Firmware upgrade frenzy during the weekend: Nokia N9, Synology DS411Slim, Netgear FVS336Gv2

The Nokia N9 looked like if it was running on windows 7: over 280MB of updates. Twice.
Hopefully I’m on the most recent version now and, yes, email synch seems to be faster that when unboxed as promised by the update description.

The upgrade of the DS411Slim doesn’t look like has fixed my issues with slow transfer rate from the encrypted volume.
Even worse: I’ve had the time to test with the regular volumes and it looks like they are slow too.
I’ll post more detail on my findings once I’m done with the backup od the encrypted volume and can remove it from the NAS.

The FVS336G was working stable (with the exception of a relevant slowness in managing the WAN interface up-down-up transitions) before the upgrade and seems stable now too.
I decided to give a try at the updated FW ( : the list of fixed problems in this release was impressing and I was on an 18 months old version (3.0.7-24)

Synology DS411Slim and encryption: DSM 4.0 not helping performance for me

I’ve written recently about the poor performance writing to and reading from an encrypted volume on my Synology DS411Slim.
In an attempt to improve the bad numbers I’ve decided to take the risk of updating from a firmware that I knew was working for me (DSM 3.2) to a more recent one (4.0)

The interface looks sleeker than the previous one, but unfortunately there it is no improvement at all in writing to the encrypted volume.

DSM 4.1 is available too, I’ll likely give a try at it too as there are no major reports of problems.

Synology DS411Slim and encryption: major negative impact also in reading.

A few days ago I created an encrypted volume on my DS411Slim and reported a major degradation in writing speed.
I hoped that reading was maintained in the original ballpark, but this is not the case.
12.5MB/s is all I can get and is very bad in comparison with the former 70+ MB/s

Since my first post I did some research and, according to Synology’s own tests, I should get about twice the current speed.

I’ll give a try at a more recent version of DSM (I’m on the stock 3.2) to see if it provides better performance.
I’m usually a bit reluctant to update the firmware of working devices, but the opportunity of getting better performance on the 50GB backups is pushing me in this direction.

Synology DS411Slim and encryption: an unpleasant surprise

Some time ago I built an encrypted volume on my small nas from Synology and today I did the first real test.
I’m backing up an entire volume with Disk2VHD, a nice free utility from Microsoft’s Sysinternals tools to make online volume snapshots.
I did this in the past several times from the same machine on a regular non-encrypted volume on the same nas obtaining about 37 to 40 MB/s of sustained writing speed.

Given the hardware encryption engine included the nas I was expecting a similar performance with the encrypted volume but this is not the case.
The speed is down to 7MB/S, a sharp 80% loss.
I’m running DSM 3.2
I wonder if this is common/expected or not.
The backup will have to be again a nightly activity until I find a way to get back the high-speed when using the encryption 😦

Update: I’ve had the opportunity to test large reads too and it’s not looking good


Packard Bell iMedia I6657IT: you get what you pay for. And nothing more.

I helped a friend to pickup a new pc for his video editing hobby.
He was on a budget yet needed some muscle so we picked up this system (4-cores i5 and 8GB of RAM) even if we weren’t able to find online a review of the system.

After just a couple of days the box arrived from Amazon and we unboxed and installed the system last Friday.

On the plus side: the system has a nice HW specification for a good price, is compact, mechanically robust and extremely silent.

On the minus side: it ONLY has what is implied by the advertised HW.
We opened the system to add the HDD from the older PC and found out that there is no space to put it.
But this is a piece of the expansion problem: only the SATA headers for the included HDD and DVD are soldered on the motherboard.
The same cost-saving approach is used for the other interfaces that are common on DIY core i5 system.

There it is one PCIe 1x slot available that could be used to add SATA and or USB3 ports.
We should be able to go for an external high speed enclosure to expand the system in the future.
