Seagate NAS HDD ST4000VN000 4TB 64MB Cache SATA 6.0Gb/s Internal Hard Drive
  • Owned For: 1 month to 1 year

Pros: Huge capacity.

Cons: None so far

Other Thoughts: # A great way to recycle a slighly older desktop into a great, cheap NAS server. (I have lots of Dell Optiplex desktops sitting doing nothing)

# Commands to configure a RAID array on huge 4TB disks (I run CentOS 64bit)
# I used a separate Linux OS disk already installed and
# added 2x4TB disks as separate data store (no OS, not bootable)

# 1) partition each 4TB disk
nas1:root:/home/me> parted /dev/sdb
(parted) mklabel gpt
(parted) mkpart primary 1MiB 4TiB
(parted) set 1 raid on
(parted) q

# 2) partition /dev/sdc the same way (your /dev/sdX dev names may be different, check dmesg)
# 3) reboot machine

# 4) verify partioning
nas1:root:/home/me> parted /dev/sdb (and sdc)
GNU Parted 2.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) p
Model: ATA ST4000VN000-1H41 (scsi)
Disk /dev/sdb: 4001GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt

Number Start End Size File system Name Flags
1 1049kB 4001GB 4001GB linux-swap(v1) primary raid

(parted) q

# 5) Create RAID 1 Mirror Array
nas1:root:/home/me> mdadm --create --verbose /dev/md0 --level=mirror --raid-devices=2 /dev/sdb1 /dev/sdc1

# 6) Wait for RAID Mirror to finish Synchronizing (about 6+ hours)
nas1:root:/home/me> mdadm --detail /dev/md0
nas1:root:/home/me> cat /proc/mdstat

# 7) Create ext4 File system with some tweaks
# Since I'm storing huge files (Virtual Machine snapshots and copies)
# I really don't expect millions of files or deep directories or any root
# logging info, I disable su reserved space, and limit my inodes to 1M
# (The default mkfs options will eat up a ton of the 4TB usually unneccessarily)

nas1:root:/home/me> mkfs.ext4 -m0 -N 1000000 /dev/md0

# 8) Mount new fs and enjoy 3.7+TB usable RAID 1 space
nas1:root:/home/me> mount /dev/md0 /bigdata

Cisco Small Business 200 Series SLM2008T-NA Smart SG200-08 Gigabit Ethernet Switch
  • Owned For: 1 day to 1 week

Pros: Looks nice

Cons: buggy

Other Thoughts: Known issues with dropping NFS SYN packets. Spent days trying to troubleshoot firewalls and other various components to figure out why NFS simple would not connect only to discover this switch was the problem! After that, I tried to upgrade firmware to and it bricked the switch. Complete garbage.

SAMSUNG 840 Pro Series MZ-7PD256BW 2.5
  • Verified Owner
  • Owned For: 1 month to 1 year

Pros: Very fast. Win 7 laptop boots and is ready to go before I get my reading glasses on and first sip of coffee.

Cons: It's not free

Other Thoughts: If you still run a laptop or PC without at least an SSD boot disk you are living in the stone age. Picked up a refurbed D3LL Latitude with 16GB RAM and demoted slow spinner drive to secondary data drive with optional CD caddy disk tray and added this gem of an SSD. Disabled any paging files. Disabled any browser disk caches. Laptops are actually enjoyable to use now :-)
