<div dir="ltr">Hi all.<div><div><br></div><div>Our lab is also currently making similar considerations for a moderately large server.

Hi Krishan,<br>
<br>
Our 60-drive 760 TB FreeNAS has been running flawless since more than 1 year. One failed drive was easily hot swapped. If you want capacity, this does not cost more per TB than inferior hardware, yet you get good redundancy and performance.<br>

Subject: [3dem] Data storage system<br>
<br>
Hello,<br>
<br>
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.<br>
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.<br>
<br>
Thank you<br>
best regards<br>
<br>
Krishan Pandey<br>
