Kingston SSDNow V300 (120GB & 240GB) Review
by Kristian Vättö on April 30, 2013 12:30 PM ESTPerformance vs. Transfer Size
ATTO does a good job of showing us how sequential performance varies with transfer size. Most controllers optimize for commonly seen transfer sizes and neglect the rest. The optimization around 4KB, 8KB and 128KB transfers makes sense given that's what most workloads are bound by, but it's always important to understand how a drive performs across the entire gamut.
As ATTO uses compressible data, SandForce based drives have an advantage due to their real-time compression engine. There isn't really anything surprising here as the V300 is on par with the other SandForce based drives. Read performance at smaller transfer sizes has never been SandForce's biggest strength but the write performance is strong at all IO sizes thanks to compression.

Kingston have the brand image to succeed in this market but their product lack the unique selling point. They are just commodities like their ram sticks.Kristian Vättö - Tuesday, April 30, 2013 - link
Which is exactly the point I was trying to raise. Kingston has a decent image and their distribution system is broad but their products are not unique. They shouldn't have a problem surviving in the market but they won't be able to grab any major marketshare either.UltraTech79 - Tuesday, April 30, 2013 - link
I don't think their goal is to grab major market share. Its to maintain and secure their current market share.Diagrafeas - Tuesday, April 30, 2013 - link
Which firmware did the drives have?I bought two 120GB ones a week apart.
The first has 505 and the second 506.
The 506 is way slower...even at booting Windows.
I'll post some numbers later...

The 120GB I have is 505. I don't have the 240GB anymore but I'm pretty confident it's 505 too as I received it a couple of months ago so it's not exactly new.Diagrafeas - Thursday, May 2, 2013 - link
Both are on SATA 2AS SSD Benchmark Scores 505-506(Read,Write)

On the second table - Kingston SSDNow V300 Specifications - performance drops as capacity increases, something that being correct is completely new in terms of SSDs. AFAIK in every SSD the higher capacity ones have the same or greater performance than lower capacity ones (of the same model, of course). C&P mistake?Kristian Vättö - Tuesday, April 30, 2013 - link
Nope, it's not a mistake (unless Kingston's datasheet is wrong):http://www.kingston.com/datasheets/sv300s3_us.pdf

The images on page 3 aren't working for me.Is there any significant difference in the msachi drivers compared to intel rst? Is it worth installing the intel ones when using an SSD?
