Enterprise hard disks (these tend to have rotational vibration safeguard, five year warranties and cost at least twice as much as consumer disks) from the HCL. What model is included may vary depending on availability to NetGear at the time of production.
My vendor quoted me RNDP4 Diskless with 3 Qty of ST2000NM011 (2TB, 64MB, 7200rpm, 6GB/s drive). Will this hard disk be supported by the proposed RNDP4000-100EUS?. I could not find this type of HDD in the HCL.
Also, If I buy 3 Hard disks of the above model, can I configure RAID5 on that?
In the HCL I found Hard disks with different data rates. (some 3Gb/s, some 6Gb/s). Will this affect the overall throughput?. ie., I may get less throughput with 3Gb/s HDD and more throughput with 6Gb/s HDD?
The throughput into the network will be limited by the CPU and NIC. Even on a gigabit network you won't get more than 1Gb/s so even the old 1.5Gb/s SATA1 drives would saturate it. They make a difference if you had an Enterprise 10gigabit network or if you have the drive internal to a PC with disk intensive applications.
If this is for a home network, you might want to consider the lower cost consumer grade drives versus the enterprise grade drives. While the consumer grade drives are more prone to failure than the enterprise, it does not mean the enterprise drives will not fail (all do eventually) or that the consumer grade drives will fail prematurely. Some will and some will run for years. They are all electro mechanical devices and can either fail mechanically, or electronically and then you have the potential problems with the disk coating. But, then this is why we have Raid - to protect against a single drive failure. Do not however, think that a Raid device does not need to be backed up, they do.
Most of us who run consumer grade drives buy 5 if we are going to fully populate a 4 bay NAS. That way we always have a spare on hand. Plus, you can buy 5 consumer grade drives for far less than 3 enterprise class drives. If you only install 3, then you have 2 left, 1 for expansion, 1 for a spare.
This is for business use. Actually we are now using the space in the file server(800GB), which uses SCSI and newtwork bandwidth is 1Gb/s. There are only 30 users, a few of them (like 10 - 15 users) are using pictures / big presentations and all of them will be saved on the network drive. Currently the space on the server is almost full and I want to go for an additional storage.
IF 3TB is enough for me, is it good to go for a RNRX4410-100EUS model with 4 x 1TB HDD and RAID5?. I will use a low cost NAS for a backup for this one. your advice will be highly helpful.
I ran my first NVX for almost a year with 4x1TB drives. I was reaching about 60% of capacity, so a month ago I replaced two of the 1TB drives with 3TB drives and boosted my net redundant capacity after overhead from 2.7TB to 4.5TB and am now about 38% full (videos really eat the disk space). Since you are currently using about 800GB, 2.7TB (net) should last you a good while and with the X-Raid2 function, you can upgrade in stages.
Last fall, when they were discounting the NVX units, I purchased a second (Business Edition this time as it was $40 more than the Pioneer and had a 5 year warranty). The Pioneer that I had first is now the backup unit. On advantage of having a second matching unit, is that if something happens to the primary, you can shut it down, have your clients shutdown and then rename the backup to the same name as the primary, bring the clients back on and continue in operation while the work on the former primary that is causing problems. You might not be able to do that with a "cheap NAS".
