Guts of a 16GB Transcend SLC SSD

5 posts in this topic

I scored this industrial grade SSD on eBay and just had to see what's inside.

See TranscendSLC_TS16GSSD25S-S.pdf for high-res photos of the internals.

It would appear that 16 Samsung 1 gig NAND chips are used...with zero over-provisioning. I would presume this is because SLC does just find without a bin of extra bytes to draw from, as compared to MLC. The controller is a jMicron JMF602.

Yes it does have overprovisioning

Based on LBA count of 31,277,056 sectors the drive has 16,013,852,672 bytes of user accessable storage.

16GB of NAND is 17,179,869,184 bytes. That means that the drive has 1,166,016,512 bytes of overprovisoning, (or about 6.7%)

This is plenty for a small SLC based SSD.

However, the JMF602 controller is quite awful, I wouldn't have bothered buying it.

I agree, the controller is crap. But for my particular purpose, it is still much better than a platter drive.

Good to know about the overprovisioning bit too.

EDIT: And I only paid $22 :-)

$22 for a JMicron JMF602 is about $21 too much. ;)

LOL you are funny. But the drive is working perfectly as the OS drive in my NAS :-)
