QuickWeb Supa V8 VM2 (SSD) Review – Very Fast!

Last week we wrote about the QuickWeb Supa VZ1 VPS, which sported some amazing results for the price. However, like we mentioned before in the review, we wanted to give you the feeling of how fast their SSD VPSes are. I will tell you right from the start, these VPSes are some of the fastest I have ever used. They're really fast... and I mean it!

As we already introduced QuickWeb in our former review, let's just get straight on to the review.


The QuickWeb Supa V8 VM2 VPS is quite the bargain for how much you get. For $15 a month, it will give you 512MBs of RAM with 768 swap, two CPU cores, 8GBs of SSD storage, 500GBs of bandwidth, and a 100Mbit port speed (which is actually less than than the Supa VZ1 I have). Of course, granted the price of SSDs nowadays (okay, they are not as much as they were a year ago, but they are still a good chunk of change), you do see some limitations compared to the hard disk based VPSes, like a lower port speed and less storage.

Although I would say for $15 a month, you are getting a great VPS for the money.

Network Speed

As the SSD can download data very fast to storage, I decided to download to the disk than to sending it off to /dev/null. The results are quite amazing.

83mb/s is incredible for a VPS! And as there is indeed less storage on a SSD, I am sure these nodes will be a little bit faster overall as QuickWeb cannot fit as many users as they can with the space hard disks offer.


SSD Speed

If you are looking to buy an SSD VPS, you are most likely doing it for the speed. This QuickWeb SSD VPS troops quite a bit!

One might say that 186mb/s a second isn't that much for an SSD compared to RAID, but if you think about it, this is one drive, not four or five drives combined together (RAID)! Not only are the dd results impressive, but the I/O ping is amazing at a nice 16.7mb/s a second (the VZ1 VPS got a low 0.4 mb/s). That's like 40x faster compared to the RAID config! Hot damn that's good! :P


CPU Performance

We know what you're thinking! How's the performance on this baby? As there is one more CPU core on this VPS than the VZ1, I'm thinking it'll do better. Let's see!

As you can clearly see, the score is about 1.4x faster than with one core. Logically, you would of expected 2x faster, but technology isn't that persistent. Never alas, it's for sure something to not complain about; that's a very fast VPS right there! We have to test the UnixBench scores though to see how it can stand up with consistent load. This should be where the differences are.

With the UnixBench being 1.8x faster than the VZ1 VPS, I'd say the extra processor sped up the VPS by nearly two times, which realistically should happen. The performance for a two core VPS at only $15 a month is not bad at all!



I am very impressed with QuickWeb's v8 VM2 VPS; it well exceeded my expectations on a high-performance VPS. If you are looking for a VPS that will handle database heavy applications with consistent load times, QuickWeb's v8 VM2 VPS is for you! Hard drives might handle sequential reads very nicely, but these SSDs can handle random I/O way better than anything else can!

Overall, I give this VPS an A+ on everything. Despite the slower port speed, it is ironically faster than the one gigabit line as well; I guess that's an SSD for you!
