|
| The 8M block size used here is certainly excessive.

|
| Something like that:

| But available and more then 2GB ;)

| EDIT: Nice i found something

| I see this listing for Oracle/Sun SLC media.
|
| When you say "really proven," do you mean a lifetime of
| 100k writes, as is normally expected of SLC devices?
|
| p.s. I've bought SwissBit before, and had no problems.

| Does that help?
