Dell r720 SAS drive replacement

Hi all,

We have a r720 with embedded Perc 710 mini adapter. We have 8 Dell Sas HDD 600 Gb 10k 2.5" 6 gbps disks.

We have two types AL13SEB600 and ST600MM0006 on array. We have used all of our spare new disks and can not find any same models to buy. All disks I can find are even 12 gbps or 15 K.

Can you please recommend an actual Dell disk model that I can buy and replace at any disk failure?

Thanks,

Gonen
