They seem virtually identical, except one is $69 and the other $99, with no discounts on either. The HE103SJ seems like a new model, since it only has 1 review. Other than a .03 difference in latency, they seem the same.
On a slightly different track, I can probably do just fine with the 500 GB version, as I only have about 116 GB of data. Are there any advantages to getting the smaller, single-platter drive?
Well, from what I can tell, the F3R HE10SJ is the new RAID version, hence the "R" added to F3, which I hadn't noticed before. If that's the only difference that seems like a steep price difference, although RAID isn't a concern for me since I use NAS.
the single platter 500gb will generate less heat than the multiplattered drive otherwise there is no real difference. I've run two of the 1tb HD103SJ drives in a raid 0 with no issues for about 3 months now.
this is how I roll:
storage: SAMSUNG Spinpoint F3 HD502HJ 500GB 7200 RPM 16MB
boot: OCZ Technology 60 GB Vertex 2 Series SATA II
Do you run games and apps on your boot or your storage? I was thinking of running a Crucial C300 128 for OS and apps, and 2 X HD103SJ RAID 1 for storage. For the storage, I was also glancing at the Spinpoint F4 HD204UI 2TB, but wasn't sure if a 5400 storage drive would take away any of the added gain from the SSD OS/boot drive.
