question

Can I remove Raid 0 hard drives from this array without losing data? And keep it as back up then reuse later whenever I want?
Asked by: Oudom
The only way to remove a RAID 0 array while keeping the data intact is to remove both of the drives together, and then when you want to access the data again, both drives would need to be placed back inside together. This however is not recommended.

question

I have 2x10TB RAID 0 on my WD book and its full now. I would like to replace another 2x10TB to continue using. Is it possible? if Yes. Will my first 2x10TB RAID drive lose any data once I plug back into enclosure?
Asked by: Oudom
If you remove both drives at the same time and put them back in at the same time, no data will be lost when you put them back inside the enclosure, however we do not recommend using an array this way.

question

Can I replace these 2 red drive to 10 TB gold ? will it inrease my read/write speed ?
Asked by: Oudom R.
A hard drive's performance is best measured by data throughput and usually measured in gigabytes (or gigabits) per second. Data throughput is directly related to how densely data is packed on the hard drive (areal density) and the speed at which the platters rotate (RPM). Comparing the performance and read/write speeds between two hard disk drives that have identical areal density specifications (BPI or bits per inch, and TPI, or tracks per inch), a 7200 RPM drive will deliver data about 33% faster than the 5400 RPM drive.
