NAS upgrade / RAM

[Enquiries]

Hello,
I came across your YouTube channel, and it has been a great source of knowledge -thank you for sharing your time and knowledge on there.

You mentioned in your videos to contact you with regards to getting some advice...

I am looking to upgrade my DS1513+ to a DS1522+ (or a DS1621+).
As well as hosting my source files I want to be able to run docker images on it (about 10 initially).
The DS1522+ come with 8gb memory on it and I was thinking of expanding that to 16gb by getting another RAM module -as well as adding some NVMe SSD drives for the Cache.

Some questions...
1. Which is the best third-party RAM that works with the DS1522+?
(I thought maybe the Kingston ECC 8gb -but it links to Crucial RAM instead)

2. Can I mix the memory -or should I get 2 x 8gb that are from the same brand ?

3. I was thinking of getting a couple of WD Red SN700 1tb (raid1) for the cache -would you recommend them -as well as the size?

Thanks in advance for your help.
Pete

Yes, Crucial memory seems to be the most reliable. With Docker you may need to stay with ECC type of memory for reliability.

When choosing NVMe for caching you need to look at reliability ratings such as DWPD/MTBF. Here are a few on the list

Caching means a lot of read and write operations, unlike regular storage situation.
You would need to look at models with 0.5DWPD and above

970 pro – 0.66DWPD

Synology SNV3400 – 0.68DWPD

Seagate FireCuda 510 – 0.7 DWPD
Seagate IronWolf 525 – 0.7 DWPD
Seagate Firecuda 530 – 0.7 DWPD
Seagate PS5 Game drive – 0.7 DWPD

Seagate FireCuda 520 -0.9 DWPD
WD Red SN700 – 1.0DWPD

I hope this helps.
