HOW TO: recognize SSD model

Hello everybody,
i have read on this site, that aspire one have two type of SSD, one more faster than the other
http://www.blogeee.net/codex/index.php?title=Acer_Aspire_One
My question is pretty simple: is it true, and how can i know the model in the one, if possible without open the one?

thanks in advance for your answers.

 

Yes, there are two types of SSDs that are built into the a110.

If you are using linux, you can find out which one you have by entering cat /proc/scsi/scsi into any terminal:

Code:

user@mars:~$ cat /proc/scsi/scsi
Attached devices:
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: P-SSD1800        Rev: Ver2
  Type:   Direct-Access                    ANSI  SCSI revision: 05

Under model it either states P-SSD1800 (Samsung SSD, the fast one) or SSDPAM0008G1EA (Intel SSD, the slow one).

 

Too bad, I have the slow one (bought from Amazon.com a month ago). Does anyone know of a good benchmark so users can post times for the two SSD's?

Thanks for your answer.
We can perhaps make a list of one which have Samsung SSD and the other.
Could all the one's owner write their serial number and the SSD model.
Thanks in advance for all your help

 

Hallo
her is the reed and write times
the farst is
Samsung SSD (P-SSD 1800): 30-35 MB/sec Read / 13 MB/sec Write
and whit the slow its
Intel SSD (SSDPAM0008G1EA): 23 MB/sec Read / 5 MB/sec Write

now i then start to think, is it that whit the samsung ssd. if i put Xp on my ONE will it then be better then what other haw write about it?

 

You can get the raw read speed with hdparm -t /dev/hda (run as root).

 

My linux AAO has an Intel SSD, but the model is different - SSDPAM0008G1 - (note the EA bit n the end is not present), and using hdparm -t /dev/sda yields a read speed of between 36-38 MB/sec...

How can I test the write speed?

 

Same here, SSDPAM0008G1 is the SSD Model, read speeds around 38 MB/s. Maybe I am not so sad about my Intel SSD now

 

You can also check it directly from the BIOS. This comes in handy if you are buying the unit just directly from a shop. Just reboot and press F2 and check your HDD Model. Mine shows P-SSD1800.

 

I also have the SSD without 'EA' at the end, however, whenever i try to run the hdparm command, it tells me command not found, any idea what package it is in?? I may have uninstalled it during the lightening of the system I did by removing lots of packages that i found unnecessary.

thanks

 

It's its own package.

sudo yum install hdparm

I also have the SSDPAMM0008G1 model. According to the datasheet

http://download.intel.com/design/flash/ ... 319955.pdf

Performance
— Sustained Sequential Read Bandwidth:
38 MB/s
— Sustained Sequential Write Bandwidth:
10 MB/s

 

My hdparm results:
/dev/sda:
Timing buffered disk reads: 112 MB in 3.03 seconds = 37.00 MB/sec

But I can't seem to find how to test the write speed... Any suggestions?

 

[root@localhost user]# hdparm -t /dev/hda
/dev/hda: No such file or directory


Any ideas why ??

 

I think there was a typo on the original post. Try changing hda to sda.

 

I thought the SSD used PATA instead of SATA connectors. Shouldn't HDA be correct?
