Thank you to all respondents in our Data Storage Survey which provided some interesting results! 

We will be announcing the winner shortly, but please see below for the answers we were looking for...

1. Which family of Flash storage products feature market-leading InfoSight predictive analytics?

Please tick one box.

a. HPE Nimble
b. IBM Storwize
c. Oracle ZFS
d.None of above

Answer: HPE Nimble

2. Which type of recording media is the most cost effective for storing large data volumes for periods in excess of 10 years?

Please tick one.

a. HDD
b. SDD
c. LTO Tape
d. Optical Disc

Answer: LTO

LTO Ultrium tape media continues to be the most cost-effective and reliable format for long-term storage of large data volumes. Latest generation LTO-8 tape media enables 30TB capacity per tape, for storage of upwards of 30 years. Some optical discs offer 100+ years storage, but capacity is very limited compared with tape, and therefore costly per GB

3. Which of the following would provide the largest native storage capacity?

Please tick one.

a. 32 slot LTO8 tape library
b. 8-Bay NAS HDD
c. 16-Bay NAS SSD
d. 10 slot Optical Disc Library

Answer: 32 slot LTO8 tape library

A 32 slot tape library such as the HPE StoreEver MSL3040 provides up 960TB compressed storage capacity in just 3U of rackspace.

4. Which storage format is least susceptible to Ransomware attacks?

Please tick one.

a. Flash
b. Tape
c. Disk

Answer: Tape

Tape media is generally offline or stored offsite, so near immune to Ransomware attacks, hacking, malware and viruses.

5. Which RAID configuration is considered the 'safest' but also the 'slowest' when backing up data?

Please tick one.

b. RAID 5
c. RAID 1
d. RAID 6

Answer: RAID 1

RAID 1 is an exact copy of data written to 2 sets of disks at the same time, so is a slow but reliable method of writing multiple data copies. RAID 6 is generally considered the best all-round RAID setting for speed versus reliability.
