Highly advised harddrive strategy

If you choose RAID 1 (mirroring), please mind, that it is not a good strategy to use two hard discs of the same type and from the same product line. See page 9 of the manual. RTFM

Recommended HDDs

Preliminary remark

As of December 2008 there is still a major problem with harddrives by Samsung. Don't get them in combination with the IB-4220-B, it's very likely to be a problem. Almost the same has to be said for Western digital drives, although the certainty of failure seems to be less. However, to avoid the risk of data-loss, avoid hdds of these two brands in combination with this box, up to firmware 2.6.3.1.

Hitachi

• HITACHI Desktar 7K1000 750Go SATA 3.0 Gbps, works well in RAID 1
• 500 GB Deskstar T7K500, HDT725050VLA360
• 500 GB Deskstar P7K500, HDP725050GLA360
• 1000 GB Deskstar 7K1000, HDS721010KLA330
  mainboard is overheating (>50°C) therefore the fan is really noisy, Spindown operational without fix too.

Maxtor

• 250 GB MaXLine Plus II
  Older harddrive especially designed for the use in NAS systems and 24/7 usage. Works fine in a RAID 1 mode.
• 250 GB DiamondMax 21, STM3250310AS
• 250 GB MaXLine Plus II, 7Y250M, Spindown operational using a fix
• 500 GB MaXLine Pro 500, 7H500F0

Samsung

As of December 2008 there is still a major problem with harddrives by Samsung. Don't get them in combination with the IB-4220-B, it's very likely to be a problem. Until further notice drives by Samsung cannot be considered safe.

• 500GB 3.5" Samsung HD501LJ
  It's working only in combination with 1 hdd of another brand, but you have no guarantee for this.
  See further comments in the Reported Errors section.

Seagate

• 160 GB Barracuda 7200.9, ST3160811AS, geringe Lärmentwicklung, Wärmeentwicklung ca. 43°C

• 500 GB Barracuda 7200.11, ST3500320AS
  Works well in Raid 0, RAID 1 & JBOD (low noise; very low temperature - max. 32°C)
• 500 GB Barracuda 7200.10, ST3500630AS
• 750 GB Barracuda 7200.10, ST3750640AS
  low temperature, low noise and without of any fault
• 1000 GB Barracuda ES.2, ST31000340NS, low temp, low noise and stable

Western Digital

As of December 2008 there is still a major problem with harddrives by Samsung. Don't get them in combination with the IB-4220-B, it's very likely to be a problem. Almost the same has to be said for Western digital drives, although the certainty of failure seems to be less. However, to avoid the risk of data-loss, avoid hdds of these two brands in combination with this box, up to firmware 2.6.3.1. So the following list should be regarded as outdated until further notice.

• 200 GB Western Digital Caviar 6L200M0 (SATA150)
• 250 GB RE, WD2500YS
• 250 GB Caviar SE16, WD2500KS, using two hard drives, low noise

• 500 GB RE2, WD5000YS, bei 2 Platten geringe Lärmentwicklung, ca. 35°C-40°C, S.M.A.R.T. = OK
• 500 GB RE2, WD5000ABYS, RAID 1 or SPAN Mode, low noise, about 40°C, no errors
• 500 GB RE3, WD5002ABYS, RAID 1 Mode (PCB@1.2, Firmware@2.6.3.1), so far no problems
• 500 GB Caviar GP WD5000AACS, extremely low noise, power consumption 3,3 W in idle.
• 500 GB 3,5" Western Digital Caviar SE 500 GB SATA 3.0 Gbps (WD5000AAJS & WD5000AAKS)
  Single disc without RAID (SE is not designed for RAID), works very well though, ultra-low noise, about 42°C, error-free.
• 750 GB RE2, WD7500AYYS
• 750 GB Caviar SE16, WD7500AAKS, CRC errors with mainboard v1.1
• 1000 GB Caviar GP, WD10EACS, using two hard drives, low noise, about 35°C
• 1000 GB Caviar GP, WD10EACS, using two hard drives, low noise, RAID1, bottom HDD 40°C, upper HDD 41°C (4 hours uninterrupted data writing)

Reported Errors

Notice: Incompatible HDDs

Please discuss your incompatibility problems at forum first. If you have any issues check your mainboard version.
Since 02/2008 the RaidSonic offers new mainboard v1.2 (see forum for more details).

Western Digital

• 500 GB RE2, WD5000ABYS, RAID 1
  The second hard disk will be mount after reboot and RAID record is lost and has to be rebuild (time-consuming procedure).

Note: Mainboard in Hardware-Revision 1.2 solved the problem.

Maxtor

• 250 GB DiamondMax Plus 9, 6Y250M0: Drive not recognised by units with v1.2 mainboard

Samsung

• 160 GB Spinpoint S166, HD161HJ mount only rarely.
• 200 GB Spinpoint P120, SP2004C mount only rarely.
• 200 GB Spinpoint S250, HD200HJ im 1.5- & 3Gb/s-Modus is never mount.
• 250 GB Spinpoint P120, SP2504C as standalone is generally mount, data loss in RAID 1. Spindown operational.
• 320 GB Spinpoint T166, HD320KJ im 3Gb/s-Modus
  Hard drive not mount. Mount after reboot as a result of switching to 1.5G b/s mode using a jumper.
• 400 GB Spinpoint T133, HD400LJ
  The hard drives are sporadic not mount in RAID or JBOD mode. System log message: "The disk occur wrong. Please power off and exchange disk". No SMART errors.
• 400 GB Spinpoint T166, HD403LJ
  The hard drives are sporadic not mount in RAID or JBOD mode. No remedy using 1.5 Gb/s mode. Imponderable effect after warmboot or coldboot.
• 500 GB Spinpoint T166, HD501LJ im 3Gb/s-Modus
  Two hard drives in SPAN (NRAID) or RAID 1 mode, max. 37-40°C. Regularly failures, hard drives not mount! System log message: "The disk occur wrong. Please power off and exchange disk".
• 750 GB Spinpoint F1, HD753LJ im 3Gb/s-Modus
  Hard disk not mount. No effect in 1.5 Gb/s mode. Firmware 2.6.0.IB.1.RS.1.

Further info - these disks will not mount on cold boot, only after a re-boot. As previous poster indicates, setting them to 1.5 Gb/s via firmware (there are no jumpers on this drive!) does not improve the situation.

• 1000 GB Spinpoint F1, HD103UJ im 3Gb/s-Modus
  Two hard drives installed but only one is mount. RAID not operational.

Combinations

• 500 GB Samsung Spinpoint T166, HD501LJ (in 3Gb/s mode) + 500 GB Western Digital RE2 (WD5000ABYS)
  The Samsung HDD will be mount pending reboot.
• 250 GB HDS722525VLSA80 (hda/boot disk) 1.5gbps + 750 GB WDC WD7500AAKS 3.0Gbps (hdb/ide2) on mainboard v1.2 with firmware 2.6.0-n(2007-10-11) - have experienced complete loss of all settings and shares (once) / various lockups while data transfers taking place / occaisions where device not seen on network after boot. However, no data corruptions are apparent so far.
