I was plagued with the 'freeze during copy' issue with my ReadyNAS 104, forcing me to physically pull the plug and then wait thorugh a 72 hour resync when it happened with 6.4.0 and 6.4.1. I installed 6.4.2 - T59 on Saturday and ran some tests. I copied a couple TB to my ReadyNAS - a mix of small, medium, and large files, sometimes solo, sometimes at the same time. After about 36 hours of more or less constant copying to the ReadyNAS - no freezes. It does seem like the copies are slower - however, I didn't document my performance beforehand, so that might not be accurate. At least for my specific situation, this might have fixed my freezing issue. Hopefully it doesn't regress with a future update.
After my current copy completes, I need to run some more tests to see if I can adequately stream video from the ReadyNAS to my TV like I could before upgrading to 6.4.0 - which is the primary purpose of this ReadyNAS. That will be an indication of if performance on the unit is similar to before.
I took a shot and updated to 6.4.1 on our 516. With AV disables and no apps running except for Surveillance, performance seems quite good. I'm getting excellent read/write speeds over GigE, and nos connection dropouts.
It seems that normal users are promoted to beta testers. Netgear shows a very unprofesional and clumsy way of releasing their software. Instead of making software more efficient and solving bugs, they introduce another ones. Even worse: 6.4.1 has become unusable. Yes, mine as well. I cannot understand why they released 6.4.1 and why it takes so long to solve it.
I downgraded to 6.4.0 which makes it a bit usable again. However, writing documents to disk remains very slow. I am thinking of restoring to factory hoping that performance is restored as well. It is very sad that Netgear leaves their customers unnotified who are searching and struggling for hours with a faulty product.
Turning off AV seems to have sped things up substantially. This is unfortunate because I like have the additional protection. By the way, Netgear's dreadful tech support earned it the first-ever one-star rating I've given to a product purchased on Amazon. I'm also considering writing to all of Netgear's senior officers.
