My guess for the LBA size is 512bytes, but I am not sure? Some experiments I ran by writing set amount of data to the SSD and measuring this attribute's value indicates it is 512bytes. Other SSDs, may use other SMART attributes to convey total data written to disk.Įspecially, for Samsung 840 Pro (and may be even for other Samsung SSDs?) SMART Attribute Id 241 - Total LBAs Written conveys this information. Here, the best answer shows the SMART Attribute Id 225 stands for the total write I/O in size of 32MiBs performed to the SSD until now.

Is LBA size one of them?, I don't know.Īnother excellent information source is How to determine number of write cycles or expected life for SSD under Linux? - Server Fault. Some specific parameters may differ between different SSDs. These attributes are specific to Intel SSDs, but nevertheless gives an idea, what kind of information SMART attributes convey. To understand what each SMART attribute means check this Intel S.M.A.R.T Attributes. For more information about these class of tools check Smartmontools - Community Ubuntu Documentation. I found the gsmartcontrol (gui version of smartctrl) especially helpful. I am going to add more info here which I came across after digging the internet. I looked up the smartctl command from smartmontools suggested by Selivanov. I know the SSDLife tool on Windows does this, but I am specifically looking to do this on Linux. The output should look something like this: SSD Intel 320S :-īut I haven't found one. I've searched the internet to find a tool/utility which can tell me the total writes performed to an SSD (or a normal disk).
