i recently got 2 320 gb seagate momentus 7200 rpm laptop drives. I put them in my pc, set them up as raid, and cloned my old raid (which consisted of one toshiba 5400 rpm laptop drive with around 2000 hours on it and a WD 7200 rpm GreenPower AV drive from a dvr with 30,000 hours) onto the seagates and running a speed test on it the read speeds are crap compared to my old raid (i don't have a picture of the speed on the old raid but both drives have a read/write speed of 70 MB/sec with a combined speed of 145 MB/sec). Write speed is good on this. Can anyone explain the read speeds?? the 2 seagate drives have around 8000 pending reallocated sectors and 8000 hours on it. The old drives have no reallocated sectors and are older with way more hours then the seagates.

8000 pending sectors and you did put them in? 

 

Sorry but the lights are on inside of the thinking thing in you head?

 

Don't mean to be rude but this is a no go... For Raid 0 especially because there is no parity and one dying drive kills all your data on the raid span.

Main System:

Anghammarad : Asrock Taichi x570, AMD Ryzen 7 5800X @4900 MHz. 32 GB DDR4 3600, some NVME SSDs, Gainward Phoenix RTX 3070TI

 

System 2 "Igluna" AsRock Fatal1ty Z77 Pro, Core I5 3570k @4300, 16 GB Ram DDR3 2133, some SSD, and a 2 TB HDD each, Gainward Phantom 760GTX.

System 3 "Inskah" AsRock Fatal1ty Z77 Pro, Core I5 3570k @4300, 16 GB Ram DDR3 2133, some SSD, and a 2 TB HDD each, Gainward Phantom 760GTX.

 

On the Road: Acer Aspire 5 Model A515-51G-54FD, Intel Core i5 7200U, 8 GB DDR4 Ram, 120 GB SSD, 1 TB SSD, Intel CPU GFX and Nvidia MX 150, Full HD IPS display

 

Media System "Vio": Aorus Elite AX V2, Ryzen 7 5700X, 64 GB Ram DDR4 3200 Mushkin, 1 275 GB Crucial MX SSD, 1 tb Crucial MX500 SSD. IBM 5015 Megaraid, 4 Seagate Ironwolf 4TB HDD in raid 5, 4 WD RED 4 tb in another Raid 5, Gainward Phoenix GTX 1060

 

(Abit Fatal1ty FP9 IN SLI, C2Duo E8400, 6 GB Ram DDR2 800, far too less diskspace, Gainward Phantom 560 GTX broken need fixing)

 

Nostalgia: Amiga 1200, Tower Build, CPU/FPU/MMU 68EC020, 68030, 68882 @50 Mhz, 10 MByte ram (2 MB Chip, 8 MB Fast), Fast SCSI II, 2 CDRoms, 2 1 GB SCSI II IBM Harddrives, 512 MB Quantum Lightning HDD, self soldered Sync changer to attach VGA displays, WLAN

they were free and were used in a work environment before i got them. I still have the old drives next to me unformatted if these drives fail (I do keep backups)

What are you using to make the raid? Use storage spaces in windows, not the bios.

 

With that many bad sectors, your gonna have a slow drive. You should really tos it if there are bvad sectors.

so they were beaten around a lot, spun up, spun down, hot environment ...these things are time bombs.

Don't use the raid on your board, it sucks. Use storage spaces in windows.

Toss those drives and buy new ones. Thats how you lose data.

too late, i have to clone the data over and i dont think a bootable acronis true image disk will pick up storage spaces volumes

You should clean install windows on a proper drive that works. And don't do raid.

windows is on a seperate ssd. The raid i created solely because i only have access to small hard drives, the plan is to run these seagates into the ground, swap both of them with my 320 gb old raid, and once my old raid dies, ill rob my laptop drive (which is backed up of course)

Backing up the raid to a 1 tb hard drive (which came out of a external drive enclosure as the controller crapped out) and not surprisingly, it has 16 bad sectors instead of 8000. I got 2 backups now, the original raid 0 drives and this 1 tb
