Have you opened it up and had a look? – Joe Taylor Jun 15 '11 at 18:44
@Joe I thought about it. I have to disassemble my notebook. Actually I just want to know if it's possible to know it's programmaticaly. And I think that's impossible. – bakytn Jun 15 '11 at 19:23

According to Toshiba that drive is a member of their HG3 family ("HG Series Solid State Drives")


Although they don't seem to specify SLC vs. MLC there, additional reference to the HG3 SSDs can be found here at, which states:

Toshiba's new HG3 MLC SSD drives provide a high level of performance with a maximum sequential read speed of 220MB per second (MBps) and maximum sequential write speed of 180MBps.

So short of a call to Toshiba to confirm, I'd have to go with it being an MLC.

Nope, those are different! Mine is exactly: THNSFC128GBSJ while on the link those are THNSNC series. Strange! But thanks for the link. Something is better than nothing. – bakytn Jun 15 '11 at 18:21
True enough, but the THN drives are their consumer-grade drives, which all use MLC (cheaper, and easily brought into the 100GB+ sizes). Their enterprise drives use SLC (eSLC even); those product codes start with MK (ie: MK1001GRZB). The mild difference in the part number (SFC instead of SNC) is probably due to the channel the drive came from (ie: OEM vs. retail), and/or the country of intended sale, etc. – Ƭᴇcʜιᴇ007 Jun 15 '11 at 18:51
