Here is mine result.

Usually the box or ssd label have firmware version info. You can also use crystal diskinfo to get the firmware version.

You can download new firmware from goplextor.com. The update procedure is simple, and is normally non-destructive. For safety's sake, just do a data backup first. Create a usb bootable with the iso via rufus/pendrivelinux tool and use it to boot and apply the update.

The need to update the firmware depends on issues on the current firmware. it's optional if your drive works well.

Hi,

i would like to get some opinion for SSD selection.
Between these 3 models, which one would you recommend?

1. Lite-on S900 128GB (read: 530 MB/s; write 290 MB/s)
2. Kingston SSDNOW V300 120GB (read: 450 MB/s; write: 450 MB/s)
3. ADATA Premier Pro SP900 128GB (read: 550 MB/s; write: 530 MB/s)

Lite-on is the newest (2015) compare to the other 2. Adata SP900 having good read and write to but quite old model (2013) i think.

imo basically they are the same, however i never tried the windows executable version before (i have older models, and they were all in iso formats). for firmware updates, i still think it's safer to use bootable usb stick instead of windows executable.

edit: one more thing, although it has stated that they are non-destructive, it's a good practice to back your full data up first. it maybe seem paranoid, and although i haven't had any bad experience with brands like plextor, crucial and samsung in this regard, it's better safe than sorry.

get the plextool v1.1.7 for fw update to v1.08 (current latest)
