KINGSTON
521A
mv91xx - OK
103424 K - OK

I'm assuming the mv91xx means I'm good to go on ACHI? I wasn't sure if it was working; in fact the Kingston Toolbox 2.0 and my BIOS don't even recognize the SSD, but it boots up and functions fine.

I don't plan on sending this back regardless; This is me just after a DOA Sandisk SSD post-blackfriday... These 70$/120GB SSDs haven't been working out for me!

mv91xx.sys seems to be Marvell (from the quick Google search I did), so you have your SSD plugged into a Marvel SATA III port.
You should be good to go unless it says 'pciide' in red/black letters. With AS-SSD, green is good and black is not good.

After discounts and a coupon I only paid $55, so im happy with it. Kingston really did a number on those unfortunate enough to receive the 5.06 update. Perhaps they can find a solution if/when 5.07 is released.

For reference, my WD Black 1TB HDD gets 85/READ 86/WRITE in AS SSD.

Well, I solved my issue. My ssd was on another controller, which was causing the speed issues.

I switched my ssd to the Intel SATA port and am now at 480 READ/180 WRITE in AS-SSD. If I run the compression test in AS-SSD I'm close to 500 on both READ and WRITE.

I received mine about a week or so ago from Amazon, and was lucky to receive the "good" firmware version. Grabbed it on sale for $69. It'd be worth it for someone to grab one from Amazon. If you get the wrong firmware just ship it back.

Low performance can not be explained away by firmware alone (which should be generic Sandforce firmware since only Intel and maybe Sandisk use custom firmware for their Sandforce drives).

Kingston switched the NAND Flash in the V300 to a cheaper lower-performance Asyncronous NAND after good professional hardware reviews were posted (V300 using Toggle or Synchronous NAND). Classic bait and switch.

Never buying Kingston again. That goes for their RAM as well.

Totally agree.
I am boycotting ALL their products.

i emailed kingston about this firmware version and slow speed issue, They replied me that i used the wrong software to test it with , bla bla bla.
Long story short , they know they are wrong ... they just don't want to do something about it.


Dear Nelly

Thank you for your reply.

Please note that the performance of the SSD should still be within the advertised speed, if it is not the case using Atto please provide me with screenshots using ATTO Benchmark.

Should you have any further queries, please do not hesitate to contact us again.

Warm Regards
Bala




Dear Nelly

Thank you for contacting Kingston Technology.

Please note that for the product SV300S37A/120G we specify the following scores as per our website; these are based on the drive being tested in an out of box state, using ATTO Disk Benchmark 2.41:

Sequential reads SATA Rev. 3.0 up to: 450MB/s

Sequential writes SATA Rev. 3.0 up to: 450MB/s

We state further that the speed may vary due to host hardware, software and usage.

In other words, if you are using different bench-marking software with the drive, you may get varying results which can give the false impression that the Dear

While ATTO Disk Benchmark uses compressible data to test the drive’s performance, AS SSD uses a mixture of either random or sequential and compressible or incompressible data. Lastly, Crystal Disk Mark defaults to using incompressible data, but this setting can be changed to benchmark the drive using compressible data instead.

SV300 is one of Kingston's value drives and in some cases we may vary components supply to keep the price target and a good availability.

There is however no significant performance variation between the different SSD builds.

Please use a bench-marking software which uses compressible data and a drive which is in a out-of-box state for an accurate reflection of the SV300 performance.

If you find that the test results vary greatly from those published, please do not hesitate to contact us, providing us with detailed information about the test parameters like a screenshot of the Benchmark results.

Should you have any further queries, please do not hesitate to contact us again.

warm regards
Bala


And if the speeds are correct only on atto , its still lying. Because in practice its not that fast. NEVER KINGSTON AGAIN. USELESS SUPPORT.
How easy can it be to just upload the other firmware on the website so we can downgrade it? thumb.gif

I guess I was lucky in buying the 240 GB version instead of this one. I just tested mine and got ~260 MB/s for read and ~220 MB/s for writes. Not impressive but it's good for what I paid for it. About 2.5X the performance of my existing 5400 RPM HDD.
