محركات الأقراص الصلبة مقاس 3.5 بوصة

They hold bulk data: backups, file shares, archives, virtual machine templates and surveillance footage. Because they spin at 7.2K RPM they are slower than 2.5-inch 10K drives or SSDs, but they give far more capacity per drive and per riyal, which is what those workloads need.

Yes. Server makers use large form factor, or LFF, for 3.5-inch bays and small form factor, or SFF, for 2.5-inch bays. An LFF server usually holds fewer drives than an SFF server of the same height, but each drive can be much larger.

With multi-terabyte drives, RAID 6 is the safer choice. It keeps working if two drives fail, which matters because a rebuild on a large drive takes many hours and puts extra load on the remaining disks. RAID 10 is an alternative when write speed matters more than usable capacity.

Generally yes, if the NAS supports the interface. Most NAS units take SATA drives, and some rack models also accept SAS. Check the NAS maker's compatibility list and the drive tray, or send us the NAS model and we will advise.

You can, but each drive only contributes the capacity of the smallest member of the array, so the extra space on larger drives sits unused. Mixing also makes spares harder to manage. Where possible, build each array from drives of the same capacity, interface, speed and sector format.

Yes. Send the capacity, interface and quantity you need, together with the server or NAS model, by WhatsApp on +974 5521 2108 or through the contact page. The team will check what can be sourced, confirm the drive suits your system and send a quotation.
