I'm upgrading to a Sandisk 480G this week. This is far from the fastest unit available but was quite cheap (recycled from one of my PC) and still has 90% life.
Benchmarked it and is giving:

I'll test the original PNY? from KRONOS2 too and post here its speeds.
EDIT: opened, mine is by Buffalo Memory with part number SS306414MGAKG
EDIT2: Finally I had time to change the SSD. I tell you my procedure in case it helps you. It is similar to the one others already written in this thread.
Short version:
1) Clone disk with a laptop booting with Clonezilla live cd to a image file
2) Write image file to new and bigger SSD disk using the same Clonezilla
3) Boot from a Gparted live cd and extend the user partition to the max of your disk
Long version/Considerations:
At first, I was using a windows 10 app I had "Acronis True Image" to do the image file "sector by sector" but I noticed it was writting a 100MB FAT32 partition and messed up the new disk. So after some retries I went with Clonezilla.
Clonezilla procedure is quite straightforward but it could be cumbersoma due to its user interface. I didn't take any pictures though.
You need to select (and mount) the drive to backup and the drive to write the disk image file to.
You need to select working mode: clone a disk to a disk (directly), create a disk image file from a disk (I chose this one), etc...
I had to choose the image disk file because of two reasons. First and wanted to save the image for future use (my Kronos disk was almost factory default). Secondly, I only had a dock station with 1 slot (Inateck brand).
I had to use expert mode in order to it use the linux command "dd". With the other options it failed to create an exact clone image file.
After the image is saved to your local disk (USB external, internal drive or whatever you choose) you simply begin again (or reboot if you prefer) and this time select the "image file to disk" (or something like that) operation. That's all.
At this point, you will have your new bigger SSD exactly as the original. That's it even with only 60GB available. You need to expand the user partition to fill all the space available. I used gparted live cd you can download it and boot from a CD or a USB drive.
This is the original kronos drive seen by gparted:
As you can see, there are already 4 primary partitions: sdd1, sdd2, sdd3 and sdd4.
sdd4 is an extended partition that contains 2 partitions: sdd5 and sdd6
From some systems, like WIN10 they are seen as 5 partitions.
sdd6 is the one that interest us, and ext3 filesystem and labeled /korg/rw (read+write).
The tiny unallocated space is, probably, some leftovers after partitioning the disk.
In the next screenshot you can see the new and bigger disk with a lot of space available and two pending operations.
First, you need to grow the primary partition sdd4 that contains sdd5 and sdd6. Then you expand sdd6 to the max. After applying the changes the disk should show something like this:
Then simply plug the disk to kronos and that's all. No dvd disks should be needed. The space available from "disk" tab in kronos:
My boot times went from 126s to 123s. Not a decent gain but I was looking for space not speed. Anyway, most sata ssd disk are around 500MB/s and are usually limited by the SATA3 interface.
Hope this helps someone.
