I saw a few posting test results, here are just the Enabled RAPID mode as PRE RAPID is pretty much the same as everyone else's.

A couple things I noticed:

-Tests run better if you run them separately (i.e. Seq, then 4K as opposed to all at once)
-I have a HUGE difference on 4K-64Thrd. Do you think this is due to the CPU-RAM config? 2600K with Kingston's 32GB Hyper Beast running at 1921 MHZ (a little OC). DIMM timings have not been altered.

Didn't work with SATA 2 port with Windows 8.1

Max Performance tweaks in SSD Wizard and Rapid mode enabled
Sequential Max Read = 230.51MB/sec
20% overprvisioning
191.87MB/sec sequential write speed
128GB Samsung 840 Pro
----------------------------------------------
MAX Reliability settings with Rapid Mode OFF
238.47MB/sec read
189.90 MB/sec write
28.06MB/sec 4K read
46.04MB/sec 4K write
score 294

why won't it work with SATA 2 ports?
Did I break it already?

@Bullwinkle: The 840 Pro is a SATA 3 drive.

Max bandwidth throughput for SATA 3 is 600MB/s.

Max bandwidth throughput for SATA 2 is 300MB/s.

SATA 3 was designed to be backwards compatible, so other than decreased performance there shouldn't be any problems.

Windows 8 has built-in TRIM support for SSDs:

1. Right-click on the Start button and select Disk Management

2. In the Disk Management window, right-click on the SSD and select Properties

3. In the Properties dialog, go to the Tools tab and select Optimize

4. In the Optimize Drives dialog, select the SSD then click Optimize.

5. Click the Change Settings button to have the disk optimized automatically

thats really strange.

maybe your sata2 port is old and isnt compliant?

No IDE for you?

Looks to be for AHCI only

oh well, I guess 3 second boot times will have to be good enough

avatar

The Mac

yes, its AHCI only..

no raid, no ide.

Any particular reason you are running in IDE Mode?

avatar

Bullwinkle J Moose

Why IDE?

I like complete compatibility with all my old XP backups instead of knocking another fraction of a second from my 3 second boot time by breaking compatibility in AHCI mode or running to the BIOS every time I boot something new

IT's FAST ENOUGH!

Really
I ain't kiddin
Usually I am, but not this time

avatar

The Mac

why would AHCI break you restores?

ACHI doesnt change the disk geometry, its still MBR anyway you slice it.

avatar

Bullwinkle J Moose

If you make IDE backups, they only boot to IDE Mode

Why change it now?

So I can run to the BIOS and waste time fixing it every time I boot something new?

IDE works

Give me a good enough reason to change every backup I have by reinstalling everything in AHCI mode and making new backups

Fast enough is fast enough and I can live with that
Can you?
---------------------------------------------------
Update:
Reinstalled Windows 8.1 in AHCI Mode
Enabled all Performance tweaks and Rapid Mode in Samsung SSD Magician
I now get better numbers but the computer isn't any faster
In fact, it went from a 6 second boot in IDE mode to a 33 second boot in AHCI

AHCI Numbers>
Seq read 341MB/sec
seq write 410MB/sec
4k read 28.24
4k write 148.66
4k64thrd 279.64 read
4k64thrd 509.40 write
score 1230

Better numbers but no perceived speed increase
In fact, a MUCH Slower boot time in AHCI

Looks like IDE Compatibility Still Rules!

Unless anyone can show me an actual benefit in the real world instead of just numbers proclaiming a massive benefit, I will stick to what works

To me, this is just snake oil

This software really boosted my 840 Evo 250 gig performance. It would be interesting to see the effect on the Pro model.

no RAID support? what a crock

bjoswald

Just installed on my 128GB 840 Pro. Will see how it works out!

I read an article that tested the drive with RAPID both on and off in a wide variety of applications. They found there to be little real-world gains, or even a hit, in most applications when RAPID was on.

avatar

John Pombrio

I saw a difference, enough to notice it and swap from a Pro to an EVO because of it. I expected it to not do anything useful but for my simple needs, it really did work faster. That was a nice surprise.

I have a pair of 840 Pro's in RAID 0 and I found that you can not use it if you have the drives configured in RAID.

avatar

John Pombrio

Or even if they are not. The Magician software says that only one SSD drive can support RAPID even if you have two installed, RAID or no.

avatar

The Mac

Just installed it on my boss' 840 pro this morning.

Seq read went from 512, to over 1000.

We will see how it performs in the real world.

If you get the "Magician was unable to find a Samsung SSD connected to your system. Some Magician features may not work correctly." error there is hope. I have a 512GB 840 PRO, just called Samsung and they said this is a known issue and is in the works of fixing it with an update. They said just rollback to the last version of Magician and wait for the update.

So they are aware of the problem (if you have them) and are actually working to fix it WITHOUT giving people the run around (was on phone for 3 min tops).

My gut reaction here is that this is not a good thing. Windows already caches frequently used files in memory for faster access. It sounds like Samsung is replicating this functionality so that it can claim that it has made its SSDs faster, when in fact it has only displaced an OS function.

When everything is running correctly the amount of content stored in cache as reported by Task Manager in Windows 8+ should be about equal to the amount of free memory you have.

I have difficulty imagining how Samsung could make this situation better.

I have both the Samsung 840 Pro and 4 840 EVOs in 256GB sizes. I moved from the Pro to the Evo becuase there was a NOTICEABLE difference to me in boot speed and program loading when I started running the Rapid program. It DOES work and works well. Then I gave my son the 840 Pro. Should I get it back now that it supports RAPID? heh.

avatar

The Mac

i would, the pro is more robust. It uses standard MLC

The Evo uses toggle Nand, it has a shorter lifespan.

John Pombrio

Thanks Mac, I did not think about that. Its unlikely that I will ever wear out an SSD drive. I am upgrading SSDs about every 9 months now for the past 2 years. Nah, Justin runs Linux and that will not support RAPID anyways so he gets the Pro.
