Silicon Power is one of the lesser-known SSD manufactures, however, that is not to say their products are not of good quality and good value. The Velox V55 is one of their more budget-oriented SSDs, with an alternative like the V70 aimed more for enthusiasts. Today we are putting the V55 under the test bench, so, let’s see how it performs…

COMPARISONS: We will be running our SSD COMPARISON ARTICLE after all SSDs have been reviewed individually. This comparison will compare all our SSD samples, so, this article will not contain any comparisons with other drives. We hope you return to read our full SSD comparison, to see which drive comes out on top!

The V55 is available in a number of capacities at 32GB, 60GB, 120GB, 240GB and 480GB. We are reviewing the 240GB of the V55 today, and we hope to bring you a review of the V70 very soon. After we finish reviewing all our SSD samples (and we still hope to bring you a review of the Velox V70, Seagate 600, Sandisk Extreme II and perhaps a couple of other SSDs) we will begin our SSD comparison feature, which will provide detailed comparisons between all the SSDs featured, and which is best for each market.

The V55 (240GB) advertises performance of up to 550MB/s sequential read and 440MB/s sequential write, however, the website states that the write figure was 480MB/s within ATTO. This SSD uses a very unique Phison PS3108-S8-I controller (a company we had not heard of). This controller is optimised for reliability, however, Silicon Power must have highly customised the firmware as the results highly exceed those usually associated with this controller. In terms of random transfers, the website quotes 80,000 random write IOPS for the 240GB model.

The NAND featured on the drive is made by an unknown manufacturer, however, it is claimed to be Synchronous TOGGLE NAND. The PCB does not shed much light on the manufacturer, and the cache chip is also of unknown capacity. The case in which the drive resides is made of plastic but feels quite sturdy. Remember, this is a budget drive so you cannot expect a fancy brushed metal finish on the outer casing.

Before we forget to mention, within the box which holds the SSD, we have, of course, the drive itself, alongside a 3.5″ mounting bracket, some screws and a user guide. The front of the drive casing features a sticker with some aesthetics, the name of the drive, various logos and the capacity of the drive. The outer packaging mirrors this design.

The Velox V55 is a very difficult product to find, however, we did find it on a German site for €177.90, which would work out at approximately £154 using today’s exchange rate (as of time of writing). This makes puts the drive at a price of just £0.64 per GB or €0.74 per GB, so, it is definitely on the budget end of the SSD drive at a very reasonable price range.

It’s time for some benchmarks. Again, please note, all comparisons with other drives will be carried out at the end of the feature in our SSD comparison article.

ATTO Disk Benchmarking Tool
ATTO is one of the most trusted and reliable disk benchmarking utilities available. The figures given by ATTO are the most accurate way of identifying the drives maximum capability if it were pushed beyond real-use limits and brought to theoretical maximum performance. The V55 achieved extremely impressive results for its price range, especially in 8192KB read!

8192KB Read – 548.20MB/s
8192KB Write – 479.02MB/s

32KB Read – 483.99MB/s
32KB Write – 412.22MB/s

CrystalDiskMark is one of my personal favourites in regards to drive benchmarking, as it often gives a very accurate figure as to how your drive will perform if it is pushed to its limit, whereas you usually will not be able to reach the figures provided in ATTO manually. CrystalDiskMark tests sequential speed, as well as a number of random read/write tests for 512K and 4K. The sequential read, random read & write and 4K-QD32 tests were all good for a budget drive, but the other figures fell a little short, particularly sequential write.

Sequential Read – 516.2MB/s
Sequential Write – 360.1MB/s

512K Read – 347.6MB/s
512K Write – 350.1MB/s

4K Read – 22.1MB/s
4K Write – 89.3MB/s

4K QD32 Read – 172.7MB/s
4K QD32 Write – 238.1MB/s

SiSoftware Sandra
SiSoftware Sandra is another tool used by many benchmarkers to see if the drive is consistent across multiple tests in different benchmarking tools. Sandra gives a very good indication of the real-life performance of the V55, which is a great performing mid-range drive for a budget gaming PC.

Sequential Read – 519.1MB/s
Sequential Write – 399.1MB/s

The Velox V55 has quite impressive speeds in most of the tests, but dips a significant amount in a few tests. Despite this, this drive is designed as a budget SSD solution and comes at an affordable price. This drive is being awarded our silver award.
