Overview

Ultrastar DC HC550 : High density storage

The Western Digital Ultrastar DC HC550 18Tb hard drive is especially dedicated to professionals for use in data centres. Indeed, this 3.5" hard drive for companies has many assets for a server use such as its RVS anti-vibration technology, a load of 550 TB/year and an MTBF of 2.5 million hours.

Available in capacities from 10TB, the DC HC500 Series can be used for enterprise servers, backup systems, cloud and enterprise NAS that require 4096-byte (4Kn) sector size for high performance and high density storage with HelioSeal technology.

Designed for data centres

The Ultrastar DC HC550 features multi-axis shock sensor technology that automatically detects and compensates for even the smallest shocks to protect the data stored on the Ultrastar DC HC550, and is equipped with RAID-specific features such as error recovery time that is reduced through the hard drive's error recovery processes. Ramp load/unload technology moves the recording heads away from the platters when the drive is not in use and when powering down, ensuring less wear and tear on the recording heads and media.

    Fast and good value for money

    Heats up less than the 1st one I bought 2 years ago (48° vs 51° after several hours of transfer, hard drive on usb dock so not ventilated). Recognised by my LDLC and inovu usb docks. Good transfer rate (190Mb/sec on average with peaks at 210Mb/sec, the 1st one I bought had peaks at 195Mb/sec and an average of 180Mb/sec but it wasn't the same source drive, and my configuration isn't new any more, core i7 4790K). Good To/price ratio (I took advantage of a promotion like for the 1st, it's a shame you can't choose in-store delivery any more). Generally quite quiet, but you can hear it scratching at times even if you're not accessing the drive (it's still noisier than the 22TB version that I also own). The ultrastars are very robust, I have 5 of them, one of which is 12TB and has been running 16/24 and 7/7 for 2 years and it's fine (remember to register on the WD site to benefit from the 5 year guarantee). Delivery a little long, ordered on Monday afternoon and received on Saturday morning (but during the promotional period, it's usually quicker).

    Good value for money

    It is very hot, 51° after a few hours of transfer (hard disk on usb dock so not ventilated). I've been using my LDLC usb dock for several years now. Good transfer rate (180Mb/sec on average with peaks at 195Mb/sec). Good To/price ratio (I took advantage of a promotion).

    Do the job

    The hard drive does the job, and silently. A few scratching noises the first day, then nothing. Time for all the innards to copy themselves and be in place.
    Then quiet, good throughput, low access time.

    Just the price is a bit prohibitive, but that's the case with all of them in these capacities... hence the 4 stars.

    Noisy

    I have an ultra-quiet setup (I only have 2 enclosure fans that I only hear when I turn up the power) and now I can hear this hard drive, accessing every 5 seconds, even if I don't access it myself.
    So for server use, as mentioned, I don't see a problem, and noise is certainly not a criteria. I've used all the SMART tools to test it (apart from the full 32+ hour test), there are no problems to report.
    I think this is the last platter hard drive I'll ever buy, large capacity SSDs are still a bit expensive, but the rapid drop in price will soon make old hard drives look like dinosaurs.
