Kingston SSDNow V300 (120GB & 240GB) Review
by Kristian Vättö on April 30, 2013 12:30 PM ESTTRIM Performance
SandForce has always had trouble with TRIM. SandForce's approach of compressing data on the fly definitely complicates things and I believe it's at least partially the reason why TRIM behaves the way it does in SandForce based SSDs. Even though TRIM doesn't work perfectly in any SandForce SSD, there are differences between drives and some do better than others.
As usual, I took a 240GB V300, secure erased it, filled it with incompressible sequential data and then tortured the drive with incompressible 4KB random writes (QD=32, LBA space 100%) for 60 minutes. I then ran AS-SSD after the torture to get dirty-state performance. Finally I TRIM'ed the drive and reran AS-SSD.
| Kingston SSDNow V300 Resiliency - AS-SSD | |||
| Clean | After Torture | After TRIM | |
| Kingston SSDNow V300 240GB | 278.2MB/s | 204.7MB/s | 257.6MB/s |
And the issue still persists. For the most part, this isn't a big issue because the majority of users won't store just incompressible data in their SSD (e.g. Windows is very compressible) but if you know you'll be storing lots of incompressible data (H.264 videos, MP3s or encrypted data), then going with something non-SandForce is a better option.
Power Consumption
In terms of power consumption, the V300 does pretty well. It doesn't break any records but for example Corsair's Force GS draws more power in all of our tests. The utilization of smaller process node NAND (19nm versus 24nm) does have some impact but I wouldn't be surprised if Kingston's customization also has something to do with the lower power draw.

At least for me they are working fine at the moment (tested on my desktop and laptop). Can you try a different browser? We had some issues with our image server earlier today, although it should be fixed now.Intel RST drivers provide a bit better performance and are hence recommended when using an SSD.

Cool, thanks! And the images are working for me now on all browsers.Diagrafeas - Tuesday, April 30, 2013 - link
Don't the latest drivers get installed with INTEL Inf Update Utility?Do i have to download something else?

Images not loading in Windows Chrome v26.0.1410.64m or IE9. Hitting "Click for full size" produces the error: "Internet Explorer cannot display the webpage... Diagnose connection problems"http://www.youtube.com/watch?v=dXREEVpjloo

Yeah, not loading for me either. Anand is on it.GuMeshow - Tuesday, April 30, 2013 - link
I was about to post about that too ... Firefox doesn't load images from images.anandtech.com either.Slash3 - Tuesday, April 30, 2013 - link
I'm enjoying the new Imagination Viewing mode on AT, I get to create all sorts of great article pictures in my head. :)omarccx - Tuesday, April 30, 2013 - link
Pictures aren't working for me, either. :(HisDivineOrder - Tuesday, April 30, 2013 - link
Sandforce drives are boring.Could have summed this up with, "If it's a Sandforce drive and it's by someone other than Intel, look at any other Sandforce drive's review and consider a 5% variance up or down. The end."
See, I can review any Sandforce drive by doing this. Where's my checks, Anandtech? This was hard reviewing I just did here. I reviewed every Sandforce drive based on SF-2281 on the market in the last six months. That's a lot of checks I'm owed there. You feel free to swap out the brands and models on the drives and what not so they all fit.
Also feel free to pay me in Samsung SSD's. You know. Actually interesting SSD's.

Just dont go by the branding. Kingston uses SandForce controllers - SF-2281 which are very proming & thats why Intel is bundling their SSDs with SandForce controllers & believe they are amazingly solid in terms of performance & reliability. Initially most of the SSD makers had issues with the controller maker - SandForce due to firmware compatibities which are now totally resolved.
