The Kingston SSDNow series is the first SSD that I’ve got my hands on for review, before starting Hardware BBQ. It wasn’t really a great drive (as with others since that’s when 1st generation SSDs were rolling out) but now when you look at it, SSDs have come a long way all thanks to the development of NAND and SSD controllers by multiple companies, some of which even being used as high-performance portable drives, like the SanDisk Extreme 500 and the 900 series. Usually, these units are considered as budget variants.

The Kingston SSDNow UV300 comes with a Phison controller, and this is the first SSD drive that I am testing with this controller. A 240GB is a fair amount of space for many users, but this should tempt a lot of people picking these up as they cost lesser than the mainstream high-performance counterparts. Question is that how does it perform with a bit older mainstream SSDs.

Kingston also emphasized in its page that it’s using TLC chips for this SSD. Opening up this SSD is a bit tricky. The security Torx screws are on the front, under the label. You’ll need to remove the label which will void the warranty. Speaking of which, Kingston provides three years warranty for this drive.

The top facing casing is plastic, the lower base is metallic. Kingston did a decent job of ensuring it’s of the same feel. There is a (thermal?) pad which is kept for the SSD controller, but it seems to have one-sided adhesive and has a rubber feel to it.

There is a total of eight Kingston labelled FD32808UCTI-B1 chips, a relabelled Toshiba A19 TLC.  There’s also a Nanya NT5CC128M16FP-D1– a 256MB DDR3L Cache chip. All of it is controlled by Phison S3110-S10-X eight-channel controller. Only one side of the PCB is used for the 240GB capacity UV300.

It will be interesting to see which performs better, a newer budget class or an older mainstream SSD drives, namely SanDisk Ultra II and Extreme Pro 240GB SSDs.


The system that I am using is to test most of the hardware. The same operating system, choice of USB 3.0 port (specific rear I/O port) version of benchmark software and the testing method is maintained throughout the graph.

Operating System Windows 10 64-bit Pro
Processor+ Cooler Intel i7 4790k + Noctua NH-U12S
Motherboard Gigabyte Z97X-Gaming GT
RAM 8GB Kingston DDR3 HyperX
Primary Storage 240GB SanDisk Extreme II SSD
Secondary Storage 3TB WD Red WD30EFRX
Power Supply Corsair TX750
PC Case Lian Li A70F

The testing methods are as follows:

Anvil Benchmark

  • Access Test
  • Transfer Rate Test

AS SSD Benchmark

  • IOPS Test- Sequential- 16MB, 4K and 4K-64 Thrd
  • MB/s Test- Sequential, 4K and 4K-64 Thrd

ATTO Benchmark- Read and Write

CrystalDiskMark Benchmark

  • 1 GiB- Read and Write
  • 32 GiB- Read and Write

Futuremark Benchmarks

  • PCMark 7 Benchmark
  • PCMark 8 Benchmark

IOPS Testing

  • 4K and 256K Read and Time- Total IOPS
  • 4K and 256K Read and Time- Average IO Response Time

SSD Access Test

  • Read: Min./Max./Average
  • Write: Min. Max./Average

Drive Format: NTFS

Access Test

Read Access speed is the lowest compared to the other two SSDs, but the write access speed is a lot for an SSD.

Transfer Rate Test

This test is done with incompressible data with 1GB file test. And still write performance is rather low.

IOPS Test

Transfer Test


Both AS SSD and ATTO benchmarks are in UV300’s favour.

1GiB Test

32GiB Test

With 1GiB, the performance is decent but it’s just another  story with 32GiB, the write performance is low.

PCMark 8 Benchmark

The pricing of all the three drives are as follows:

Kingston  UV300 240GB

India UK US France
 INR 5,900/-  NA  NA  NA

SanDisk Ultra II 240GB

India UK US France
NA £59.99 $79.99 EUR 82.99

SanDisk Extreme Pro 240GB

India UK US France
Rs. 9,532/-  £87.99  $94.99  EUR 104,60

For some very strange reason, Kingston UV300 is not available in any online retail websites except in Amazon India. Not even in France and not even in Newegg India. Strange is an understatement.

The cost of the Kingston SSDNow UV300 240GB SSD is Rs. 5,900/- IN which roughly translates to US$ 88.52 and the cost of SanDisk Ultra II 240GB is US $79.99 which roughly translates to Rs. 5,331.2 IN. Just because Ultra II is not listed in Indian retail sites doesn’t mean it’s not available. After all, I did get it from a PR right over here!

Taking everything into consideration, SanDisk Ultra II 240GB has a better random read and sequential/random write skills compared to the SSDNow UV300. Not a favourable position to be in. Ultra II is insignificantly cheaper, but it comes with three years warranty too but with better performance. UV300 needs to be priced lower so that it attracts buyers, especially for casual users who may not have a lot of write intensive tasks. Ultra II is pretty attractive for many types of users including gamers.

Budget series SSDs will have a tougher time to sell compared to older mainstream choice SSDs with better Sequential/Random Read/Write speed/access time when they come in the same price range. It’s an alternative choice, but there are many SSDs to look at before choosing this, which may include its own HyperX Savage SSD lineup, but I never got my hands on it.

  • Good Read Speed
  • Good Sequential Read Response Time
  • Write speed should be better for the  price
