Pretty good for hdd's.

Do you have disk indexing disabled? Are those in RAID 0? Whats your stripe size? Eight of them right?

My single Seagate Barracuda 500gb.

Its a few years old install, pretty sure I disabled indexing. Raid 0, thought I had 8 but its 6 in raid 0 and two pass thru drives. Stripe is 4k.

As far as life length....It will last long enough that when its too old to use, the technology will be so obsolete that you'll want something else anyway.
The indilinx controller drops in speed when doing s a sustained transfer of over 50% free space reminaing , not once it is 50% full. EG When empty if you transfer 300GB to the 512GB drive teh first 256GB transfers at full speed the remainder drops in performance

Another EG... the drive is 256GB full. you will have full performance with writes up to 128GB in transfer space. 200GB would run 128 at full and the remainder at reduced rates. (about HDD speeds)

this only effects write speed BTW...

Read performance is never effected by amount of data on the drive.

Write performance will remain consistent up to the size of the nand used on the PCB.
If 8x16GB NANDs are used the drive performans flawlessly until less than 16GB remains free. After that point it can no longer write equally to all nand cells. Bear in mind it STILL does. so performance does not drop a hell of a lot.

the Vertex 4 drives are the only drives that i know that drop from sustained writes...



Had to go back a ways to show a aida64linear write chart. owc eXTREME PRO 6g



Perfect performance from start to finish. thats the sandforce controller though not the marvell, I mean indilinx used in the Vertex 4




While it is true that SSDs will drop in performance a small amount as they fuill up it is no where close to how much HDDs do.
