Sas drives or SSD ?

[MassiveJim]

My business server is a Dell R720.
Main storage is currently handled with 4 x 300GB SAS drives in RAID 10.
Running out of space, so considering upgrading the drives.

Do I buy 4 x 600GB 15k SAS Drives at about £80/90 each or go for 2 x Samsung PM883 960GB in Raid1 at a cost of about £350 total ?

The array is used for general network storage on a 2 person network, there are shared excel files that are use regularly.

WWYD ?

I'd always buy what fits your budget. Simple as that.

If you can afford ssd, then go down that route. I doubt there's much difference in price at this point.

Cost is about the same but configuration will be different
4 x 600GB in RAID 10
or
2 x 960GB SSD in RAID 1

I wouldn't worry much about RAID1 SSDs for his use case provided he is keeping backups.

He could get 4 1TB consumer SSDs and run RAID10 for the same money as the PM883s.

Backups are regular and working. 99.9% of data is non critical anyway.


In fact I have just had a look at what is actually on the drive, and a better way of doing this would be to move some none-essential data on to a cheaper storage medium
I have around 120Gb of machine images
and around 150Gb of various MS and Apple OS image files

None of these need to be on expensive storage.
I already have everything backed up to a 12TB Ironwolf drive, perhaps I should get another large capacity NAS drive and keep that data on there instead, finanically at least it makes more sense.
currently have 2 x PM883 RAID1 servering as the main OS drive for Hyper-V and storage of VMs
4 x 300GB SAS as main network shared storage
1 x WD 8TB Gold as main backup drive for my home NAS (Backups up over the internet)
1 x 12TB Ironwolf, serving as main backup for all data on network, is VEAMM repository drive as well.

The issue is that every bay is full at present so adding additional storage might not be possible.
Is there way of adding internal storage to the R720 chassis ?
