SSD-specificaties

Casus (okt. 2020): Ik heb een nieuwe laptop en daar wil ik een SSD voor kopen. Maar wat zijn de specs van de interface op deze laptop?

Let op: Verifiëer dat het device waarvan je de gegevens boven water probeert te toveren, wél je harde schijf/SSD is, en niet bv. je DVD-speler! Dit overkwam mij op een computer waarop de SSD niet bereikbaar was.

Conclusies =

Dit geldt voor al m'n laptops en al m'n SSD's (tot en met okt. 2020):

• Form factor: Altijd 2,5"
• Interface: SATA 600 = SATAv3
• Connector: SATA

Alle mogelijkheden

Het blijkt om drie min-of-meer losse vraagstukken te gaan [2]:

Form factor

Mogelijkheden:

• 2,5"
• M.2 42mm
• M.2 80mm
• M.2 110mm
• Merkspecifiek
• mSAA

Conclusies:

• M.2 is bedoeld voor ultrabooks en tablets. Het betreffende hele kleine module. Niet de "doosjes" die ik in m'n laptops heb
• Volgens mij heb ik altijd 2,5".

Interface

• PCI Express 3.0 x4
• PCI Express 3.1 x4
• PCI Express 4.0 x4
• PCI Express 3.0 x16
• SAS 3.0
• SATA-600

SATA-600 is hetzelfde als SATA v3. Die standaard stamt uit 2008, dus al m'n SSD's en laptops gebruiken deze standaard.

Connector

• M.2
• mSATA
• PCI-e-kaart
• SAS
• SATA
• SATA (M.2)

Dit is connector die ik heb op al m'n SSD's. Dus SATA [1]

Specs achterhalen

Enkele uitprobeersels ahv. m'n laptop Dell2016:

lsbsk en lsbk /dev/sda leveren beide weinig bruikbaars op:
