And while I’m already at the topic and my test setup is up and running, I also had a go at two of my 2.5″ 4 TB drives and their read and write performance when running differential backups that contain large 50+ GB files, many files in the range of 2-3 MB and many more … Continue reading HDD Performance – Part 8 – 2.5″ 4TB Drives – Reading and Writing
The proof lies in the pudding, they say. I’ve initially started this hard disk read and write performance marathon, because the perceived speed of some of my backup hard drives when performing differential backups to them was very slow. Despite being differential, such backups easily go beyond 1.5 TB. So after establishing read and write … Continue reading HDD Performance – Part 7 – Differential Write Performance
Wow, this is part 6 of the series already, but I keep getting interesting results. One of the questions that came up during part 5 was how fast data could be read from one of the newer and faster drives when the drive is almost full. To answer this question I ran the following test: … Continue reading HDD Performance – Part 6 – 16 TB Write then Read
In my HDD performance analysis series, I would now like to move on and have a look how fast my ‘real world’ data on my backup hard disks can be read. At the moment, I have around 7 TB of data on my backup drives, which consists of a significant amount of very large virtual … Continue reading HDD Performance – Part 5 – Reading 7 TB Real World Data
And on we go with another round of looking at Hard Disk Drive performance. After writing 50 GB files to a number of hard drives in episode 2, I decided to have a look how the drives would perform after randomly deleting some about 2.5 TB of 50 GB files and then fill up the … Continue reading HDD Performance – Part 4 – Writing Large Files to Empty Spaces
In part 1 and 2 of this series, I’ve had a first look at the performance of a number of different hard drives I use to back up large amounts of data. I currently have around 8 TB of data that needs to be backed-up regularly, so speed is of the essence and decides whether … Continue reading HDD Performance – Part 3 – Measurement Setup
In the previous post on this topic, I had a closer look at the write performance of the best backup hard drive I had in stock at home. I bought that drive recently, because I was running out of space on my other drives and because they somehow did not seem to behave as snappy … Continue reading HDD Performance – Part 2 – Huge Files Write Performance
My data heap keeps growing and I do have a good multi-layer and multi-location backup strategy. Offline and off-site storage is the motto of the day, which requires hard disks with large capacities so data can be physically moved. So far, I used several 8 TB hard disks to which I would sync the data … Continue reading HDD Performance – Part 1 – Huge Files on a New 20TB Drive
Over the past days I’ve been experimenting a bit with SSD’s, traditional spinning hard disks and hybrid drives (SSHDs) to see how big the differences are between them when it comes to everyday tasks. To my surprise, the hybrid disk performed much better than I thought.
So far, the public cloud has pretty much been ‘virtual machines’ for me, with varying numbers of CPUs, memory and storage, depending on the application. Recently, however, I’ve been looking for a way run copies of my home cloud based virtual machines (VMs) and Docker containers in a data center for redundancy purposes. For this … Continue reading Bare Metal in the Cloud – Part 1 – Let’s Rent Hardware
