Compatible SSD

Would the SanDisk SDSSDXPS-240G-G25 be compatible with the kronos?

More than likely it would.

Great, thanks a lot, just ordered one

Hi metallo, how did u go with the upgrade?
I assume you are replacing original ssd, not adding second one?

I am about to replace mine. I read past posts, and most were replacing with ~120gb. I think I saw posts about problems with 256gb. That's from 2013.
120 would do I guess, but the price of 256 dropped since then ...

Anyone with 240-256 gb ssd in their Kronos?

My 2 cents.
Replacing the original drive is a very bad idea. Adding a second drive is by far the best way to go.

Why is replacing the original drive a bad idea? I think I read a post that said it was very difficult for some reason, but I can't remember why. I'd like to use the Intel 530 that was mentioned in a different thread recently. Also that the Intel only uses 0.2W which means you don't need a fan. I was thinking of using a newer silent fan anyway, but maybe something with less airflow.

I was thinking of a clean install with OS 3. I think someone mentioned in another thread a while ago that there are SSDs with a faster transfer rate than the original, and I'm hoping that the Intel is one of them. I mainly want more storage, but if I'm going to open it up, I'd like to upgrade it as much as possible.

Thanks for all your posts, and for running the website Sharp. It has been very helpful. Cheers

Thank you Sharp, I'd be interested too to know what major concerns are.

page three scroll down for a model that has been used is cooler running and fast. http://www.korgforums.com/forum/phpbb2/ ... c&start=30

Hello.

I think it's a bad idea because there's only two ways you can do it and both ways require a very clear understanding of the work your about to bring on yourself. It's by no means a simple process of replacing the factory hard disk.

Method 1, the worst of all.
So you remove the factory drive and install your new one. You now need a USB-DVD Drive and a copy of the KORG OS DVD's (these disks must also be v2.0 or higher) in order to boot your KRONOS and do a “FULL” OS install of the OS to your new larger SSD. You now have to Calibrate your KRONOS as the OS install does not contain that very important data. Calibration is a procedure meant for a KORG engineer, not an end user. Which is why you won't find this in any manual and so you will find out what the procedure is and how you preform the calibration from KORG or someone on the forum who knows how it's done. After you manage to do that you still have to go to KORG's website and then upgrade to the latest version of the OS using a Memory Stick.

Method 2. Cloning.
You remove the factory drive, connect it to a PC/MAC and use cloning software to clone the factory SSD to the new drive, making sure it also clones the partition where the calibration data is contained.

Where if you simply add a second SSD you don't have to do anything other than make sure it's connected to SATA port 1 and the factory drive is connected to SATA port 0. Boot up as normal and format your new SSD.

Regards
Sharp.

This is the first time I see the need to "calibrate" mentioned, so thank you for sharing.
Technically I knew enough to go through method 1 or 2, but not knowing how to calibrate leaves me with option 2, or second drive. I want to keep it simple, this keyboard is for my "music", not "electronics" hobby

.

Out of curiosity, calibration of what is required? Aftertouch, controls, screen?
If you'd like to share.

I'm not sure, but I can imagine lots of things:
- key responsivitity (per key)
- aftertouch (per key)
- pitchbend wheel
- vector joystick
- display
- fan settings
- slider sensor settings (per slider)
- knob sensor settings (per knob)

Calibration data are fixed for every keybed type of Kronos and included in a Ext partition of factory SSD that will not be
deleted in full format procedure of official DVD installation (which requires re-authorization).
My tip in that post for replacing factory SSD is only for advanced user who know what they're doing and primary based
in cloning SSD method , that's why I said there "for anyone that intends to replace factory SSD".

Thank you Antony.
by the way, in your previously quoted post you mention no need for fan if low power ssd is used. i'll be using quieter fan anyway, already ordered, but what you wrote is very tempting. how do we know that ssd is the only major source of heat inside Kronos? again, i'm curious if you skipped fan in any installation you did.

sorry, one more question. is SATA 3 ssd ok for Kronos? I know SATA 3 ssd should be backward compatible with SATA 2 interface of Kronos, but I saw many posts talking about failures with SATA 3. Not sure if it was because of particular ssd model that might have been incompatible.
(it's not easy to find SATA 2 disks anymore ..)

SSD fan was disconnected and removed from the first week I bought Kronos ! I can't tolerate fan noises as I develop sounds on it !
That first Toshiba SSD was too slow and power consuming that's why engineers installed a fan !
Just imagine how weird it was , when already Kronos has a fan-less SM Power Supply , to use a fan for what ? SSD !!!
So before 2 years , I replaced factory SSD (via cloning) with a Sata3 Samsung of 120 GB at 0.7 Watts and it was always
in environment temperature !
My latest and single SSD is Intel 530 series 240 Gb sata 3 at 0.2 Watts , Kronos is always powered on (development stuff)
my boot time with full 2 Gb Streaming Ram is less than 2.30 min and the only component that has ever failed is power supply !
Also all SSD sata 3 I had ever used worked all fine , so it's the last thing to worry but when cloning an SSD , you
also copy the boot sector which means that there no incompatible SSDs in this method , I've even booted Kronos from
an old IDE HD and seem feasible also from a fast USB Stick !

I know that all these seem to be very tempting , but cloning a Linux 5 partitions SSD especially in different SSD size
is a very difficult job to be achieved even from an expert technician !

Thank you for information and sharing your experience Antony. Very helpful.
And as you say, very tempting!
