The WD Red drives are 5400RPM drives. Here’s some benchmarks comparing both the WD RE and WD Red drives we just conducted last week.
4x Drives RAID 5 – Using Macbook PRO connected to the Areca ARC-8050 Thunderbolt Unit.
WD RE (WD4001FYYG)
Read – 375MB/s
Write – 530MB/sWD Red (WD30EFRX)
Read – 211MB/s
Write – 489MB/sNo surprise, the 7200RPM WD RE drives are much faster.
And, if your wondering how the WD RE compares with the Hitachi Ultrastar, here’s the benchmark numbers we got.
Hitachi Ultrastar
Read – 342MB/s
Write – 525MB/sThe performance of the WD RE and Hitachi Ultrastar are very similar, Again no surprise since they do share the same overall design and both use the 5x 800GB platters. It comes down to user preference, mine is the WD RE.

“there was a blown sector in drive one (the thing is one week old) and they would send out a drive replacement”
Not suprised since there using desktop drives. Although enterprise level drives are not immune from such problems, but at least they are less likely to run into these type of issues.

[Alex Geroulaitis] “I’d love to test it out though to see how it performs in RAID0 over USB 3.0. It might do 400MB/s!”
Which USB 3.0 card do you recommend? I could never turn away a challenge. =)

Although it is always recomended to use the same specification drive when creating a RAID array, using different drives will result in only operating as fast as the slowest drive. Would it be a bad idea?…In your case, Not at all. Since your only using 2 drives in RAID 0, the different cache just doesn’t make a difference. Drive cache would be more important perhaps in a very large server/storage envronment with more IO requests.

[Alex Geroulaitis] “G-Technology: congratulations! You can now use Black Caviars for G-Drive”
[Bob Zelin] “I have had much better success with the Hitachi enterprise ultrastars than the Black Caviars (although both are good”Black Caviars in a RAID environment…really? You are aware that these are “desktop” drives? When an error is found on a desktop hard drive, the drive will enter into a deep recovery cycle to attempt to repair the error, recover the data from the problematic area, and then reallocate a dedicated area to replace the problematic area. Most RAID controllers allow a very short amount of time for a hard drive to recover from an error. If a hard drive takes too long to complete this process, the drive will be dropped from the RAID array. The Black Caviars don’t support TLER (Time Limited Error Recovery) which is available only in there RE series (enterprise level drive), eliminating the hard drive from entering into a deep recovery cycle. The hard drive will only spend 7 seconds to attempt to recover. This means that the hard drive will not be dropped from a RAID array.
From experience, 90% of failures or issues I see always involve “desktop” drives.

It’s more like only two major players now, WD and Seagate. Who uses Samsung, Fujitsu or Toshiba drives anyways?
I agree with Bob, this is a sad time. Seagate started having alot of issues after they aquired Maxtor a few years back, I hope the same is not said for WD. Will be keeping my fingers crossed!

Walter,
That would be the Areca ARC-1221X you are referring to. Areca has a complete line of RAID controllers, there are many models available, but the ARC-1221X is the card mostly used for external storage in DV applications.

Our test have shown better performance with the ARC-1231ML in SATA environments when compared with the 1680 SAS Controller series.
The IOP341 is just designed and optimized for SATA drives, than the IOP348 chipset.

Although the Areca ARC-1680ix-12 is the latest and greatest SAS/SATA RAID Controller. The ARC-1231ML SATA RAID Controller is still the best performance choice when using 12 SATA drives. The ARC-1680ix-12 really outshines the ARC-1231ML in SAS drive environments only.

Yes, I don’t think they would be willing to provide the card to us for comparision test. I think we all know the results will not favor them.
And, No. We have not had a chance to test the Highpoint RocketRAID 3500 series cards.
