from the M500, guaranteeing two drive fills per day for five years and a mean time between failures of 2M hours. The endurance figures are sufficient to deliver on enterprise use cases with fewer writes that still need advanced data path protection and features like power fail protection.

Samsung SSD 840 Pro Enterprise SSD Review

The Samsung SSD 840 Pro isn't a new SSD, it was released 18 months ago and targeted toward the client market. At the time, we did a complete review of the SSD 840 Pro and found it to be a very capable SSD for its targeted use cases. A funny thing has happened though over time. Web hosts and many others looking for a good SSD with moderate write endurance have been turning to the SSD 840 Pro. It's a lower cost alternative than duty-built drives designed for enterprise users and it still offers a good mix of performance and write endurance. This phenomenon isn't new, even hybrid and all flash arrays have been "guilty" of using client SSDs as their mainstay for many years. Despite the best intentions of the SSD vendors who would prefer enterprise users buy their enterprise drives, the cost equation sometimes wins out, hence the 840 Pro wiggling itself into more and more server deployments, despite its relative age and client focus.

Fusion-io ioDrive2 Duo MLC Application Accelerator Review

The Fusion-io ioDrive2 Duo MLC is a full-height half-length (FHHL) application accelerator that provides up to 2.4TB of capacity via x8 PCI Express slot. Fusion-io cards are notorious for their throughput performance as well as their low latencies, the combination of which drives some of the best responsiveness in the industry. Fusion-io's ioDrive2 cards are all fundamentally all the same, with hardware differences that differentiate. In this case, the ioDrive2 Duo combines a second controller and doubles the NAND pool compared to a standard ioDrive2. Fusion-io is also using MLC in this iteration, meaning users can get twice the capacity when compared to the SLC versions of the drives. Performance wise the MLC and SLC ioDrive2 Duo cards perform pretty similarly, the most obvious differences come in read latency, 68µs for the MLC and 47µs for the SLC, and endurance.

Seagate 1200 Enterprise SSD Review

The Seagate 1200 stakes a claim for the high-end enterprise SSD business as Seagate is part of the first wave of storage vendors to ship 12Gb/s SAS enterprise SSDs. The Seagate 1200 comes in 1.8-inch and 2.5-inch form factors, a 7mm z-height, and capacities up to 800GB. The 1200 series is a performance-oriented SSD the growing number of host platforms and applications which can take advantage of its 12Gb/s interface. According to Seagate, the 800GB and 400GB models can attain peak sequential 128k throughputs of 750MB/s for read operations and 500MB/s for write operations.

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.
