[3dem] Data storage system

[Ludtke, Steven J.]

If you want something requiring minimal IT support but with good performance, I have purchased several of these (we use them mostly with individual workstations, then have traditional rack-mounted RAIDs for the larger archives):

Synology 12 bay NAS DiskStation DS2419+
https://urldefense.com/v3/__https://www.amazon.com/Synology-Bay-DiskStation-DS2419-Diskless/dp/B07NF987TP/ref=sr_1_3__;!!Mih3wA!SIeQ8SR_6IDaerUO5wDhBalegHnwL4VNvWmoh3CWrS25yS3Dwva5vqo63Y5zyRMFbw$ 

This costs ~$1500
add a 10gb network card to it (~$150) it can easily do ~950 MB/s read speed, and about 600 MB/s write speed (if you have a 10gb network to plug it into).
load it with 16 TB drives (~$4500), you get ~150 TB of usable space (configured as a RAID 6). It is all web driven and user-friendly.
it is also usable in an office environment (fairly quiet, no jet-speed fans).

so ~150 TB for $6000
It is also possible to supplement it with a second 12 bay JBOD box to double the capacity.

Don't get me wrong, this is not an optimal solution for >500 TB, but it is pretty decent for a good sized CryoEM lab.

Hello,

I am requesting suggestions and cost estimates about off the shelf data storage systems to store raw cryo-EM movies and processed data for our lab. Our initial target is 150-200 TB with options to expand it in future.
We don't have much local IT support for Linux based systems, that's why I am asking for an off-the shelf system which should be easier to install and manage.

Thank you
best regards

Krishan Pandey
