Looking for a RAID card and some FS questions

2 posts in this topic


Currently I have HTPC configured like this;


  • AMD Athlon II x2 260
  • 4GB DDR2 800MHz RAM
  • 1xWD 500GB 7.2k
  • 3xWD Green 2TB in RAID5


  • Win 7 x64
  • XBMC
  • Folder Sync
  • .....

On my array, I mostly save large media files and important family photos (they're also synced to another PC).

The array itself is managed by the on-board RAID controller and is using NTFS.

Now, I want to expand my array, switch to a dedicated RAID card that's future proof and maybe change the FS, although the latter is probably not feasible if I stay on Windows.

I'm fully aware that I'll have to delete the array in order to migrate to another RAID card.

I want to go with Hardware RAID, not any Software solutions like FlexRaid, RaidZ, or any kind of snapshot RAID.

I also want the array to be expandable and the only possible way with HW raid is the OLCE feature, as far as I know.

The NTFS has the array limit of 16TB, is there any way around it? Is it possible to avoid those nasty passive errors that come with storing a lot of data for longer periods of time?

Is it possible to get a raid card with let's say 4 ports and then just buy expansions cards to increase the SATA port count?

Does a raid card I'm looking for exist in the under 150$ range, which one?

To answer you directly:

1. go for 500$ budget


2. go for SW raid

A proper HW RAID card will need a BBU for RAID5, or else cache is limited to read only operations.

Your money is better spent for a UPS with decent software and a SW RAID, especially if you are dealing with media files.

Large sequential reads/writes are handled not-that-bad with SW RAID.

Another point - your drives are Greens. They suffer from TLER problem, which means they will be rejected from a decent HW RAID Controller every now and then.

So if you want to replace drives and buy controller and BBU, then 500$ will be just the start of it...

I am not sure your money is justified with that performance requirement.
