What size SSD

Post by Wally3218 »

What size SSD is recommended for windows 11 and Blue Iris V5 and should I have them on the same drive
and what size HDD for my stored clips.
Is there a basic setup that I should follow.

My 250GB Windows SSD's are quite small by todays standards. Since I only fill them 50% that appears to be fine, and that is with a portion locked off for the SSD to reduce wear.
I don't store BI5 video on C:/ so have multiple extra drives in all pc's for data. The BI5 pc then has a 1TB SSD for New, Alerts etc (and 200GB locked off for reducing wear), and 18TB of spinning platter storage.
There is no standard build. It depends how many cameras you have and how long you want to store video for. It depends on the resolution of your cameras too.

For the main OS drive, I’d say 250Gb SSD at min. My OS drive has the OS and BI installed onto it.

For recording drives, that is entirely dependant upon what you need, I have a 2Tb and a 6Tb drive installed for clips. I did have an 8Tb installed instead of the 2 but it had issues which turned out to be the SATA cable in the end but haven’t got round to swapping it over.

I guess the main point is to get a pc with a case large enough for a few more drives when you inevitably need them. Small form factor pc's will restrict you. My BI5 pc has three sliding drawer hard drive caddies in the front, as well as the normal internal HD positions. All fan cooled.

I always keep the BI5 video folders away from the Windows drive as BI5 errors can cause drives to overfill, which would crash Windows. Windows is perfectly capable of crashing itself without any help.

Oh, and always leave a bit spare on each storage drive.

Consider SSDs as consumables like you would tyres on a vehicle.

Depending on your application, you may consider something like a 2Tb SSD (or a RAID1 mirror ) as the primary storage drive, then move aged files to a mechanical drive once the SSD fills to 50-70% capacity as others have already mentioned.

A good type of hygiene is to periodically clear most of the SSD and run a TRIM task on it. By default, Windows runs a trim monthly, but the task runs better if the drive is empty of data.

A TRIM can be manually invoked by starting Powershell as administrator:
Right click the Start button > Windows Powershell (admin)

If your SSD is drive letter F, type the following, otherwise replace the letter for your SSD:
Optimize-Volume -DriveLetter F -ReTrim -Verbose

There's little harm in running it more frequently - BI5 fills my 2Tb SSD in approximately 5 days, so I run the TRIM weekly. Doing it too often may cause additional drive wear.

The operating system and pagefile drive, as long as it's no more than about 60% full won't really benefit from increasing the TRIM schedule from the default monthly schedule.

Addendum:
If anyone's interested in what TRIM is, have a read of

Furthermore, TRIM usually doesn't in external USB enclosures. This means your SSD is likely to rapidly slow down and fail early.
