Savvio 10K.5 shows 2.5-inch form factor benefits and earns RealWorld Labs award

RealWorld Labs spent time with the latest Savvio 10K.5 900GB enterprise drive and compared it against a 10K-rpm Toshiba model. The Savvio 10K.5 is built on a 2.5-inch enterprise form factor standard, which is designed to maximize performance density in data center racks while at the same time reducing overall power consumption compared to 3.5-inch drives.

Reviewer Nik Kastrantas found the Savvio drive, “…managed to surpass the Toshiba drives with overall ease in most tests.” Both drives were equipped with the latest 6Gb Serial Attached SCSI interface, which has become the preferred enterprise interface standard.

At a system-wide level, the benefits of 2.5-inch versus 3.5-inch are certainly clear, but individually 3.5-inch drives will typically outperform smaller form factor 2.5-inch drives. That’s in part due to physics as the 3.5-inch HDDs use larger, more powerful motors to spin the larger diameter platters. The result is slightly higher 3.5-inch drive performance, but that does come at a price. The larger motors are more power-hungry as well and therefore use more energy.

Kastrantas noted that the performance levels between the two form factor drives has changed with the Savvio 10K.5. “2.5-inch hard disk drives have finally managed to match the performance levels of their 3.5-inch brothers which automatically means less space requirements and electricity bills…”

Naming the Savvio 10K.5 among the best storage choices today, and citing the drive’s excellent price/capacity ratio, it received RealWorld Labs “Real Deal Editor’s Choice” award. Check out the review here and also do feel free to post a comment or question about 2.5 versus 3.5-inch enterprise drives.
