Samsung 840 EVO Standalone ISO Updater Now Available

For those of you following the Samsung 840 EVO saga, last week we saw the release of Magician 4.6. Samsung was initially throttling downloads and firmware update rates, but those limits appear to have been lifted as of this morning. Another thing we noticed this morning was the inclusion of the standalone ISO updater for those who are otherwise unable to run the Magician software (i.e. Mac users):

For those on laptops or other devices with no optical drive, I've confirmed the ISO can be used via USB if placed there with a tool such as Rufus.

Note to Linux users:

There was an early report of complications from a user who was running a full disk fstrim during boot, where that operation was causing errors (corrected once that operation was disabled). It should be noted that full disk TRIM operations are redundant so long as the OS is issuing TRIM on-the-fly during regular file moves / deletions. This may be an issue with queued TRIM handling of the new 840 EVO firmware. If not reproduced / corrected by Samsung, the Linux devs may be able to add this firmware revision to the queued TRIM blacklist to possibly fix the problem on their end.

Note to mSATA 840 EVO users:

It appears the update does not currently apply to these. I've asked Samsung about this.

Samsung Magician 4.6 and 840 EVO Firmware Released - Downloads Throttled

For those who watched last night's podcast live, I predicted that Samsung would be posting their 840 EVO Firmware and new Magician 4.6 software 'soon'. Turns out that 'soon' was actually this morning, but there's a catch - Samsung decided to limit the daily downloads:

If you went to the Samsung SSD Download Page and got the above error, don't fret, there are a few mirrors out there:

I downloaded from these three sources and at the time of this posting can confirm all three are identical to the Magician 4.6 download available from Samsung.

Once installed, you *should* be able to use Magician to update the firmware on your 840 EVO and (hopefully) see its performance come back to where it should be. There have been some reports of users unable to update, but that appears to be Samsung's servers being hammered and Magician's default / timeout is to report that you are on the latest firmware. Restarting Magician may force it to re-check and get the update.

Linux and Mac users are not yet able to update as the ISO updater has not been released for the new firmware. Those capable can update their Linux or Mac 840 EVOs connected as a secondary drive under Windows with Magician 4.6 installed. Also, if you're running Linux and happen use fstrim during boot, read this post prior to updating.

More on Samsung's new cached SSD wizardry

Along with Al's review of the new EVO line you can get a second opinion from The Tech Report about the performance of the new SSD with a fast cache.  The majority of the storage is 19nm TLC NAND but there is an SLC cache sitting between the controller and that long term TLC storage to help with the overall responsiveness of the drive, aka TurboWrite. In the 120 and 250GB models that cache is 3GB while in the larger models you get a 6GB cache.  In their real world testing the new EVO drive is incredible at large file copying though Sandforce drives can beat it in small file copy speeds, likely thanks to the compressed write trickery that controller family is so good at.  Check out the review here and keep your fingers crossed that MSRP is the acual price these drives sell at.

Introduction and Specifications

Introduction:

Last week, Samsung flew a select group of press out to Seoul, Korea. The event was the 2013 Samsung Global SSD Summit. Here we saw the launch of a new consumer SSD, the 840 EVO:
