Samsung 840 non pro oem slow sequential write on lenovo laptops
Samsung 840 non pro oem slow sequential write on lenovo laptops
Hi,
I have a problem with my ssd, it's a lenovo's fru ssd, samsung 840 non pro oem MZ7TD128HAFV-000L1
I've checked using Samsung Magician and it showed that the sequential write is below 100 MB/s
http://i15.photobucket.com/albums/a364/ ... wxgjdc.jpg
http://i15.photobucket.com/albums/a364/ ... tpys5v.jpg
I've tried to update the firmware using firmware update utility from lenovo's site, but it said "no update available"
current firmware on the drive is DXT04L0Q, my samsung 840 non pro retail version has DXT07something firmware
the latest firmware provided from samsung is DXT09something, right? but it's for the retail version, not for oem version
I know that samsung does not support oem ssds, but does anyone tried to update the firmware using the retail version?
big chance that the retail firmware can "brick" the ssd .. but I haven't tried
Thanks for your answers.

Re: Samsung 840 non pro oem slow sequential write on lenovo laptops
Which thinkpad series do you have? There seems to be a problem on many SSD's with the writing side of things.

Re: Samsung 840 non pro oem slow sequential write on lenovo laptops
tested on my W510, T61 and T430s from a friend of mine ...
compared to my retail version of 840 non pro, the writing speed on this oem drive is waaaaaaaaaaayyy to low ...
even 470 oem on my W510 is far better than that

Do you have trim calibrated properly? Run a benchmark on the below site and you should have more than 1,400 other 840 EVO's to compare your SSD performance wise.aoitenshi wrote:tested on my W510, T61 and T430s from a friend of mine ...

Re: Samsung 840 non pro oem slow sequential write on lenovo laptops
Samsung have released second version of 840 evo software to address the stale data read performance.
Cheers, thinkpadcollection.

TRIM was not a problem, I've checked itHans Gruber wrote: Do you have trim calibrated properly? Run a benchmark on the below site and you should have more than 1,400 other 840 EVO's to compare your SSD performance wise.

It is fast when load things up, but darn too slow when saving a large file
I think it was for retail version of the drive, what I have is the oem version, the one that shipped with lenovo laptopsthinkpadcollection wrote:Samsung have released second version of 840 evo software to address the stale data read performance.
Cheers, thinkpadcollection.
and my problem is the poor writing speed, not the reading speed
my samsung 470 oem 128GB is running a lot better than this 840 oem 128gb
I already purchased another 840 oem drive with 256GB capacity ..
This drive has newer firmware than my 840 oem drive
I'll report back when I have the unit on my hand

Re: Samsung 840 non pro oem slow sequential write on lenovo laptops
I feel your pain and frustration. I have been suffering from burnout acquiring so many Thinkpads in such a short period of time. Today a Toshiba 128GB mSata SSD drive arrives in the mail. The mSata adapter arrived yesterday. I have to transfer 1 SSD to another T410s and juggle ram in each machine. What is worse? I stripped down an old Toshiba for the 320gb HDD and googled the model number wondering how old it is. They still sell the Western Digital Scorpion Blue drive on newegg.com that I just pulled out of a Toshiba with a Core Duo Intel CPU which is one generation before the Core2Duo. I upgraded the HDD maybe 5 years ago or less. I will probably use the HDD drives from old laptops for the T410 models.
Can you upgrade the firmware on your Samsung EVO 840 without wiping out all your data on the drive?

I updated my firmware yesterday and the data is still there.Hans Gruber wrote:Can you upgrade the firmware on your Samsung EVO 840 without wiping out all your data on the drive?
Note: Their ISO (Samsung_Performance_Restoration.iso) failed to book.
First I tried using 'dd' then UNetBootin.
UNetbootin booted the firmware but the initram file path was wrong.
From 'boot:' I edited the path to vmlinux (or a similar file), removing ISOLINUX/ and it booted.
