What We Like About the Samsung T9 Portable External SSD 4TB (MU-PG4T0B/W)

2,000 MB/s in both directions: the write figure matches the read figure, rather than the lower sustained write common on portable drives
USB 3.2 Gen 2×2 at 20Gbps: double the 10Gbps ceiling of Gen 2×1, which is what the 2,000 MB/s rating needs to be reachable
AES 256-bit hardware encryption: handled on the drive rather than in software, so it does not consume host CPU cycles
3-metre drop rating at 122 grams: rated for drops in an 88 x 60 x 14 mm enclosure
Five-year limited warranty: covers the drive for longer than the three years typical of portable SSDs

Interface & Transfer Speeds

The T9 connects over USB 3.2 Gen 2×2, rated at 20Gbps. Samsung quotes sequential reads of up to 2,000 MB/s and sequential writes of up to 2,000 MB/s, and states the drive holds high speeds through longer transfers rather than only in short bursts. UASP mode is supported.

Reaching the full 20Gbps requires a host port that also supports USB 3.2 Gen 2×2. On a 10Gbps Gen 2×1 port the drive still works, at that port’s lower ceiling.

Capacity & Compatibility

Rated capacity is 4TB, counted by Samsung as 1TB = 1,000,000,000,000 bytes, so the figure reported by an operating system will read lower.

Samsung lists compatibility with PCs, laptops, Android smartphones and tablets, game consoles, smart TVs and cameras, across Windows, macOS and Android, including cameras shooting up to 12K.

Encryption & Software

Security is handled by AES 256-bit hardware encryption. Samsung Magician software manages the drive, covering firmware updates, encryption setup and drive health monitoring.

Thermal & Durability

Samsung fits what it calls Dynamic Thermal Guard, which the company states controls heat to hold the drive at its intended operating temperature during heavy use. The drive is rated to withstand drops of up to 3 metres.

Operating temperature range is 0°C to 60°C, with a non-operating range of -40°C to 85°C. Samsung states the drive is designed in compliance with international safety standard IEC 62368-1.

SanDisk Optimus 5100 NVMe SSD 1TB (SDSP51100TAN-000E0) Launched in India – PCIe 4.0 x4, 7,100MB/s Read, 6,700MB/s Write, 600 TBW, 500GB and 2TB Models Also Listed

SanDisk has launched the Optimus 5100 NVMe SSD 1TB (SDSP51100TAN-000E0) in India. The drive is an M.2 2280 internal SSD on a PCIe 4.0 x4 interface, rated for sequential reads of up to 7,100MB/s and sequential writes of up to 6,700MB/s.

The price currently showing against the SanDisk Optimus 5100 NVMe SSD 1TB (SDSP51100TAN-000E0) listing is the MRP, not the launch price: Rs.85,700. The actual launch selling price is expected to be lower, and the Amazon India listing is expected to be updated with the launch price in the coming days, so it is worth checking the product page again after a few days.

Note: why SSD prices are this high right now: DRAM and NAND contract prices have risen steeply through 2026 as AI data centre buildouts absorbed supply and manufacturers shifted capacity to server parts, which has pushed consumer SSD prices up sharply.

Key specs highlights include 1M IOPS random read and 1.3M IOPS random write, 8th generation SanDisk BiCS QLC 3D CBA NAND, a 600 TBW endurance rating, and a 5-year limited warranty.

A second Optimus 5100 configuration is also in stock on Amazon India, the 500GB model (SDSP51500GAN-000E0), built on the same M.2 2280 PCIe 4.0 x4 board with sequential speeds of up to 6,600MB/s read and 5,600MB/s write, listed at Rs.11,809 against an MRP of Rs.47,600 (Amazon India↗).

Quick Links

What We Like About the SanDisk Optimus 5100 NVMe SSD 1TB (SDSP51100TAN-000E0)

7,100MB/s sequential read: close to the practical ceiling of the PCIe 4.0 x4 interface the drive runs on
1.3M IOPS random write: the highest random write figure in the Optimus 5100 range, matched only by the 2TB model
600 TBW endurance: double the rating of the 500GB model, with the warranty running 5 years or that limit, whichever comes first
3.9 W average read and write power: lower draw than the 2TB and 4TB models in the same range, which matters in a laptop M.2 slot
TCG Pyrite 2.01 with ATA Security passthrough: drive-level security support without a separate utility

Performance and Interface

The 1TB SDSP51100TAN-000E0 sits at the top of the Optimus 5100 range for read speed alongside the 2TB model. SanDisk rates it at 7,100MB/s sequential read and 6,700MB/s sequential write on 1MB transfers at queue depth 8 with a single thread.

Random performance is quoted at 1M IOPS on 4KB reads and 1.3M IOPS on 4KB writes, both measured at queue depth 32 across 16 threads. The 500GB model drops to 660K IOPS read and 1.1M IOPS write, so the 1TB capacity is the first step in the range where the drive hits its full random read figure.

The interface is PCIe 4.0 x4 with NVMe, and SanDisk lists backwards compatibility with PCIe 3.0 x4, x2 and x1 as well as PCIe 2.0 x4, x2 and x1. Slotting it into an older Gen3 machine will work, at Gen3 speeds.

NAND, Cache and Storage Design

Storage is 8th generation SanDisk QLC 3D CBA NAND. There is no onboard DRAM: the drive uses Host Memory Buffer, borrowing a slice of system RAM for the mapping tables instead of carrying its own DRAM chip.

The SLC write cache is SanDisk’s nCache 4.0. According to SanDisk, the technology is what handles application multitasking and large file copies on the drive.

Endurance, Reliability and Warranty

The 1TB model carries a 600 TBW endurance rating, calculated on the JEDEC client workload (JESD219). Across the range the figure scales with capacity: 300 TBW at 500GB, 600 TBW at 1TB, 900 TBW at 2TB and 1,200 TBW at 4TB.

MTTF is quoted at up to 1.75M hours for every capacity, based on SanDisk’s internal Telcordia SR-332 stress testing at 25°C. The 5-year limited warranty runs for five years or until the TBW limit is reached, whichever happens first.

Power Draw and Environmental Limits

Average power on the 1TB model is 3.9 W on reads and 3.9 W on writes, measured with IOMeter 1.1.0 over a 10 second moving average during burst operations. Idle (sleep) draw is 4 mW, the same as the 500GB and 2TB models, with the 4TB model rising to 4.5 mW.

Operating temperature runs 0°C to 85°C, with a non-operating range of -40°C to 85°C. Operating vibration tolerance is 5 gRMS over 10-2000 Hz on three axes, non-operating vibration is 4.9 gRMS over 7-800 Hz, and shock tolerance is 1,500G at 0.5 ms half-sine.

Security and Bundled Software

Security support covers TCG Pyrite 2.01 and ATA Security passthrough over NVMe.

Two software downloads are listed with the drive. The SanDisk Dashboard application, Windows only, handles performance monitoring and firmware updates. Acronis True Image for SanDisk is offered free for data migration onto the new SSD, and SanDisk notes a separate cable or enclosure may be required. The Acronis license runs five years and has to be redeemed within 90 days of purchase.

Form Factor and Compatibility

Every capacity in the range uses the same M.2 2280 board measuring 80mm x 22mm x 2.38mm and weighing 5.7g. SanDisk allows for a variance of ±0.15mm on length and width and ±1g on weight.

Compatibility is listed as Windows 10 or newer, a PCIe 4.0 x4 interface and an M.2 2280 port. The drive is RoHS compliant and carries BSMI, CAN ICES-3(B)/NMB-3(B), CB-Scheme, CE, FCC, KCC, Morocco, RCM, TÜV, UL, VCCI and UKCA certifications.

Other Optimus 5100 Model Numbers

Three of the four capacities have reached Amazon India. The 2TB model (SDSP51200TAN-000E0) has a live listing with no price information attached to it at the time of writing, and shares the 1TB model’s 7,100MB/s read and 6,700MB/s write ratings. The 4TB model has not appeared yet, and going by the pattern of the other three it will probably follow.

What We Like About the SanDisk 520 SATA SSD (SDSS51500GAB-000G0)

SATA III 6Gbps with backwards compatibility: works in SATA I and SATA II systems, which covers older desktops and laptops being upgraded from a mechanical drive
2.5-inch / 7mm cased design: the standard drive bay size, so it drops into most notebooks and desktop bays without an adapter
300 TBW endurance on the 500GB model with a 5-year limited warranty: the warranty runs to 5 years or the TBW limit, whichever comes first
No moving parts and a 1,500G shock rating: the drive has no mechanical assembly to fail on impact
Secure boot and secure firmware update support: both are handled at the SATA interface level

Interface, NAND and Cache

The 520 SATA SSD connects over SATA III at 6 Gbps, and SanDisk lists it as backwards compatible with SATA I and SATA II.

Storage is SanDisk TLC 3D NAND. There is no DRAM cache on this drive. An SLC cache is present across all four capacities.

Sequential and Random Performance

Read speed is quoted at up to 560MB/s on every capacity in the range. Write speed varies by model: the 500GB is rated at up to 510MB/s, the 1TB and 2TB at up to 520MB/s, and the 4TB at up to 525MB/s.

On random performance, the 500GB model is rated at up to 78K IOPS read and up to 73K IOPS write.

Capacity	Sequential Read	Sequential Write	Random Read	Random Write
500GB	560MB/s	510MB/s	78K IOPS	73K IOPS
1TB	560MB/s	520MB/s	89K IOPS	74K IOPS
2TB	560MB/s	520MB/s	89K IOPS	75K IOPS
4TB	560MB/s	525MB/s	85K IOPS	76K IOPS

SanDisk states these figures come from internal testing, and that performance varies with the host device, usage conditions and drive capacity.

Endurance and Reliability

Endurance is rated per capacity, so the figures scale with the size of the drive:

Capacity	Model Number	Endurance (TBW)
500GB	SDSS51500GAB	300 TBW
1TB	SDSS51100TAB	400 TBW
2TB	SDSS51200TAB	700 TBW
4TB	SDSS51400TAB	1,000 TBW

The Amazon India listing title quotes “Up to 1000TBW Endurance”, which is the figure for the 4TB model. The 500GB model listed here is rated at 300 TBW.

MTTF across the range is quoted at up to 2.25 million hours. SanDisk notes the TBW values are calculated using the JEDEC client workload (JESD219), and that the MTTF figure comes from internal Telcordia SR-332 stress testing on a sample population rather than a prediction for any individual drive.

Warranty is 5 years limited, or the maximum TBW endurance limit, whichever comes first.

Power Draw

Power State	500GB	1TB	2TB	4TB
Average Active	0.97 W	1.01 W	1.05 W	1.09 W
Max Read Operating	1.51 W	1.49 W	1.52 W	1.8 W

Samsung T7 Shield & T7 Portable SSD (MU-PE1T0S/W, MU-PE1T0R/W, MU-PE2T0R/W, MU-PC1T0T) Launched in India – IP65, 1,050MB/s, PCIe NVMe

Samsung has launched the T7 Shield Portable SSD in India. The rugged external SSD price starts at Rs.28,699 (Lowest Price on August 13, 2026) for the 1TB variants, with the 2TB variant at Rs.56,999. The MRP price is Rs.40,899 and Rs.81,699 respectively.

The standard Samsung T7 Portable SSD (MU-PC1T0T) in 1TB is listed at Rs.27,158 against an MRP of Rs.39,199.

Key highlights include an IP65 rating for water and dust resistance, USB 3.2 Gen 2 connectivity, read and write speeds of up to 1,050/1,000 MB/s, and PCIe NVMe internal hardware.

The T7 Shield is listed in Blue and Black, and the standard T7 in Grey.

Pricing & Availability

Variant	Launch Price	MRP
Samsung T7 Shield 1TB (MU-PE1T0S, Black)	Rs.28,699	Rs.40,899
Samsung T7 Shield 1TB (MU-PE1T0R, Blue)	Rs.28,699	Rs.40,899

Samsung T7 1TB (MU-PC1T0T, Grey)	Rs.27,158	Rs.39,199

What We Like About the Samsung T7 Shield Portable SSD

IP65 water and dust resistance — the rating covers dust ingress and low-pressure water jets, which the standard T7 does not carry
Up to 1,050/1,000 MB/s read and write — sequential speeds that use the full USB 3.2 Gen 2 10Gbps interface rather than a 5Gbps link
PCIe NVMe internal hardware — the drive uses NVMe rather than the SATA bridge found in older portable models
Capacities from 1TB to 4TB — the range covers single-drive storage for large video and photo libraries
Cross-platform compatibility — Samsung lists support for PC, Mac, Android devices and gaming consoles

Durability & IP65 Rating

Where the T7 Shield differs from the standard T7 is the enclosure. Samsung rates it IP65 for water and dust resistance, and lists drop resistance alongside it. The company positions the drive for field use by photographers and content creators — work where the drive is carried between locations rather than left on a desk.

The standard Samsung T7 (MU-PC1T0T) does not carry the IP65 rating. That is the main separation between the two lines at the same capacity, and it currently accounts for a difference of about Rs.1,500 — the 1TB T7 Shield at Rs.28,699 against Rs.27,158 for the 1TB T7.

Transfer Speeds & Interface

Both lines connect over USB 3.2 Gen 2, which tops out at 10Gbps, and both are rated for sequential reads of up to 1,050 MB/s and writes of up to 1,000 MB/s. Samsung states this makes the drives almost twice as fast as the previous T5, and attributes the speeds to the PCIe NVMe hardware inside the enclosure.

Samsung also lists direct Ultra High Resolution video recording onto the T7 — 4K at 60fps from a connected camera or mobile device, including iPhone 15 Pro Res 4K at 60fps.

Capacities & Compatibility

The T7 Shield range runs from 1TB to 4TB. On Amazon India, the 1TB and 2TB variants are the ones currently listed, in Black and Blue.

For compatibility, Samsung lists PC, Mac, Android devices and gaming consoles. Both lines use a USB Type-C connector on the drive.
