HGST Ultrastar Helium 6TB Enterprise Hard Drive Review

The Ultrastar Helium Platform (He6) hard drive family is HGST's latest effort to provide the next step up in capacity for enterprises that are faced with ballooning data volumes. The Helium drives are offered at a single 6TB capacity point, which offers a 50% boost over today's leading 4TB capacity offerings, and they are available with either a SATA or SAS 6Gb/s interface. The drives offer a spindle speed of 7,200 RPM, on disk buffer of 64MB and drive sustained throughput of 177MB/s. The fun technology part though is of course the fact that this is a sealed drive, with helium inside for reduced friction. HGST dubs this technology HelioSeal, which essentially reduces air disturbances caused by the disks and heads and allows for more platters to be sandwiched in the standard 3.5" hard drive form factor. The reduction in friction also means less power is required, 23% less at idle by HGST's measurements, netting cost of ownership benefits as well. HGST uses 7 platters, compared to four or five in most 4TB drives today, to drive the 6TB capacity in the Helium. Interestingly, this suggests there is more capacity up-side for the platform with more dense platters making Helium potentially a very compelling bridge to the next generation mainstream hard drives that will use HAMR technology (SMR has limited use cases) to increase density and drive capacity.

Seagate Enterprise Turbo SSHD Review

The Seagate Enterprise Turbo SSHD is a 2.5" 15K SAS HDD coupled with 32GB of eMLC flash that focuses on exceptional dollar-to-IOPS performance and capacity. With an estimated performance increase of 300% over a 15,000 RPM HDD, the Enterprise Turbo SSHD specializes in business-critical transactional environments (OLTP, VDI, SAP HANA), while also being considerably more cost-effective than a comparable SSD solution. The advantages of a marriage between HDD and SSD is made clear with the Enterprise Turbo SSHD: the performance and speed increases one would expect from an SSD, with a price point and capacity of an HDD.

WD Xe SAS Hard Drive Review

The WD Xe is a 6Gb/s SAS hard drive in a 2.5" 15mm form factor. The Xe drives spin at 10,000 RPM, offers a 32MB cache and provide throughput of up to 204MB/s. The drives are offered in capacities up to 900GB and a self encrypting drive (SED) option is available across the entire lineup. WD also offers an optional 3.5" bracket/heat sync that lets the Xe fit into legacy 3.5" environments, where they can be use to replace lower capacity and more expensive to operate 3.5" 15K drives.

Seagate Enterprise Performance 10K.7 Review

The Seagate Enterprise Performance 10K HDD v7 is a 15mm 2.5" form factor drive that ships in a 1.2TB capacity, interfaces over 6Gb/s SAS, and, as the name implies, spins at 10K RPM. The 10K.7 succeeds the Enterprise Performance 10K HDD v6, aka the Savvio 10K.6 that we reviewed earlier this year, and with the new 10K.7, Seagate aims to match high performance with low overall power consumption to deliver a reduced TCO to organizations deploying drives for data centers and cloud environments. On that note, Seagate quotes sequential data transfers at up to 204MB/s, which is aimed at meeting the marks of some 15K RPM legacy HDDs, and the average operating power rating is 8.02W with typical idle operation at 4.65W.

HGST Ultrastar 7K4000 Enterprise SAS HDD Review

HGST's Ultrastar 7K4000 is a 3.5" enterprise class HDD that ranges up to 4TB in capacity, features optional encryption and spins at 7,200RPM. The drive is designed for data centers, cloud storage, and backup and archiving. We previously reviewed the SATA 6Gb/s interface Ultrastar 7K4000 which made a splash when it was introduced due to its 33% capacity leap to 4TB as well as its 2 million hour MTBF and its solid 5 year warranty. This time around however, we're reviewing the recently released SAS interface Ultrastar 7K4000 which broadly features a lot of the same advancements as its SATA sibling. The Ultrastar 7K4000 SAS features optional encryption, up to 4TB of storage utilizing five platters (800GB each), and superb reliability figures with its MTBF at 2.0M hours.

HGST Ultrastar C10K900 Review

The HGST Ultrastar C10K900 is an enterprise-class, 2.5" HDD that interfaces over SAS, has a spindle speed of 10,000RPM and ranges up to 900GB in capacity. The Ultrastar C10K900 also comes in at a 14.8mm z-Height, classing it in the 15mm category. That small form factor helps to reduce organizations' overall TCO, especially in networked storage arrays or any space and/or power constrained environments. On top of that, other optimal environments for the Ultrastar C10K900 are blade and rack-mounted servers for applications such as online transaction processing (OLTP), any high performance scenario, and cloud computing.

WD Se HDD Review

The WD Se HDD is the company's latest 3.5" enterprise-class hard drive that ranges in capacities up to 4TB, spins at 7,200 RPM and interfaces over SATA 6Gb/s. The WD Se is designed to provide robust storage for large-scale NAS deployments, replicated environments, bulk cloud storage, and backup and archiving. The WD Se isn't geared toward revving up to the highest IOPS offered by an HDD; the drives are more affordable than performance variations and offer features required for data security by SMBs and the growing mid-range NAS market. That said, WD designed the Se series to still support moderate-workload applications with maximum sustained transfer rates claimed at up to 171MB/s.

Toshiba SATA HDD Enterprise 3.5" Review (MG03ACAx00)

Toshiba's new MG03 SATA enterprise 3.5" hard drives are now being offered as standard or encrypted models in the industry's highest capacity ranging up to 4TB while spinning at 7,200RPM with a SATA 6Gb/s interface. As we noted in our recent review of the MG03 4TB SAS, Toshiba has seen increasing demand for encryption and as such, they will now be offering it across all of their new models. As with the sibling SAS drives, the SATA drives offer a big jump in capacity to 4TB from 2TB as well as up to 18% faster sustained transfer rates and power consumption reduced significantly by up to 15%. Rounding out the enhancements, this new generation of SATA drives now interface over 6Gb/s SATA instead of 3Gb/s.

Seagate Enterprise Value HDD (Constellation CS) Review

The Seagate Enterprise Value HDD which is also known as the Constellation CS, is a 3.5", 7,200RPM SATA drive with a maximum capacity of 3TB that is targeted at organizations looking for the cost-effectiveness of consumer HDDs but also the enterprise features they need. The Constellation CS fit those needs by offering inexpensive bulk-storage for cases such as hosting unstructured data in the cloud with the lowest $/GB cost in the market. Adding to the Constellation CS drives' overall value is that at 2.75W/TB, it also offers the lowest power consumption of any new enterprise-class HDD, drawing up to 29% less power than competitive high-capacity enterprise drives by Seagate's numbers.

Toshiba SAS HDD Enterprise 3.5" Review (MG03SCAx00)

Toshiba's new MG03 SAS Enterprise 3.5" hard drives offer a 7,200 RPM spindle speed with top-of-the-line capacities up to 4TB and SAS 6Gb/s interface in either standard or encrypted (SED) models. The encryption feature is part of a push Toshiba is mounting to provide more security options across all new drives. The MG03 SAS Enterprise drives present a host of updates compared to the previous generation. Toshiba expanded capacities up to 4TB from 2TB, and the MG03 SAS drives now offer up to 18% faster sustained transfer rates while shaving power consumption up to 15%. Additionally, the drives offer cache buffers of 64MB, which is a significant bump from the previously offered 16MB buffers. The drives also offer error correction (ECC) for more reliability. All told, the lastest MG03 offering is on more even terms with other leading drives in the high-capacity enterprise SAS space and aims to be a viable option in a market long dominated by other drive vendors.
