Dell Latitude E4200 Info

There should be no reason for the Intel SSD to be slower than a HDD coming out of hibernation as it dominates a HDD in every single metric.

Not a great investment but should still be a lot faster.

 

Cheap MLC SSDs based on the JMicron JMF602 controller have serious latency issues that can cause problems when random writes are needed. SSDs based on the Samsung, Intel, or Indilinx controllers are fine.

 

@monakh

good point about the form factor, you are correct the X25-m will not fit in the 4200, I was thinking about the one i have in the E4300... for the e4200 you are correct and will need the x18-m

Not sure i agree at all with your point on SSD de-Hibernated delays.

I have a couple for testing at the moment, E4200 with 128gig Usata Samsung, E4300 with intel X25, M1330 with Intel x25, M4400 with Samsung RBX1 128 gig, and they all De-hibernate faster than with Hard disks.

My E4200 takes ages to wake up from hibernation, and don't even get me started on my MSRP $3000 XPS 1330 with Samsung Gen 1 SLC SSD. Heck NO

Just sharing my experience. You will find many who agree.

Do you all have 3+ GB of RAM? Perhaps that's a contributing factor?

 

4 gig in all machines except e4200 3gigs. all machines running window 7 RC - What OS are you running ?

My thoughts still stands in terms of SDD's the Intel ones are miles ahead of the rest.

 

On my e4200 with the 64GB Dell Mobility Drive and 1.3GHz SU processor, it takes a long time coming out of hibernation. I have 3 GB RAM, although that probably hurts since all that memory has to be backed up and restored.

On my E6400 with 4GB RAM and a 5400 rpm HDD, it comes out of hibernation quicker. But it has the P8400 CPU.

 

Hibernation should have very little to do with CPU speed and theoretically everything to do with disk throughput since all the data is saved to disk (unlike suspend which saves to the RAM).

I am on Vista 32bit. Not Windows 7. It is my understanding that MS has made significant changes to the sleep/standby functionality to make it work much, much quicker on Win7. I turned on my Win7 Phenom Desktop today from standby, it was LIGHTENING fast with my standard HDD. I was impressed! Can't wait to try it on my both my little Latitudes!

 

Just made some tests, to be sure:
E4200 SU9400 3G RAM 128G SSD Samsung Win7 7077, bluetooth and wifi on, SD card in dock:
From desktop to total stop, hibernating: 40 s
From hibernating to logon screen : 40 s + 1 or 2 s to have everything working

From desktop to total stop, normal stop: 35 s
From off to logon screen: 25 s + 4 or 5 s to have everything working

Even before tests, I never use hibernating mode. In the day, I use suspend in RAM, the depletion of battery is very low, and I stop for the night.

 

Exactly, so why would I use hibernation when Vista gets me a clean boot in about 5 seconds more? And if I am running XP, it would be in half the time, and hopefully, with Win7 it would be less than 30 seconds on a SSD. My Phenom RC1 is booting in about 30 seconds to the desktop with its 7200RPM drive. I am very impressed with the RC1's performance.

Edit, I just realized that bcoz's tests were done on Win7 B7077, RC1 is B7100, I hope it has made things better because 40-45 seconds out of hibernation on a SSD ain't anything to write home about. Perhaps, I will try it on my desktop and see how it does.

Nope. The Intel X25 Sequential Writes are about 72MB/sec, while, for example the VelociRaptor's are about 120MB/sec (I am doing this off the top of my head so don't kill me if the figures aren't exactly accurate). The Random Writes of the X25M are better by a factor of many times though. However, my point is that no, the SSD does NOT dominate HDD in every metric. Almost every metric but not all.

I disagree, at $325/Amazon (less if you use FleaBay with Live.com cashback), the X25 is an excellent investment considering current prices. It's expensive for a SSD but it stands heads and shoulders above the rest, especially with the latest firmware that fixes the weird quirk that PCPerspective discovered during their testing.

@chunglau

since we are talking about de-hibernate speed - would you mind running HDTach on your 64gig Mobility drive, (http://www.simplisoftware.com/Public/index.php?request=HdTach) just so we can get a comparison of your read speeds-

On the 128 gig drive, I get the kind of a strange curve - starts of at 60 MB/s rising to a max of 90 MB/s then dropping back to 60 MB/s - burst speed is around 100 MB/s - I wonder if the mobility drive is much lower ?
