Three 2.5" SAS Drives: Enterprise Data Giants, Compared

Features
By , published

Currently, 2.5" enterprise drives are leaving their 3.5” competitors behind. They're faster, more flexible, and now they offer comparable capacities (we're up to 1 TB now). In this piece, it's Hitachi versus Seagate battling for high-density supremacy.

Benchmark Results: PCMark Vantage

Strictly speaking, PCMark Vantage benchmark is not intended to measure the performance of enterprise hard drives. Nevertheless, we included it for the sake of completion.

    Toms with some more review niceness. Thanks for another interesting article. I don't think mechanical storage is going anywhere soon. For better and worse we'll still have it around for a long, long time to come. Even when SSDs hit that magical speed/capacity/cost point to be ubiquitous for mainstream consumers, enterprises will still need HDDs as part of their storage needs. HDDs are at least a known quantity that are still getting better.

    3rd paragraph: "have to be taken into considered". You also didn't mention capacity and cost/GB, where mechanical disks still reign supreme.

    Also, why not benchmark a 3.5" disk, but only use the outer portion. If both that and a 2.5" have the same density and rotational velocity, then the 3.5" should win due to higher I/O speeds resulting from higher linear velocity.
