hdd vs ssd vs PCIE nvme vs Sata (speed /price/ iops /reliability)

Before buying or upgrading make sure to check SSD with SATA Protocol (500MB/S)or SSD With NVME protocol (2000MB/S. or even 4gbps.

TIP: make sure your laptop or PC Supports NVME Protocol before buying /upgrading the SSD.

PCIE NVME VS M.2 NVME vs M.2 SSD

The PCIe interface is generally faster, as the SATA 3.0 spec is limited to around 600MB/s maximum speed, while PCIe Gen 2 x2 lanes are capable of up to 1000MB/s. And if you think that’s a large difference, PCIe Gen 2 x4 lanes are capable of up to 2000MB/s, and PCIE Gen 3 x4 lanes of up to 4000MB/s.

Price: m.2 SSD cheaper and slower,

NVME introduced in 2013 to attach to the PCI Express (PCIe) slot on a motherboard instead of using SATA bandwidth.

m.2 nvme vs m.2 sata

TIPS to Identify NVME SSD or SATA SSD On your PC or Laptop

NVME SSD Bootup faster almost Instantly, while SATA SSD even its m.2 form factor its boot up slow you can starting screen loading on windows. other way go device manager or task manager etc.

HDD VS SSD VS SSHD speed / throughout

Type	Speed r/w (sequential)	IOPS (random)read (industry level)	iops Random writes	Price 1TB
RAM Bandwidth	2400MHZ 24gbps	na	NA	NA
SSD nvme	3gbps to 6gbps	check product label		INR 13k to 18K $200
SSD SATA	500 mb to	98K*	90K*	inr 10K $130
SSHD	NA 200*
HDD	100-160 mb/s	100-400 IOPS		INR 2000 or $50

Note: Nme Protocol type SSD not popular as Sata SSDs. So Price dropped equal to Sata but speed Difference is 500mbps vs 2500Mbps. 5x faster.

nvme better for enterprise level ie hosting companies. gaming pc need this type too.

PCIE Slot gen 3 or gen 4 slots Has to check before buying.

Things to check before buying a SSD

Old PC or Laptops SATA Protocol 2.5 Or 3 (Ex Sata 2.5 SSD at 500Mbps actually giers 200Mbps lower version protocol)
Is your PC / laptop supports Nvme Protocol
M.2 slot Protocol sata or nme
when buying m.2 SSD check whether it Sata or nvme
SSHD not good instead try SSD and HDD
installing SSD as 2nd drive in laptop in dd drive slot (check the Caddy tray size 9 or 12mm)

256 gb ssd = 4tb hdd “(16x) = $160

HDD Speed Rpm: 65K to 72K Rpm

SSHD = ssd+HDD

SSD Throughput, Latency and IOPS

Latency:

storage device to start an IO task called latency

IOPS:

how many Input or Output (IO) operations can be performed by the storage device every second, or IOPS

The greater the number of IOPS, the better the performance.

Speed /Throughput :

The speed at which data is transferred out of or into the storage device is measured in Megabytes per second.

an 80x improvement

50/50 workload ratio of read/write and 12 drives in the array, for a RAID 6 configuration the usable capacity would be 4.7 TB—and the I/O performance would be 429 IOPS. A RAID 5 configuration would be the same usable storage, but IOPS increases to 600 (thus the meaning of the term “RAID Penalty”).

Apply the same configuration in terms of the same number of SSD drives, the same total usable capacity and a 50/05 workload, and the IOPS climb to 34,286 for RAID 6 and 48,000 for RAID 5. That is nearly an 80x increase at RAID 5 and RAID 6 over the HDD.

ssd vs hdd reliability

Hard drives with moving parts they will die eventually, they give warning signs like I if your hard drive is making clicking noises.

SSD:contain no moving parts

MTBF (mean time between failures) i

a hard disk drive may have a mean time between failures of 300,000 hours, while an SSD might have 1.5 million hours.

TBW — Terabytes written is the total amount of data that can be written to an SSD before it is likely to fail. here are the

Samsung 860 EVO 256 gb SSD: 150 TBW

P/E cycles — data erased, and then rewritten. between 500 to 100,000 P/E cycles.

How to use HDD & SSD Together in laptop & desktop

use 2nd Laptop CD ROM to insert 2nd HDD.

for this buy ssd with hard drive caddy for laptop

SATA 2nd 2.5” Hard Drive Caddy For 12.7mm :
SATA 2nd 2.5” Hard Drive Caddy For 9.5 mm :

for this find dvd drive height: go device manager >> find dvd model>> search specs.

Clone c drive which has windows pre installed, using mini partition tool wizard software

Go to bios settings select primary boot device as ssd.

after boot up format hdd data.

use ssd for regular application, hdd for storing movies and files. if you are using edit purpose make sure to bring to ssd for faster read & writes.

Please comment! so i can update it regularly.
