What is the largest capacity single hard drive you can find for sale on the internet (newegg.com or amazon.com are good options)? What is the capacity? How much does it cost? The largest capacity single hard drive I could find had a capacity of 20TB (Terabytes). There were a couple. One was called “Seagate Exos X20 ST20000NM007D” it says it costs $699.99 but is currently on sale for $279.99. There was also a hard drive with 22TB capacity but it was cheaper than the 20TB one so I wasn’t sure if it was what I looking for, called “WD Red Pro WD221KFGX 22TB 7200 RPM 512MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive” What is the largest capacity single SSD you can find for sale on the internet(newegg.com or amazon.com are good options)? What is the capacity? How much does it cost? The largest capacity single SSD I could find was 8TB. One was called “Corsair MP600 PRO NH M.2 2280 8TB PCI-Express 4.0 x4 3D TLC CSSD-F8000GBMP600PNH” and cost $819.99. Find and compare 2 hard drives of the same capacity from the website newegg.com that have a significant price difference. What may be the reason for this, include one specification to back up your thoughts. On Amazon I found “Seagate ST8000DM008 BarraCuda 8TB Internal Hard Drive HDD” originally for $179.99 but on sale for $109.99. I also found “Western Digital 8TB WD Blue PC Internal Hard Drive HDD” for $129.99. I’m going to base this on the original prices. The Western Digital Hard drive has 5640 RPM vs Seagate with 7200 RPM. The Seagate one is also designed for NAS. _Compare an SSD to a Hard Drive. Do a feature-to-feature comparison for at least 2 features other than size. _ I chose the “Seagate Exos X20 ST20000NM007D” for a hard drive and the “SAMSUNG 980 PRO M.2 2280 2TB PCIe Gen 4.0 x4” for a SSD. One difference in features is that the Seagate hard drive uses SATA and the Samsung SSD uses PCIe. These are two different types of bus interface. PCIe is faster reading and writing than the SATA because of more connections. You can actually see the difference in read speed in the specs. The Seagate Hard Drive has a read speed of 285 MB/s and the Samsung SSD has a read speed of 7,000 MB/s. So the SSD is much faster than the hard drive.

Briefly describe the difference between SAN and NAS. Storage Area Network vs. Network-attached storage. SAN and NAS are both storage systems that are network-based. SAN or Storage area network is a high-speed network that uses block storage, it’s made up of hosts, storage devices, and switches. NAS or Network-attached storage is when users can access shared storage through an Ethernet connection. The difference between NAS and SAN is that SAN usually uses Fibre Channel to connect to the network and NAS uses Ethernet connection.
