Kingston SSDNow V300 SSD Review – A Great Mix of Toshiba 19nm Memory and the SF-2281 FSP

ATTO DISK BENCHMARK VER. 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Our first look at performance is definitely a plus with high performance of 554MB/s read and 526MB/s write as compared to listed specifications which only seak to 450MB/s for both read and write performance.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or random data which is, for the most part, incompressible. In the V300, we have displayed testing using highly compressible data on the left, compared to that of incompressible on the right.

CDM results are still well above those listed by Kingston and we see a drop in write performance when testing in highly incompressible data which is typical of LSI SandForce Driven SSDs.  Although there are a few applications that might demand the highest result when transferring incompressible data such as music, movies and pictures, many seem to get caught up in numbers alone forgetting that the transfer of compressible data such as OS and application files always precedes that of the task at hand.

AS SSD BENCHMARK VER 1.6

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

AS SSD results relate much the same and we weren’t really impressed with the low Score, however, typically, we don’t rely on this alone. A quick look at the AS SSD Copy Bench below displays some excellent results and many believe the Copy Benchmark test might be one of the most important characteristics seen from this software.

  1. Les,
    What exact optimizations did you make in BIOS?
    Is there anything you recommend doing on a Gigabyte Z77 UEFI BIOS without disabling the SLEEP function?

    Thanks

  2. I’m having issues installing an operating system on the SSD. Doesn’t show up in diskpart or windows disk manager, tried it by external enclosure and swapping it out for my laptop HDD. Shows up in BIOS, but not in disk manager or diskpart when using windows 7 setup cd and windows 7 setup USB.

    It could be defective, but statistically most issues are human ones or hardware incompatibilities.

    • I am not sure where you have gone with this. Have you tried a simple install to check if the SSD was recognized during the W7 installation process? I have installed ….crap must be over a thousand W7 systems by now…and have never encountered a situation where the drive was recognized in the bios but not during initial installation.

  3. hello please how to tweak to get the final performance you did?

  4. Les, great article. One question though… why do you state “112 GB” after formatting? This is a continued misrepresentation of hard drive advertising. As you probably know, manufacturers sell drives using a base-10 system (1 GB = 10^9 bytes), whereas Windows sees the size with base-2 (1 GiB = 2^30 bytes), now known as “Gibibytes” or GiB to avoid confusion. This conversion leaves us at 111.75 GiB from 120 GB, what you call the difference due to formatting.

    • I apologize if I sound a bit frustrated but we explain things in a VERY simple way and using GiB does nothing more than to confuse the consumer CONSIDERABLY. It is a VERY simple method to explain the RAW total, advertised total and available total as we do, especially since 99.99999% of consumers haven’t a clue as to what you speak. They JUST want to know how much space is available. Thanks ahead Dan!

  5. I have two 120GB V300s.
    The first has 505 firmware which works at it should.
    The second has 506 firmware and is way slower.
    Could you check a new one with 506 to see if there are differences or is something wrong with mine?

  6. I think this review needs to be updated to reflect how Kingston changed the ssd from what they sent out for reviewing to what is being sold now. It’s a big story that this website should have caught onto but it appears not. Instead I shall share with you a link to some up to date information.
