Samsung SSD 845DC PRO Review

The Samsung 845DC PRO is an enterprise-grade SSD designed to deliver high performance, especially in random write, and consistent low latency over the life of the SSD. The 845DC PRO has adopted the world’s first 24-layer 3D V-NAND technology for its storage, giving it up to 10 times higher endurance than conventional NAND. The drive has a cache memory up to 1GB, uses a Samsung3-core MDX controller and in-house firmware, SATA 6Gb/s interface, and boasts impressive performance numbers: sequential write up to 460MB/s and sequential read up to 530MB/s.

Samsung PM853T SSD Review

The Samsung PM853T is the latest entrant into the enterprise SSD space for the company. Like its sister SSD the 845DC EVO (they differ mostly in distribution channel), the PM853T leverages Samsung's TLC NAND and SATA interface. The result is a drive that's a capable alternative for entry-enterprise workloads that tend to be more read centric. The biggest draw however is not so much performance, though the drive excels there, it's drive cost that is the highlight. The PM853T gives the enterprise a solution that is cost effective enough with a performance profile and cost of ownership number that helps spell the end for high-speed 2.5" hard drives.

Samsung SM843T SSD Review

The Samsung SM843T is an enterprise-grade SSD that is designed to offer a consistent level of performance (99.9% reliable latency and QoS) over its lifespan, and is ideal for core enterprise use cases including Big Data systems, VDI and other high-performance enterprise platforms. The SM843T is a companion to the Samsung SM843 drive, which was originally reviewed approximately a year ago. Though both Samsung SSDs use the same MDX S4LN021X01-8030 Controller, the new SM843T is architected specifically for mixed data center use cases, while the SM843 is designed to be used in environments that require read-intensive behavior like server boot drives, higher-end enterprise client workstations and certain embedded applications. The other main difference between the two is that the SM843T uses enterprise NAND (eMLC), which focuses on prolonging the reliability of the drive, while the SM843 uses client MLC NAND.

Memblaze PBlaze3H and PBlaze3L Application Accelerator Review

Memblaze offers a dizzying array of configurations for PBlaze3 across 38 different capacities as part Memblaze's Pianokey technology. In addition to the MLC-based drives evaluated for this review, both drives are also available in SLC editions. Pianokey and other core components of the PBlaze3 platform are built with Memblaze's own proprietary technologies which is one reason to keep an eye on their emerging new product lines. One of the advantages that Memblaze argues for its products over comparable drives is that the card provides most of the computational and DRAM requirements for its operation, reducing PBlaze3's operational overhead to the host system.

Samsung SSD 845DC EVO Review

The Samsung SSD 845DC EVO line of drives are specifically designed to provide high performance and reliability--though cost-effective--solutions for today’s increasing data traffic in servers and data centers. Samsung indicates its new family of SSDs will deliver a very high level of sustained performance as well as consistent low latency over the life of the drive, giving it the ability to meet demands of increasing data handling. Under the hood, the 845DC Evo is equipped with Samsung's 19nm Toggle 3bit NAND, making it the first enterprise-class SSD to use TLC NAND. This new use of NAND combined with its MEX controller allows the Samsung 845DC EVO to be one more energy-efficient drives on the market, all the while maintaining the excellent performance.

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.
