Still, impressive results...hell of a drive though only on FX 6300 @ 3.8 and SB950...

No, Device manager shows MS, But AS SSD is still AMD???
Did the following 2 minutes apart just now




Since my last post I used Samsung SSD Magician to over provision, but it gave the disk bad offset alignment (why???) and again, bad peerformance. So I had to use Paragon Alignment Tool (3.0) to fix that. All is well again.

Here are the results for my 840Pro and 840... Not quite what I was expecting, but could the missing Acc.Time(I get a cannont find physical drive error on that one) lower the score that much?





*Edit* Billb, you look like you're in Disk Drive drivers, and not sata. Go to the section in Device Manager that says IDE ATA/ATAPI Controllers. That should be where it says AMD Sata.

To be honest I had higher performance with the AMD SATA driver than I did with the MSAHCI one. When my 840 120 arrives I will retest to make sure. I don't have an SSD right now because the 830 I got was an OEM version and it's been returned to the shop.

I would like to know what CPU speed has to do with SSD performance. Does it make a difference at all and if so how much?

The prices will always drop. If you aren't in a huge rush, I'd say wait for a sale, but waiting months and months for the price to drop doesn't make a ton of sense since then there will probably be something newer or faster about to launch.

I also expect to be building a haswell machine around then, don't wanna stack too many purchases at once lol, but that's just me.

Hi guys.

Just read the ad:
Samsung’s SSD 840 PRO Series is a high-performance SSD, capable of delivering up to 100,000 IOPS Random Read Speed and 540MB/s Sequential Read Speed—an SSD of unrivaled high performance.

What to say, I am Samsung fan, their products are just fine, I own the old SSD 470 64GB and I am interested in what new series can offer, those 100,000 IOPS caught my eye.
Primarily I need very fast seek times.
On my 'Bonboniera' laptop Everest reports 36.5MB/s 4KB Random Read, and 0.22ms Seek Time.

Looking on 840 model and its 0.075ms I wonder whether my 36.5*1024/4 = 9,344 operations per second will become 3*9,344?
Also the ad says 100,000 IOPS but my dummy calculations predict 28,000, am I missing something else?

Are there usually online boxing-day sales for Canadian retailers?

As Darius Silver said above, you have to check at IDE ATA/ATAPI Controllers, not Disk Drives.

There you can find the AMD Sata Controller as i said in my previous post.

If you want to compare performance between drivers, you''ll have to uninstall that driver, so that the system uses the MS one.

Before doing so, please write down the version of the AMD driver, if you can.

I just picked up an 840 non-pro 250gb drive. And am fairly impressed with it. The drive is for an older box that has an asus p67 pro mobo with 2125 cpu.
