Thinkpads Forum

Now, if one buys T400 Thinkpad, Lenovo allows you a couple of options in terms of SSD drive:

64 GB Solid State Drive, Serial ATA [add $212.50]
Intel 80GB High-Performance Solid State Drive [add $340.00]
128 GB Solid State Drive, Serial ATA [add $382.50]

As I know nothing about Solid State Drive, which one of the above is a SLC SSD which is superior? Or maybe none of them is?

Thanks

Most likely, none of these options is slc ssd, they are cheaper mlc ssd where the 80 gb is an intel mlc ssd which has superior reading and comparable writing speed compared to a slc ssd. You can not go so wrong with the intel 80 gb ssd. However, I'd get the cheapest hdd and upgrade the thinkpad to a slc ssd myself. Upgrading the hdd is fairly simple: First create the lenovo restore cds / dvds from Windows > Thinkvantage, then change hdds and replay the created discs on the new slc ssd.There are lots of people who do not mind using a mlc ssd. However I bought a x301 with mlc ssd and it was too slow for me compared to my some years old slc ssd.

The best SSD option is by far the Intel x25-m 80GB - but as ssd_thinkpad said, just get the base hard drive and replace it yourself.
