Show us your SSD performance 2

[paulpicks21]

Just got my first SSD. Here's the benchmark. I'm a bit clueless why the write speed is so low though.

I bet you are enjoying your new super fast PC.

The low read speeds are most likely down to AS SSD. Try running the ATTO disk benchmark as it usually gives better results.

The lower write speeds are normal for certain SSDs - e.g. the Crucial M4. See the example below.

Despite the bad spelling - hideos (hideous) crysalis actually makes a good point. However this IS a performance/benchmarking thread where you want to show and compare scores

Right, for the OS, the focus should be on the 4K performance.

And so i'm clear, are we talking 4K or both 4K and 4K-64 thrd?

Thanks.

I would say mainly just 4k

The amount of threads these apps use are not a reality for real world use. Just check the cpu utilisation during those tests to see that you never see that kind of cpu utilisation when loading apps etc.

I manage very busy servers and even on servers I dont see queue depths reaching 32+. Usually 8-12 at absolute maximum.

That is a very interesting thread and a great SSD.

After following that thread for a while, the 830 will be my next SSD.

You won't be disappointed with the 830, my advice, try to wait and catch the 256gb model on sale for under $200, that's even more better lol

I've seen it for $179 once and I was tempted to snatch it up, that is an outrageous deal for that SSD!

 

[Dave76]

That is a great deal, especially since it's less than I paid for my first 40GB SSD.

I saw the cheapest 256gb SSD I have ever seen in the UK yesterday £99.95 ($160) for a Corsair Performance Pro 256GB 2.5" SATA-III.

I am amazed how low the prices are now!

Well I guess you better email me a pair of them.

Hi,

Because here eveyone are on SSDs and I'm still in HDD, I would like to put you a question

Anyone installed any SSD in a Toshiba Tecra R840 (win7Pro 64bit, 8GRam, I7-2640, 500GB HDD)?
I'm seaching for any incompatibility between this laptop and any ssd in the market!

Money is no problem, I really would like to have the most reliable one in my Tecra! (for speed it would be just a few sec more or less and that is not a big problem)!

Thanks,
paulo

I installed an OCZ Vertex in a Toshiba Laptop without any problems. I think any 2.5" SSD from any reputable make should work.

Hi whs,

Now I found good reviews in the Plextor M3Pro!!!

But I want a big drive and I would like to have your opinion because it seems that the big brother (512GB) is slower that the little one (256 GB)! Why this? What will perform best?

Regards,
paulo

 

[whs]

Can you link the 2 drives so that I can have a look.

The new Plextor M5 Pro is out and about now, and while it doesn't smoke the M3 Pro, it is using the new Marvell controller and I'm interested to see how Plextor works with that new controller. The M3 Pro had a few years worth of firmware revisions for the old Marvell controller, and the proof was in the pudding. Plus, the M5 Pro is on Newegg right now for $129.99, which is about $30 cheaper than the M3 Pro was when they carried it. I have a feeling the M5 Pro is going to be as reliable as the Samsung 830 and it already looks like it might be a shade faster.......just waiting until they have time to massage the firmware for the new controller!

As far as I can tell, the speeds are appr. the same. See in the links under 'Details'.

Well I've already said I'm not an expert
I saw that Random Read/Write speed IOPS are very different from the 256 and 512 model! Whats is the meaning of that?
512 GB model

Ran. Read Speed (IOPS 4K)
Up to 56,000 IOPS
Ran. Write Speed (IOPS 4K)
Up to 34,000 IOPS

256 GB model

Ran. Read Speed (IOPS 4K)
Up to 75,000 IOPS
Ran. Write Speed (IOPS 4K)
Up to 68,000 IOPS​

Correct, the IOPS are different. The MB/sec are appr. the same. In real life, you will probably hardly notice any difference.
