Servarica’s Polar Bear Storage: First Impressions

Published by Vyas Amar on

Introduction: Servarica Polar Bear Storage Plan

Servarica, a web hosting/ VPS provider from Canada, had posted their offers for Black Friday 2020 Low End Spirit and Low End Talk, among other places. A 2 TB storage plan for US $ 48 a year in particular piqued interest from a lot of folks, and the plan was sold out pretty quickly. I am posting a screenshot of the offer from their website, in case the page is taken down in the future. The link to the offer on LowEndspirit can be accessed here.

I had “won” a raffle on LowEnd Talk as a part of their Black Friday 2020 offers, and received a credit of US Dollars 50 from Servarica. I opted to use this credit for the Polar Bear Storage Plan. By then the plans were sold out, and I had to wait till the morning of December 15th when the opened up the plans again. Ordering and setup was smooth, and I was able to reinstall Debian 10 from the web based interface using the Debian 10 template.

First impressions of Polar Bear Plan

I ran the basic checks- Yet Another Benchmarking Script for disk and network performance and bench.monster for speeds or connectivity from home. The processor and network checked out fine. The disk speeds are rather concerning. I have decided to wait for a week before testing the performance again. Planning to raise a ticket only if the speeds are still unsatisfactory.

Update December 18, 2020: The disk speeds seem to have improved. I might run one more test towards the end of the year to check as the heavy users start winding down their uploading/downloading operations.Below you will find results from Benchmark test (YABS) run on this VPS.

I ran YABS with the flags to disable iperf and geenbench because I was more interested in the disk speeds.

Note the

-s -- -ig flags I added to the main command for YABS (i.e. curl -sL yabs.sh | bash).

The ‘i’ flag disables iperf, and ‘g’ disabled Geekbench. I was only interested in checking the disk speeds.
For Geekbench 4 and 5, as well as network connectivity, let us look at results below

Results from ‘dd’ test for disk speeds

I typically do not run this test since YABS is the preferred poison. But due to the low disk speeds, I thought of running this test.

Takeaways and First Impressions of Polar Bear Storage Plan

I liked the overall service, and the responsiveness (and friendly approach) of the provider. Once the disk speed issue is resolved, this storage server (VPS) can be put to use for backing up data for one or more of my projects.

This post is a part of a series of server and hosting services from Black Friday 2020 offers. This review is also indexed in the VPS Reviews and Benchmarks library.
