Most Power Efficient SSD

Adding a 2nD SSD to my Sony Vaio Tz298 2.5" Sata very soon however I need a very power conservative SSD --> 80>120GB.Any recommendations ??

 

looks like you already picked a f120 but pretty much any ssd would work.

kingston or ocz or the c300

Not yet.It is in my plans.waitingg for someone else opinion.

The most power conservative SSDs are ones with Samsung, Indilinx or Toshiba controllers.

 

tx.could u give me some examples

 

Corsair Nova V128GB and Kingston V+ seem to have the lowest power consumption. I noticed a significant improvement when I changed SSDs from C300 to Kingston V+.

If V+ has great low power consumption then the regular V-series is exact opposite with horrible power consumption. I lost like 40 minutes or more (4:50 to 4:10) from battery life when switched from my Intel X25-V 40GB to Kingston V-series 64GB. So just a heads up.

I'm almost tempted to deal with the smaller space of the Intel for now until I can afford a better 60GB / 64GB SSD with better power consumption. Ironically the Kingston V+ seems to be the way to go!

edit: But then again I was just thinking about this, that's about 15% reduction in time, if you look at it as a direct proportion to idle power, the X25V @ 0.6W + 15% = ~ 0.7W so maybe it's not that horrible after all.

 

I couldn't find any review that measured the power consumption of the Kingston V series. But I saw Kingston lists it at 5.2 watt peak, which is very high.

If you want to make your battery last longer you could set the HDD power of time to 1 minute and set Firefox to cache to memory.

 

Firefox. I don't use firefox, despite what everyone raves I've had nothing but issues with it. That being said, good idea for power time, but won't it take a little bit (even a second) to turn on the SSD every time it has to access it? Seems like it would kind of defeat the purpose? Or is the SSD accessible with negligible access time when it powers on?

 

I don't know. Try it and you'll find out.

 

Phil what is the IOMETER GRAPH..?

 

It's the power consumption during the IOmeter benchmark. Quite a heavy usage scenario. It shows the power consumption under load.

 

I have the Kingston SSDNow on my Sony netbook - with 80% battery care running I can type in MS Word and open/scroll thru other reference files for almost 6.5 hours (display on dim, wireless off. Pleased with the upgrade. increased battery life by about an hour (again only charging up to 80%).

 

tx a lot.I've learned something else today.

Since my main concern is power drainage and based on some reading I have done I think the KINGSTON V+ will be my choice.

 

Checked prices of the KINGSTON V+ 128GB @ Newegg and found out that they carry two models >>

Any difference between them apart from $ ?

Same drive. The "B" version is bundled with a HDD enclosure and cloning software.

 

Phil, what do you use to measure power consumption and other stats of a running drive?

 

I don't measure power consumption of the SSD. I only measure battery life of the whole notebook with Batterybar 3.4.2.

 

See the Tom's Hardware 2009 SSD charts and 2010 SSD charts. They include specific power consumption measurements under different usage conditions.

I believe the Kingston V+ is a rebadged Toshiba.

Interesting, no Kingston V series.

 

I want to bring this back for a minute. I'm having a hard time finding power consumption specs and testing for the GSkill Phoenix Pro FM-25S2S-60GBP2. I've found numbers from reviewers saying it's very power efficient and then there's this article which says it uses 8w while active?!

There aren't any #s on Gskill's website or Newegg and I'm going through the SSD thread now to hopefully find one of Phil's tests with it vs a few other drives.

I'm looking at the Corsair Nova 64 as well. Either drive would be boot only w/Win7 x64. Gskill seems super fast but is a ? for power (battery life is important) while the Nova is top end of power consumption but maybe slightly slower overall.

 

It will be similar to all other Sandforce drives, it's definitely not 8W though. The Nova would definitely have better battery life with it's Indilinx (or is that the Samsung, either way though still less power consuming than Sandforce).

 

Power consuming specs are a bit tricky. While active one may read more power draw than another but if it is faster it may not be active as long. So at first boot it may have appeared to draw more power but down the line it may actually prove to be a better option even though its power draw ratings are higher.

You really should stay away from the specs and look more into real world experience from systems that will typically be used like yours will. I'd trust real world usage over specs and or a watt meter any day...........

 

That's plain wrong. Check Tomshardware, they've measured many SSDs, maybe even this Gskill.

I saw the GSkill deal. It is super fast, unless you write a lot of compressed data (images, movies, music).

 

Phil, do you have any first hand experience with the Corsair Nova and it's power consumption? Kingston V+ seems like an excellent notebook drive, but it's not price competitive at all. Corsair Nova seems next best.

 

Unfortunately I did not test it long enough to have a real accurate answer.

In the test I did do, Samsung 470 came out better than the Nova.

 

Phill , what is this new Samsung SSD? i thought the performance on all them was very lousy...
