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.

HGST Ultrastar 7K4000 Review (HUS724040ALE640)

HGST's Ultrastar 7K4000 3.5" form factor enterprise-class HDD now ranges up to 4TB in capacity and spins at 7,200RPM while interfacing over SATA 6Gb/s. The drive offers the enterprise a 33% capacity leap over previous models, and it accomplishes that task of delivering robust capacity by utilizing five platters at 800GB each to attain the maximum 4TB capacity. This is a huge feature for enterprise customers who need to maintain the same footprint for their drives without increasing their costs. Another significant feature on the Ultrastar 7K4000 is that it is offered in Advanced Format which uses a 4096-byte sector size that is still backward-compatible with the 512-byte sector size. The HGST 7K4000 drive also features 64MB of drive cache.

Seagate Enterprise Capacity 3.5 HDD Constellation ES.3 Review

The Seagate Enterprise Capacity 3.5" hard drive line is the newly rebranded family of high capacity hard drives of which the Constellation ES.3 is the newest member. The ES.3 is a 7,200 RPM, 3.5" enterprise hard drive with SAS or SATA 6Gb/s interface that's offered in capacities up to 4TB. Seagate didn't just bring a capacity bump to the line though. Compared to the prior generation Constellation ES.2, the ES.3 offers a sustained data rate of 175MB/s, up 13%, and Seagate has doubled the cache from 64MB in the ES.2 to 128MB in the ES.3.

Seagate Enterprise Performance 10K HDD Savvio 10K.6 Review

The Seagate enterprise hard drive portfolio is getting a bit of a branding makeover, in this case the high-speed Savvio 10K drives migrate to the Enterprise Performance 10K category. We still know the drives underneath this umbrella by their proper names though, the Savvio 10K.6 being the subject of this review. In many ways, the 10K.6 represents a progressive step forward when compared to the prior generation 10K.5. The biggest highlight though is performance, the Savvio 10K.6 offers sustained throughput of 204MB/s, where the 10K.5 posted 168MB/s, a better than 20% increase. Such speed bumps are more than a nice to have. For many uses cases, like data centers want both performance and capacity in a high-performance storage tier, being able to move away from large form factor 15K drives and low capacity SFF 15K drives is a tremendous win.

Toshiba MK01GRRB/R 2.5-inch 15K SAS Enterprise Hard Drive Review

Toshiba launched the MK01GRRB series of enterprise hard drives at the end of last year. The 2.5" 15,000RPM 6Gb/s SAS drives are available in 147GB and 300GB capacities, making the MK01GRRB the fastest enterprise hard drive Toshiba offers in the 2.5-inch form factor. Toshiba isn't just about spindle performance with this family of drives though, they've also spent quite a bit of engineering to improve power consumption, further driving a better total cost of ownership.

Seagate Constellation ES Review (2TB)

The Constellation ES is Seagate's 4th generation 3.5" 7200 RPM enterprise-class hard drive. The drives come in 500GB, 1TB and 2TB capacities and support both SATA II and SAS interfaces. The Constellation ES isn't all about high capacity and performance though; Seagate's high on their power management and temperature tolerance for enterprise applications. The entire line also offers self-encrypting drive technology as an optional feature. With a spec sheet like this, it's hard to imagine wanting anything else in a high-capacity enterprise-class storage solution.
